iAN,

It is working. I only have to give the "RUN" command to let the
program start.
So the copy routine is working.

Again: the reset vectors and CBM80 signature starts in good working
cartridges also at address 0000E000
Doesn't that something to do with the way the bankswitching on the
card is working ??

Regards, SAM

It kinda seems to me from previous discussion that you gave 2064 as
start address while it should be 2070? Which would explain why your
cart doesn't autostart.

I don't think that is fair. For one, English is not Sams first language so I
think what he means doesn't always come across correctly. I think that the
particular cartridge hardware banks in the ROM address in the 27c512 at E000
to the cart ROM space at A000 (or wherever the autostart ROM appears on the
C64) so it does appear as a normal autostart cart to the C64.

I'm not saying the autostart code is correct, but that it's not at 0000 on
the actual ROM as possibly for the reason I stated above.

dear uber-hacker, if a cart don't autostart is clearly some issue in the
"CBM80" string....

Visto, uber-hacker pippaiolo sul piedistallo ?
