Description
Epson Colour Board Q505A-E
New and boxed (but has been in storage for some time)
This 8-bit ISA expansion board was used in the Epson Equity 1 and 1+ computers.
It is a CGA-compatible TTL colour graphics/text mode board with the option for composite video output.
PCB markings: “EPSON COLOR BOARD MODEL Q505A”
If too dated to be of use ‘as is’ these are full of retrievable chips!.
These came to us as a surplus item from a large computer research and tech Co. as new still in manufacturer’s sealed packaging.
As they have been in storage for some years we have classified them as new other.
