Denial

there is no evidence for either, neither that it "works" nor that it does not. it'd also be hard to produce such evidence :) (anecdotes do not help) however, its undeniable fact that a circuit like this is relatively slow, and would expose the output to high(er) voltage much longer than de...

But is there any product you recommend we use that is new? not a specific product. i am using a C128 PSU myself, which is quite a bit better than the C64 powerbricks. should that ever fail, i'd probably just build a replacement myself :) a good DIY variant for ppl without any electronics knowledge ...

US Army trained and was dealing with electronics before most of us were born.

that doesnt make this circuit any better really no doubt he has published some good stuff - but there is no doubt some of the things he made are a bit questionable either.

ah modern circuit should have a crowbar circuit to prevent overvoltage on failure... even THAT can not be fast enough in some situations, but a relay certainly isnt. a relay based circuit can only ever protect against overvoltage which raises relatively slow while the PSU is being used - however the...

conio is optimized portable console output, so it doesnt understand any of the petscii control codes... if you want that, use stdio functions, putchar() would be the function that can do it. that said, its probably a better idea to write to the respective VIC registers directly (someone else can pro...

indeed it is. there should be a separate test program just for this =P

i guess we really need 1541 versions of those tests (ie its not really a VIA emulation thing - its a VIC20 specific thing here)

he just had is regular outburst and ragequit over some silly argument on IRC. he'll be back in a year or so. its not the first time this happened

is that Sav64 the placebo thing that will safely cut the power with a relay.... a couple hundred microseconds after the C64 was fried? that said, yeah, dont use the old PSUs. dont use those silly "saver" circuits either. a plain simply new modern PSU will do the trick (even more so for the...

as usual, managed to miss most ppl i was looking for =P

what funky assembler is that?

in most non trivial code all the fancy optimizations will get lost in the x86->6502 translation and you'll end up with code similar to what cc65 produces

perhaps even try higher values... you shouldnt need much current (almost none) afterall

and yes 15 years ago it was easy to get deals like that... i wish i had got myself a stack of plus4 and vic20 too.... i only got a dozen C64s and drives

you cant rely on those testers, not seldomly oldish chips work fine in a tester that only puts very slow signals on a chip, but on a mhz or two it fails

i'd perhaps even use 470Ohm - but looks OK to me
