Hello.... Does anybody have a source for prototyping boards that fit the C64 Expansion Port? The local supplier I used to get them from can no longer obtain them. The unusual 22/44 pin port with the unusual spacing makes them a little difficult to find. I need something reasonably large, large enough to hold a few good size chips. I don't want to try "making" one.... a lot of work. Thanks much.... -Joe -- jgreco@csd4.milw.wisc.edu Joe Greco at FidoNet 1:154/200 USnail: 9905 W Montana Ave PunterNet Node 30 or 31 West Allis, WI 53227-3329 "These aren't anybody's opinions."

I just grab a 72 pin board from Radio Shack and cut the extra off with a knife. The spacing is the same. It's looks ugly, but it's pretty easy, easy to find and sufficient for a prototype. Devon

Radio shack sells one prototype board which is about 5" by 6" and has more edge contacts than required (i.e. >22 contact double sided). It has solder pads at each of zillions of 0.1" holes, plus pads for the edge contacts. 5 minutes with a hacksaw and a file makes it into any shape C64 expansion port board you want, including one which will fit into a standard cartridge case. I don't have the R.S. number, but it is the only board they sell with 0.1" edge connector fingers, so it shouldn't be too hard to spot. I assume R.S. has the same product line in Canadian stores. The board is not epoxy-glass and the edge contacts are not gold plated, but then again, it only costs $5. Sincerely, Frank Prindle Prindle@NADC.arpa
