Sharp CE-150 printer/cassette interface questions

[Xorand]

Welcome to the club. The PC-1500(A) and Tandy PC-2 are my favorite of the pocket computers. Still readily available and fairly powerful even compared to many later iterations of pocket computers from both Casio and Sharp.

I have several brass gears I picked up from Jeff_Birt and have a nicely working CE-150 and a Tandy Printer/Cassette Interface (just a rebranded CE-150). I have them paired with a PC-1500A and a PC-2, respectively.

I rebuilt my battery packs with solder tab batteries, but recently picked up a spot welder and another box of batteries to rebuild the battery packs a little more compactly. The battery compartment is pretty tight and stray solder tabs tend to take up additional room if not placed just so.
