What roms are these??

[melott]

I have an A2500 with a 2630 accellerator.
This accellerator has a set of roms on it.

They are......... 28 pin roms

I did a Google search and it says they are Commodore
kickstart roms.
All the roms I've seen are 40 pin.
Are these A1000 roms or just what are they ??
I know they made later versions (which I want/need).
I've read this on one of the tech info sites.

Any help??

My guess is (considering the age of the machine)
they are probably 2.04 or 2.1 roms.
The question is did any Amiga use a set of 28 pin roms?
If so which one ??
I don't know where to start looking for these roms.
