The A500 (and for that matter, A600 and 1200 too) have a separate line for the Ctrl+A+A signal, and all "big box" Amigas have the same scheme for the reset as the A1k.
If you remove transistor Q1 from the A500 keyboard, it will send a big box style reset.
This may not work on all A500 keyboards, though. Your mileage may vary. I have done it on an old NME brand A500 keyboard.
BTW: all A500 uses the same special reboot line, even those older ones
True
(dunno about the very 1st version, as it is basically an A1000 in other case.
False.
The lineage goes as such:
Amiga (A1000) -> A2000A (german)
A500 -> B2000
The A-model A2000 was an A1000 with ZorroII slots.
The A500 was a redesign of the original Amiga design with less discrete logic (enter the Gary). They named it the B-52 internally, as you all well know from looking at your motherboard.. They nicknamed it "Rock Lobster" after a song from that band. (yes yes old news)
When the B2000 (or A2000CR) was done (redone?), it was basically an A500 motherboard with added ZorroII slots. :-) The name B2000 comes from the A500's B52 designation.. B52 -> B2000.
Ask Dave Haynie if you don't believe me and report back if he tells you different.
