It would be really difficult to find a accelerator wich would work with GVP HD8+, because it uses DMA.

A530T yummy ... Wouldn't be without mine. Anyhoo, biggest problem with the GVP sidecars is the power supplies. I have quite a few and the capacitors inside just ooze and die. So its worth checking if you have an original PSU. Also check the connector cus they can be a problem inserting and I've had them with damaged connectors, especially at the ends. And also worth getting a ground if you don't have one fitted. Poor connectivity can cause consiiderable issues and power.

AHA! the Supra Turbo28 runs fine with the GVP HD8+, but it limits the ram to 4meg as it needs some of the addressing for its sram cache.
sure it's not 030 fast, but it's a 4x uptick on stock... that was my config - still able to hold it's own vs all my friends who got A1200's and then fast ram upgrades...

Hi,

I used the HD8+ and M-Tec030 with 4MB 32bit-ram (no DMA, no Autoconfig) - long time ago.  :)

Try the following:

DMA: set DMA-Mask in RDB to 4FFFFE for every partition - DMA into 16bit-ram only and HD8+ should work with other turboboards
