Re: Erix fossil (Was Re: games)
It seems there is some talk about the driver that comes with Erix... As far as I know the driver should work with the ASCII RS232C interface (only first channel), it at least works with the SONY RS232C interface which is ASCII compatible. I must say that I do not remember any previous complaints about the driver not functioning with the ASCII interface. The Gradiente interface is another story, a long time ago I have heard about this interface, but I do not have the specs or the hardware. So it is hard to develop a driver for it. If there is still a need for such a driver, I could make it. At least, when I receive the specs from someone...

Re: Looking for a slotexpander
I have the Service Manual of the 8280, but I do not know for sure if it is really complete. Some day I will scan it and convert it to a PDF file. I have just a copy of an original one.

But unfortunatly they have just stopped the documentation service one or two years ago. At least, that is what my colleagues tell me, and they do not like it either. Since the schematics are more than 10 years old, it might be lost forever due to the nice fact that service docs of Philips products is done by an external company. Greetings from Erik Maas p.s.

Re: Looking for a slotexpander
Umm... it seems to me that if it was published it was meant for the common good, and therefor has no copyright at all. It would be useless to publish a copyrighted design, because then it's completely useless. Well, maybe the author wanted to boost or something, but somehow I doubt that. Ehhh... I do not think so, you may learn from it, but you may not steal from it. I think almost every magazine/software/hardware has something in it that will tell you that you may not copy, re-publish, modify, etc. If I remember well, the purpose of the article about the slotexpander in the MCM was to document the slotexpander for people who want to repair it. This had something to do with the reduced activities of the hardware people behind the slotexpander. So, the purpose was to enable people to repair the interface, and not to give it away for re-production. At least, I remember it that way. But another nice example, you know CSS??? The content protection mechanism of DVD? Someone has hacked some code out of a Xing mpeg player and used it to decrypt the DVD stream. The sourcecode of the DeCSS program is used as evidence in the lawsuit. They do not try to punish him for hacking, but for using copyrighted software and keys. One of the nicest thing about this evidense is that al the papers are published on the net, this including the sourcecode of DeCSS. Do you dare to re-use this sources to make a nice program around it? If the copyrights are removed by just publishing it, you could use it. But I do not think it will work this way!

Re: Looking for a slotexpander
The Elektuur version is not made to the MSX standard. By the way, more MSX developments that were published by Elektuur suffered from serious problems. There is a signal on the MSX cartridge connector that is called BUSDIR. On some computers this is not a problem. This signal controls the databus buffers. If it is not driven while doing a read access to the hardware it might put data on the cartridge connector, but it will never reach the Z80. I have nearly all Elektuurs since the beginning of the seventies and it is already raining.. Interesting, I wish I had these years ago... although time is moving on and many new possibilities are appearing for hardware development... Still i do remember having seen a slot expander somewhere in one of the wellknown magazines like MCM. That is true. But since it was published by MCCM, they might have some copyrights on this. If the copyright is not theirs (they did not make these schematics) it could be property of the following clubs/persons: * MK, as they were the first (?) to really produce this design and make improvements * I do not remember the name of MK's designer anymore, but it could be his as well. * Gouda continued with the same expander, so maybe they own it now But apart from this, I have heard some rumours that it was not even developed by MK... Hmmm... this discusion does not help very much... I think what has to be done is making/buying a slotexpander. Sunrise has a slotexpander, but it is not in stock anymore. But they could make some. You could also try MSX Power Replay, but it seems they do not produce normal MSX expanders anymore. (Looks like they only produce it for the Z380 project, and the text suggests that you cannot use this expander on 8-bit computers?) So, it might be the easiest to get it second hand, and that is not easy at all! The library in Tilburg keeps Elektuurs only 10 years... The Elektuur MSX project book is also not available anymore. Maybe it's time (if not too late) to start collecting all hardware articles and schematics from various sources on a central web site, before they're gone forever. It would be a good idea to put all this information on a CD and sell these for about NLG 5,- (or 10,-) just to spread the information as complete and wide as possible BTW the chances are good that it's raining this weekend :-) Did it rain?

