Anybody out there purchased the VXL-30 accelerator from Microbotics? I'm interested in anything anyone can tell me about problems, quality, compatibilty, etc. Mark Kelley 70771,176

Mark, I too am interested in the VXL-30 but like you cannot find any useful information about them, but it does appear that they do not yet have any memory boards actually available which limits thier potential greatly. Also from what I have been told by dealers it seems that the boards that are in development are 2 or 4 meg and that the boards cannot be expanded i.e if you buy the 2 meg and want more you will have to throw it away and purchase the 4 meg! not really ideal. Another thing I would like to know is that if I purchased a 40mhz board does the `882' run at 40 or 25 mhz?. Looks like it has great potential Mark but as yet only seems like half a system…..let me know if you find out more. Paul Paul Plymouth,England

Paul, I talked to a salesman at Briwall and she told me that 2 and 8meg boards are available. She thought that the 2 meg board could be made into an 8 meg board by changing out the dram (of course that means wasting the 2 megs already installed). Your correct when you say it is less than ideal. I'm going to call Microbotics to get more details. I'll put your questions to them also. Mark Kelley

I called Microbotics today. They said they are not shipping yet. Dunno what the real scoop is.

I have the VXL 40-MHz board. On balance, it is a good board, however, the memory boards are not yet out (MicroBotics claims they are days away from release, though) and that means the speed increase is not all that you can expect (I figure I have about 5 wait states until I get the burst memory board <g>). But they are pretty reliable and most commerical software works just fine. Even the stuff that breaks often works if you turn off the 68030 cache. The coprocessors can run at any clock speed; if they run at a speed other than that of the main chip, then you have to get a clock chip (about $10, so no big deal). You need a PLCC coprocessor, though, which isn't as common as the standard ones, but you can find them anywhere, it might just take a bit longer to dig one out. Bob
