Is there anyone who sells replacement semiconductors kits for the HW-8?

Bill-

Parts used by Heath may not have been so obscure back then! However
they did mark them with their own proprietary numbers. Therefore you
need a cross reference before you can see how common they are.

I found such a cross reference at
http://www.d8apro.com/heath3.htm which has quite a long list of Heath
part numbers.

That web site has additional Heath information at
http://www.d8apro.com/heath1.htm .
