I have a box from Comstar that I was told was a "programmer" that allowed you to burn ROMs for a much larger computer. I did some research and found that COMSTAR made a Microcomputer based on the Intel 4004

Comstar Microcomputers, a part of the Warner & Swasey Company, also provides microcomputer development systems. As a part of these systems, Comstar developed a Process Control Language (PCL), which allows the engineer to create microcomputer programs using English language commands. This language allows the engineer to express on/off control functions in ladder-diagram terms and also provides a simple method for expressing most other control modes. " "Comstar offers a process control compiler that is used to compile the English language program into programmable read-only memory" (PROM) chips. This system can also erase chips, and edit and program chips in machine language. These chips are then plugged into a PROM memory module to provide program memory for a microcomputer. The Compiler is built around a Com-star-4 Microcomputer which uses the INTEL 4004 chip • LeRoy H. Anderson The Warner & Swasey Co. Solon, Ohio "
