:)) We had this already. I was satisfied when I got my hands on
a turnover, back when the A2 was still my main machine and I had
to do some (turbo Pascal) programming for clients using IBM-PCs.

I was rather thinking about either using a 3 1/2 drive on an A2
to write GSOS disks (readable with older Macs), or better, using
an LC with the IIe card, and a 5 1/4 drive connected. From there
on it's a childs play to copy any A2/3 disk to the Mac side, and
from there onto the net or at least PC 3 1/2s.

only the newer ones. I don't know if he said anything about new
Macs. And, beside that, actual PCs are as 'solderning friendly'
as any Mac.
