Eduardo Casino has designed with modern tools, like Kicad and image software Inkscape a PCB for the KIM-1 which is as close as he could get to a Rev D.
Based upon images on the Revisions pages on this site.
On this forum64.de thread he published the design, and made all available on his github pages.
The PCB is an exact PCB replica of the KIM-1. It therefore requires 6530-002 and -003 RRIOTs, which are not available anymore (or use the Retrospy Technologies 6530 replacement boards).
User wikokim on the forum.classic-computing.de bought this system in 1978/79. And published the following documents and ROM dumps.
The ESCO 1 was DM 520, the ESCO Monitor DM 460 (German Marks). The backplane was DM 190. He added a 16KB Static Memory Card from KF (?) and modified the Card to work with the ESCO Bus. He also made a LED based Bus Monitor including the KIM-1 based Single Cycle /Single Step Logic.
ESCO stands for Europa Single Board Computer.
The ESCO system was desigend and sold by the firm Neumüller. The firm still exist, though they remember nothing about the ESCO.
The ESCO SBC has:
- 4 SRAMS TMS4045 makes 2K RAM
- several address decoders, including 145 like the KIM-1
- A 4MHz crystal, divided to 2 MHz or less MHz.Since the 6502 is the 1 MHz NMOS part, likely 1 MHz
- the 6820 is a PIA, the empty slot is for a second PIA
- 4 IC sockets for2516 EPROMS, here with monitor and an Editor/Assembler
The optional ESCO monitor, consisting of a EuroCard and a separate keyboard PCB, with the usual hex keybaord, 6 seven segment LED displays, audio cassette interface, and a serial 20 mA TTY interface.
Texteditor and Assembler in action. Started Texteditor with “Q” (home made ESCO Monitor extension q $8000). Then “T” to start Texteditor. “TEXT:” entered 2000 (start of texteditor Storage Area). “N Or O” for new or old Text. Entered “O” , “2000 2038 0005” Text Start @2000 to 2038 5 Lines entered . “A T” Starts Assembler 1 Pass to Terminal (SYMS, SYME, Code left default) . “D” Starts pass 2 to terminal.
Available documents and ROM dumps:
This page is about the operation and use of the Rockwell Single-Chip RSC-FORTH system as implemented in the Rockwell R65F11 (40-pin) and R65F12 (64-pin) FORTH-based one-chip Microcomputers and in the Rockwell R65FR1 FORTH Development ROM. Also about the the RSC Forth ROMS as available for the R6501Q IC.
R65FR1.bin — Forth kernel V1.7 for 65RF11
R65FK2P.BIN — Small FORTH kernel for R6501Q
R65FR2P.BIN — FORTH development ROM, pairs with R65FK2P
R65FK3P.BIN– Large FORTH kernel for R6501Q
R65FR3P.BIN– FORTH development ROM, pairs with R65FK3P
R32TH-12 R65FK3P1.7 RSC-Forth Kernel
R65FK3 im 2764
Rockwell made many 6502 variants. Some were ‘SOCs’, complete computers in an IC.
and Rockwell was strong in Forth, e.g. RSC-Forth products
The Databooks (e.g. 1984 and 1987 Data products) contain many examples of these lines.
In my collection I have two:
- R6501Q one IC R6501AQ and one R6501Q in the Glitchworks R6501Q kit
- R65F11 one IC, a ‘Forth’ computer
