Vector Graphics PROM at auction (not mine)

[RickNel]

Noticed a couple of interesting boards being offered by the same seller on eBay at the moment, at very reasonable starting price:

One is a Compupro 128k SRAM

The other I am curious about - VectorGraphics PROM/RAM board with a ROM monitor installed.

Is anyone familiar with the VG ROM monitor?

(Of course, it's always possible the seller is a member of this forum)

I bought the Vector Graphic Inc. PROM/RAM board.
After over 6 weeks of traveling from the US to germany, it arrived today.
The V1MON V2.0 seems to be complete and is placed in 4 1702A EPROMs.
It starts on 0C000H.
Attached is the EPROM hexfile and a first disassembling.

You beat me to it, Mike!

I correct it at once.
Anyone has a complete manual for the board?
There is only a schematic in the "THE S-100 BUS HANDBOOK" from Dave Bursky.

No problemo, Frank; even sites that should know better make that mistake...

Anyone has a complete manual for the board?

Most info is about the later -III version, but I can ask on the VG user group.

Didn't mean to step on the cat's tail here . Just quoted the seller's ebay description

Anyway, thanks Frank for the susbtantive response. The S100 crowd is shrinking with the passage of time, judging by activity online.

Nah, we're all just the strong silent types who never have to ask for help on line;-)

Actually, Andrew and John's N8VEM new S100 cards seem to have created a fair bit of interest.

Hello Mike,
Are you find time, to ask the VG user group in the meantime for the manual?

Yes I did, Frank, but unfortunately the only reply so far was for the -III version using 2704/2708s and 2114s, which is already on the web in several places; I believe yours is the -I version. I'll ask again, but it doesn't look good...
