Honestly I think it is much easier and cheaper to get an X-series cable (XE1541, XM1541, XA1541 etc), if your PC has a parallel port. Since you imply your PC has a 5.25" floppy drive, it should have a fairly decent parallel port as well. The Big Blue and Little Red readers will read and write to a MFM formatted floppy disk. I think you even need internal modifications on your 1541 to use it, while a 1571 would work out of the box.

Hi people, I'm still working on this C64. Update: Fized the color isue (I get working moving a pot which is connected to the VICII's color out in this board. I moved it and got color But it still freeze. Tested: MPU (exchange betwen e working 64) CIAS KERNAL - ROM CHAR ROM 82S100 PLA VIC II New 74LS629 for the VCO's. Checked power supply. I changed filtering caps. Also, the two on board regulators on the C64 are new, and the...

Sounds like it might be at least partly heat-related; maybe try cooling the various chips with a cooling spray or a well-wrung-out cloth soaked in alcohol?

no, he lives near to Vienna

Thanks Anders...yes, I couldn't help thinking it was terrible luck, regardless of how old the equipment is. I've actually used the same ps to test them all (a known good supply), so I know it isn't it. I checked and rechecked my pinouts (thinking of the old 5 to 8 pin differences, wondering if there were two 8 pin configurations or something) to no avail. Thanks for the link as well - I'll check that out and see if I can...

Can you post pics? The last time I saw a C64 that had short multicolored horizontal lines on it the PLA chip had failed.

The ROM should be easy, esp. if you start with a Fat 40 (thanks to Matt); my 2001 has a ROM that can switch between BASIC 1 and BASIC 2/3, same idea. Presumably you could use a bit in one of the VIAs to do the switching. What would you pick for the actual switches/multiplexers? I think...

Mostly it's a space saving move. I have my main machine (Windows), but sort of need a slower machine for vintage work, ie. disk images of other machines, and for development for my TI CC-40. Seems the PC Interface program was written with slower machines in mind and randomly crashes with faster machines. Besides, I like playing with DOS from time to time. That and I like the old game Faery Tale Adventure. I've beaten it several...

I've got a brand new copy right here! ..but it's commercial software, I don't think it's been widely distributed. There's a clone called Little Red Reader that did the same thing and was free, maybe that one would show up in a search.
