I believe all the third party RS232 cards copied the DSR ROMS from the TI version. It is available via anonymous ftp to star.acs.umn.edu. For anyone interested, I also have disassembled code for the TI disk controller card, the console ROMs (from a 99/4A), and the Mini Memory module. Lots of good information. If anyone has a problem getting them, send me some E-mail, and I can mail them to you. David Nieters University of Minnesota daven@vx.acs.umn.edu
