A little over 34 years ago, Acorn Computers Ltd released a budget version of the BBC Micro, the Acorn Electron. For a time it was apparently the best selling Micro in the United Kingdom, although in more recent years the Electron seems to be overshadowed by its big brother the BBC Micro.

New features :
48M XRAM mapped as Chip and all chipset DMA pointers support 64M addressing (optionally enabled in OSD / .ini file)
CPU cache stable - 2 way I + D with full snoop. ~16000 AIBB Dhrystones
Filtered & Mono audio
RTG over analog/DVI/HDMI with hardware sprites and dedicated blitter engine. 1024x768 at 16...
