Well, lots of progress yesterday - I managed to read the entirety of the old Tek hard drive on a modern PC using dd and an Adaptec controller - no idea why the controller should make a difference (my other PC SCSI card doesn't like the drive, and nor does the Tek's own controller) Better still, I dumped the raw disk image onto another drive and put that into the Tek, fully expecting it not to work - but it did! A big thanks to those on the list that offered advice - looks like I might be able to revive this thing :) (see my separate posting about filesystem checks) cheers Jules ps. the ROM-based diags reckon there's 64MB of memory in this thing and 16MB of framebuffer - I'm not ready to believe that yet, but it'd be nice :-) --
