Re: 1541 Troubleshooting

Did you get anywhere with this? I don't know if you have seen it or not but a good place to start for trouble shooting is Ray Carlsen's CBM site: https://www.portcommodore.com/rcarlsen/ I'll quote from one of his trouble-shooting documents on the 1541: If you get "SEARCHING FOR" and nothin...

Re: Warning about WarpSpeed cartridge

Got it thanks again for the explanation. It would be cool to see this on an Oscilloscope.

As a side not, what is with the REMOVED censorship? I didn't refer to any website there, which I know is a no no here...

Re: Warning about WarpSpeed cartridge

It seems that it is more an issue on the Reloaded board. Oh, is that what it's all about? Just another incompatibility that the Reloaded board has. Well apparently not as since I wrote that it has been confirmed an issue on all 64s but will likely be very rare on actual 64s and unlikely to cause an...

Re: Warning about WarpSpeed cartridge

Thanks for the explanation. My WarpSpeed has a mask ROM in it from the looks of it. I can always use the Warp Speed ROM on an EasyFlash or other multi-cart and avoid the issue altogether I suppose. Though as I stated, 30+ years using it on and off has not done any damage. It would be nice if we coul...

Re: Warning about WarpSpeed cartridge

I have used Warpspeed since the 1980's, and I have not had any problems switching between cartridge's C64 mode and C128 mode in my C128's. Nor have I had any problems with it on C64's.

Warning about WarpSpeed cartridge

Hi All, I don't know if you have seen this : https://twitter.com/schoenfeld_jens/status/1681672737130000388 but there apparently is a bug with WarpSpeed that could damage your C64. It was found from a support case with regard to the C64 Reloaded MK2. I know there are technical people here that could...
