Title: 8052AH-BASIC
Post by: Chris Savage on Mar 06, 2025, 12:37 PM
I didn't wants to hijack the Picomite thread (https://savagechats.com/index.php?topic=321.0), but I was curious if anyone ever used the 8052AH-BASIC? It was basically (pun intended) an 8051 / 8052 MCU with a built-in BASIC interpreter. Pretty sure I got one of these from BG Micro back in the day and if memory serves, you communicated with it over a serial terminal and you could connect a standard parallel SRAM (62xx) to give it memory. I seem to recall it had a multiplexed address / data bus externally? Anyway, I just wondered if anyone ever used one of these. Fond memories for sure, but then I really got into the Z80 after and just never went back.

I also purchased one several years ago, but never actually did anything with it.  :( One of these days, I need to fix that.

Jan Axelson has a great book on that BASIC-52 chip, and building it into a full-blown computer. It comes complete with experiments and add-ons. You may remember Steve Ciarcia's great book on the Z-80 (http://retro.hansotten.nl/uploads/z80/BuildYourOwnZ80.pdf), this is the BASIC-52 equivalent of that.

http://janaxelson.com/microcib.htm - you can download a PDF of Jan's book on the BASIC-52 for free.  ;D I have gone through that book many times.

I downloaded both PDF files. Pretty sure I had them in the past, but of course, having lost everything, it's nice to get some of it back again.
