Elektor Junior pages updated

After several years so much new and correct information has been coming in!

While I was studying the Comal interpreter, I want to port it to the KIM-1, I realised the Elektor pages required some updating and reorganising.
I could not find easy what I needed: circuits and source listings. So I extracted the circuits from the articles and checked the various listings with the ROMs I had in my archive.
Also the sources that appeared the last years were checked, adapted and the binaries compared with the hex dumps. Some surprises, many faults and not with the correct names.
The ESS numbers are now attached to the ROMs.

Now you can have all the essential Elektor Junior information from base to full system with checked ROMs, with sources, step by step.

The complete archive of articles and books is also updated, especially the English articles are as complete as possible.

Have a look at the Elektor Junior pages!

With thanks to the many persons and fora that helped me to collect the information.

Italian Junior articles archive

I found scans of the Italian Elektor magazine 1-62 on the web! Here you find the relevant Junior/6502/Z80 articles from those magazines in a (large!) PDF archive.

Focal runs on KIM-1 Simulator

KIM-1 Simulator version 1.1.6 has been published. Get it here.

It now supports Focal-V3D 12-AUG-77 (the Aresco version) from the KIM-1 Software page, see here.

Updates to the Simulator are a working echo suppression (see here for background). Available to any program.

For Focal V3D a setting has to be made in the Settings, to allow Focal to do its magic in the input routine.

By working on Focal I did add comments to the disassembly of what I found. You will find the original by Paul R. Santa-Marie and my partly commented version in the archive.

Testing the 6530-002 RRIOT with a KIM-1

This article is written by Jeff M. Nay, about his experiments to restore a KIM-1 to working order. The challenge was to address the second 6530-002 in this setup at another address then the onboard 6530-002 RRIOT.The experiment was a success, the 6530-002 is indeed in a bad state, the ROM is corrupt and it had to be replaced.The KIM-1, from a friend, was in a bad state. The repair was a success also. He was able to get this old KIM-1 working again, after only having to replace, the 6502 CPU, the 6530-002 RRIOT Chip with a Corsham 6530 Replacement board, all 8 Memory Chips and the U17 7406 inverter.

KIM-1 and TIM updates

I have added the following to the KIM-2 KIM-3-KIM-4 KIM-5 KIM-6 pages:

– brochure with photos and descriptions and pricelist KIM System Products
– photos of KIM-2 and KIM4 with KIM-4 motherboard with KIM-3b, KIM-5, KIM-6
– brochure TIM System Development Aid with pricelist

The brochure of KIM-5 etc is from Commodore, the KIM-2 RAM was already dropped for a higher capacity KIM-3B. The KIM-5 was still mentioned as product. Alas I have never seen or heard of a KIM-5 in the hands of a user. So the ROMS are lost alas.

Lost pages of Andrew Jacobs

The late Andrew Jacobs set up a web site with relevant 6502 information. It is lost now.

This site is reproduced here. Scripts and links are removed, it is clean code now.

Also have a look at his github archive, it is still up.

macOS compiled version of KIM-1 Simulator

Thanks to user hobo of https://groups.google.com/g/pal6502 a macOS compiled app is now included.

KIM-1 Circuit Diagram high resolution poster, cleaned up again

A couple of weeks I published the KIM-1 Circuit Diagram in high resolution, cleaned up by Joshy of Forum64.

Since then I saw people print the poster, and I did have myself made a mouse mat and a poster in KIM-1 format.

To let the printing company do its work I made two new versions of the poster:

  • KIM-1 Circuit Diagram in high resolution, cleaned up by Joshy of Forum64 and cleaned up again by me (year 1975, some artefacts
  • KIM-1 Circuit Diagram in high resolution, cleaned up with wide borders (for canvas prints)

Look at the KIM-1 Manuals page for those new, large files images.
