NEC PC-8201A Electrolytic Capacitors & Battery

Capacitor kits for TRS-80 Model 100 are fairly common. All electrolytic caps needed to re-cap an NEC PC-8201A may be found in any Model 100 cap kit. So the most convenient way to get all needed caps is to just get any Model 100 re-cap kit. There will be several caps left over not used in the PC-8201A, but none missing.

Similarly, the memory battery is the same in both machines.
