Ken,
On my real 8201, I'm using the ROM that came with it, with a y2k mod. For
Virtual-T I'm using the one packaged with the install. They are different
though. I know this simply because I tried to use the Virtual-T image in my
real 8201 and it didn't work properly with Sardine. It did work fine with URII.
Usually when I get the OK prompt in Virtual-T, I find I've got the wrong
machine selected.
I'm using the HEX file from club100 but I've also used the 4.1 rom image I put
together with the Shift+Down bug fix. And I've also used the SARDOS image. All
three give the same results.
It's definitely a banking issue. I'll look into A1h a bit to see if it sheds
any light.

I can't even get the TS-DOS ROM to work properly in VirtualT. Each time I
initialize the ROM, it brings up the TS-DOS screen, but when I exit (Shift F5),
it just gives me an "Ok" prompt and then won't really do anything. I mean I
can type, etc. but there is basically no response except to always give an "Ok"
prompt, regardless of what I type in.
Plus within TS-DOS, if I hit F4 (Disk), I get "?BS Error in 10".
Perhaps my tsdosnec.hex file has some issue (though each line has a checksum on
it)? Or maybe my NEC main ROM has an issue.
I'm wondering if maybe the DOS-ON feature is not properly preserving the RAM
bank number when switching the ROM bank to the OptROM. Both of these bank
numbers are set using the same OUT A1h opcode.

I'll have to check in debug mode to see what's actually being sent but the
machine (and Virtual-T) locks on banks 2 and 3.

What happens on the wire? And I assume the BA file is tokenized?
Was the BA file generated by a previous SAVE by the same version of TS-DOS?
Is it a NEC BASIC file?
