My notes from doing my own actual machines.
I haven't done my 200 yet so no 200.

Hi,
I see Arcade Shopper has a Tandy M100/102 capacitor kit. Does anyone
sell a kit for the NEC PC8210A?
Thanks,

Subject: [M100] Looking for an old Jake Commander article
Hi all,
The article, Commander, Jake. "Disassembling the puzzle in your
100's ROM." Dec 83:41-43 appears to be partially missing from the
scanned copy of the Portable 100's Dec 1983 issue on club100.org
<http://club100.org>. Does anyone have a complete copy?
Thanks,
Will

Given that my new m100 is 39 years old, should I expect
that parts need replacing inside?
The generally accepted wisdom seems to be that when doing
intake of a "new" 100 to replace the NiCd and all capacitors
ASAP. They risks to the life of the machine. A 102 may not
need capacitors replaced quite so urgently, but that NiCd
still has gotta go pronto.

I just wanted to say thanks for the tip. I have a Model 100 being
delivered from EBay today, and I already ordered a battery and a
caps kit.
