Hello. I just begin the development of the Univac I simulator. By the moment I am doing one simple prototype of the CPU with all the Instruction Set and the Registers, plus ten simulated Uniservos in form of ten plain ascii files. I don't try to reproduce by the moment the timings or the exact cycle of the data and/or instructions along the system. In a later issue I have the intention to convert the simulator in one Bob Supnik's Simh compatible. And, finally, I shall try to develop one GUI for the Sim, and here is where I need some kind of help. All the photographs I have are in black and white, and I need some help about the real color of the Univac I components. I am working actually with the Supervisory Control (the Huge Console of the Univac I) and I need to know if somebody knows its exact colors: that is, of the Metallic components, and the light and blinking colors too. All help should be agreed. Thanks and Best Regards Sergio Pedraja
