IIRC they were all written on PDP and cross-compiled to Z80/8080 and later the 8086. I heard Billy wrote his BASIC interpreter dialed into a PDP from a motel room in Arizona while living off $100K his famous dad gave him to “get lost” (if the motel was owned by Burt Rutan, that would be too funny.) Later Sun workstations were used to launch Macs, Amigas and AtariST while a traitor was leaving DEC/PDP/VAX to setup shop at MS and create NT which destroyed the tech economy until it was rebuilt by a child who found Andy Tanenbaum’s book and some free sourcecode from a communist at MIT. The free tech allowed the dot com bubble and when that blew and the elders were generally forced into retirement, Amazon saw an opportunity to do the heavy lifting for the poor-wage children left behind, leaving the retired elders to make JavaScript based PDP emulators. It should all be unfsck’d by 2026 tho (that’s when the first wave of formally trained Computer Scientists after the nuclear winter ended will hit 20 years and, with their grey beards and pear shapes, be mentoring several generations behind them…same as it ever was.)
