Re: [M100] Ultimate Rom II TS-Dos
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. I don't know much about it, but it seems to me you are not far from re-creating it. Kurt On Wed, Mar 11, 2020, at 1:32 PM, Brian K.

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] 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#.

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.

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).

The attached file will generate TSLOAD. Quite a small Basic program that loads the file into memory, the .do file can be deleted after loading.

I don't have TS-Load but here is a DO file that will load it into ram. It's large, but once loaded you can delete the DO file and TS-DOS will be in RAM ready to use. This is one of the three loaders I put together for mComm.

You need DOS100.CO which is about 6k in size.
