The mvme68k port definitely won't run on the ISI systems. Having both an MVME-147 and 4 ISI Optimums, I speak from experience :-). The 68020 boards don't have Motorola MMUs, but rather something that ISI apparently came up with, although, from the documentation I have on it, it seems _kind of_ similar... I'm quite interested in getting NetBSD running on my systems (all the VME-68020 variety, one a V/16, the others V/8s...) since they're currently running a _really_ ancient 4.2BSD port. I started ... but NetBSD/hp300 is sucking up a lot of my time. I have stuff like preliminary boot code, that kind of thing. There are several snags with this box - for example, from all indication, the PROMs (which report themselves as being the 4.2 boot) seem to load the kernel directly from the filesystem. I.e. there is not external boot code. It's probably reasonable to assume that the PROMs don't understand modern 4.4 filesystems. (Sun's boot code doesn't, why would these?) Well, that's one of them anyway. Thankfully, hardware available for these things seems pretty standard. For example, my systems have AMD LANCE and Intel ethernet controllers, and these strange, odd SCSI controllers that only seem to understand 4 targets (they're connected to the MFM and ESDI disks via Adaptec bridges, similar to the Emulex MD/21s). The SCSI initiator is an NCR 53c85 with a 16-bit Zilog 8200-series CPU sitting in front of it. I can only assume that the Zilog is acting as some sort of DMAC. I should read the documentation again... The coolest thing about these boxes (besides their being Motorola :-) is the optional VME serial boards ... I have 8 of these boards each with 4 Signetics 2681 DUARTs, and break-out boxes...that's a lot of serial ports! :-) -- Jason R.
