So it's not too heavy. Me being set in my ways should in no way reflect on your toolchain choices. It's a great piece of software that has given me no trouble, even in my peculiar configuration. LaddieAlpha has enabled me to have a 32K computer with 40 terabytes of addressable directly attached storage, and it is a glorious thing for which I am grateful. I just happen to like to keep the environment on the host trimmed to the bone so it's easily replaceable, and to contain as much single purpose stuff as possible in tidy little packages like containers so they're easy to move around if I need to.
[M100] Proud owner of a TRS-80 Model 100
Hi all! Thanks to Jim Craven (jimcrav...@gmail.com) today I became the proud owner of a Model T! Pictures here! https://imgur.com/gallery/m3lkR3s I can't wait to run CP/M on it! I have two main questions for the community, although I have asked one before: 1) How necessary is it to replace the internal NiCd battery? My battery is not leaking but it has a tiny bit of corrosion on one side. Take a look here: https://photos.app.goo.gl/c9Bs7eSUc3NMtc6f8 It looks like ArcadeShopper carries replacement batteries. Is a NiCd or NiMH replacement better? If necessary, how hard is removal/replacement? I don't want to damage any traces! 2) Which would be a better ROM addition - the REX or REXCPM? I have asked before, but I'm just (nagging) curious how soon the REXCPM will be ready. Would either of these ROMs be compatible with 80x10 or 60x10 screen enhancements? Stay safe from CoVID-19! Thanks, Jon
Re: [M100] REX on M200
REX hardware and CPLD load is the same between 100 and 200 but the flash load is different. Flash load can be changed in the 200 in-situ -- just follow the REX flash upgrade procedure.

That looks great Brian. Back in the day there was a device called RAMBO which was an option RAM which could be loaded by the machine with any ROM image.

Re: [M100] Dockerized TPDD access to storage server
I think I just apt-get install mono-complete or something like that. Even old moldy versions work because it was designed for compatibility with .net 2.0 originally. The reason I chose c# is it gives me full portability across windows, osx and Linux. And I confirmed it even runs on a raspberry pi. So it's not too heavy. At some point I'll confirm it working on dotnet core instead of mono. -- John.
Re: [M100] Dockerized TPDD access to storage server
That's a good idea... I use a NUC as a storage server. I will set up a LaddieAlpha instance on the NUC. Between the cable on the USB serial interface and the 6 foot null modem cable I've got (Fry's had a female DB25 to male DE9 null modem cable. Handy.), I have like 18 feet of cord... that will reach anywhere in my room I'm likely to use my machines.

Re: [M100] Ultimate Rom II TS-Dos
machine has my REX in it because it's far easier to test ROM images with REX than to burn them to a ROM. As an in-between level of fanciness, I just finished making a little board that puts a 28C256 in a 27C256 socket. That could be used in the option rom socket of an 8201 or 8300, and the system rom in 8201 but not 8300. It still requires an eprom programmer, but at least you don't need a UV eraser and 20 minutes just to program the chip. No test clip either. You just stick the chip in the programmer and flash it. And it works like a plain rom, no possible compatibility issues. https://oshpark.com/shared_projects/pYmaUMlK And I'm waiting to test a PC-8300 system rom board. 8300 has an unusual 1Mbit main rom, not 27C256, and not even 27C1000, but it's at least pretty close to 27C1000, so it only takes a single jumper and a couple pullup resistors to make the pinout switchable between the 8300 special pinout and a pinout a programmer recognizes for the flash chip on the board, so it too is programmable right in a programmer zif socket with no uv or test clip. Well I made one version that needs 2 jumpers and 3 dupont wires to program it, and another version that needs no wires and only a single jumper. I haven't made up my mind but I think I actually like the more complicated one better for the admittedly dumb reason that it fits entirely in the ROM0 DIP-28 socket, while the simpler and more practical one is 32-pins, so it has 4 extra pins that hang off one end of the socket. Works fine, doesn't hurt anything, easier for a user to get it right.

Re: [M100] REX on M200
Yes just needs to be re-flashed and it should be fine. It is probably the easiest way to get TS-DOS onto the machine.

