There's the "WDC" (https://www.westerndesigncenter.com/) with modern 6502 derivatives. Yet they are all the CMOS variant descendants, which I recall were not 100% compatible with the original NMOS based 6502. AFAIR especially in the undocumented opcodes realm. Is there anything fully NMOS 6502 compatible (other than the actual 6502 in PDIP) available? PLCC44 would already be OK. I take there are VHDL implementation(s), which should be fully compatible, but other than that?Received on 2022-09-03 21:00:03
