I passed on getting one of these at a thrift store in the 90s. Always think about it. I just couldn't figure out where it fit into the Commodore time line. There's a cart port, but what goes in it? Were carts made? Is it C64 compatible or something? No P500 specific carts were made, but some of the...

How about Denial members in Canada? Will you ship to Canada?

Just a thought: On the PET a few expansion boards (like the SuperPET board) connect to the 6502 via a short ribbon cable and then mount the 6502 on its own board. Wouldn't it be possible to support both VIC models by relocating said proposed CPU board to the back of the machine where all the space i...

Mike, how goes testing PETdisk with a VIC-20 and IEEE cartridge? Sincerely, Robert Bernardo Fresno Commodore User Group http://videocam.net.au/fcug I tested PETdisk with Vic-20 and VIC1112 interface. It works, but you have to take into account memory requirement. I tried with unexpanded VIC and a M...

So it turns out there was a related C64 version - thanks to sjgray for pointing this out. http://www.6502.org/users/sjgray/computer/rtclinks/index.html There are ROM dumps on his page too, and a manual. So, my guess is this cart works in conjunction with the commodore vic1112 IEEE cartridge. I just...

So my original reply is correct then? The OP was trying to create a partition that would spill off the end of the disk. Specifying a lower start track would be the answer. It still doesn't explain why I can't get into my partitions. The user's guide says the ending sector must be a multiple of 40, b...

I was just re-reading this and realized I forgot there were two sides, so I guess 160 tracks. Perhaps you can't make a partition spanning sides....

You need to get yourself a solder-sucker.... you push the plunger, heat the solder with the soldering iron until it's liquid, then quickly press the solder-sucker over top and release the plunger... liquid solder is sucked into the tube. repeat for each pin. takes a little practice but after a while...

Aren't there other sound [..] chips that can be mapped to the Vic. Oh yes! I expect you could map an AY-3-8910, SN 76489 or even Atari POKEY quite easily. All three of those chips produce sound equal to the VIC chip, just somewhat better frequency resolution. The SID outshines all of them, although...

That would be nice. If someone produced a cart with voice capabilities, I would buy one. But, I would almost like to see a Sid cart produced more. The Sid was capable of producing digitized voice. Sam was a good program for doing this. Also ran across a program for the Sid that lifted sounds and vo...
