Talk:Weitek

From Wikipedia, the free encyclopedia

A query over the comment that weitek floating point coprocessors were single precision only: certainly not true in the 1167 (for the 386), and presumably not true for later compatible successors. There was some weirdness in the instruction set (for instance subtract instruction was a=b-a where other two address machines have a=a-b). But it did both single and double precision. I'm pretty sure this was also true for the FPs weitek did for high end SUN 3s about the same time.

[edit] Laser printers

I had an old Qume CrystalPrint "laser" printer that had two different Weitek chips on its mainboard. Instead of a laser, the CrystalPrint series had a long LCD shutter panel directly between a halogen lamp and the OPC drum, with a single LCD element for each dot in the line.
