Okay, thanks for the details. You’re right that probably makes it difficult, but not impossible.
Has anyone documented the protocol for the D2 colour DIS anywhere?
I’ve made a start on the monochrome DIS protocol
here...
I don’t have a A8 to be playing with, so can’t investigate myself. Not sure I’m up for getting an A8 cluster and trying to build a test harness unless I know more about what’s involved.
The RNSE firmware has code for communicating with two kombi (cluster) types:
One is called “mono” (fairly obviously monochrome I would assume) in the debug messages. This is the one I’m used to in the 8N/8J TTs.
The other is named “hicol” (maybe hires colour?) and I’ve no idea which model that was used on, or even perhaps NOT used on, but perhaps intended for... any clues?
I realise this is a niche market now, but that’s not the point for me. I’m interested in fixing things, but to do that I’m probably going to need help from someone on the A8 D2 side. I can bring all the necessary RNSE patching experience. I’ve stamped on a huge number of bugs and niggles in the RNSE firmware already, plus a few enhancements along the way.
