content: I was recently given a 24 pin chip with label "C64".Photo of chip and what remains of markings is attached.You can have it for free, unless you want fast/registered post. PM me to discuss.

content: I have a C64 breadbox in decent shape. I bought it untested and have no power supply to see if it works or not, but it still has all its original chips. Yours for $20 shipping. I can get pictures tomorrow

content: Quote from: marshallh on April 22, 2017, 05:06:11 amIf you don't want to use the tape, or the RTC in the VIA chips (which even the C64 KERNAL doesn't use), you don't need the 9V AC, just the 5V DC to test it, if you have a DIN connector, or just 2 pin heads.

content: Quote from: marshallh on April 22, 2017, 02:25:36 pmRight, I forgot that. But it still works with it, just no sound. I think you could feed just 12 V DC in the 9 V AC connection, to test the SID, too:http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/c64/250469-rev.A-right.gif

content: all kinds of info I didnt know as a kidI loved geos and the 1581 drives when I got them. had a c64 software/hardware store near me back then. berkleigh or something.. forget the name really..but yeah really interested in this let me knowstill want all the c64 c128 stuff I can get, eventually I'll get some amiga stuff too maybe.

content: I don't think the SID requires anything besides 5V, but the serial UART does.

content: Quote from: james_s on May 01, 2017, 04:57:36 amThe SID does require 9 V or 12 V (depending on the version), see here:https://en.wikipedia.org/wiki/MOS_Technology_SIDThere is no dedicated serial UART in the C64, but the user port has the 9 VAC lines, too, which is used by some devices, like modems:https://www.c64-wiki.com/wiki/User_PortAll other signals, like the serial port on this port from the 6522 VIA ICs, are 5 V TTL.And finally there is the cassette port. I think the 6 V are derived from the 9 VAC, too:https://www.c64-wiki.com/wiki/Cassette_Port

content: Interesting, I see my memory was a bit off. My friend restored a C64 a few years ago and built a power supply for it but I never had one myself. My only C64 is in an FPGA.
