Trying to identify which A2000 Version I just got

[Zac67]

The "CR" designation went to the American (A500 based) "B2000", as its chipset was much cheaper than the (A1000 based) very early German A2000's. So probably all 4.1+ revs wear "CR".

The community called the B2000 "A2000B" and later, when it was fully ECS'ed (1 MB Agnus, Hires Denise, Kick 2.0) "A2000C", but this was never officially used.

Don't forget to reseat the Paula chip in addition to the CIAs - might just be a bad contact in the analogue circuitry.

Not with a 1.3 ROM - AFAIR Kick 2.0+ boots from any floppy, but currently I've only got one drive and can't test it.
