There were also at least 3 different front panels : no drives, 2
horizontally-mounted full-height drives, and 2 vertically mounted 2/3rd
height drivwa.
Yep - plus front panels that say 380Z-FD rather than just 380Z, and of
course one that says Winchester Disk rather than 380Z. Plus it sounds
like there are at least five different rear case panels - two variants
with the same holes, one with two RGB-type holes, one with a horizontal
RGB-type hole, and the one for the Winchester unit.
Then there are white-cased and blue-cased machines on top of that.
Actually, I'd not heard of the blue-cased machines before. Maybe they're
in standard off-the-shelf instrument cases rather than with RML logos,
panel cut-outs etc.?
I don't know of anyone with anything other than a black-cased machine
(albeit there are a few variants out there) - shows how much RML
hardware and knowledge has been lost I suppose :-(
Oh, Xebec board in my fileserver is an S1410, for which I have a manual
and a couple of spare boards, so I can do some messing around with a PC
parallel port driver. There's even a sample Z80 interface schematic in
the back of the manual that's probably adaptable...
Still concerned about timings though as some of the timing diagrams do
have upper constraints on signal changes (a lot of them only specify a
minimum limit). Time will tell if the PC's port is quick enough...
