Is there any more information on this? Specifically, are there schematics and so forth?

This is probably an updated version of the famous 'Turbo 8/16' upgrade which was originally made by Chuck Steinmann/Dataque (he also originated the v. first stereo pokey upgrades 'gumby') and was planning various modifed 8bit compat. machines based on the turbo 8/16 upgrades with better sound/graphics hardware designed around tower/pc cases (for easier access) after that, various other American Atari hackers came up with their own versions, including Bob Wooley (who originated the dual Antic/Gtia upgrade) and CSS apparently had a version as well

 

The original turbo 816 upgrade was imported into europe/uk by BaPAUG (which i was a member of) and Chuck Steinmann used to write regular columns in BaPAUG's news letter about the features and applications (incl. programmes) for the turbo 8/16 upgrade (i have 2 or 3 old news letters with the articles but no scanner... sorry

 

The Ironic thing about Turbo 816, which i guess is what this upgrade is based on/around.. is that Chuck steinmann originally offered this to Atari themselves (as it was is intention 'originally' to use a modd'd version of the atari o/s (800/xl/xe) and interface it with this new processor and upgrade) the problem was that, because all of the 'miss information' that existed about the upgrade at the time (people were claiming it compatible with the St and all that) Atari basically nixed a deal by asking for too higher cut/percentage for each unit sold, and also because all the miss information that already existed about the upgrade, they (atari) didn't want to associate themselves with a product that could potentially cut into the ST's market and therefore affect ST sales (a'la AMIE chip scenario, if you know my meaning)

 

Additionally, the turbo 816 upgrade was the first time the this processor had been used by a computer/games system other then the super nes and Apple2gs, the commodore 64 equivalent 'the super cpu' upgrade didn't appear until just recently

 

Atari also had a hand in the original design of this processor and sold the design to what turned out to be WDC (western design centre) during the tramiel/warner transition period

actually 65816 1,76Mhz or 6502 1,76 Mhz, soon 14Mhz

Well, I cannot read polish yet, so not sure whats going on on that page, but it looks like it might be good. If you really do make an upgrade board to put a 65c816 into an 8bit, I sure would buy one. The software I can write myself.

Ah, I see there are schematics embedded in all that Polish. It really does look simple. Anybody feel like making one of these?

This kind of idea is interesting. To really take advantage of the CPU one would need an updated OS ROM though. I'm planning to get a ROM progammer eventually since I need it for a few different projects. Maybe by that time the hardware gurus will give us a large, linear RAM and more speed to go along with the 65816 CPU...

Draco has a new OS up and running for this.
