Found their headquarter was at 1363 S State College, Anaheim, CA., so
may be why it turned up in scrap around here (Orange, Country, CA)
location if anyone is interested

Ooh. That might be one to bring my TVT and Mark-8 stuff to, provided we don't
have another winter like we did last year. I'm up in BC and we just got

to pass.. BC drivers are terrible on snow.

I just got another batch of tapes. While the customer specified 9
track, there are a bunch of 7 track/556 bpi tapes in the mix.
Anyone have a drive that they're willing to part with/loan for these things?
Thanks,
Chuck
