Zx81 has 1KB. The clones got more memory. TK82C has 2K. The one I had was 16KB. There was even some with 32KB.
Interesting days
My first computer was a Sinclair ZX81 clone, running on a Zilog Z80A processor, with 16KiB of RAM (and 8KiB of ROM).
Do projects really just blindly change version decencies without regression testing and push to production?
A lot do, yeah. Maybe even most.
It is the culture of "auto update to keep it secure" fostered by Microsoft (in particular, but others as well). AV companies and (ironically) security companies also do it.
It is, as far as I'm concerned, not much better than security through obscurity.
Very few people still have testing environments where they test every and all updates.
Thank you for your honesty. It is really rare these days.
When the bosses talk about improving productivity, they are never talking about themselves.
