Wow, cool work! I will try it in the next few days, hopefully!

Thumbs uppp!

I got the pdf link too and wow, incredible pages: full of info and with wonderful pics! I can see and feel all the care you took to put all the pieces of this work together. Looking forward to receive my copy on paper!

Grazie mille!

Hi, mine is obviously based on the two assembly opcodes LDX and STX (sounding a bit better than LDASTA ).
True love for the 6502...

Thanks again for this wonderful forum and friendly community (btw is nice to be back after 3 years of sporadic lurking because of work...)
Ciao!

Thanks Mike! (I was writing my post when you submitted yours)

I think that's because I can't use an absolute value for the comparison, since we don't know how much time has passed since the last update of the low byte of the jiffy. (EDIT - I meant: I don't know the value in the byte when our code executes. Thanks again Mike for your way better explanation)

Thank you all, @Mike: the first routine is perfect to my actual needs, thanks! Even with that working solution which uses SBC, I'd still like to understand why even this new code snippet won't work (the update pace is not constant in a remarkable way): wait: lda JIFFYL cmp #60 bcc wait rts Greetz

Hi :), I have a problem with my following test code: when I use the registers to control the speed of execution everything's ok, but not when using the low byte of the jiffy clock. I tried to look for some info to solve this in the PRG with no luck. Btw: any ML mentor out there to regularly speak to...

Sorry for the OT post, but: Pallas welcome to Denial!

Happy to find some other Vic fan still active and just 70km away

Hi! :) I've just bought a 1541 (Newtronics) like this one: http://upload.wikimedia.org/wikipedia/commons/thumb/1/1b/Commodore64_fdd1541_front_demodified.jpg/320px-Commodore64_fdd1541_front_demodified.jpg When I turn on the drive the green led stays on, the red one on for a second and then it turns o...

Wow, great! Really inspiring! Atm I wish I could do that too

Thanks for your post.

Ok: found'em!

@OBSysteme thanks anyway

Thanks for your quick reply! I'm searching for a hard copy (I've got the digital version).

Dovuta precisazione: sto cercando le copie stampate dei suddetti testi (sono già in possesso della versione digitale).

Ciao, sto cercando la "Programmer's Reference Guide" sia del Vic-20 che del C64 ad un prezzo onesto; se qualcuno ha qualche notizia per cortesia mi contatti in privato. Grazie! Hi, I'm searching for the "Programmer's Reference Guide" for both the Vic-20 and the C64 at a moderate ...

Hi and welcome to Denial!

Ciao!

Yes, now having a working Vic-20 to me is like a victory :) Btw I'm already thinking about purchasing a second one :D (a second C64 is arriving the next week too and all of them will sit next to the A500 :P). Many thanks for the idea of the PSU hack: will wait for news about the voltage readings the...
