I had worked on PC's and Computervision graphic machines prior to 1983,
and everything there was already OCO I think, so I didn't know any
better when IBM went OCO. I rarely looked at the fiche, but it was
really interesting to see PL/X (I think it was called) compiled into
assembler code. I do remember one time where (with someone else's help)
we found the cause of an error by looking at the fiche and reported it
to IBM - with our own fix of course :)

Hi Tom,
1983, eh?
The same year as the (expletive deleted) OCO policy.
I've seen IBM-lifers defend it on this forum, yet, it still did not/does
not make sense.
Regards,
David

I get it... I just heard from an old co-worker that sometime this
month they shut down the mainframe in Southern California that I
worked on from 1983 to 2013. That was my first exposure to an IBM
mainframe, and I think XA had just come out and people were busy
fixing programs to work in AMODE 31. There was a rack full of MVS
microfiche and a viewer at each desk. If we needed to send a dump to
IBM we had to create a tape and carry it across the street to the mail
room.

When I came to school in 1976, the computer was described as "loosely
coupled 370s". My exposure was via remote cardreader/printer.
When I started working here in 1981, there were still folks that had
rewired boards for what they had before that.
End of 2019, we moved from a 10 year old z9 to MFaaS with FNTS in Omaha.
