Not really. More like bit banging RS232, but that required carefully calculating the number of bus cycles spent in the loop. The calculations actually were very easy on the CDP1802. Most instructions needed only two bus cycles, some branches and NOP needed three. I would have used NOP only if I needed an odd number of bus cycles. Back then we used to run our terminals at conservative 300 baud, but recently we have rewritten that code to go to 1200 baud without changing the traditional clock frequency of 1.76 MHz and if you can run your computer at 5 MHz or even 6.4 MHz, 9600 baud or even more should be possible.

I have decided to leave my old computer at 1.76 MHz, but I have a CDP1802 BCE here, which runs at 5 MHz at 5V. Fast enough memory is no question anymore and if I forget about the old graphics chip (it limited the clock to 1.76 MHz) I can easily build a new one. I want to start with the processor board, which will have no I/O of its own, so bit banged RS232 will be really helpful to get this tpo work.
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.
