Hi all, on Usenet I have found someone, Dave Gastelow, who was willing to help out in reading the CBM DOS1 ROM codes, esp. including the FDC disk controller code that is not yet in the archive. In this process we found that the read6530.lst from the archive (firmware/drives/old) does not work for DOS1 drives. So I rewrote it to read the DOS1 drives as well. Unfortunately Dave got a problem with his hardware, so we still only have an "approximate" readout :-( So I would like to ask anyone with a 2040 or 3040 disk drive to check out their DOS version (Any DOS1 with 670 blocks free on a freshly formatted disk is of interest here), and if it is not in the archive (esp. the FDC) http://www.zimmers.net/anonftp/pub/cbm/firmware/drives/old/4040 check out the programs I put on http://www.rzuser.uni-heidelberg.de/~fs1/dos1 (in binary and as listing), and upload the ROMs to the archive or send them to me (with IC codes if possible please). The "readfdc7" is to read the FDC ROM from a drive on unit 9 and write it to drive 8. It does a seek on the drive, but does not write anything and needs no disk. During the run, the disk drive from which the ROM is read must be reset. The "readdos" reads the upper 16k of the DOS address range ($c000- $ffff) and write it to a file. It asks for the disk units and filename. Both programs work on a Basic4 PET with a SFD1001, and run in a Basic2 (3032 PET) with a DOS1 disk, although you probably want to remove the first printout of the disk status. Then we can finally put this issue of the missing ROM to rest :-) Thanks in advance! André Message was sent through the cbm-hackers mailing list
