Need help with a Japanese clone CGA card HI-REL-CG-101 from 1986

[dhau]

HI-REL-CG-101 is a CGA video card from the same Japanese XT clone with chips dated 1986. I earlier asked about it's multi-function card here.

It looks pretty close to IBM CGA, lots of 74xxx chips and a 6845. What is different is it comes with two 4416 DRAM chips for a total of 32K video ram, twice of IBM CGA.

Is it possible it's a clone of Plantronics Colorplus? How can I check? Is there any software that uses Colorplus extended modes? As I understand that is 320x200 16 colors or 640x200 4 colors.


Ok, new forum software doesn't allow me to upload more then one picture per post.

Two 4416 are 16 kb in total, not 32.

Makes sense! So it is a plain CGA

I'd really love to see photos of the entire unit.
