The problem is the old architecture. I need I/O chips that signal incoming data by raising an interrupt and stay off the data bus until the processor comes and reads the data register. All microcontroller solutions I have seen had some trouble with that last part, as they could not tri-state their I/O pins and put the data on the bus when the read signal comes. Otherwise I would not mind using a microcontroller for the PS/2 ports.

Another option would be to use standard UARTs and use them to attach USB keyboard and mouse with a converter inbetween. Ugly, but it would work.

As for the serial EEPROMs: Bit banging has a long tradition on this particular computer, but it's quite slow. We used to bit bang RS232 to attach terminals. The old programs ran at 'safe' 300 baud, but with a little tweaking we already reached up to 2400 baud. At a slightly higher clock frequency 4800 baud have been reached and (without having tried it yet) 9600 baud may also be possible at the maximum clock frequency. A bit banged SPI or I2C interface would perform no better than that.
The language is JavaScript. that of Mordor, which I will not utter here

This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a f***ing golf cart.

"I don't know, extraterrestrial?"
"You mean like from space?"
"No, from Canada."

If software development were a circus, we would all be the clowns.
