Around 1982-1984, a company known as AVOS, Inc. modified first the Osborne I and then the Telcon Zorba for screen-reading via speech synthesis for use by the blind. At one time, there was an AVOS Blind User's Group. I am certain it no longer exists since AVOS went under years ago. If any modified Zorba users (besides myself, of course) read this newsgroup, I've got questions for them: (1) has anyone else encountered incorrect disk transfers with AVOS BACKUP program, written by Donald Krantz? I have encountered files with altered CRCs (from CRCK) in the middle of a transferred disk (specifically, M80.COM). My copies of BACKUP have a CRCK44 generated CRC of 886E. (I'm now using CFU from CPYFSTU.LBR plus SGEN/SYSGEN for the system). (2) Does anyone have the source to AVOS' Zorba terminal program STERM.COM? I'd like to see how they did their comm I/O and I might be persuaded to upgrade it to handle XMODEM-CRC, XMODEM-1K and True Ymodem protocols. BTW, I now have a modified BIOS that doesn't destroy the index registers X and Y. Thanks in advance. -- Mike Freeman K7UIJ -- P.S. CFU works fine.
