I haven't been able to contact John for over a month now by
email or any of the phone numbers. I haven't checked to see
if he's been posting anything on his RVHE support page.
I assume he's buried on trying to keep his RVHE company
going.

The Unisys SCAMP package conhttp://freepatentsonline.com/5113500.html
appears to be a patent for it.
A local scrapper auctioned a VAX3500 system this last week and the
winner asked only for the boards. They were about to junk the
cabinet, so I asked them to hold off over the weekend so that I could
inquire if there was any interest in parts. The card cage, power
supplies, the disk interface cabling, and plastic are available. If
there is any interest please let me know this weekend.

Ok, first, the "MS-DOS" that you want to use is "MS-DOS 7", "extracted" from
Windows 98SE. This is easy, just find a 98SE system and format a bootable
floppy. The utilities are in C:\Windows\Command of the 98SE system.
[additional MS-DOS utilities are on the Windows 98SE CD]. This version of
MS-DOS ***WILL*** recognize FAT32 partitions. Also, there was an update to
FDISK in May of 2000, you want to get that, it's available from the
Microsoft web site. It will recognize drives up to 137 gigabytes.
There is no easy way to manually install, but you can boot from a DOS
bootable CD and run SYS from that. After you make the "MS-DOS 7" floppy
(above), use that floppy as an "image" in making a bootable CD.
That should get you where you want to go.
[Note, the full set of DOS utilities won't fit on a 1.44MB floppy, so be
sure to put them on the CD so that you have a place to copy them from.]

Assuming you're referring to the standard 72 pin SIMM, my best source
is the roughly 6 gallon bucket out in the shop that is almost full of
nothing but 4mb/8mb sticks. No doubt that some of it is EDO and there
is parity as well as non-parity. I got tired of sorting anything less
than 16 mb and the bucket does the trick.

There are some terminal protocols that use a daisy-chained RS232. The
Burroughs/Unisys Poll Select protocol is one. It relies on the handshake
lines in standard RS232.
