Somehow during the migration I managed to loose the OSI Model 300 trainer page.
Restored and with some additions!
Have a KIM-1 with faulty 6530? Look here for replacement with 6532 and some.
The DOS65 information is now complete. Last year I did document most of the system. And now I scanned the large pile of paper with manuals and source listings that were waiting to be added. Source listings of ROM, the Operating system and the Monitor and other documents. Most are in English! Enjoy!
For many years this site had a forum. It was PHPBB based, an older version.
Not much traffic, mostly news from me (which is now also here) and some posts already added to the pages of the site.
Thank you for the contributions and the Contact page is always available for your questions and contributions!
I have added the excellent html formatted manuals by Erik van den Broek to the KIM-1 Manuals page.
Groepaz from the VICE emulator team and the C64 demo group Hitmen just released an updated PDF of 6502 illegal or perhaps more accurately called unintentional opcodes.
I would say this document and the use of illegals are for advanced programmers but they can come in very handy for generating smaller or faster code at times.
Some illegal opcodes can be unstable on certain chips
NMOS 6510 Unintended Opcodes no more secrets (v0.91 – 24/12/16)
San Bergmans has released SB-Assembler 3
Now written in Python 3, runs on Windows, Linux, Max OS.
On its way from China, the R65C24. A dropin for a PIA, with a timer.
