A3010 Production Changes

It appears the the A3010 did not start production with the well known ARM250 chipset. I have discovered that the early machines with Issue 1 mainboards had what appears to be an ARM2 processor from the A3000 on a daughter board with several other IC's of which one I am sure is the VIDC.

When production of the ARM250 chip started proper, the mainboard was re-designed and the new chipset remained throuout the A3010's life.

I have been prompted to write this after just aquiring one such early machine, it has an Issue 1 mainboard and a serial number of 01-AGB15-1011147.

The two images below show the issue 1 board, note the daughter card also known as Mezzanine and the Acorn code name for the A3010 "Adelaide". The third image shows what I believe to be an Issue 3 board which ran to the end of production, note also the CMOS battery is in a different location.
