It's amazing to think that this device was produced several years after the class simple casio watch we all know.
Same functionality more or less, probably a fraction of the weight and cost.
I'd attribute the difference to how military/government projects pan out and not necessarily to the less advanced soviet IC abilities. There are many similar examples in western military equipment.
- dfox 7y agoAssuming this thing was designed in early 80's (which it probably was given the LQ470-like DIL 7segment LED displays) there certainly was soviet made NMOS ASIC that implemented most of the functionality in single package. But similarly to contemporary western counterparts it required bunch of funky supply voltages (albeit the supply rails used by soviet alarm clock ASICs are nowhere near the supply funkiness of Sanyo's essentially AC powered alarm clock ASICs) and were nowhere reliable enough to be used in space.
- blattimwind 7y agoThe LED display could have been an upgrade on an older design. I assume Soyuz always had a clock.
