Apparently the guy has no programs for it and is using a modified rom to make it ZX-81 compatible. He also states that he has been unable to find any resources on the net for it.
Manufactured by Lambda Electronics Limited. manufactured in Hong Kong. Z80 @ 3.25MHZ.
Possibly also manufactured as: Power 3000
Basic 2000
Basic 3000
PC 2000
PC 3000
It also sounds like it has similarities to the ZX-81 Ram expansion cards, thermal printer, colour kit, and thermal printer. He states he has the manual, but that it is just basic. 2kb basic ram, 8kb basic rom,( ordinary 2764 EPROM)
I am now assuming that it was a knockoff of the Sinclair.
