I have a Seagate ST-225 that I want to put into my Micro PDP-11/73. At the
moment I am just trying to see if the disk works at all and if I can format
it in a MicroVAX 2000. It spins up but the TEST 70 and TEST 71 commands fail
on it, unable to determine the type of disk. There are some jumpers for
which I have found some documentation here:
http://stason.org/TULARC/pc/hard-drives-hdd/seagate/ST225-21MB-5-25-HH-MFM-S
T412.html, but I am not sure which is pin 1, and I am not sure what settings
the MicroVAX 2000 wants, or if it needs the resistor termination pack.
Can anyone tell me which jumper settings I need for the disk to work in a
2000? And whether I need the resistor pack installed?
Thanks
Rob
