This strange computer was designed to be a development system for 6502 based computers. It has no display except for a small 20 character LED screen and a very small thermal printer located directly on the motherboard which can print everything that is typed on the keyboard.

The board features five 4 KB-ROM sockets. Two of them are dedicated to the AIM monitor program, including an instant input assembler (no labels) and a disassembler. Various programming languages (BASIC, FORTH...) or custom applications could be added in the three remaining sockets.

Several cards were developed for this machine, especially language cards and ROMs: BASIC card (BASIC language with floating point mathematic capabilities), PL/65 (a mixture of the PL/1 and Algol languages), Instant Pascal (an interpreted version of Pascal), Assembler and the FORTH programming language.
