Hi Jeff,
If you worked on the B7700 then you definitely had a lot of panel switches and displays to play with. I started with the Great Valley Labs (1968) and have been involved with every Burroughs Mainframe (B and A Series) and the ES7000 and even some West Coast Stuff (UNIX and Memory sub-systems), retired in 2001. I have spent many days/months toggling switches and interpreting status on the panels and loading the card readers. I was very happy to see the switches go-away and the bootable machines come about when the IDA was fully implemented. IDA was not the easiest debug/test tool to work with either but it was a lot faster than doing the panel and single step thing. The INTEL/MS platform and later designs used a lot of JTAG interface and the ES7000 was a combination of things using the TCL, JTAG, imbedded diagnostics and programmatic functional tools. As you know to work on these machines was not a job but a life-style you either loved it or hated it. I stayed with the company for 33 years so I guess you could say I enjoyed it. 73, Ray, N0FY SKCC 3704 FH 997 _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Kashinsky Sent: Friday, May 09, 2008 10:25 AM To: [email protected] Subject: [softrock40] Re: softrock for 2m? Nostalga mode off: Assuming I want to use my RXTX6.2 as a 10 meter if for a 2 m xverter for FM repeater use (which I don't want to do), how would one handle the 600 kHz offset between rx and tx? I would guess that you would need to switch the osc between two frequencies that would give the proper offset when switching between xmit and recv. Would that be the same technique if you wanted to operate split in hf? Or can the PC software handle that (assuming that both xmit and recv are in the passband)? Nostalga mode on: 1st xmiter was 6J5 osc/807 final. 1st computer of my own was an 8080 built from boards I designed for a project at work. 1st computer was a Burroughs B7700 mainframe that I helped design in late 1960's. 1st SDR is a RXTX6.2 that is almost built.
