Hyre, Jr. Question: Does the 65c816 option allow linear access to more than 64K in a non-GS Apple II? Will it work on a II Plus? What speed is this option? I assume that you are talking about the 65c816 option for the AE memory products. I have the 3.58 MHz TransWarp on my II Plus with a W65C802 installed, but (never satisfied with what I have) I would love to use up to 1 Meg of linear memory, instead of using bank switching. If I'm right, the only choices in peripherals are speed OR memory, but not both. The TransWarp is a fairly simple design, because it allows a 65C02 or 65C802 to be installed and only has 256K of RAM. It would not be too hard to design a 65C816-specific TransWarp (not GS) that ran at 7.16 Mhz and linearly addressed either 256K or 1 M RAM (keeping the same size, layout and number of chips as the existing TransWarp). A card like this would really sell (hint, hint, AE!).

I there anyone out there in net land that is working for Rockwell Int. or
NCR. I need some info on the 65c816, like who do I call at the company to
get data sheets and so forth.
Also is it true that someone is working on a 32 bit version?
and is the c816 truly being made to do 12Mhz?
Send mail, please.
T'anks,

You need to contact Western Design Center in Arizona for info on the 65816 or 65832, certainly not Rockwell. They make 65c02's only.

The book PROGRAMMING THE 65816 by Lichty and Eyes has the WDC data sheet for the 65816. It also has WDC's address if you need more info. I've heard for a while now that they're planning a 32-bit version, the 65832. In fact, the 832 is mentioned in the 816 data sheet, and I guess this new chip will use the unimplemented WDM instruction. I read that Bill Mensch claims he has 12MHz chips, but other companies that have actually worked with these chips say they actually run slower, at 8-10 MHz (which is still much better than 2.8!)
