This directory contains various DEC odds and ends: microcodes, ROM images, diags, VMS/Ultrix booters and bits, etc. The following items are currently available: pcs750.bin.V98 pcs750.bin 11/750 microcode patch file V98. pcs750.bin.V99 pcs750.bin 11/750 microcode patch file V99. This is the correct V99, not the broken one that came with 4.3-Tahoe and later BSD distributions. This is the one I recommend using. rabads.a.out Ultrix rabads program, a.out version for putting onto a UNIX filesystem and loading via UNIX boot. rabads.core Ultrix rabads program, pure core version for putting onto console media and loading via console commands.
