Looked at microprocessor code development on TymShare for my postgrad days
in Bangor University, in sunny North Wales, 1974-1977.
Realised early on that 'on the meter' coding was not a good economic model,
which rationalised the purchase of an intellec MCD 4/40 and a TTY instead.
Coding then was down to how much midnight oil you were willing to burn,
rather than how much it cost the research grant budget.
And I've still got the original intellec running on my adjacent home office
desk!

I think this is the company which was the carrier
involved in Clifford
Stoll's "Cuckoo's Egg" story. Nit picking time billing lead to finding
a hacker guy.
My friend Ron Vivier who was a co-worker before the issue moved to the
Bay area and is mentioned in Cliff's book. He worked at Microdata in
Irvine when I worked with him and moved north and went to work for tymshare.
BTW, the timesharing model sucks if you're forced into it. Never ending
charges for service vs. having a system. In the early 80s i went to
work with a company which had a timesharing business they'd inherited.
We had minicomputer which at the time for cost considerations and needs
allowed for sharing the resources. But some companies were predatory
and not nice with rates or services.
Our business went away when the PC version of the Pick Operating system
came out and the customers drifted away onto their own owned machines.
FWIW one customer which had been on our system for years was Western
Digital
