Some More 68000 Boards

First let me apologize for an erroneous statement in the May '83 issue, in which I juxtaposed two unrelated facts in a cause-effect sentence.  Many readers have sent corrections:  I am told that grounding the DTACK signal has nothing to do with how much memory you can add.  How did I ever get the idea that it did?  If you want the straight scoop on this, subscribe to Digital Acoustics' newsletter "DTACK Grounded".

Digital Acoustics has announced a new board, called the "DTACK Grande".  Almost sounds like "grounded", but this time it isn't.  You get one megabyte of RAM and a 12.5 MHz 68000.  RAM refresh is handled by an interrupt routine, with software.  The overhead is only 4%, giving an effective speed of 10 MHz.  Expansion connectors on the card can connect to another 15.7 megabytes.  I'd say Saybrook has been passed by, but Hal Hardenburg beat me to it!  (Digital Acoustics, 1415 E. McFadden, Suite F, Santa Ana, CA 92705.  (714) 835-4884)

Mike Heckman at Anthro-Digital sent me some literature on another new 68000 board.  Enhancement Technology Corporation calls it the "PDQ//".  Specs include:  10 MHZ, 256K RAM, UCSD p-system, Applesoft-compatible BASIC.  The price will be $1495, available by the end of August.  We may be able to make you a deal on one of these.
