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.

All information on the R65 and the emulator of this computer on the github archive of Rene Richarz, a work in progress!
Including sources and full documentation.

Original Job computer built 1977-1979
The R65 computer has been built 1977-1979 by Rene Richarztogether with Rudolf Baumann, who has built his own JOB computer at the same time with similar hardware. The picture above shows the open JOB computer. The original R65 computer has not survived. The floppy disks have also not survived.

Hardware specifications of the original R65 Computer:
– 6502 8-bit microprocessor
– 1 MHz clock speed
– 17 kByte, 33 kByte, 49 kByte RAM (expanded 2 times between 1977 an 1979)
– 2 kByte graphics RAM
– 10 kByte ROM
– 40 x 16 char monochrome display
– 224 x 118 dot monochrome graphics display (switchable with char display)
– 2 floppy disk drives. Formatted capacity 199680 bytes each.
– Interfaces: Teletype, RS232, parallel printer, audio tape, golf-ball typewriter, tv

He updated his archive on github with a PCB for a low cost variant.

The case has a small cutout around the top edges as the original.

The button has some ribbles as the original has.

Eduardo Casino added the FDC support. Now not only the SD Shield but also the upd765 based FDC support allows to run CP/M-65 and the native CODOS for KIM-1 operating systems.

One of the cases you saw quite often was this case. It came with one of my KIM-1’s. Small, simple and effective

A perfect solution for an unexpanded KIM-1. Quite popular in education. Add a power supply and you can start using it without exposing the electronics. The LED display was behind a red plexiglas cover, so that improves readability.

Gerben Voort acquired a 6502 system and made photos of the system. A backplane, the BEM bus, a 6502 based CPU card, a double VIA card, a battery backed up memory card.