Re: Manuals .htm
Also, acrobat ... (don't know the name) includes a printer driver, so that any program's output can be put into a .pdf (also HTML) A backdraw to .PDF is that it is not easily searchable like HTML or TXT As far as I know this is no problem at all, PDF files can contain text. This text is selectable, and you can search for words. You can even add a table of contents and links. Acrobat is also good in recognizing text and figures, with this you have two options: * Let acrobat replace as much as possible by text, this is good for your filesize * Let acrobat place hidden text on the graphics, so that there will not be any visible differences with your original scanned image, but you can select text. Sometimes acrobat can not recognize the text, changes the font where it should not change and can even mess up figures. The drawback is the large filesize. (But compresses most of the time better than e.g. jpeg with the same visual quality) For Linux PDF should not be a problem, I do not know what tool I used, but I could view them without any problems. It was one of the tools debian 2.1 installed on my system. (Now I use suse 6.2, but I have not tested it with this) So, I personally like PDF a lot better than postscript.

Re: Harddisk and CDrom drive under MSXDOS2
Hello Pierre, BTW this serial link is very slow. File transfers using Erix on the MSX side and Telix on the PC are aborted if the baudrate exceeds 9600 bps. This seems strange, considering that there is a fast 16550 UART on both sides. The MSX is running on 7,16 MHz but switching back to 3,58 MHz doesn't help, so it probably isn't a timing problem. This should not happen at all Are you sure hardware handshake is implemented in your null-modem cable, and that the software on the PC uses it? Otherwise, it might happen that buffers overflow when using Y-modem-G-batch. With normal Y-modem-batch there should be no problem. If there still is a problem, another terminal program on the PC could help, or maybe there is a problem in the RS232C interface design. (my fault I guess) If I have time and feel happy to do it, I might write some kind of file-commander over a serial link sometime. But since I do not have much time, it could be this project will never start at all... Greetings from Erik Maas MSX Mailinglist.

Re: Memory Mapper mirror effect?
Anyone knows if there are memory mappers with mirror effect (i.e., for example, a 128k mapper (8 pages), if I select page 16, I'll get page 8). I don't know any, but maybe there is... All mappers do this 'mirroring'... If they didn't then it would not be possible to detect the mappersize... (only legal mappersize-detection is done by using the mirror-effect). No! This is not the correct way to detect the mapper size!!! As a matter of fact, the turbo-R does not have 2^x mapper pages accessible when running in R800-dram mode!!! 4 pages are reserved to store bios, basic and kanji (thought these were the ones) in to speed up the execution, because ROM is not as fast as RAM. The access to these pages is disabled by hardware. Even a turbo-R has the 'mirror' effect, but you can not say that this is the only thing you have to look at to determine the number of mapper pages. By the way, there is a trick to alter these pages: * switch to R800-ROM and these pages are accessible * make changes (e.g. replace KANJI with KUN, I use this method now and then) * and switch back to R800-DRAM H... Here comes a nice thing, not related to this subject, but I have noticed that access to the internal ram of the turbo-R is faster than access to external memory/ram. So it is faster to run KUN-Basic in place of the kanji-ram-place than from an rom-module in a cartridge slot. Another thing is : data that has to be accessed a lot should be in the internal ram of the turbo-R. Not only because of the slot-switching, but because of the access time too!

Re: Terminal Programs...
Sony RS232, Sunrise RS232, they can all reach 115k2. I think AccNet can too. It's not about the hardware, it's the software which limits the speed on those. Erix can reach those speeds, other terminal-programs can't (afaik). This is not true... The Sony RS232C can do all normal speeds until 19200 baud, but 38400 baud is not possible. With a little trick you can do 57600 baud. The problem is with the baud rate generator. 1.8432 Mhz / 2 / 16 = 57600 1.8432 Mhz / 6 / 16 = 19200 The first number is the oscilator frequency, the second number the clock divisor, and the last one is an internal divisor, required to be able to synchronise with the serial stream. (can be set to one, then you can send data at a very high rate, only receiving isn't possible in the ansynchrone mode) Since the duty cycle of the clock signal to the 8251 has to be 50% an odd number for the clock divisor is not allowed. But what I try to tell with this nonsense is that the capabilities of a RS232C interface are not only limited by the software. The hardware is one of the biggest problems.

Re: 64K VRAM? / DMA
I would expect the hardware to use the busreq-pin on the z80. But is that one actually in the cartridge-slot? Unfortunatly, no, it isn't... :-( It might be possible to add it to the MSX slot's, there are some reserved pins. However, just adding a wire from the ^BUSRQ signal to one of these pins isn't enough... It is relatively simple to control the direction of the databus. By means of busdir. But all the one-direction address drivers have to be replaced by bi-directional ones. If someone really makes a new MSX, DMA would be one of the things I would like to see. Now I come to another thing, on the R800, there seem to be some DMA control lines. Anyone knows how to use these? There are also 6 (?) interrupt pins, how does this work? And on the S1990, there are pins for high density select/detection (I am at university now, so I don't have the turbo-R manual here) Anyone knows on what registers these signals are located?

