As a sort-of aside, the HP110 and 110+ (Portable and PortablePlus)

row of 6264s (8K byte static RAM chips -- my Portable+ has, IIRC, 112 of

there's a PCB the size of the base of the machine containg the CPU, ROMs,
a bit of support logic, and loads of RAMs

Why not build a static ram card -- no dynamaic
ram and really speed up the pc.
Back in the day, fast static RAM was fairly expensive. Of course,
you could do this today, but where's the fun in that?
