Interesting fact: hp3000 is an example of very few mainframe/mini computers based on stack architecture instead of registers:) I'm currently writing assembler

I'm currently writing assembler for my own virtual cpu hehe. Stack based of course
- tdeck 1y agoI think the Burroughs machines also had a stack-based architecture https://www.hoa.org/blog/jack-allweiss/evolution-of-burroughs-stack-architecture-mainframe-computers/# https://www.hoa.org/blog/jack-allweiss/evolution-of-burrough...
- arethuza 1y agoI had to use a Burroughs mainframe for development during the first year of my CS course in 1983 - might have been interesting hardware but the user experience was ghastly - some awful thing called CANDE = although I did get a laugh out of all of the references to the MCP. In retrospect I do wonder if they did that so that when we moved to Unix machines later in the course we'd really appreciate them!
- satiated_grue 1y agoMCP is still available from Unisys, which was formed by the "merger" of Burroughs and Sperry Univac. It was first released in 1961 - is there any other software, particularly an OS, still in production after that long? https://en.wikipedia.org/wiki/Burroughs_MCP https://en.wikipedia.org/wiki/Burroughs_MCP
- nathan_douglas 1y agoI did a similar project as an independent study for my CS degree. It was a ton of fun! I haven't tried it but I think you can then write a Forth for it very simply too.