Drivers 1.44MB uses 360 r.p.m. when 720kb uses 300 r.p.m. ? So if you want to create 1.44MB drives for MSX, you either have to use 7MHz Z80 or use some kind of buffer for reading sectors. Are you sure? A 720kb disk works with a FDC that handles 250kbits/s, a 1440kb disk works with a FDC that handles 500kbits/s. I don't know, but if angular speed is 360 * 2 * PI / 60 , that required more CPU speed OR _DMA_ for flow control. This means that the main routine should be able to read 12500 bytes per turn. It means that this routine should run 12500 times in 0.2 seconds. Then, the routine should spend a maximum of 16 microseconds. In a 3.57561149MHz, this means 57 clockcicles.

What's this??? X-D A MSX Mailing List or a 'sketch' for a chapter of Sesame Street??? X- (Who the heck is going to sing us the song of 4? X- ) Just with the relation of floors... I have heard some rumours that in some large buildings the 13'th floor doesn't exist! So, we should start counting at 1, we should stop counting at 12 and continue counting with 14 But I don't think this counting should be standarized or so, it's not that important. Some programs are better implemented when counting starts at 0, and some like to start with 1. Please, end this discussion;-) Greetings from Erik Maas p.s.1 About the year 2000 problem I received a message from a friend, sorry it is in dutch only p.s.2 Please do not send any reaction to the mailinglist about this message [ Dutch mode on Please???] Wij zijn bezig met enkele personen om een nieuwe jaartelling cq. tijdsindicatie te genereren. Deze zou moeten worden ingevoerd op de overgang van 1999 naar 2000. Deze overgang wordt gezien als de eeuwwisseling maar is dat eigenlijk niet. Het jaar 0 bestaat namelijk niet in onze jaartelling dus de eeuwwisseling is eigenlijk van 2000 naar 2001. Dan is dit niet eens op de overgang van 31 december naar 1 januari, dit omdat sommige geleerden een rekenfout hebben gemaakt bij de invoering van de jaartelling, dit heeft men proberen te corrigeren door een eeuw of wat geleden een paar weken over te slaan. Deze correctie berekening is ook fout gelopen. Dus: op 2000 is het GEEN 2000 jaar geleden dat de oorsprong van onze jaartelling plaatsvond. Ook het aantal maanden in onze jaren kloppen niet, December de 10de maand genaamd is onze 12de maand, dit komt omdat de keizers Julius en Augustus hun maanden hebben toegevoegd aan de kalender. Tevens zitten we met onze klok, die afstamt uit een 60 tallig rekenstelsel, terwijl wij allen tegewoordig een tientallig stelsel gebruiken. Al met al klopt er dus niets van. Daarom willen wij tot een nieuw stelsel komen, er zijn al enkele voorstellen, een definitieve uitgave moet er nog komen, alle op en aanmerkingen zijn welkom: 1) Het moet een decimale tijds telling worden. 2) We gaan uit van de dagen die we opdelen in eenheden. 3) Jaren worden anders gedefinieerd, Waarom 364 dagen in een jaar en af en toe anders, laten we 1000 dagen in een jaar nemen. 4) Het begin van de telling wordt wat wij nu noemen 1 Jan. 2000 we noemen het dan de tijd voor/na de "Big Crash", hierdoor kunnen we de afkorting BC toch blijven gebruiken. 5) De tijdstelling cq. jaartelling wordt logaritmisch, het gehoor is immer ook zo, ons gevoel voor tijd zal dus ook logaritmisch verlopen. VB: naarmate we ouder worden lijkt de tijd te vliegen dit kunnen we dus opvangen met een andere schaalverdeling. 6) Door een logaritmische verdeling zijn we ook van het jaar 0 probleem af, deze bestaat dan gewoon niet. Een en ander wordt nog onderzocht, een ding staat vast: de programmeurs die het milennium probleem oplossen zijn hier niet blij mee, kunnen ze weer opnieuw beginnen. Eigenlijk zijn de programmeurs iets aan het oplossen wat niet bestaat, het milennium probleem, de overgang van 2000 naar 2001, bestaat niet. Gelukkig hebben we ook programmeurs die het jaar 2000 probleem oplossen. Ideen voor een nieuwe telling zijn van harte welkom, Arno en zijn belgium collega's. MSX Mailinglist.

