Hi Eric,
I have working 10MB and 20MB units here being driven by a PC XT with the
Iomega specific card for them.
I've had to puts lots of effort into cleaning the heads on them. I'm not
sure if there is an oxide shedding problem or just 30 years of dust that
I'm fighting, but they do seem to be very finicky at this stage. It also
could be a media formatting problem; I think they have servo tracks that
were laid down at manufacturing time, so if you have a read error on the
servo track there is no way to fix it.

I've got a collection of 1/2 height 8" drives, and one among them (a 20
MB unit) is able to come online with a cartridge inserted. Maybe head
cleaning is what is troubling the others - but I have no idea how I'd
jam a cotton swab in there and find the heads to attempt a cleaning.
I have a Bernoulli card in a PC that will lift the bits from
DOS-formatted cartridges, and I hook the drive up to an old Mac with a
SCSI card in it to image other arbitrary types (I've seen them used as
audio recording devices as well as external storage for HP equipment).
