It's not 'the first book of kim' as I recall it exists, but the original manual.

It's a reprint organized by a member of the German forum forum.classic-computing.de , only those three were reprinted

Talked to him and he explained the reason which I understand. Still a pity. I will look into using the UCI for GeckOS then

I think it would be interesting to investigate if, in the absence of external drives, instead of slowing down the C64, speeding up the drive instead would be possible

I know. But I am building my own FPGA based Commodore PET replica. So, I think it could have been done. I accept if there is a technical reason I don't know, but just 'that's because it was like that' doesn't cut it for me.

Ah well. The VICE emulator - all software though - speeds up the C64 _and_ the disk drive(s) at the same time in warp mode.

Not to spoil the fun - but the VICE emulator speeds up the C64 _and_ the floppy drive in warp mode. Which is very convenient

@commodoreofficial.bsky.social
I was wondering, if I speed up the C64 to say 64 MHz, it seems the 1541 emulation is not sped up, but instead the whole machine falls back to the original speed when accessing the disk.
Is that intentional? Will that change? Thanks

Spahn redet die NATO um Kopf und Kragen und fรคllt Merz in den Rรผcken. Die Sicherheit in der Arktis und von Grรถnland ist ein NATO-Thema. Trump stellt keine Fragen sondern versucht, Dรคnemark und Grรถnland zu erpressen. Das ist NICHT โ€žnachvollziehbarโ€œ.

Als wir die AfD fรผr ihre verfassungsfeindlichen Ideen von millionenfachen Vertreibungen verurteilten & zu Millionen auf die StraรŸe gegangen sind, fiel sie von 23 % auf 15 %.

Seit wir sie "inhaltlich stellen" & "endlich hรคrtere Migrationspolitik" machen, stieg sie von 15 % auf 25 %.

Ich sag's nur.

I have resurrected my 36 yr old solution "BDOS" for copying files to/from a PC floppy with a C128 and a VC1571 disk drive, that once was a 64er Project of the month.

Follow me on that journey!

I'm still looking for a (working!) tool that limits the CPU freq automatically once a temperature limit has been reached.

I actually finally seem to have found a tool to effectively limit the CPU speed and thus avoid overheating....

caching changes is basically tracking deltas (if you don't want to compare the whole model on save - that depends on the model size) and a difference only comes in if consecutive changes affect the same parts of the model.2/2
