Archimedes RAM expansion

Two alternate ways to extend the memory of the Acorn A3000 up to 4MB. One is a mod of a retro memory module and the other a new PCB design.
Credit to the users on stardot.org.uk who came up with these.

Wrangler, you’re a bad influence. Last time I watched your channel, I ended up dropping a wad of cash on the AA3000+. I dread to think what’s gonna happen after this video.

The A300 and A400 series were not replaced by the BBC A3000, sorry.

Wikipedia: "the 300 series was phased out in favour of the new BBC A3000"

@@wrangleramiga896 The 300 and 400 series were 'phased out' for the A4x0/1 series, later to be 'replaced' by the A5000, all of them again with separate keyboard and casing.
From Wikipedia for the A400 series : ' The 400 series models were replaced in 1989 by the A410/1, the A420/1 and A440/1,[38]' and 1989 is the year the BBC A3000 is made available, meaning both series were available from 1989, and for sure the A300 and the A400 series were phased out in favor of the A410/1, the A420/1 and A440/1 ... and not the BBC A3000.
Don't take everything from Wikipedia for granted : you should read the BBC Acorn User mags to get accurate infos.
