tu58 carts for 730 on ebay

These are the very same diagnostics I wrote about on this list just a short while ago when discussing poor man's alternatives to AXE for validating new VAX implementations until we can raise enough manpower and firepower to storm into HP headquarters and seize AXE at gunpoint. These diags are not specific to 730, I read about them first in an 8200 manual and they test for correct operation of standard VAX instructions. I understand from the discussion on this list that their coverage is nowhere near as complete as AXE, but it's still a more complete test than just seeing my new VAX boot 4.3BSD-Quasijarus. (For example, UNIX makes absolutely no use of executive or supervisor modes, just kernel and user.) The next challenge will be reading the TU58s. I have the TU58 mechanical units, but not the controller board (the board that talks serial on one side and drives the head coils on the other). So I'll need to find a controller board first before I can read them. When I do read them, I'll post the block images on my FTP site. MS
