I did some software work on a Horizon many years ago. As I recall, it had
two full height 5.25" bays, a good sized power supply behind the bays (on
the right side) and a shorty S-100 card cage on the left, 8 card slots? But
the NS motherboard also had some logic on the motherboard, at the rear. I
believe there were one or two 8251 serial ports, a baud rate generator,
maybe a parallel port or interrupt controller (look for an Intel 8214 or a
28-pin AMD IC)?
