Saturday October 25th, 2025: The power supply has been replaced with a modern unit. The chassis has an CPU board and a 4K static RAM board. Powering on produced some front panel lights, but no switches seemed to be functioning other then reset. Voltage checks revealed the front panel 5V regulator was putting out about…

Boeing News – November 14, 1968 In November 1968, Boeing engineers demonstrated to Brigadier General Mahlon E. Gates, Commanding General of the Army’s Sentinel Logistics Command, a hybrid computing system built around a DEC PDP-7A and a Type 340 graphics display. The PDP-7A functioned as an interactive front-end processor, handling light-pen input and real-time display…
KICKI is a dual PDP-10 model KI10 sn 522 and 606. While KICKI is current in preservation, we hope one day to have it running again. As of June 2025 former DEC LCG FE Gary Solomon has confirmed that both 522 and 606 CPUs have a complete module complement with the UML. To support the…

It is organized as top being the current exhibition organized in groups by area. All exhibits are considered permanent unless noted as a rotating exhibit. Remotely accessible machines are noted as OnLINE. August…
MIT-MC.ARPA was a DECSYSTEM-10 KL10 Model 1080 operated by the MIT MACSYMA Consortium, serving as one of the most significant systems in the development of AI and symbolic computation during the 1970s and early 1980s. Running the Incompatible Timesharing System (ITS), MC provided a uniquely open and collaborative computing environment where many pioneering software systems…
The Centurion Computer Corporation CPU-6 was a mid-1970s minicomputer designed primarily for industrial control, data acquisition, and real-time processing applications. Built using TTL logic and early LSI components, the CPU-6 featured a 16-bit architecture with a relatively fast instruction cycle for its time, often under 2 microseconds. It supported both fixed-point and limited floating-point arithmetic…

This system has 0 sponsors yielding $0.00/mo in support. Simulating a P7 point-drawing CRT is hard; the behavior of the phosphor is subtle and distinctive, and the optics of seeing the image painted on an actual period correct CRT are awesome. The ICM has the DEC 340 cabinetry and the CRT, but most of the…
Support for the project comes from your donations DECtape is a block-oriented magnetic media format more akin to the floppy disk than 9 track tape. There are four prevailing formats: LINC, 18, 16 and 12 bit. For years DEC distributed diagnostics, system distributions and sources on DECtape and our library consists of somewhere between 500…