I was expecting some sort of additional RAM disk, since CP/M really needs the full 64K for doing its own thing (and CP/M 3 could use banking to get a lot more than 64K of RAM of course, by that point, DOS was the new king, and CP/M was already on its way to the grave.)

I have about 6, a few with the 64k multiunit for the RAM driver. I have a dual-serial Rpi that provides 4 floppies using Vfloppy and a serial console on the other port. I need to start selling some!

Re: [M100] REX3?
This is from an earlier reply about the present state of the hardware. I've got a T102 with a regular REX so I used this as an excuse to pick up a M100 that I'm in the process of refurbishing as soon as the parts come in. In M100 and T102, you need an additional board 1) in M100, the adapter plugs into the system bus and connects via a 3 wire cable to REXCPM. No soldering, plug and play. 2) in T102, the adapter plugs into the adjacent 8kRAM socket, and connects via a 3 wire cable to REXCPM. An additional wire needs to run to M37 Pin 11. I'm currently evaluating if a clip can be used or if it needs to be soldered. So, plug and play in M100. Still evaluating if it can be "solder free" in T102 using a clip. Both solutions need the adapter board. -- Original Message -- From: "Tom Wilson" To: "M100 Mailing List" Sent: 3/11/2020 3:47:58 PM Subject: Re: [M100] REX3? This has me curious...

Re: [M100] REX3?
REX2 was an original attempt at a module that supported CP/M. It did not survive! I think I made 6 of them total. Those 6 worked fine as a standard REX. With only 128k of RAM, it would have needed some pretty fancy software to turn a flash chip into a read/write disk drive. REXCPM takes a different approach - no flash, just a whopping big SRAM.

Re: [M100] Ultimate Rom II TS-Dos
Anyone on the list can reach out for REX. If I have some, great, or I build them. Given my big effort on REXCPM, I've spent some time on how to make REX easier and cheaper. That's REX#. Soon to be available. On Wed, Mar 11, 2020 at 1:52 PM Josh Malone wrote: > Gotcha! Thanks!

Re: [M100] Ultimate Rom II TS-Dos
A 27C512 has the identical pin configuration as a 27C256 with the exception of pin 1. Pin 1 is used to access the upper 32k or the ROM. On the system board, U11 is the chip of interest. Here is what happens when you go from bank 1 to 2 and to 3. 10 15 0 0 = Bank 1 0 1 = Bank 2 1 1 = Bank 3 If you tie pin 1 of the 27C512 to pin 15 of U11, then when you switch banks, you switch ROMs. I have two machines wired this way. My third machine has my REX in it because it's far easier to test ROM images with REX than to burn them to a ROM. Kurt On Wed, Mar 11, 2020, at 10:38 AM, Josh Malone wrote: > Details!

Re: [M100] Ultimate Rom II TS-Dos
Speaking of standard ROMS, a 27C512 can be burned with SARDOS on the lower 32k and UR-II on the upper 32k. Then pin one wired to a pin on the system board. This allows for bank 1 to have SARDOS and bank 2 to have UR-II. I have a couple of mine setup this way.

It is, I'd be happy to put one together. I just send out my last one in stock. I can get going on a build and get back to you? My kids are my new shipping department. Fun times.

Re: [M100] Ultimate Rom II TS-Dos
The 8201a can take a standard 27C256, so you can drop in a 'SARDOS' ROM or some such. If you want one, I can burn it for you (I might have 1 or 2 already made up from Tandy Assmebly).

Is there a loader for NEC TSDOS? My 8201A doesn't have an option rom, but I can transfer DO files to it from my M100.

Re: [M100] REX + Ultrascreen100
REX heavily uses ALTLCD.. that memory space is almost surely being clobbered by Ultrascreen. I didn't design REX with the though that Ultrascreen would need to be usable with it, in the same way DVI does not work with REX. Sorry! In my new project REX#, I may be able to address that.Also possible to address with REXCPM. Steve On Wed, Mar 11, 2020 at 12:10 PM Jason Benson wrote: > Can I call the Rexmanger from a BASIC program?
