frankly I just bought a cbm 710 board and was thinking to try to make adapter something like 6502 + cpld in the cpld the code to trap the 2 opcode sta ($addr), y and lda ($addr),y using sync normally one of the registers 0 or 1 I dont remember (execution) is always on the bus the second is inserted temporarily during these instructions... I'm thinking to a replacement for the 6525... I'm looking for them, hard to find :( On 20/02/2018 22:11, Mia Magnusson wrote: > Den Sat, 4 Nov 2017 17:14:15 -0500 skrev Jim Brain <brain@jbrain.com>: >> On 11/4/2017 3:59 PM, Michał Pleban wrote: >>> Jim Brain wrote: >>> >>>> If someone is serious about testing this, I am happy to write some >>>> HDL to match the circuit in the linked 6502.org posting.
