Looks in great shape.
Very similar to mine. It doesn't have the 541 board (extra 24K/Hi-Res Graphics) that mine does.
Same floppy disk problems, though. I hope someone here buys it, and then we can work together to get the floppies booting!

Re: Nice C4PMF on ebay
I bought this unit on eBay and after examining the floppy drive, I learned 2 chips on the back right were missing a pin each. That is why it's not reading the disks. So I am hoping to find another drive for the 4P-MF. I did order a legacy drive from eBay (an IBM drive) which appears to have the same connectors, but I am not optimistic it will work.
Either I need to replace the two chips (which I will look at the schematic to see which ones are bad) or find a replacement MF drive on eBay or somewhere else. Any idea where I might find one?

Hi Jeff,
Why don't you take some pictures, and post them in the "Projects" subforum. Most likely, your drives are fixable.

Re: Nice C4PMF on ebay
Thanks Dave. I'll' do that.
I am also looking for a 502 board. If you know anyone selling one, I'm interested.

Re: Nice C4PMF on ebay
Yes, definitely post photos. I will compare them to mine. I am getting close to getting mine working. I am also working on trying to get an alternative drive working.

Are you looking for the 502 board just to run ROM BASIC?tsjs2112 wrote:Thanks Dave. I'll' do that.

Re: Nice C4PMF on ebay
Sorry for the Hiatus. I'm back to my project now. I bought the C4PMF from eBay and could not get it to read any of the floppies. I( thought the drive might be bad so I found the same model on a vintage parts site. But, my new problem is the keyboard is completely deal. I can no longer see the D/W/M prompt. Keyboard seems dead. I read somewhere that someone had the same problem and replaced the 540 board and solved the problem. But, I am dead in the water as I don't have a backup keyboard for my C4PMF. It might also be the 540 board itself.
Any ideas? (I'll deal with the drive issue next)
