I would like to hear from anyone who might have access to the source code for the set of programs used with the Teletek hard disk controller (HDC). After accepting my purchase order Teletek discovered that several of that product's components were missing. If I can find them somewhere, I am sure I will be able to arrange with Teletek to get a copy. About a year ago I enhanced my Teletek Systemaster-I CP/M system by adding a hard disk and the Teletek HDC. The purchase included COM files for HDLOAD (loads driver into BIOS), HDPATCH (patches parameter table in HDLOAD), and HDU (utility to park heads, verify disk, etc.). These were identified as being version B.10. In December I ordered the source code for these programs. The first diskette they sent me had a garbled directory. The second contained (1) version B.40101 of HDLOAD.ASM [an updated version, good enough], (2) version B.0 of HDPATCH.ASM [which predates my original programs and is incompatible with them], and (3) HDU.ASM [but with none of its subroutines]. Finally, Teletek admitted they can't find the source files for the missing modules. Incidentally, I got started on all this when I tried to install SUPRBDOS (the public domain replacement for DRI's BDOS) and discovered that the HDC driver trashes the IX register SUPRBDOS is using. I can easily modify the new HDLOAD to save and restore the IX register. And I might be able to install the parameter table manually. However, the new HDLOAD and the original HDU appear to be incompatible. I would appreciate whatever help anyone can give me.
