Hi everyone,
I've got an odd card - an "Accelerator Board II" sporting 4 30-pin SIMM sticks and a large IC with the RasterOps logo stamped on it.
I assume it's some sort of video/graphics accelerator card, but I've been completely unable to find any info whatsoever.
Any ideas?
Thanks!

I have a couple of the original accelerators.
The RAM can be used for a RAM drive, or for GWORLD memory (or combinations of both).
The card was used to accelerate quickdraw for the video cards before video cards did it on their own. Drivers can be found in the normal Rasterops video driver disks.
That's awesome info! Do you think it would do any good to install the board (and drivers) in my IIfx, which is running a SuperMac Spectrum 8 board?
Thanks again - this has been a mystery for a few years now! In fact, if you type "Accelerator Board II" into Google, the only hit was a posting of mine over at the 68kMLA forums.
Best wishes,
Huxley
The standard Rasterops video driver install has drivers for the original board and the model II that you have. Just do a custom install and check the accelerator option. I don't know if it speeds up Supermac video cards but it should, also it speeds up all the Nubus video cards in the system. I noticed a speed boost when using the card (16MB RAM installed) with an older Rasterops card in a IIci.You should have a control panel installed that allows you to turn acceleration on and off, and also configure the RAM between Gworld and RAMdisk.
The accelerator will improve the performance of many NuBus cards -- do a search for NuBus bus master. SuperMac made many versions of the Spectrum 8 (and 24) cards. Early or entry level cards may not support bus mastering and thus will not be accelerated.
RasterOps drivers are hard to find. If any reader has copies, please contact me and I'll sort out distribution.
in version 3.2 and 3.3, go here to the Knighttech archives.
I have a v3.3.1 tho it might be the same as the 3.3 at MDM above.
