Ooh! A Lilith. I lucked out and have 4 main units,
but I need docs,
and information on hooking up keyboards, mice and monitors. I think
the monitors are special for the Lilith. What did you get besides the
main unit?
Richard,
yours are Eves, the followup on the Lilith.
Keyboard, mice and monitors are indeed special to the Lilith.
The keyboard has a serial, straight ASCII output and goes to the
monitor. In the monitor is a serial to parallel convertor and the
keyboard data then goes in parallel to the main unit !
The mouse is a 3 key straight quadrature output thingie.
The (external) floppy is very particular: it has an Apple II floppy
controller card, a small 6502 motherboard in which the apple floppy unit
plugs and a serial connection .
The backplane has a 200 contact connector, the force required to insert
PCB is incredible.
My Lilih is once again playing up, I will have to bite the bullet and
draw the schematics. Cheap IC sockets might play a role, but
substituting a few hundred of them is also a PITA.
