Thanks Bill. The closed-loop nature makes me think of a NC tape that intentionally repeats a series of steps, perhaps as a station in a line operation. Don't believe that this particular seller has a particularly good reputation, either. Perhaps there was some late model UNIVAC system that might have been used to produce these tapes to then drive a sequencer-controller (assuming that there's anything UNIVAC'y at all about them)? -----Original Message----- From: vcf-midatlantic [mailto:vcf-midatlantic-bounces@lists.vcfed.org] On Behalf Of Bill Dromgoole via vcf-midatlantic Sent: Sunday, December 02, 2018 11:44 PM To: vcf-midatlantic Cc: Bill Dromgoole Subject: Re: [vcf-midatlantic] UNIVAC Black Paper Tape Good question Paul. To me its just ordinary black paper tape . Could come from anywhere and be from any computer. Would need to see any hand written pencil notes at beginning of tape to have a clue . It is the same format, that is eight level that we use on the 1219B but I doubt it is anything interesting especially at those prices.

I see no evidence of provenance. However what I do see appear to be cut from unusually heavy stock and in the form of closed loops. They appear to be 8-level (3-sprocket-5). Do these make sense for use on a Univac system? How so, and which system(s)? Happy Post-Festivus, paul
