A HP 9100 complete with extended memory, plotter, printer, interface
buffer and all the manuals. Made in 1968. The 9100 uses no ICs only dodes
and transistors. The memory is core. The readout shows the contents of the
X,Y and Z registers. It's built with a CRT that has been masked off so that
only three lines of data are displayed (X=xxxxxxx,Y=xxxxxxx and
Z=xxxxxx). You can see more at

I also have a DG Nova 1200 but I don't know how old it is.
