Re: Z180 (was: Captain Video)

TI-86 is a Z80 with 128mb of memory, so likely one of the processors you guys are talking about, too. Display on them is essentially the same as the TRS-80 computers, except maybe for graphics. There were ways to load progams onto it and run them, but by the time I found out about them my TI-86 was having display problems. It was the last TI I bought for myself as they just abandoned it. While mine was still pretty new! The rats. Of course I'n not the only one TI did that to.?

Yes. Besides the P112, there have in fact been many follow-in
enhancements to the Z80 family. The current TI-84 calculators still use
them today.

Sort of... 8- vs. 16-bit is a blurry line. It's hard to call the 8088 a
16-bit CPU, except in marketing. At the same clock speed, the Z80 easily
out-performed it. The Z180 was even faster, and had a bigger address
space as well.
> 8088 was Totally program (binary) incompatable. But it was a thing.
Yep. Marketing over engineering.
