The original HP150 (9" CRT, always has the touchscreen) can have the printer fitted in the top. The HP150-II (12" CRT, touchscreen is a somewhat uncommon option) can't

There are considerable hardware differences between the 2 versions. I have both along with the technical manuals. The older one is mostly standard ICs, I think there is one HP custom part in the graphics circuitry. The later one is stuffed with ASICs, alas.

Incidentally if anyone is restoring the oriignal version and needs the printer, I probably have at least one spare.
