So I'm not the only... -- surprise for me, too.

I'm too using this, mostly because I like it, got up with it, and it's better than those pixelled displays today. And who needs colours?
For me, it says (2.4.0-prerelease) I'd got a HGC with 8 kB of RAM.
This surely isn't true because under DOS some pgmz work problemless
which use the whole 64K of &hB0000 to &hBFFFF (when I deactivate the VGA
card), and even Turbo Debugger 1.0's dual-screen option works in both gfx and
text mode, with the other card as debugging display in text mode, no matter whether the PGM uses HGC or VGA as primary display.
I'm sorry I've got no correction, but prolly you could try to read-modify-write-read-write_original, and compare the read value with the written bzw. the original.
And - do we get a HGC gfx framebuffer hgc1fb? (Btw, the vga16fb must be called vga4fb - it uses 4 bit colour, not 16)
What about dual-screen X... (this is OT - I know)

(Sorry about my English) - mirabilos

Yes. I'm using it on my HGC to display graphics. It is called hgafb
(or so?) and included in 2.4.0.
