Other than the front large brass face plate, all other parts where custom made, fit, and function . Below is a short 2 minute video of the Main cabinet build process. end of part 2
My Cosmac 1802 build
Back in 1976 Popular Electronics published an article about an RCA CPU called CDP1802, COSMAC ELF. This was to be the entry point to computers for me. Had fun building it on a perf board and point to point wire soldering. Below my collection of "1802 bibles". Each one of these magazines had 1802 projects/ programs/ or schematics. Fast forward some 4 decades and now I'm re-visiting that humble little computer and super sizing it a bit. Here is my latest incarnation the Steam Punked COSMAC VIP - ELF project. What is it? Its made up of 5 parts, The MAIN cabinet, The Glass TUBE Display, The BCD-HEX keyboard, The ROTARY HEX keyboard and Audio Speaker (horn), and finally the VIDEO CRT display unit. The main electronics are made up of custom made PCB 4" x 4" stacked on a 5" x 10" motherboard. They are located in the MAIN cabinet, ( the unit with the 8 blue 7 segment VFD displays). Above are the main ELECTRONICS located in the cabinet shown below.
