I have several 501-1006 Multibus SCSI host adapters but ATM no running
Sun machines to format a drive on. I guess I should fix one of them up
It's been a long time but I seem to remember I could dd disk images
between SCSI disks but not SMD and ESDI drives due to drive parameters
being on disk. I barely remember installing the OS 3.X and 4.X but I do
remember rebuilding the kernel to reconfigure or add devices.
Speaking of the MB SCSI HA, does anyone have a part number label still
on the center most 16R4 PAL next to U300. I have all the other PALs
labeled but that one.

Thanks, I found your site early on in the search to refresh my long
paged out memories. What you've posted was useful.
Fearing the loss of something important reusing any of my existing
drives I've got a SCSI2SD on order.
