I often wondered why they did that. DEC had been making double-sided PCBs
for years before the VT50 seires, and I can't believe fitting all those
links was cost-effective.
Incidentally, the graphics board i na VT55 is a fibreglass PCB. At least
double sided, may well have internal power and groudn planes.
PCB.
(Phenolic?)
Did the VT5x have a microprocessor or was it discrete logic?
