I have tried hooking a Tandon TM-100 to my ST with some success, although I haven't played with it much lately. Here's a brief synopsis of what I did: 1. Trash the 300 ohm terminator and replace it with a 1K ohm part. The 300 ohm pull up is too much for the low current driver in the ST. Also look out for soldered-in 300 ohm resistors on the drive logic; take your handy VOM or DVM and check between the +5v pin on the power connector and the even pins on the edge connector on the drive. 2. Make sure you have the drive jumpered as a drive 0. The ST daisy-chains the select lines so every drive in line needs to be "drive 0". This was 90% of my troubles. The other 10% were evenly divided between not having a proper format utility, and not having the correct info to slow the seek rate. I got around the former problem by formatting on a handy PC/AT, and the latter by ignoring it (for the purposes of experimenting; I don't run the Tandon much at all). Both missing pieces are in the public domain, to the best of my knowledge. There are PD format utilities, and not too long ago I saw someone discussing the correct memory locations to change to slow down the seek rate. Hope all this helps. Good luck! -- Farrell

I'd like that information too. Thanks. ---Mike Dunn, Indiana University ARPA: dunn@silver.bacs.indiana.edu UUCP: ...iuvax!silver!dunn CSNET: dunn@Indiana BITNET: dunn@iubacs
