Thorsten Leemhuis (acct. 1/4)Remember the #Hercules monochrome ISA graphics adapter?
I had one in the first PC I used – about ~37 years ago.
The driver for it was now removed from #Linux for Version 7.2: https://git.kernel.org/torvalds/c/37a91b995952a556a6eb90c31736ee773b86999c
nick@kernellogger Damnit that was my dream setup for a while there, you could do cool graphics mode shit on the main VGA card and still read the debugging output on the HGA.
(I don't quite remember how that worked now but anyway, that's why people loved them)
christian mock@nickzoic @kernellogger it worked because the video RAM was mapped at different addresses. Such a dual-screen setup was also used for AutoCAD, with a 19" monitor with some special graphics card (that could only do graphics) for CAD and the hercules for DOS and the AutoCAD CLI...
@cm @kernellogger oh that's right, whereas you couldnt have two VGA cards because they'd be at the same physical address.
The Apple 2 is still about the only computer that got this right.

@nickzoic @kernellogger ISTR there were VGA cards that could be jumpered (remember those?) to a different framebuffer address (and probably a different BIOS address, too), but I don't think I ever did that...
