I had a quick look at the Win32 BitBlt API and it seems to be quite similar. Can you remember how much work was actually involved in mapping the Smalltalk primitives to Win32?
- pinewurst 6y agoI probably shouldn't have described it quite like that. This was in the days of Windows 2 (1988 or so) and I was hacking PPS Smalltalk to support larger, non-VGA displays. I ran the VM in 386 protected mode, because it needed large memory, where it blt-ed to an upper memory frame buffer. This was sort of a "bounce buffer" which in turn was blt-ed onto a Windows canvas by my Windows app which also reflected input events up to the VM. Bill Gates was impressed when he saw a demo (or so I was told). Of course, he didn't realize the level of hackery involved to make it happen.
