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.

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
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.

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.

0 0 = Bank 1
0 1 = Bank 2
1 1 = Bank 3

Details! This sounds great. I didn't realize that REXNEC (or whatever it's
called) was still being built, so I haven't REXed up my NEC.

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.
On Wed, Mar 11, 2020, at 10:23 AM,
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). Contact me off-list

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.

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.

Thanks for this. For those of us with optionless hardware you wouldn't happen
to have the loader handy as well, would you? I think it's called TSLOAD? Ive
been keeping DOS100 itself in RAM and it's kind
TS-DOS and Sardine for UR-II attached

You need DOS100.CO which is about 6k in size. UR-II loads it from your TPDD
device (Original floppy disk, or emulator such as mComm, Laddiealpha or
Nadsbox) The Sardine spell checker can also be loaded in the same way.

When I try to run TS-DOS from the Ultimate ROM II(v2.12) I get the error
"Not found". Do I need to load a separate binary for TS-DOS? I haven't
found one yet , but I still have a lot of stuff to look through.
