Others on this list probably remember better, but when I arrived at BBN in
1983, most of the company's local area network was a standalone IMP network
(net 8, as I recall) that had about as many IMPs as ARPANET and, beyond
keeping the company connected, was used to test major releases of IMP code.

I was lucky enough to be given an office on the 4th floor of 10 Moulton St,
which had one of BBN's few Ethernets (net 128.89), I believe to support
Rick Schantz's projects on distributed object oriented systems and Bob
Thomas's project on multimedia mail.

Soon BBN moved to put Ethernet everywhere (I gather this led to lots of
cables tucked above ceiling tiles -- which caused issues when the fire
codes were updated and we wanted to upgrade the wiring, I think in the
1990s).
