I will. Here's how much we're missing: ru.wikipedia - clones

Some of them are very obscure and may not be original designs, just generic Taiwanese beige boxes.

Sorry, my bad, that's a native-speaker joke, not a command smile

"Send in the clowns" is a famous song.

Nice work. It's amusing to see a random English language stop sign on a Soviet-era machine that's otherwise in Cyrillic smile

poisk1: hooked up cassette input and parts of the keyboard, here it tries to load BASIC from tape (and ultimately fails).



Also, the mc1502 does not boot from disk now -- I think the 'reset PC by 1' hack in pc_state::mc1502_wd17xx_drq_r is no longer working.

There's no reason it shouldn't work, unless it needs to be "reset PC by 2" now or something smile
