Here is a method for transferring files from TOS to CP/M-emulator's disk. It is painful, but using this technique I moved several files including PIP, STAT, DDT, BDS C compiler, etc. I own all of these on an Osborne-1 that I rarely use now. This is being posted in a 'good spirit.' Don't send me or this group any flames on the legality of this. Enter CP/M emulator. Insert a TOS-formatted disk. This should contain no files (either TOS or CP/M). Now issue the CP/M command save 32 junk.ddd which saves 32 'pages' of CP/M core image as file junk.ddd. This ofcourse contains garbage, but never mind that. Now exit CP/M. Write a program to run on TOS to read a file (from a TOS disk) and wait until you change the disk to the above CP/M disk (with the junk.ddd file), and write the file out onto consecutive sectors whose logical numbers begin at 26. (Because we saved 32 pages (== 8k), make sure the file you are transferring is <= 8k. If you want to transfer larger files, change the 32 to whatever.) A SSDD TOS disk has 9 sectors (numbered 1 to 9) on each track (numbered 0 upwards). So logical sector number 26 (say, s) is track 2 (== s/9) phys sector 9 (== (s modulo 9) + 1). Each sector holds 512 bytes. I suggest that you transfer either a vanilla MODEM7.COM or PIP.COM this way. Now re-enter CP/M emulator, do a 'ren pip.com=junk.ddd' (assuming you transferred PIP). Type 'pip' and you should see the '*' as the prompt. Once PIP is working, you can copy files in a number of ways. The CP/M disk with files can be disk-copied with TOS (e.g. COPYDISK.PRG). -- prabhaker mateti decvax!cwruecmp!pm department of computer engineering & science pm@Case case western reserve university (pm%Case@csnet-relay) cleveland, oh 44106 (216) 368-2816

Some of us are a bit concerned about the CP/M-80 emulator that was
posted to the net lately. I don't have an Atari handy, but aparently
it has a Copyright notice and serial number. Was this actually public
domain? Does anyone know who the author is so I can check?
