PROMAX MI-650 trainer

1979 – PROMAX MI-650 trainer Educational trainersEducational instruments division was the result of our close commercial relationships with universities and technical schools. Work here was closely tied to the study plans of universities and technical schools in order to provide the educational material required by a variety of disciplines. Design work was begun on the MI-650B Microprocessor Trainer, based on the 6502 which appeared in 1975.

Updates to KIM-1, AIM 65 and SYM-1 pages

With the help of users on the German Classic Computing forum I ahve added many manuals and magazines in german about those systems:

AIM 65 PC100 manuals
MICROMAG magazines
KIM-1 manuals in German

I also added books on the 6502 in general and on the KIM-1, SYM-1 and AIM 65 to the Books section.

Reading old magazines is always fun, from the period 1976 to 198x magazines were filled with articles on the 6502, the KIM-1 and other SBC’s.

German, Dutch and English magazine articles extracted here.
Kilobaud, Byte, Dr Dobbs and of course the dedicated 6502 User Notes, MICRO Journal and Compute are valuable sources, but look at the many magazines on this page!

Superjolt manuals and schematics

I have added Superjolt manuals and schematics to the Jolt pages

Datac 1000 more information

Added some photo’s, a good schematic and user group newsletters to page devoted to the DATAC 1000, a small TIM-1 (6530-004) system, a very early 6502 SBC, as used by the Philadelphia based PACS users, manufactured by Datac engineering.

Data Handler, an early 6502 SBC

The Data Handler is a SBC (actually two boards!) built in 1975 by Western Data Systems Corporation.
One of the first computers based upon the then new 6502, as the KIM-1. Jolt, OSI 300.

Photos and blog about this SBC by Armin Zink, who owns a Data handler.

The following text and scans of the manual are by Armin Zink on his blog.

Datac 1000, a TIM 6502 SBC from 1976

This single board computer was premiered at the club’s August 1976 meeting in Atlantic City, NJ. Once “perfected,” the computer helped introduce many PACS members, and others,to the field of microcomputers. The official manufacturer of this computer was Datac Engineering of Southampton, PA.The computer was available in two models: the $185 “tutorial” version and the fully populated and tested version for $345.In either case the 6502 CPU was included. Computer was instantly usable and featured expansion capabilities, touch sensitive input keypads and a documentation package.The computer was so revolutionary that it was featured in Byte Magazine’s July 1977 edition.

KIM-1 Simulator at version 1.1.4

The KIM-1 Simulator is now at version 1.1.4. Not much news, just some small steps. Windows executable is updated, Linux versions require compiling sources.

– SST switch now tells it is not to be used for debugging.- Use of Lazarus Icons to improve design, Main menu now shows icons:
