1) The machine contains what I assume to be the hard

capacity/type of drives will the machine accept - and where can I get one?
Hard to tell without seeing the controller, or knowing what flat cables
are coming off it. IBM was quite fond of using a proprietary and
oddly-wired interface that, apparently, only IBM drives could plug into.
My advice would be to scare up an Adaptec 1640 or similar MCA SCSI adapter
and just use SCSI drives.
2) Can the machine accept 2.88Mb drives (this one is
purely out of interest)?
That will take a wiser head than mine to answer. I know the model 85's and
95's can, but I'm not sure about the older systems.
3) There is an expansion card with no markings on
installed in the slot
farthest away from the PSU. It is connected to what appears to be the
processor socket ('286 right?) by a section of flexible PCB.
Whoa! That sounds like an aftermarket CPU upgrade board. God only knows
who made it, though...
Was it fitted as standard or was it added later?
Had to be later. IBM never made such things available that I know of.
4) The "paddle" on the power switch has been
broken off. Can I get a
replacement switch or do I need to get a new PSU?
You can go either way. Want me to see if I can find you either one at the
local used computer place?
