Someone posted an inquiry about whether or not these accelerators replace the stock '030. Nope. They're independent, PDS cards. Also, I've now seen ads for two: The one by Total Systems (Magellan), and now one by Ventura Technologies (or something very close). Differences: Magellan: '040 PDS card for the IIsi, SE/30, fx(?). 25MHz. Retails something like $2000-$3000, depending on when you buy. (The former price is only through March, I believe.) Ventura Tech: They make two, a 50MHz '030, and a 50MHz '040. Both are available for the LC, ci. (Possibly cx also, I forget.) The '030 sells for $1495, completely upgradeable to the '040 with a FULL credit trade-in. (i.e. $1495 off price of '040 on upgrade.) The ad doesn't say whether or not it's a card or a cpu replacement. Both have ads in the March MacUser (Eddy issue), pages 30 and 319, respectively. --Andrew Laurence eaeu137@orion.oac.uci.edu

Or does it act as a sort of a co-processor and relegate periphery i/o functions to the '030? It would seem like a neat way to obtain a QuickDraw accelerator, if the '030 on board can be made to perform all the graphics routines, while the '040 board handles the actual program execution and number crunching. Is this at all feasable, or does the PDS slot not allow two CPUs to share the memory bus (or whatever bus which is present on the PDS)? Thanks for any information, I'll summarize if I receive any responses by email. Tat Chee Wan (T.C.) Grad student, University of Miami, FL Internet: tcwan@umiami.miami.edu
