I lost my last 5081 years ago, at the same time my -0 of the 360 reference
card, yellow instead if green, disappeared from my desk drawer. We weren't
issued desk keys because "everyone is a professional and can be trusted." That
-0 was considered a relic as we were on VM R3, going to R4, at the time. It was
just before SP, and Jim Brergsten's famous vulture T-shirt ("VM SP is waiting
for you")

Wow! 5,081 cards in your pocket!?
Must be really small cards or really big pockets!
Talk about playing with a full deck! :-)
Ah, it's Friday, isn't it?

Re: DDR to standard labeled tapes
Watch that dark ages stuff, Chuckie. By the time I saw that problem, I
was
no longer keying on an 029 or maybe 026. I had graduated to a 3278 or
3279, altho I did then and still do carry 5081 cards in my pocket.
