jhd Posted March 30, 2015 Share Posted March 30, 2015 In about 1983 or 1984, I recall seeing a listing for a high resolution graphics board for the Model III (and, presumably also, the Model 4) in the Radio Shack computer catalogue. While I had some access to a Model II at the time, it just had the stock hardware. Is this graphics board supported by any of the TRS-80 emulators? Is there any software that actually uses it?

Hi yes, check out Matthew Reed's emulator: http://www.trs-80emulators.com/trs32/ The registered version supports them: High resolution graphics (Radio Shack and Micro-Labs). There were some games that were made to take advantage of the boards, but beyond that, not sure. The original boards are very very rare. If you do happen to own a real Model III or 4, someone has recreated these graphics boards and a guy from Australia is currently building versions for sale: http://www.vintage-computer.com/vcforum/showthread.php?46326-EOI-Model-III-and-4-hi-res-graphics-board-reproduction-kits And if you have a real Model 1, this device incorporates them as well: http://home.comcast.net/~bartlett.p/MISE/ 1 Quote Link to comment Share on other sites More sharing options...
jhd Posted March 31, 2015 Author Share Posted March 31, 2015 Unfortunately, it does not look like there is very much software support for any of the various hi-res boards that were made from the Model III. All I saw was a port of the original Space Invaders. It is a great technical achievement, but I can pay it on (many) other systems with far less hassle.

+sm3 Posted April 1, 2015 Share Posted April 1, 2015 There is one for sale on eBay now. I'm not sure I'd pay the current price for it, it's approaching the cost of the hard drive emulator which I think is far more useful. http://www.ebay.com/itm/161654761787 It's truly a niche item. But then again, TRS-80 items on the whole are rather rare these days. Quote Link to comment Share on other sites More sharing options...
+sm3 Posted April 3, 2015 Share Posted April 3, 2015 I guess the final selling price for the Model 4 (not 4P yet) version is $179.99. A dedicated page has been created and it provides a little more information: http://ianmav.customer.netspace.net.au/hires/hires.htm 1 Quote Link to comment Share on other sites More sharing options...
