Fully refurbished Sinclair ZX81 with cream Issue 1 board and very early 2C158E ULA marked with 8119 datecode (19th week of 1981). In good cosmetic condition.
Normally, our refurbished ZX81s would be fitted with a heatsink to the ULA to prolong it's life. With this ULA being significantly early and with the ZX81 being a real collector's item we have left the heatsink off in this instance.
> Recapped with quality Vishay brand capacitors
> ZX8-CCB composite mod fitted for use on modern TVs
