Hi Bill, thanks again for your considerations! --- Bill Degnan <billdegnan at gmail.com> wrote: No, there is no evidence. But they founded ROLM in 1969 and they had no experience on designing a MIL-SPEC computer (until than only highly specialized MIL-SPEC computers had been designed taking years each) and only limited experience on computers at all. So I can hardly imagine, that they founded ROLM, agreed with DG on the architecture, developed the design, implemented the shock and heat management, tested against the MIL-SPECs set up production within only 2 years. Here is a nice video of a discussion with the founders recorded by the CHM: https://www.youtube.com/watch?v=VyTuxVQgw6c Yes, maybe some where made for trade shows and to try out how to build a MIL-SPEC computer. But regarding commercial sales I am still sceptic (no proof as you say)... Thanks, Erik.