Re: New Flash Complex Algorithms
My remark "New Flash == Slow RAM" isn't about internal technology, but only to suggest that Flash can be as easy to use as SRAM for nonvolatile storage. My point is that "complex" algorithms aren't needed for all Flash devices. Simple deblocking routines can make the page-mode transparent to applications, and make use of Flash burst-mode transfers. Flash does have the drawback of slower writes, and a limited lifetime of write-cycles. There is also a advantage when using Flash memory instead of S-RAM. Flash memory doesn't use external components to keep the contents when you turn off you computer. About the limited lifetime : I don't think this is very bad at all... How many writes are done under normal conditions in one year??? A game : let's say 1000??? (for savegames only) Settings for some programs : 30 times in a year??? H What was the subject that resulted into these Flash memory topics??? Greetings from Erik Maas p.s. At the time I only know one released project that uses normal Flash memory (29F???) and that's an IDE interface from Sunrise Swiss. Very nice for a software updates... At the time it was released, the software contained a lot of 'undocumented features' (bugs). I wonder if the software is mature now, still haven't tried anything with it. MSX Mailinglist.

Re: New product
Hello Erik, Can you tell me if it is possible to use very fast modems with this 232 interface. Specify very fast... 33k6 works, at least there are people using it. I use CACIS program but sometimes it is very difficult to use all Internet services, I will like to know more about ERIX program. Thanks in advance. When I connect to my PC localy, 115200 baud is not a problem. The hardware handshaking makes sure the buffer doesn't get full. (controlled by software) I have to confess 115200 baud works better on a turbo-R, that means : it can handle the data much faster. But a 3.58 Mzh Z80 can do it too, although not fast. You see that RTS will be more inactive then. I don't really know how good Erix will handle the internet services you are using. Cursor keys can emulate MSX, VT-52, ANSI and PC. (Cursor key codes when using the default settings in Telix). This is the data the MSX sends. Colour ANSI is also supported. Ah!, do you know who can repair my Novaxis interface?, but not Arjan Prosman, he sent me back my interface again broken. Regards. ALBERTO As far as I have heard, the 33C93 isn't made anymore. There are newer versions, but they are not pin compatible. I "HAD" a SMD 33C93A on a PCB, but I have trown it away a week ago. I will see if it is still there.

Re: New Flash == Slow RAM
Again about the Flash memory... Quoting directly from the Atmel data book, re their AT29C256... "PROGRAM: The device is reprogrammed on a page basis. If a byte of data within a page is to be changed, data for the entire page must be loaded into the device. Any byte that is not loaded during the programming of its page will be erased to FFh. Once the bytes of a page are loaded into the device, they are simul- taneously programmed during the internal programming period. After the first data byte has been loaded into the device, successive bytes are entered in the same way, Each new byte to be programmed must have its high-to-low transition on /WE (or /CE) within 150us of the low-to-high transition of /WE (or /CE) of the preceding byte. If a low-to-high transition is not detected within 150us of the last low-to-high transition, the load period will end and the internal programming period will start. A6 to A14 specify the page address. The page address must be valid during each high-to-low transition of /WE (or /CE). A0 to A5 specify the byte address within the page. The bytes may be loaded in any order, sequential loading is not required." I have one question : After writing a byte into a specific location, is it possible to erase this single byte? This is because with the AMD flashes I use, you can use an erase to set all bits to '1' and you use the program to set certain bit's to '0'. As far as I know a write action does not set bit's from '0' to '1'. If this is the way I think it is (just like above), it is not RAM. I thought I have seen this 'problem' in the AMD devices (29F040, 512 kbyte, 8 bit). It could be the software I wrote at that time was not correct. (Used it in a Gameboy cartridge with Flash memory. I programmed this cartridge with an adapter I made on my MSX) Greetings from Erik Maas MSX Mailinglist.

RE: New product
About the not-compatibility with Philips. Erik is right again.
Philips chose to make a rather different RS232.
Since it seems it was the most sold at Holland, it can be
regarded THERE as a standard. At Spain, France, Japan, Brazil
and so on, it is a nonentity.
For example, the most sold models were the SVI, Sony and the
spare boards I got a lot of years ago from Mitsubishi's MLG3.
Is Erik's RS compatible with Sony, SVI, Mitsubishi... in short,
with the ASCII/Micro$oft standards? Yes? Then it is a real
RS232C. End of arguing.
Sorry, I have to confess my RS232C doesn't comply with the MSX standard.
What I was trying to say is that the Philips RS232C interfaces don't comply
to this standard either...

