Intellivision Board details

[raspberrypioneer]

I need to try Minty myself, I must try and find the time amongst my other projects to do that.

Definitely worth it - unless you have a Sprint then perhaps less so

Been some progress I thought worth reporting. I fitted the Yannick RGB-video mod board, which @grobda sold to me a some months back. The results are really quite stunning, best video quality I’ve ever seen on an Intellivision and I can happily use my first-choice TV too. This should really be the go-to video mod for the Radofin PAL Intellivision in my opinion!

A few pics.

Along with grobda's screenshots, I found Intellivision trace map to be really helpful for identifying / confirming the video and audio inputs for the RGB board.

I used the BBC Micro / Electron RGB SCART + audio cable (modified slightly by Cool Novelties to fit the console's new 8-pin DIN socket). The socket comes from AliExpress. It needs a little modification to fit and firm into place.

And a sample result photo! I've got a spare composite video mod board if anyone wants one

Nice result it looks like a decent picture for sure.

I have been playing around with RGB2HDMI a lot of late and I see it can be hooked up to the Intellivision, so I may just give it a try:)

Is that the Pi Zero video converter project? Be interesting to see the RGB vs HDMI results you get for comparison. I can see a noticeable difference comparing RGB to s-video, but for these old computers RGB vs HDMI, not sure.

Well I built 5 RGB2HDMI boards, one went into my Amstrad PPC512 when I upgraded the screen to colour, two have gone (Or will be going) to other forum users so I have 2 left.

However as I have done with my Enterprise 64's, I added a connector that allows me to connect to the RGB2HDMI so I think that is the likely route I'd take with the Intellivision so that I can use it with RGB2HDMI. The main issue is that it doesn't include sound so that would need to be injected separately into the HDMI or fed to a separate set of speakers. Either is easy enough to do and the RGB2HDMI does have an audio feature that can be used now.

However I won't be using an internal RGB2HDMI as in the Amstrad as I'd rather use the much smaller 10 pin connector I used on the Enterprises.

Since I do have an Intellivision Sprint I do doubt the idea of doing this though other than to see how well it works.
