in an ancient SparcStation 10, i found (according to show-devs)
two cgeight framebuffers.
One of them is a two-sbus-sized card with connetors like newer ZX (leo)
but there are no SUN-Part numbers on it.
I did not open the pack of two PCBs to see what is printed on the chips,
but from the side view i can read "RasterOps" on one of the bigger
(and there are lots of Memory Modules standing on ther side).
Using a SUN-Monitor on the 13W3 Connector, i can install Solaris 2.7 BW.
Hacking /etc/dt/config/Xservers, i get truecolor (24 Bit), but this is
on the 40 MHz 64 MByte SS10 :-(
On this Card, there is a label "4504/10127".
On the PCB, i find "SBC-2B" "94V-0" "45-91" and "P.C.B 0003-0020 REV B2"
On a label on the upper side: "SERIAL # 00403 MDL. 4504"
The other card is single-sized, has a SubD-15-female connector (not the
a Label "4510/20120",
two-DIP-Switches and one Jumper,
three Osczillators 14.750 , 12.2727 , 30.2400 MHz
on the underside, a BT473 RAMDAC, two "DAC2400-0002",
a RAsterOps 1990 RGS14188 chip, "P.C.B. 0003-0032 REV. B1".
This Board also claims to be a cgeight.
I cannot test it since i do not know the pinout of the connector,
and the oszillators frequencies seem to not match SUn_monitor Standard.
So does anybody know what this cards are, weather i should use the
default drivers form SUN
or are there any faster driver because the boards have some processing
Many THanks for your patience,
any advice may help,
