I have a c64 with what appears to be a dead power supply. Can they be fixed? Does anyone have an extra to sell? Where can they be picked up in the central Jersey area? Thanks for any help. Barry

Toys-R-Us routinely stocks replacement power packs for the C-64. I have about 6 C-64s to take care of in one of our labs. The power packs made in the last couple of years are potted in plastic, which makes servicing even the fuse pretty nasty. If I remember right, the Toys-R-Us model was good for 5 amps and cost "only" $29. You might also thumb through the back of Byte Magazine in the ads. I think Jameco Electronics has a C-64 power pack in the same price range. For a few bucks extra, they should be able to get it to you in just a couple of days by 2nd day air UPS. Jameco also stocks replacement VIC-2 chips, PALs, SIDs, etc for the C-64. My experience has been that the SID seems particularly sensitive to overvoltage, and will burn out relatively quickly. Use care when monkeying with the power for your C-64 that you keep the voltage to 5.0 volts maximum! (on Vcc, that is.) By the way, when the new 256K ram pack for the C-64 comes out, it will include a new power pack to accomodate the additional power required for the memory cartridge. Also, thanks Commodore for making the power pack for th C-128 decent. It was about time that the fuse was made accessible without taking a chisel to the plastic blob! --Bill Bill Mayhew Division of Basic Medical Sciences Northeastern Ohio Universities College of Medicine Rootstown, OH 44272 USA phone: 216-325-2511 (wtm@neoucom.UUCP ...!cbatt!neoucom!wtm)

The Canadian safty testing outfit (CSA) thinks that "NO USER SERVICABLE PARTS" means no user replacable fuse. If the power supply fuse were replacable, then the whole mess needs to be certified in a different category. There is also some tie-in with whether or not a 3-prong plug is required. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
