   Please do not publish the following information anywhere outside USENET
(i.e. newsletters or pay systems. I guess BBS's are ok, though.)
   I had a chat with Chuck Steinman on the DataQue support BBS, and he was
very helpful in answering my questions. It seems that the 65816 processor
used in the Turbo 816 is rated for 5 Mhz, though it appears it would probably
handle 8 Mhz. However, due to restrictions placed by the RAM on the
motherboard and some of the support chips (Pokey was mentioned), the Turbo
will be running at the normal 1.79 Mhz. { This may sound very limiting, but the
65816 in native mode will still be a good bit faster due to its ability to
handle 16 bit data chunks. More advanced features of the 65816 help as well
(there are two commands to move blocks of memory.) } DataQue is working on
this problem and will probably release an accelerator board in the future to
increase the speed closer to the chip's limit.
   (Info in {} above is my own, not Chuck's.)

   If you are interested in calling this BBS, the number is (419)529-5197
(I believe it is ASCII, 300-1200 baud).
