I purchased another CE-150 but the internals were fairly well ruined by the leaky NiCd batteries (to the point I didn't want to bother with rebuilding traces and replacing components).

I'm currently waiting on a PC-2 and printer/cassette interface to arrive from eBay. Hoping I can revive this one. Not necessarily interested in the plotter as much as a cassette interface.

The NiCad battery mess is sometimes rather hard to spot externally. Sometimes on the Sharp version, the CE-158, the paint will start to peel up where the computer sits and discolor on the front. On the TRS-80 version it is painted black and hard to see any damage. Just fixed one which had some paint damage on the front but no damage inside. I have also had them look like Chernobyl inside.

The pinion gears are always broken, I do have new brass replacements available and a few extra sets of pens as well.

The PC-4 (Casio PB-100) is a great unit. A nice size and good keyboard. Have been working on a replacement for the very hard to find 1K RAM expansion modules. It seems the Tandy branded PC-4s (Casio PB-100F) may support more than 2K.
