Looking for info on old SuperMac video board

(This is a follow-up to an earlier posting, but with some corrections
and further information.)

I recently acquired an old Macintosh II. In it was an older SuperMac
video board. Based on the pictures on Radius' web site, I have concluded
that this is a Spectrum/8 (original), Part # STD9411, Assy #
1002689-0001.

The label on the ROM reads:

                SUPERMAC TECH
                SPECTRUM D6
                1002690-B 1986

According to Newer`s SlotInfo program, The card revision is 1.0B9 and
has a part number of VGB-1.

Per Radius' FAQ, I have tried holding down the OPTION key while booting,
but
never got the "round robin" video mode selection. I have also tried
running SuperVideo 2.7.5 which tells me I must have ROM version 1.9 or
later in order to select a monitor.

Currently, the card seems to be "stuck" in what I assume is the default
mode of 1016x768.

So, does anyone have:

1) Info on how to get the card into other modes (pref 640x480 for now).
2) Setup software for this old a card.
3) Any info on support monitor resolutions and frequencies?

Thanks in advance...
