the issue isn't with the converter, although the FTDI seems to work in some cases where the others don't, nor is it TEENY.CO once it's installed. The snag is with the TEENY.EXE install program; it's a DOS program and a PC old enough to run it natively (or even a new system temporarily booted into DOS) will probably not have USB<>com drivers whereas a newer USB-aware system likely will not run TEENY.EXE natively, and running it in something like DOSBOX seems to have mixed results. Re the old/new M100 issue: the main difference is the type of system ROM chip used; this matters if you want to update it, i.e. to replace the 19xx year with 20xx, fix a known obscure calculation error, add the Pi symbol, or just replace the Microsoft copyright notice with your name ;-). In the versions newer than the fall of '83 this is a straightforward plug-in replacement; the older systems would need an adapter. See "WhatVersionM100.pdf" and "m100y2k.pdf" in Steve's folder: http://www.club100.org/memfiles/index.php?PHPSESSID=20rhrake2sunpo4c45jhtnbhi2&direction=0&order=&directory=Steve%20Adolph It is also possible to put TS-DOS into the same ROM chip, essentially integrating it into the system firmware at the cost of making the option ROM slot unavailable for other software; this also depends on the ROM type. m ----- Original Message ----- From: "Jim Anderson" <[email protected]> To: <[email protected]> Sent: Tuesday, September 19, 2017 3:29 AM Subject: Re: [M100] Questions regarding REX and file transfer >> -----Original Message----- >> >> That'd be my first choice to get started if we're dealing with a PC with >> a real com port; I think a USB<>RS232 converter would probably be a >> problem. > > I've been using a USB RS232 device fairly regularly with TS-DOS without any > issues.
