> While it lacked the hardware scrolling
That's the biggest "what if" omission of the TMS9918 for me - I wonder how the 8-bit landscape would have evolved if it had even minimal support like the scroll registers of the VIC-II...
I'm more shocked that the MSX2 graphics chip (before the plus revision) had a "screen adjust" register but no border blanking for horizontal scrolling. Massive miss there, much worse than the lack of scrolling on the original TMS9918 which was developed at a time where scrolling wasn't all that common.
