At the most recent CoCoFEST!, I brought home the old Glenside Club
Computer Hard Drive. The mechanism is an ST-251, and I was
wondering if
someone on-list would be willing to attempt to pull data off the
drive.
In my experience, reading the data from this type of drive is
dramatically simplified if
you have the original controller it was attached to. If you can get
your hands on it, this
job will be many many times easier, and doable without special equipment.

I did not know that.
I do have the original controller, but it's a bit complicated.
The controller is a Burke & Burke CoCo HDD controller. I pulled the PCB
from it. Inside is 2 PCBs. One looks like a standard 8 bit ISA card
(WD1002A-WX1, no rev number), and the other is a small PCB that appears
to adapt the ISA bus to the CoCo bus (4 MSI TTL and a CR2032 battery).
I assume just having the ISA card would be enough...
