This is a message by John Harris I pulled off of the Atari 8bit newsgroup. John Harris, if you've ever read _Hackers_ by Steven Levy, wrote pretty awesome games for ther Atari 800. He later when on to start his own company which used Atari 8-bit computers as displays in airports and in the hotel industry for the guests services menu on the TV (read about it in a soft-book called _Halcyon Days_). Anyway, the system he describes here sounds pretty neat.

It concerned a new atari-compatible computer made with a 65816 processor and some other cool stuff. It was being manufactured for a dedicated application that I actually never found out what it really was. I found out about it at a time when I was selling character generator software on the Atari8, and having immense difficulty obtaining Atari hardware. It was a great connection to make, and we are still selling these new systems with my CG software installed. The big project never materialized, since the company making the systems and Atari could never reach an agreement for large supply of Atari custom chips. It seemed like a no-brainer--Atari had chips, these guys had money, it should have been a simple exchange. It's no wonder Atari doesn't have any feet left. They keep shooting themselves there. Anyway, the bottom line is that Atari negotiations were the reason behind my silence at the time, and now that the project is completely dead I can make public the details of the machine for all those that are curious. It is based on a 5.37MHz 65816 processor, although it still runs 1.79MHz when accessing the base 64K of address space for compatibilty with the custom chips. It is in a nice case with internal 3.5 high density floppy and hard drive, parallel and serial, expansion slots, fully static memory (turn the power off and on, and everything is still there!), mouse support, and separate IBM-style keyboard. It has its own Sparta-like DOS, and with 65816 optimizations the memlo gets down to $FA3. I've found the compatibility to be extremely good, with two main problems. Some european programs, especially demos, use the undocumented 6502 extra instructions, and these don't work on the 65816 CPU. The other issue, is that there is no cartridge slot. Technically, it is feasible to add a slot using a plug in board, and run a connector out the back. It would probably depend on the number of interested parties for whether it was financially affordable to get the thing made. One nice thing about the slots though, they are physically the same as IBM 16-bit ISA cards. (but not electronically compatible of course). You can get experimenter boards for IBMs that just run power and have all other connections open. The do-it-yourself'er can do pretty much anything from here. Because of being a very low-production item, it is really expensive by 8-bit standards. Retail is $1800 with all options and the CG software. Obviously, it's only being sold to commercial applications like hotels and cable TV at that price. It is possible to make some deals if anyone is interested, especially for systems without the CG software. Obviously, I need to be fair to the people who are still buying the system for commercial use. I don't have any prices for you, but if anyone is interested at all, please let me know and I'll see what we can work out. If you're just curious for info, let me know that too.
