Philips mini computers

[Nigel Johnson]

Are we talking about ISA-bus computers here?  If so the colour graphics 
card was a Persyst Bob card, and the bi-sync adapter, if equipped, was 
also made by Persyst.  I know because I signed them to the contract to 
buy those two items. I know about their high standards of Quality 
Control because they rejected about 1/3 of my initial shipments!

In 1985, every computer that included a CRT made by Philips was made at 
their factory in Ste. Laurent, QC, or so their engineers told me.

cheers,

Nigel (then known as Bill) Johnson
