That's one thing, and California's inventory tax, and the
fact that almost no manufacturing is done here, and eBay
killing off walk-in sales, and recyclers with required
destruct, and on and on.. The "Foothill" flea-market is
a shadow of what it was in the past.

It is a GE 400-series control console
you can see the maint panel on page 281 of
bitsavers.org/pdf/ge/GE-4xx/CPB-3
and Honeywell bought the GE computer operation in 1970.
I'd have to do more research to see if the 400-series was still
being produced after the purchase.

According to the Computers and Automation census, the first delivery of the
440 T/S was Jul, 69. After the sale, it shows up in the census under Honeywell
as the G440 T/S. It's a pretty rare machine. It dissappears in Mar '72 with no
known installations.
