8 inch floppy notes

Using the CP/M FAQ I built a 34 to 50 pin converter. A couple of notes: 1) read the whole FAQ. The wiring instructions in Q14 don't take into account the IBM-PC "floppy twist". Q16 gives the wiring that worked for me. Spent an hour scratching my head on that before I read further. Primary indicative behavior: seeks with no head load, software reporting access attempts with no head load. 2) The Radio Shack General Purpose Component PC Board (Cat. No. 276-168B) makes a great platform to build the converter on. Took me about an hour to solder it up. 3) There seems to be a bug in 22DISK versions greater than 1.31. The directory read code does not seem to use the seek delay. Either that or it simply misses a head step. It always reports cylinder 2 read errors. Despite this, it can format, read and write just fine. It just can't display directories. Spent another two hours on that. BTW older versions of 22DISK can be found with FTP searches, sorry I don't remember where I got 1.31 (I downloaded 5 different versions from different sites). Bill Sudbrink
