As I understand it, after Amstrad bought the computer business from Sinclair, until the +2 (grey) was ready for sale, Amstrad continued buying the machines from the actual manufacturing company that made the ZX Spectrum 128. Some can be found with parts that have Amstrad part numbers.

was there any difference between an investronica 128 and a sinclair 128 ?

Yes. Different PCBs and different ROM code.

is the rom for a investronica 128 available ?

I think so...

Hi Mark ,


i found some schematics marked as investronica , and one spanish rom image .

i assume the video output is the same for both versions , but only a real schematic would reveal that i fear.

= pin-out of the rgb connectors differ !!

i will try to make an eprom to see if it does work ......
