CCS 7720 Parallel Interface Manual ?

Is there anybody willing (having the above card including the manual) to scan and upload the manual ? It seems to be that this is not available at the internet.

 

Many thanks

I have scanned the manual for the CCS7710:

CCS_ASYNC-SER-7710.pdf

 

The ccs7710 has the same proms for firmware as the ccs7720. It is highly likely that ccs used the same interfacing method on most of their early cards.

 

here is a lot of info:

The hardware of the 7710 (serial), 7720 (parallel) and the 7811 (APU) is very similiar concerning the PROMs and even driving the functional chips (6850, 6821). Why not? :-)  Even the layout seems to be similiar.

If you look at some boards i.e. from IBS it's the same. They also shared parts of their design with several products.
