I've made some photos and even managed to lift the lcd a bit... Can you tell more this way? Note the 12MHz crystal... Might that be a hint?  ...

I've done little googling. And it might, just might be a **z51f3220**. I am not sure... Any luck with this MCU?

It seems there are people on internet having same problem... I guess there's no lightweight cheali alternative targeting these devices yet?

Thanks for interresting insights! > The parity bit is absolutely necessary. I've checked again and actually there's a code for parity bit, so this should be ok. I thought that...

Eh. Checked again and the write ends like this: ```C // stop bit gohi(_ps2data); delayMicroseconds(CLKHALF); golo(_ps2clk); delayMicroseconds(CLKFULL); gohi(_ps2clk); delayMicroseconds(CLKHALF); //20 us delayMicroseconds(50); ``` Which means, there actually is 70 us...

I've changed that last line to `delayMicroseconds(500);` and now it seems to work properly. But i've realized that the keyboard is not working until i plug real ps2 keyboard to...
