According to the Sun Framebuffer FAQ, the TGX/TGX+
framebuffer is
quite universally programmable - some OBP Forth magic allows you to
select one of several possible dot clock frequencies, adjust front
porch/sync/back porch widths in multiples of pixel duration and so
on.
(Before anyone asks, this is all just idle
experimental
proof-of-concept stuff and not intended to work with any
off-the-shelf software. If all goes extremely well, it might turn
into a sort of SPARC-based videogame console somewhere in time, as
I'm looking for TV rate RGB output.)
And I'd be interested in making my 1600x1280-capable framebuffers do
1600x1200, so they can be used with designed-for-peecee (= inexpensive)
displays. (The one I care most about is a cg14, not a cg6, but IIRC
they are rather similar in how things like video modes get set.)
As I don't have a TGX/TGX+ in any of my easily
accessible machines,
You appear to be in Germany. I have lots of such SBus boards, and
would be happy to post one to you, but I don't know whether it would be
worth the hassle involved in getting it through borders - I'm in
Canada. If you want one, drop me a line - I don't recall whether
you've gotten mail to me in the past; if not, I recommend
mouse at
netbsd.org and mouse at openface.ca as well as
mouse at rodents.montreal.qc.ca.
I've already extracted some of the corresponding
FCode(attributes and
words from /iommu/sbus/cgthree) but it doesn't give me much of an
idea where to start yet. Has anybody been involved with that stuff
far enough to tell me - or just give me some pointers towards
figuring out - which lever does what?
Doesn't uncompiling the FCode give you a fair idea of what's involved
in setting up the video?
Psssst! Schon vom neuen GMX MultiMessenger geh?rt?
Der kann`s mit allen:

No thanks. It appears to be (a) entirely auf Deutsch, (b) binary-only,
and (c) offering nothing I particularly want.