RE: Turbo R?
External, it seems to work at 7 Mhz... But I guess if you measure a 7.12 Mhz Z80H, it seems to work at less than 2 Mhz externally... This is because the Von Neumann cycle and because the Z80 has no internal instruction FIFO. So, per opcode cycle it takes four clock cycles. This is just an idea I have about it, I haven't measured it yet... I don't have a memory scope or a logic analyser at home. And the scope I have is from 1966 and doesn't go beyond the 2 Mhz... :-( At least I got it for free!!! Conclusion : The clock circuit at the Xin and Xout of the R800 works at 28 Mhz, and can work at 40 Mhz. This does not say that the clock is or is not divided with four in the R800.

RE: Color Burst (was: A question about the PSG samples)
Here are some idea's about the color burst : As far as I know you can adjust the color burst phase with it. (Carrier that is send for a small time during horizontal sync to be able to demodulate the color information) If you have a RGB connection to your monitor, this would have no meaning. If a CVBS or RF connection is used, it COULD result in losing or disturbing the color information on your TV... (no damage) Probably it is only usefull for measuring purposes. (see if the PLL in the TV can lock to the color burst signal) At least for RGB this register doesn't make any sense. The times I tested this I hadn't studied electronics, so I didn't knew what to look for. I only used a RGB monitor. With a RGB monitor the color signal is directly on the RGB pins and not modulated in the video signal. If I have some time, I will measure it... Although, it's probably not very usefull.

RE: Looking for Ram (turbo-R with S1990)
Hello Egor, Probably there are no pull-ups inside the engine, but I think there is a design error that outputs 8 bits on the databus when the mapper register is read. This while the internal mapper register of the engine is probably 5 bits. So, when the mapper register of the engine is read, it drives bit 7..5 high. And yes, it is possible to make pull-ups inside a chip, I can't tell you now how this is done, I have too look it up in some old school-books... Now to the point with an external mapper, all the higher bits are read as one : e.g. Internal 512 Kbyte mapper External 2048 Kbyte mapper out hfe,1 in hfe - b1111 This is with and without the external mapper! I could be wrong, but I think with a 256 kbyte turbo-R ST even bit 4 will be high. By adding a pull-up to a certain pin, the engine can be configured at power-up. The engine wins the battle of the higher datalines because in series with the datalines from the processor(s) to the cartridge connectors there are resistors. (I think they are 100 ohm) The engine doesn't have these resistors in it's way to the processor(s).

Sounds VERY interesting. external large mapper will be pulled up. In theory this can damage both the external mapper and the S1990. I don't think that Panasonic will produce a new version of the S1990 to solve that problem. I don't think that Panasonic will produce anything anymore for MSX. So we will have to live with these problems and work around them with software routines! Whether we like it or not :-( I use a self made upgrade using a 1MB SIMM 80ns (30 pins PC DRAM) and some 74HCxx chips to enable read and write to the 'missing' 3 upper bit of the mapper registers, and I haven't destroy my S1990 until now. And this seems to prove my theory about S1990 actualy NOT outputting higher mapperbits. It seem that you have the some data about the internal structure of the S1990.

RE: GFX9000
I have some doubts about GFX9000:
1) Are they still produced?
Yes
2) How much does it cost?
NLG 390,- at the MSX fair in Tilburg. I think this is a special Tilburg price.
3) Can I connect it to my Expert? (brazilian MSX 1)
Probably, but I think you have to write your own programs, since almost all
programs available for it use MSX-DOS2. Since MSX-DOS2 requires a memory
mapper and an MSX2, this will not work...
4) Is there any graphic editor for SCREEN 2-4?
H...
Yes there are : eddy2, eh... I didn't really use these programs for MSX1
(right, screen 4 is for MSX2, but it's like screen 2, but with better sprites)
I'm not sure I did understand this question, you mean the screens of the V9938?
For the Gfx9000 the screen modes are named different.
5) Can I connect two GFX9000 on the same computer and get
four parallax scroll planes?
Then you will have to buy a Video 9000 with gennlock capabilities, otherwise
it is possible but with a very poor quality.
6) Are the VDP hardware-copy commands available in modes 2-4?
For V9938 : Not following the standard, but it should be possible, even in screen 0.
I have never done it. Some years ago (3??) I tried it but I didn't get it right.
But don't espect this will be very usefull.
7) Does it have superimposing capabilities?
Gfx9000 : yes, but very poor. It doesn't sync rights. At my computer there is more than
one pixel timing error. If the error would be constant, this would work, but it isn't.
Not
very useful...
Video9000 : yes, this is just as it suppose to be.
The advantage of the Video9000 are the digitizing capabilities. This is not available
in
the Gfx9000
8) In modes 2-4, how many bits has the DAC? (the palette can be selected
from how many colors?)
There are three DAC's. (Red, Green, Blue).
They are all five bits wide.
You can select from 32768 colors.

