80288

[Marrr]

So I saw this mysterious "80288" chip mentioned in a few places, unfortunately, none of them trustworthy...
Some claim it's a CPU, like 80286, only with 8-bit data bus.
Others claim it's some support chip allowing for 80286 to utilize 8-bit peripherals.
Where's the truth?

No such beast, as far as I know.

Perhaps the confusion is with the 82288, the bus controller for the 80286, or the 8288, the controller for the 8086/88.

Had there been an 80288 CPU, it would have sold like hotcakes as part of XT upgrade kits.

Intel was even slow to introduce the 80188 after the 80186.

OK, must be just a typo from "82288" then. Thanks.
