A follow up to a previous post about GG’s Homebrew Z80 Computer. He’s implemented a BASIC interpreter using the AM9511 math processor. Oh, and did I mention the whole thing fits into 3Kb of ROM? He writes:
Hi, I finally wrote a Basic interpreter language for my Z80/AM95 8-bit NANO COMPUTER in order to easily program it.
I called it “8BASIC” because everything must clearly fit the 8 digit LED display.
The video shows all commands and statements, plus two famous benchmarks vs. contemporaneous 1970’s-80’s computers.
Due to the strong mathematical support of the AM9511 math processor, the BASIC interpreter runs reasonably fast for a 2.5 MHz machine, offering seven significant digits floating-point arithmetic.
