Most of it is sort of a re-hash of Zmag issue #124 (thanks Gary Duzan), so I'll try to keep it to a minimum. BTW, this is reprinted without permission (but surely I can claim exemption under educational use). PS: My editing is in between the [brackets]. From Computer Shopper November 1988: ''The 'Turbo 816' by DataQue, for the Atari, will be available by mid November for a suggested retail price of $99.95 (probably discounted by most vendors). Included is a circuit board that replaces [the 6502 and OS chip]... A debugger for 16-bit assembly language programmers will also be included, and a complete Assembler may be offered either separately or with the pack- age. On the new five-chip Turbo 816 board is a powerful 65C816 processor that retains the 8-bit instruction set but has a ful 16-bit set as well... The Turbo 816 [can address] a fully linear decoded address space of up to 16 megabytes. ...existing upgraded memory machines will be suported by the Turbo 816, no matter which flavor or size...Users of the new CPU system will see an immemdiate speed increase in all their existing 8-bit software. [To quote one of the designers] 'just enough to tell there is something different.' The OS chip has much faster I/O routines to all devices, making disk access, screen writes, joystick response, almost everything faster. However, the actual 'pace' of most software will be typically unchanged...math is all being done with new routines that will dramatically surpass computation times of the standard system... But the real power of DataQue's device will be in the future applications utilizing the 16 bit mode. Machine code will be 20 percent smaller and up to 20 times faster than that written in the 'native mode' 6502. [Here's a goodie] what is even better, disigner Ron Shue has arranged for memory registers and stacks to 'hold up' under a mode-shift, enabling a programmer to code half of his application in 8-bit mode, say to make use of existing CIO/SIO disk access, then shift to 16 bit mode for computation and processing -then back to 8 bit for more I/O-and on and on... As for the new operating system, as I mentioned it retains the vectors, flag, and entry points of the Atari OS, but is virtually 100 percent re- written for optimized function with the new CPU. Included is a much improved floating point package, a real resident R: device handler...and room for lots of exciting things to come...[See Zmag issue #124 or back issue #92 of Info-Atari8] More about compatibility: Ron Shue [co-designer] has bent over backwards to be certain that Spartados, Real-Time-Eight, MIO, and hard disk users will have no ugly surprises after adding the Turbo 816. Only a tiny percent of programs ([ones with illegal calls]) have had problems with the new operating system. Chuck Steinman [co-designer] says that later upgrades in the operating system chip will be offered to all users at virtually postage costs, and Ron is expecting to offer a piggyback system software control, for those who want to be able to shift between their old chip and the new one [Omniview/Omnimon users]. [And last but not least, but the *most* interesting tid-bit] DataQue is looking for qualified developers to be the first owners of Turbo 816, and are looking for ways to add incentive for rapid application developement... What does Atari Corp say about all this? [They have talked with Atari through out developement fearing a blockade like the one involving the ST 8-bit emulator. The article says that Atari has been 'generally supportive and helpful ths for, although DataQue is still waiting for written clearances on their operating system.' So they won't get sued later. They had hoped to convince Atari to put the 816 in new XE's, but Atari says 'Why would we want to redesign the 8-bit machine to be competitive with our own ST anyway?' But Apple did it! (Sen. Bentsen: Atari you're no Apple computer.)] Developers and other interested users can contact: DataQue ONLINE at: Chuck's BBS 'Master 800' 3306 Bank Avenue West or 419-529-5197 PO Box 134 GEnie: R.SHUE Ontario, OH 44862 GEnie, DELPHI, Compuserve: DataQue Acknowledge-To: Scott Parish
