What did the Shuttle GLS user interface look like?
I'm building a simulator for the CCMS. I have a lot very detailed info on the OS and base applications (including the GOAL executor and FEPs) and even a pretty good idea how the GLS works (based on S0007 and the various GLSDD's that are floating around). Surprisingly, there's virtually no information out there about what the actual screens the console operators interacted with look like. I've found a single youtube video that briefly shows half of a barely visible screen here:
(skip to 12 minutes in)
From this video and a bit of guesswork I've reconstructed the display in the attached image. Does anyone know how accurate this is, and what should be on the right side of the screen?
A couple more specific questions:
- It looks to me like the top section with the timers is constant across all GLS displays, and the lower section is replaced depending on the particular GOAL program you're interacting with (SLP07 in this case). Is this right?
- what do the marks under the VFY/MIP/LIP columns signify? I'm assuming the columns correspond to the state of mainline verifies, the mainline interrupt processor and LCC interrupt processors? Does it signify if there's a violation for that milestone?
- what does 'ML REVERIFICATION' do? Is it a user invokable action?
- I'm guessing the 'BFS' and the top center is indicating the current ops? Should there be a matching 'PASS' mode next to it?
- Although it's hard to see in the source image, above 'LAST HOLD' it looks like 'CPERS', which would be 'contingent performs'? Is that indicating whether any CPERS are currently running?
- similar to CPERS, I *think* that's 'TB0' in the lower right box, which would be 'Timebase zero'? is that just a display, or is it indicating something else?
These are pretty obscure details to be worrying about, but I'm basically looking for any info to make this as accurate as possible. Any insight on what this or other GLS screens should look like or how they behave is greatly appreciated.
Thanks!
