Hello Mike,

I have some working 1.44 floppy drives and disks that you can have. Also
still have some old IDE cards and cables if needed.

Give me a call to arrange.

Kind Regards,
Rob

There's one potential issue to be aware of when using old floppy drives that
have been sitting around unused for a longer time pretty much anywhere in NZ
(except maybe Central Otago): due to our healthy salty sea air the heads can
rust, and the rust then destroys the medium... a visual inspection of the
medium will shows this as circular scratches. 
(Don't ask how I come to know this...)

However, floppy is not the only option. The HD may still mount in computers
with old PATA controller. Alternatively, seeing the small size of only 40
MB, transfer via some sort of cable should also work. The gold standard from
back then would be 10 Mbaud Ethernet over 50 ohm coax cable, but failing
that, a PLIP / laplink cable would work, or even a null modem between the
UARTs of the old and new computer.

The advantage of the cable-based approaches obviously is that you don't copy
onto a fairly flaky medium like floppy in the first place. But then again,
if you run some effective hash sum on the old PC, and then again on the
system you are ultimately copying the data to, the error risks are obviously
perfectly manageable.

Kind regards,

Helmut.
