[comp.sys.amiga] DF1: hookup?

wendell@medsys.UUCP (bbs amiga user) (08/30/89)

Help! I recently bought a Toshiba Double Density 3.5 drive that came out of a 
junked PS/2. After getting a pinout of the 34-pin *standard* connector, and
the Amiga 23 (yuch) pin connector, I proceeded to hook the thing up. No go...
I get power and ground ok. The drive spins up (spinning in perfect unison with
drive 0 actually), and the activity led works (also in perfect unison with the
one on the internal drive). Now I know this sounds like it's jumpered as drive
zero, but it's not. It's jumpered as drive 1 (from 0,1,2,3). The Amiga
SEL_2 is wired to _SEL 1 on the drive (Amiga is numbered 1,2,3; drive is 0,1,2)
What I think might be part of the problem is that the Amiga manual says pin
9 is _SEL 0, and the Drive manual says it's Motor Enable 1, and what it says
is _MTRON is Motor Enable 2 in the Drive manual. (when I say Amiga manual,
I mean the schematic in the back of the Introduction to the Amiga 500, and
am talking about the internal 34-pin connector.) 
Other obvious discrepancies? are, the Amiga intro says pin 1 is _CHNG, and the
drive manual says it's Reduced Write. Also, the Amiga intro says pin 33 is _RDY
and the drive manual says it's Disk Change. Any and all help on this would
be greatly appreciated! Thanks in advance... Not knowing how much interest there
is in this sort of thing... Email me at the address below please...
