Re: Out to #FC-#FF
Cache makes your drive much slower. My Sunrise IDE: w/o cache: 230 kbps w/ cache: 50 kbps How did you test this? By just testing disk I/O time? Yes. And you should have quoted (or at least read) the rest of my message too. Well then you probably don't understand caching: (I can hardly believe it, me explaining you something :-) ) I already know how cache works. Otherwise I wouldn't use it, don't you think? present in the cache - is needed again, cache is just a waste of time. Cache doesn't make I/O faster, but reduces the times the slowest I/O is needed. So in practice you will gain speed. How larger the memory used for cache, how higher the chance used data is present in the cache, so how faster disk acces becomes. I know, but as I said the gain in speed reading cached data is very small compared to when using non-cached data only. And the loss in speed when reading non-cached data is huge. Let me explain you something about how the Sunrise IDE-interface works (and I think the MegaSCSI also works this way). The interface uses a memory-mapped I/O system, hence it doesn't use any I/O ports, but memory addresses instead. It is designed in a very smart way, because the sector read from the drive is DIRECTLY loaded into a dedicated area of the IDE-interface its memory. The only thing which has to be done is using an LDIR to move it to the appropriate location. When caching the data (first time scenario), an additional LDIR is issued to move it to the cache-memory, so that makes 2 LDIR's per sector read, instead of one without cache. When reading cached data, it is LDIRed from the cache-memory, but when reading from disk also only one LDIR is used, so in that case there is no gain either (but also no loss). In theory there still is a small gain in the last scenario, because the cache can LDIR the cached data in larger chunks, and it doesn't have to wait for the harddisk (however you won't really notice it on MSX with new harddisks). But in practice, this gain is very little and absolutely NOT worth 50% of my 2MB mapper and the slow first-time loading. On my old BERT (I/O-based) SCSI-interface, the non-cached transfer rate was about 50kb/s. So on that one, caching really did make a difference. ~Grauw -- email me: [EMAIL PROTECTED] or ICQ: 10196372 visit my homepage at http://grauw.blehq.org/ MSX Mailinglist.

Re: Sony computer
Hello MSXers around the world. I am not an expert in the English language, but lets try. Last month I bought a Sony HB-F1XV MSX 2+ from a friend. Its my first japanese MSX and its has some bit differences from the others brazilian computers. IMHO its great! Ofcourse. First of all I would like to know if there are any manual of this computer around the Web, or if someone could sell me a copy of it. The major informations I need is about the Speed Controler and Ren-Sha Turbo sliders. Aren't they the same??? Well, my Sanyo MSX2+ has only one slider, and a pause button. With the slider you can regulate the autofire (influences the spacebar and joystick firebutton). The Pause key completely halts the computer. It's useful with puzzlegames of which the software-pausebutton scrambles up the screen, or with games which haven't got a pause-button at all. And ofcourse to see how certain things are being done. The organization of the memory Slots is wanted too. If you have any files related with F1XV please contact me. Pfff... Just run Compass (even the Beta will do), and see what it reports in the slot layout section. ~Grauw -- email me: [EMAIL PROTECTED] or ICQ: 10196372 visit my homepage at http://grauw.blehq.org/ MSX Mailinglist.

But when I was on holidays in Germany (last summer), I couldn't find any public internet access until we arrived in the large city Trier (and two days later we got home :)). So I actually think you're right, it depends per country (or rather: per area). But I don't really think it has something to do with economy or something like that... We weren't visiting a poor area of Germany, and my Uncle's town in Sweden isn't that rich (and everything is awfully expensive there). ~Grauw -- email me: [EMAIL PROTECTED] or ICQ: 10196372 visit my homepage at http://grauw.blehq.org/ MSX Mailinglist.

RE: Out to #FC-#FF
Hi, Ofcourse there is a huge performance loss instead of just copying the data to its final destination, which probably is just on step. You have to read and write all data a second time to be able to store it in the cache. The problem with the storage is that you also have to select the most ideal situation to be able to execute a simple LDIR to copy the data. And maybe some extra slotswitches and memory mapper switches through the proper channels if your working with DOS2. If there should be something that a caching mechanism should eliminate then it would be the seek times of a harddisk, that is if the seek times are a problem. How about optimizing the caching of the FAT and directory structures.

4kb contest.
Sp, June 29th 2000 Hello. Only to say that there is still only 1 week until the deadline for the 4KB MSX1 Game contest. ( it ends July 7th 2000 ) Several people says there is not time enough. As the main objetive is to get several MSX1 games, and the best quality possible, if you (who are programming a game for the contest) think, we can give an extra week for the contest. But all programmers must agree. Please, reply soon, if you need an extra week, or if you want to keep the current date of July 7th.

Re: Yamaha SFG-05
I have a few questions: I've read in the article on Alex his page that you need a extra cartridge to be able to access the fm module through it's build in MIDI ports, it's called the 'YRM-502 FM Voicing Program II' cartridge. Does someone has such a cartridge? Do I really need one? Has anyone got the keyboard that works with the module? How do I get sound out of it? Lot's of options in the menu's but I don't have the manual of this cartridge. Is someone willing to scan his manual? ;-) Sander, I think you don't need a voicing program cartridge. The midi playback is always enabled, at least with my CX5M which has an SFG-05 plugged in. I have the FM Voicing program (I), FM Music composer, FM Music macro cartridges of which I can make images if you would like to have them.
