Rockwell AIM 65  
Written by Accutron on 2016-09-03  

The Rockwell R6500 Advanced Interactive Microcomputer, better known as the AIM 65, is a 6502-based single-board development computer introduced in 1978. The AIM 65 is based on the same architecture as the original MOS Technology KIM-1 6502 development system, introduced in 1976. The AIM 65 features an on-board 20-digit single line alphanumeric LED display and thermal printer, and a detachable QWERTY keyboard mounted on a separate PCB. The AIM 65 supports a number of different language ROMS, including assembler, BASIC, FORTH, Pascal and Rockwell's proprietary PL/65 language, derived from ALGOL and PL/I.

The unit pictured here is a Revision 4 AIM 65, manufactured by Dynatem in early 1986 after Rockwell had ceased production. Though the Revision 4 AIM 65 is quite similar to earlier iterations, the subsequent Revision 5 hardware features a redesigned clock generator and support for newer RAM and ROM IC types which became available over the production lifespan of the AIM 65. Relative to Rockwell-manufactured examples, the Dynatem AIM 65 is quite rare.

Dynatem AIM 65 Advanced Interactive Microcomputer.


The AIM 65 display module is constructed from a Rockwell R6520AP PIA and five Siemens DL1416B four-digit alphanumeric LED smart displays.


AIM 65, Rockwell R6502P microprocessor, R6522P Versatile Interface Adapter (VIA) and clock generator circuit. The Revision 4 clock circuit can be easily discerned from the Revision 3 circuit by checking the R3, R4 and R5 resistor values.
