I have two TEAC 55B drives from my previous computer, but neither of them will work in the AT, either as drive A or drive B. The drive which came with the system is a TEAC 55BV, which has completely different jumpers. I asked a friend who has a PC with TEAC drives for the jumper settings, and they were the same as I had them set (DS1, HM, IU, SM, and PM all shorted). I have traced the problem to the solenoid not pulling Head 0 to the disk surface when the motor is powered up (the 55BV does not have a solenoid, just a mechanical interlock that prevents Head 0 from moving all the way toward Head 1 when there is no disk in the drive). I never noticed the lack of the characteristic click on accessing the drive, since I had become so used to it that I didn't hear it anymore, and the 55BV has no click. Now my question: Has anyone out there used a TEAC 55B drive on an AT clone? If so, please let me know the jumper settings and any other pertinent info. MUCH Thanks in advance. +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=+ | ARPA: RALF@B.GP.CS.CMU.EDU "Teaching COBOL ought to be | | AT&T: (412) 268-3053 (school) regarded as a criminal act" | | Snail: Ralf Brown --- Edsger Dijkstra | | Computer Science Department | | Carnegie-Mellon University DISCLAIMER?
