Osborne OCC1

I made so more progress with my Osborne I project.

Initially, I had taken a few steps forward by integrating the working parts of
two
non-working systems into a single working system. Well it seems that when I
tried
to put it all
back together I managed to put a case screw right through the %_at_$# disk drive
ribbon
cable. Funny thing is is that the B drive worked but the A drive wouldn't boot
but would provide listings from 'dir' command. I immediately thought alignment
as the damn thing did clunk once upon reassembly. Well I discovered the cable
problem and put the other one in. Viola, fixed! Anyway, I do plan to document
this
process. I did discover that you can convert a working B drive into an A drive
if the A electronics is working. IOW, the mechanical parts of a Siemans 100
drive
are the same, it is the electronics board that makes an A drive an A and a B
drive
a B. What I have now drive-wise is a good set of A and B drives plus a spare A
drive and good B electronics board with a faulty drive mechanics portion. I
could
make the spare a B drive if need be (B!). Must be late. :)

A last ditch effort will be to try and fix the faulty drive's mechanical
portion. Either
way, I'm done tommorrow and will reassemeble the working system and put
the parts system back together as well. But I must first leave a trail to
follow
if ever me or anyone else picks up on these two systems in the future.
