Rockwell AIM 65

The image is clickable


Rockwell AIM 65 is built around the MOS Technologies 6502 processor, just as MOS Technologies own computer KIM-1. The difference is that AIM 65 has better performance. If they had come from the same supplier, you might call the AIM 65 for the follow-up to KIM-1.

It was primarily designed for industrial and scientific use. The motherboard was equipped with five pc 4 KB-ROM sockets. Two of them were directly reserved for the operating system (monitor), two for BASIC and one could be used for diverse programming languages, such as Forth, Pascal, PL/65, assembler. Pascal, however, required an expansion modul.

Unlike the KIM-1, AIM 65 had an adequate keyboard with proper keys and nothing that resembled an overgrown calculators rubberkeys as many later computers had. There were also a 20-character LED display with 16 segments/character built-in. If you look at this with your modern eyes, these characteristics are not particulary much, but far more than what KIM-1 had.

Rockwell AIM 65 had something that not many later computers ever had, a built-in printer. It was placed directly on the motherboard, and even the holder of the calculator-similar paper rol was placed directly on the motherboard. It was only able to write with 20 characters wide. Everything that was written on the keyboard, could be printed.

It was produced a large number of expansion- or accessorie cards to connect to the AIM 65. Among all these modules some could be mentioned. Extra RAM; 8 KB static RAM and up to 32 KB dynamic RAM, disk drive control, IEEE 488 bus controler, single board computer (SBC), CRT controler.

Unlike the KIM-1, there were quite a number of different chassis for AIM 65. This copy has a plastic chassis that was fairly common. There were other plastic chassis and they had often no power supply built-in. That indicate that there were other models with a built-in power supply and they often had metal chassis.

There were also some AIM 65 computers which were hard to recognize as a AIM 65. That's when other companies who made them, gave them their own name such as "Siemens PC 100" or "Cybex Isokenetic System".
