UMC (Uniwersalna Maszyna Cyfrowa - Polish for Universal Digital Machine) is a family of computers produced by Elwro from 1962.
It consisted of vacuum-tube based UMC-1 and transistor-based UMC-10. UMC computers in 1964 operated using negabinary (-2 base) numeral system invented by prof. Zdzisław Pawlak.
However, the uncertainty about US tariffs has weighed on the chipmaker’s business visibility for the second half of this year, UMC chief financial officer Liu Chi-tung (劉啟東) said at an online earnings conference yesterday.
