Re: Debugging ATOM with ATOMMC2

What I remember from playing with WD65C02s is that they would work in the Atom, but would not work with AtoMMC. I did try a WDC6502 which was in a KIM1 clone I have and that didn't work either. I guess the rebadged MOS 6502 I tried it with from my System 1 build may well have been a WDC65C02 too. T...

Not sure if this helps but did a bit more investigation with a NMOS 6502 which will boot the ATOM but not with ATOMMC connected. LK3 is connected and I always get the busy like flash on power up or break. Looks like the bytes being read from the ATOMMC2 more often come back as FF I can’t get the ATO...

R14 is 4K7 which is spot on

Re: Debugging ATOM with ATOMMC2

What I meant was: if it's initializing correctly every BREAK with a SY6502, then there is no need to update the AtoMMC firmware.

(I don't want to add any more variables to an already complex situation).

Okay Dave, will report back when I get another SY6502.

Re: Debugging ATOM with ATOMMC2

If your system is initializing correctly every time you press BREAK, then there's no point. Apologies if I was not being clear previously. It never initialises with the MOS-6502 Power on, Break, CTRL Break all give the same as below (The ATOMMC2 SD Card adapter busy light flashes on each break pres...

Can you say a bit more about when it hangs?
