At the time of cpc release, the majority of enginners was graduate recentlly. Mej electronics was found litte time early.

The university subject "electronics" may have been new, but there were certainly lots of electronics experts that had been around for years, just that their course had been called electrical engineering. Commercial electronics started before the 30's, more than 50 years before the CPC arrived.

Electronics in general yes, but i not speak about it,  i speak about design a home computer. the industry in these time was very new, taking apart the big room industrial computers.


I mean not how build the electronics part, if not the overral design of  how the computer works. how screen is accesed, bus configuration. etc etc.. resolution modes etc..


Mej electronics/amstrad go for the easy part. they take reference of what it exist and take this  reference to desing the computer.

For example video modes are a  a variant of cga.

Looks like a simple gate array.

Well it could have been an ASIC or a custom IC. This is the ACID, not the GA.
