Are there any special considerations required for interfacing modern microcontrollers with older NMOS chips?
@gsuberland @th what Graham says. He beat me to it :)
@nintegge @th one other thing I just thought of is that these old devices have zero built in ESD protection, so they should be treated with care. most modern IC packages come with TVS clamps built in, as do some MOSFETs, and they're good to a handful of kV just to offer some modicum of protection against smaller discharge events. we mostly take that for granted these days.
@gsuberland @nintegge thanks for the suggestions! I'm hoping they work well enough to recreate the Cyclops digital camera.
@th @gsuberland @nintegge Do you have links on how the X-Y scan outputs for the scope on that works? I've patched my scope display into my Teams meetings webcam input and it'd be really cool to use opencv to grab a live webcam image, do whatever the cyclops transform is, then feed the X-Y out to the scope via a DAC pair.
@bikerglen @gsuberland @nintegge the camera and de-caped SRAM chip image sensor is explained in the Popular Mechanics 1975 issue along with schematics to build your own: https://archive.org/details/197502PopularElectronics
@th Thanks! Reading it now!
@th What I have read about those old Soviet chips, drive them slow and experiment with pull up/down resistors. Let me know what you find I've a small collection of Soviet chips.
@th main difference is probably drive strength and rise time, so maybe stick a 22R in series with logic lines just to be super safe, but otherwise I can't think of anything.
