The disk images in this directory were generated from a set of original distribution disks from a Visual 1050. The disks were taken directly from a sealed case and immediately imaged so these bits are the pristine copies of the disks. The labels on the disks are accurately imbedded in the IMD descriptions and summarized below. Although it is not clear from the label data below, the BIOS version is v1.3 which, in theory, includes winchester driver support. The disk format is 80 tracks, single sided, 10 sectors per track, 512 bytes per sector The following format definition can be used for cpmtools if you extract the .imd files into binary files using IMDU: diskdef v1050 seclen 512 tracks 80 sectrk 10 blocksize 2048 maxdir 128 skew 0 boottrk 2 os 3 end Wayne Warthen wwarthen@gmail.com === DRGRAPH.IMD === IMD 1.17: 3/09/2012 11:35:22 VISION 1050 DR Graph SN 5006-0768-1 VN 1.0 === CPMPLUS2.IMD === IMD 1.17: 3/09/2012 11:43:52 VISION 1050 CP/M Plus Additional Files SN CP2768-1 VN 3.0 === CPMPLUS1.IMD === IMD 1.17: 3/09/2012 11:40:57 VISION 1050 CP/M Plus SN CP2768-1 VN 3.0 === WORDSTAR.IMD === IMD 1.17: 3/09/2012 13:30:43 VISION 1050 Word Star with Mail Merge AHC571P9 === MULTIPLN.IMD === IMD 1.17: 3/09/2012 13:27:33 VISION 1050 Multiplan SN 12768 VN 1.05 === CBASIC.IMD === IMD 1.17: 3/09/2012 11:31:26 VISUAL 1050 CBASIC and Demonstration SN 3000-0768-1 VN 2.8
