Calling all Twentieth Anniversary Macintosh owners!

Attention! A reader has an old TAM that won't power up. He asks whether there are any shops currently performing TAM repair or are interested in buying a TAM for parts. 

I came across an interesting online discussion at Apple Fritter, offering one possible fix (internal reset button) for a TAM that won't power up. It'd be great if that fixed the reader's problem!

I don't know any repair shops currently offering TAM service; I've seen some old links on old TAM sites, which are now dead. I would search for any and all shops offering Mac repair, and inquire whether they can fix a TAM, or whether they'd buy for parts. (Regarding parts, there's always the eBay option. I know many people look for TAMs on eBay; they usually want working ones, but there could be someone looking for a dead unit to cannibalize.)

Hmm, a really dedicated do-it-yourselfer could get hold of a PowerMac/Performa 5500, on whose motherboard the TAM is based, and scrounge parts from there. Naturally, I can't offer any guarantee that such a transplant is a good idea; it's an idea for the brave!

In any case, a question for all: Does anyone have info about shops offering TAM repair, vendors buying or selling TAM parts, or other advice about TAM troubleshooting? If so, please comment; I'd be happy to add good info to my Twentieth Anniversary Macintosh overview.
