But maybe we should solve that one - The poor guy 8749 _really_ was an 8-bit processor. And not the worst that Intel ever built.The successors are still around in the embedded industry.Some mildly off-topic info: - 8748/49 was THE processor of choice for PC keyboards. Before USB, **all** of them used 8748 or 8749 microcontrollers, even in die form. - Up to the 386, all PCs had one of them in Keyboard input - And after the 386, much of them had it too, but integrated in bigger ASICs
But in those it wasn't asked to do more than keyboard communication. It didn't have to handle sound and RS232 data at speeds far beyond a human could type, whilst still reading the keyboard. The poor thing was just overloaded.
