Yes, I have compared the ROM provided with Virtual T and my own ROM and effectively, she are differents. Like I say to Steve, I wonder if, maybe, I can burn the VIRTUAL T M102 ROM inside a 27C256 to make a try ? Naturally, there is a risk of hardware incompatibility, so, this is maybe not a good idea.
This is very strange that Microsoft did an another version of ROM for the European version.

Already compared. So, maybe that EU ROM is not really compatible with TS-DOS.

The first byte I found that was different is at 0395h. I'll see what else I can find.

Neither one hung the emulator. Is the ROM image for your machine available? I'd be happy to test it.

The REX# run fine but I encouter a strange problem when I activate the resident portion of TS-DOS in RAM. In fact, when I edit a .DO file in TEXT editor and try to save him with the F3 button and a file name like for example: 0:test the TEXT editor crash and I must reset the machine. When the crash appears, sometime the screen freeze and sometime, a portion of code of TELCOM seems to be read because the menu PREV UP DOWN FULL of TELCOM appears on the bottom of the screen. An another more radical crash occur when you made the following procedure : 1° activate TS-DOS resident portion 2° in BASIC, run the command SOUND 400, 100 3° exit BASIC with the MENU command (or F8) 3° in TEXT editor, inpur some text and hit F3 4° input 0:test => now, all the screen disappears and the reset button don’t work; I need to power off and on the machine to restart. With the help of Steve, I tested an image of my ROM into VIRTUAL T and the issue can be reproduced. So, I wish to ask you if maybe, an owner of a Model 102 know this problem or if maybe, it is possible that my ROM image was incompatible with the version 4 or 4.1 of TS-DOS ? Thank you, Jean – Pierre
