POK had something like that called "redcap". it was not only useable

the cambridge science center

adapted it for tracing instructions and storage references for
application that did semi-automated program reorganization
... optimizing operation for virtual memory operation.

i had gotten involved in rewritting some of the redcap interfaces to
improve the operation/performance for use in the science center
application.

the science center application was used quite a bit internally by a
number of product developers .... for instance the IMS group in STL
made extensive use of it for analysing IMS execution.

"San Jacinto" morphed into RIOS and RS/6000, old news item

From this week's Management Information Systems Week...

IBM's Austin, Texas, manufacturing facility - where the RT was born -
is currently putting the final touches on a 10-mips Unix-based
workstation, code-named "San Jacinto," according to an industry source.

"It's a follow-on to the RT, due in the first or second quarter" said the
source. The San Jacinto will be Posix-compatible, as well.

... snip ...

as i've mentioned before RT originally started out with ROMP (chip)
and cp.r (written in pl.8) as followon to the office product division
displaywriter. when that project was killed, they decided to retarget
it to the unix workstation market ... subcontracting for a at&t unix
port with the same company that had done the pc/ix port.

note, something of an aside ... in hsdt
http://www.garlic.com/~lynn/subnetwork.html#hsdt

we had a number of communication things going on simultaneously
.... there was the internal network
http://www.garlic.com/~lynn/subnetwork.html#internalnet

similar technology was being used in bitnet & earn
http://www.garlic.com/~lynn/subnetwork.html#bitnet

we were also in networking technology involving tcp/ip, the internet
and the nsfnet backbone; some of this had nothing to do with
mainframes and some of it overlapped with mainframes and/or
bitnet/earn activities.

tcp/ip overlapping with mainframes ... i had done the rfc 1044
implementation for the mainframe tcp/ip support
http://www.garlic.com/~lynn/subnetwork.html#1044

the base support got around 44kbytes/sec using a 3090 processor ...
the 1044 support in some tuning tests at cray research was getting
1mbyte/sec thruput between a cray machine and a 4341-clone ... using
only a modest amount of the 4341-clone.

That's nothing compared to the dozens killed by the recent bird flu
"pandemic".

Richard, is this the service manual for the terminal that you bought?
