That's interesting. My first computer was a TI-99/4a, and I don't remember seeing stuff like BIOS listings in the documentation. I don't have any of that stuff anymore, so, I could be wrong.
- flohofwoe 5y agoThe ROM listings were usually "third party" efforts, for instance in Germany there was a fairly popular (among home computer enthusiasts) "xxx Intern" book series where most of the book consisted of the annotated ROM disassembly. For instance "CPC Intern": http://www.cpcwiki.eu/index.php/CPC464_Intern http://www.cpcwiki.eu/index.php/CPC464_Intern
- incanus77 5y agoNo, you're right. The TI-99 was notoriously closed and anti-hobbyist. It was my first as well, and I recently got my hands on one again (though a later, reduced-cost beige-case one). It's remarkable how opaque the system is. Contrast this with my Commodore 128 or TRS-80 Model 100, which ship with schematics, opcode info, etc. and had a healthy book ecosystem around them. I hit my limits with the relatively weak TI-BASIC, but having nowhere else to go (even with the technical "green manual"), I wonder what I would have gotten up to had there been more there like a built-in assembler. Then again, the thing did ship in 1979 initially and was the first home 16-bit machine (technically).
