My apologies then, should have checked the reference materials. The only
time I was "Face-2-Face" with a PDP-8/A was during a short stint at
Racal-Milgo in Miama (1980-1981). That one definately used semiconductor

The PDP8/A did not use a microprocessor. It was TTL SSI/MSI like the 8/E,
ia different design and packaged more densely. The 8/A replaced some random
with small ROMSs, and later models used semiconductor memory instead of
All subsequent models, e.g., vT78 and DecMate, were microprocessor-based.