RE: MSX2+ Schemes Available...
1) Does anybody want the "unfitting" version (it may be useful while a new version is not ready)? I am interesed, even if it does not 'fit'. I try to collect as much information especially on hardware about MSX because I don't want it to get lost. I once had the MSX turbo-R datapack, but I have sold it two years ago. Now I hate I have done this. 2) Is there any freeware to generate vector+text files, so I can command "DELTREE WINWORD" from my 486? H... You mean another kind of word processor??? Especially for technical documentation or something like it? I have an illegal version of Acrobat Editor laying somewhere... It's not freeware for sure, but if you are interesed in this package, I can sent it to you. It's a Windows 3.1 version. I don't know the size, but it's not as large as the recent packages. But I wouldn't trow Word away, it's one of the packages I like because it's one of the best and simple to use package. Allthough it's from Microsoft. Greetings from Erik Maas application/ms-tnef
Re: Hnostar Magazine 41
Did you ever consider the fact that there are people who use their work or universitie to get Net-connection. When mail is so important to you, then why don't you have a private acount? Waarschijnlijk gaat het er hem niet om dat hij zijn mail zo belangrijk vind. Het probleem is dat er vrijdagavond even een berichtje komt waarin een deadline staat van de aankomende maandag. Toch net iets te krap voor velen. Om dit uit de weg te gaan hadden ze eigenlijk twee opties : - Eerder sturen - Latere deadline (sorry for saying it, but I just had to do it...) Idem... ;-) Ik heb trouwen ook thuis E-Mail en op het werk. Maar bij mij gaan er genoeg weekenden voorbij dat ik mijn mail niet lees. Op het werkt ben ik wel de hele tijd berijkbaar. Er verschijn een enveloppe rechtsonder als er mail binnenkomt. Groeten, Erik Maas p.s. Nog toevallig IETS gedaan aan je MSX Ik weinig, alleen maar even voor m'n RS232C interface.

RE: Looking for Ram (turbo-R with S1990)
You can configure the S1990 by placing a pull-up at a certain pin. If you put an extra 256 kbyte in your ST to make it 512 kbyte, you have to add this pull-up to configure the S1990 for 512 kbyte. I have done this with my ST too!!! The reason of this difference in number of bits that are driven high is this configuration. BUT, I don't know for sure of this problem exists with 256 kbyte. Someone could check this.

It's the same S1990 IC, so why should there be a difference in the number of bits that are fixed high? Also, Mark Zellenrath (do you still read this list?) has 512K internally in his ST and has never complained about software that stopped working after the memory expansion.

RE: Looking for Ram (turbo-R with S1990)
Hello Egor, The external mapper I use DOES support read-back. In a MSX2 it works just fine... Even with more than one mapper... And as a result of the problems in a turbo-R, more people have found out that there is a problem with mapper readback of the S1990... And it seemed to be that the origin of this problem is the one that's mentioned several times on this list. Greetings from Erik Maas -- From: Egor Voznessenski Sent: Wednesday, May 27, 1998 2:27 PM To: [EMAIL PROTECTED] Subject:Re: Looking for Ram (turbo-R with S1990) Now to the point with an external mapper, all the higher bits are read as one : e.g. Internal 512 Kbyte mapper External 2048 Kbyte mapper out hfe,1 in hfe - b1111 This is with and without the external mapper! I could be wrong, but I think with a 256 kbyte turbo-R ST even bit 4 will be high. By adding a pull-up to a certain pin, the engine can be configured at power-up. The point here is:Does this external mapper support read-back? As far as I understand many of the extensions don't support reading of their mappers (for example AddRam, if the circuit diagram of it that I found on the Net is correct) The engine wins the battle of the higher datalines because in series with the datalines from the processor(s) to the cartridge connectors there are resistors. (I think they are 100 ohm) Probably you are right here. (however 100 ohms seems a slightly bigger value than usual 22 or 33 ohms) application/ms-tnef
