KIM-1 Simulator V2.3.0

Posted on by

Again Eduardo Casino has enhanced the KIM-1 Simulator V2.3.0 after adding the K-1103 and Corsham SD-Shield with CODOS and CP/M-65 operating system in V2.0:

Version 2.2 and 2.3:

– The Console has now a complete VT100 emulation with color and the DEC Special Character set
– The console supports cut and paste text with the mouse (very handy to dump a papertape into the KIM-1)
– The K-1008 Visable Memory emulation has become blazing fast
– All settings are saved between sessions

KIM-3B added to my collection

Posted on by

A KIM-3B is a 8K bytes memory expansion made by MOS Technology (already part of Commodore then) for the KIM-4 motherboard.

I recently acquired a good looking KIM-3B myself. Nothing new, all is already known about it. Now with photos made by myself!

TERC KIM-1 Interface set

Posted on by

A recent acquisition, the TERC (Technical Education Research Centers) KIM-1 Interface set. An educational tool to work with the KIM-1 from the 80ties.

The KIM-1 Interface permits easy access to the input/output ports on the KIM-1. Other connections such as power, ground, tape recorder input and input and output are accessible by solderless connectors.

PROTON KB-2 keyboard

Posted on by

Walter van Waard found a keyboard made by PROTON, a Dutch company from the 80ties that produced many 6502 and Z80 based computers and peripherals.


It looks like an ASCII keyboard with more function keys (F1-F8) than usual.
Production date is probably not before 1984 since the ICs have date codes from 1983.
No documentation or description is known.

On the PCB you see:

  1. The MC6802, an 6800 with 128bytes RAM and an internal clock oscillator
  2. The 74LS138 glue logic IC
  3. A 74LS14 with a potmeter and capacitor
  4. A MC145028 dual flip flop with some resistors and capacitors, perhaps a clock oscillator
  5. 2x MC6821 PIAs to sense the keyboard matrix and presumably serial I/O via bit-banging.
  6. A K1/K2 connector, where three wires are connected. One wire goes to a pin of the 6821 PIA, the other two are power supply 5V and ground.
    When a key is pressed, the 6821 pin goes to 0V, so it looks like a (poor mens) rs232 signal.
  7. A keyboard matrix with many extra keys (F1-F8, cursor keys, CHAR Insert/Delete, numerical keyboard.

Jolt replica with ‘time period correct’ old parts

Posted on by

Eduardo Casino has done a great job replicating the PCB of the Jolt. And he proved the PCB was OK by building a Jolt and setting it to work.

I have populated a replica PCB with as much as I have in my junk boxes ‘time period correct’ parts. It does look good compared to photos of the original Jolt.
I am waiting for a ‘white’ 6502 to arrive, the purple one is already period correct.
This Jolt is meant to be a ‘museum’ part and will end up above my desk next to an original SuperJolt.
The next Jolt I will build will be a functional one with ‘black’ ICs and less attention to perfection.
