well how many transistors does our table top straight pdp-8 have?!

Which of course harks back to the Bletchley Park systems built on
narrower but similar
British Post Office 19" Relay Racks. The predecessors of the modern 19"

I seem to remember that the Packard-Bell PB250 used only about 400
transistors. (Magnetostrictive delay line memory). Lo

The physical layout concept is actually quite similar to Harry Porter's relay

Good luck to you sir. Its a living animated schematic.

be called a DuellProcessor. :-)
