I've been told the Imlac processor is based on the PDP-8, or that it has

programmed either.
Some info to this effect here:

It bears a striking resemblance to the core stack in an PDP-8/L or
PDP-8/i (those, of course, are either 4096x12 or 4096x13, depending on
parity. Even the fingers look like DEC spacing.
I am unfamiliar with the Imlac line... why would there be such
similarities? Dataram already have something handy?
I'd guess because they could get the core module more cheaply if they
used something at least semi-standard. Also, Imlacs were designed and
built in Waltham MA, probably be ex-Dec people...
