Here's our fifth monthly roundup - see also our
partial catalogue and our
profile page. Comments welcome on this thread!
2015-05-01 An obscure multi-user 6502 system: the es65 from Ernst Steiner of Vienna, a 1980 system which assigns a dedicated memory board to each user. Links within to other early systems and other aspects of multitasking on 6502.
2015-05-08 Deepmind applies AI to play Atari games (learning the goals of the game and learning to play it according to those goals.) We have two other examples too, from 2008 and 2013.
2015-05-15 The plug pig, aka "Das Steckschwein" - a project which started as a breadboarded CPU running a NOP-generator and became a grown up multi-PCB computer. As
seen before here on this forum. In this post we link to several videos and specific entries from the progress blog - should be helpful for those not German-speaking.
2015-05-22 A transistor level simulation of the Atari 2600, featuring a python simulation engine, from the original visual6502 team. We link to
Michael's talk all about the 6502 and to
Wladimir's novel visualisation.
2015-05-29 From 1975, the OSI 300 trainer for just $99 is quite the minimal 6502 system - just 128 bytes of RAM, no ROM, with LEDs and toggle switches to load, run, and debug. The circuit has been reverse-engineered, so there is now a clean version of the schematic and a breadboard re-implementation.
