No kidding! I've got a 3rd party framebuffer for
my PDP-11/73, but
have never gotten it working, in part because I'm not sure what it
would take to hook up a monitor or even what type monitor would be
needed. In my case I've got drivers for RSX-11M, but they existed
for RT-11, and maybe other OS's.
Interesting... I have a Qbus framebuffer, too. I got it from my old
boss from a project where we built a QA training station for an
ultrasonic inspector. My (MACRO-11) code would slice a portion of a
large (multi-megabyte) data file and display just the desired
component (out of a tray of dozens) on the screen at
1000-pixels-per-inch resolution on a 512x512 screen. It happened that
we were manupulating grey scale data, but the framebuffer would do
color. The card has three odd LIMO-like connectors for
RGB-sync-on-green and that's it. I have one cable (for the green
channel, naturally).
I have *no* idea if there are drivers for anything aside from RT-11,
since that's what I was given for the project. I still have a few
listings, and I _may_ have an RL01 and/or RL02 pack with source code.
I'd be interestded to see pictures of your framebuffer. Mine is
accessible, but not here, so if desired, I could do the same.
