I was donated PMAG-JA TC option card, and TX is one of supported
device by DECstation as dev/tc/tfb.c.
TX is two-framebuffer-in-a-single device, they can be manipulated
independently via distinct address space. Two images are composed by
1bpp 'layer screen', like as having a hole showing true color live
video image on standard 8bpp X window world. TX can be used as a
video frame capture card too, and ULTRIX provided a special IOCTL for
I suppose the Rasterop chip might be used by some of sBus framebuffer
