Damn - you're out of luck. For _years_ after I owned one (or ever touched an Amiga) I had images of the 2 ROMs for A2630 (as well as the jumper info etc.) on my HD. Gone now though :-/
I inherited a 2630 - put it in my 2000 (or was it 1500 ?) which had KS2.0 ... didn't work - but as I was doing bits of work for a company registered as a C= developer, I persuaded C= UK to send me a pair of ROMs, which a mate then blew for another mate in posession of an old 2630 .
Haaah, happy days :-)
