Subject: BBC Master 512K Upgrade to 1024k

 
Hi

Shortly after the BBC Master 512k was released, documentation was available
to complete DIY upgrades to add another 512k RAM.

At the time I never complete the upgrade due to lack of funds and cost of
ram.

Completing a PCB today for this upgrade shouldn't be a problem, but from
what I remember new eproms were required to address this memory range.

There was a company that was producing these upgrades commercially.

Does anyone have images of the roms on the Daughterboard or completed PCBs?

Regards

Andrew
