I'd contact ICD or Supra and find out whether there boards >support the ADAPTEC 4525. I do know for a fact that they support 4000/4070. I use the adaptec 4525 controller. It has the advantage that there is a jumper which allows it to mimic the 4000 controller to some extend. This jumper will allow it to work with most of the standard ST harddisk drivers, partition software etc. In order to get this to work you'll need something to go from ACSI (on the DMA port) to SCSI. I use a BMS 200 from Berkeley microsystems for that. They also sell the 4525, and are quite helpful. As stated before ICD and Supra also offer ACSI<->SCSi adaptors, and maybe also 4525 adaptors. I've never done business with them. I believe a BMS 200 with adaptec 4520 (2 boards) was something between $250,-- and $ 300,--. Comes with the cabling. You'll have to supply the power supply, disk and housing, and to assemble the stuff. Not too difficult. Good luck! -- Frans Meulenbroeks (meulenbr@prl.philips.nl) Centre for Software Technology
