Spread the word: November 25 is #ChuckPeddleDay — celebrating the engineer behind the legendary MOS 6502 processor, the heart of so many home computers and game consoles of the 80s. 💾🕹️

If you own a machine powered by a 6502, fire it up on that day and share a photo with the hashtag #ChuckPeddleDay

It’s Chuck Peddle’s birthday on November 25th, so get your KIM-1 or other #6502 system ready for a big Show and Tell in his honour.

How to build a KIM uno on your own?
Order the PCBs from pcbway, order all electronic parts from Aliexpress, program the Arduino, solder everything together, print the case. ( I ordered parts for some more builds - christmas is nigh) #kim1 #kim-1 #65o2

90% of my recent „new“ BBS users were not able so send an application email.
- WTF ?
They stopped the registration process instead of sending an ‚Hi‘
There are no other requirements.
I‘m a bit confused 😟

Today I dug out my KIM-1 to test @zoggins.bsky.social I/O board.
Only to find out there is something wrong with the RAM.
sigh. 😔

This is my #BBS Hackerforce running on a RPi. You also see the small LoRa device for the #meshbbs also running on that Pi.

A dead KIM-1? Fix it!
In October 2025 I have revised the page about the KIM-1 diagnostic board with sources of the tests in MOS Technology standard assembler syntax . The EPROM can now be build and modified with modern tools.

The KIM-1 I/O Board by @retro-spy.com arrived today. Now I have a secure way to use my original KIM with a modern PSU. Remember: November 25th is Chuck-Peddle-Day - time to turn on your KIMs and celebrate

#Meshtastic #bbs #meshbbs is setted up. Is it a good idea to blast it out via MQTT? lets see.

Yay! The main #PCB for my MOS #KIM-1 replica arrived today from #JLCPCB! The sub-boards seem to fit. Bringup will take awhile since there's a gross chip-pin-numbering error on one of the smaller boards and I'll have to re-fab it. But I'll be able to partially assemble it and test a few things.

Everybody knows that the dice are loaded
Everybody rolls with their fingers crossed
Everybody knows the war is over
Everybody knows the good guys lost
Everybody knows the fight was fixed
The poor stay poor, the rich get rich
That's how it goes
Everybody knows
