I know it is off-topic here but I don't know where better to ask. For "education" I want to try to make a small project with a 8051 family chips (there is some DIY clock kit using AT89C2051 - I would like to reprogram it). AFAIK 8051 family is not supported by either Arduino IDE or Atmel Atudio 7.0 …

Hi !! Long time ago I've used Keil's IDE (µVision=C51) , evaluation version (2KB limited) with AT89C2051 chips (2KB Flash) First class C compiler for a chip not very C friendly..... Still available ? Maybe : https://www.instructables.com/8051-Programming-Using-Keil-UVision-IDE/ IAR Embedded wo…

Atmel USED to have a "AT89LP Developer Studio", but I don't see it anywhere on the Microchip site (in spite of the fact that Microchip has now acquired several companies with 8051-like product lines. Hmmph.) (This used the same SDCC compiler that others have mentioned.)
