How to read bytes from 1541/71/81 drives?
I just want to read some bytes from a certain location ($0500) of the drive. In basic i've no problems i use this routines: 10 OPEN 15,8,15 20 PRINT#15,"M-R"CHR$(0)CHR$(5)CHR$(5) 30 FOR T=1TO5 40 GET#15,A$:A=ASC(A$+CHR$(0)) 50 PRINT A 60 NEXT T 70 CLOSE 15 With this basic routine i simply ...

My opinion is that foreign languages subsection may be useful but not needful. Who translate interesting discussion in japanese/french/German to english ? I think that if we want to use International VIC section (i'm not so enthusiastic) someone, a moderator for example, need to translate interestin...

The fastloader code in the drive detects if the computer has asserted ATN instead of trying to receive bits from the drive. Yes is true but in initial loop phase only (i think). :? In effect using option LEDFLASH = 3 after the call to INIT if i just type: POKE37151,255 ($911f=$ff so bit 7 is on) th...

for an interrupted transfer you can just assert and deassert ATN to make the drive code exit. I'm tried to set ATN but i think i'm wrong in some place. To assert ATN i use: lda $911f ora #$80 ; turn ON bit 7 (ATN) sta $911f ; and rewrite but after the modify of the byte $911f, how to inform the dri...

In any case the ful...

Some helps in register Window of VICE Monitor.
Using the register windows in VICE MONITOR (View --> Register window) for debugging purpose, i don't understand some bytes and flag as show in image below. Someone know the meaning of bytes SP, 00, 01, FL and flags - and B ? http://one.xthost.info/nbla000/vic20/posts/vice-monitor-register-window.JPG
