I have some of the paper tapes too with Digital Equipment Corp on them.
Mine also have various tests on them and some say Basic. However mine are
not in spools--mine are folded over on top of each other like 8 inches long
before being folded back on itself and then they are stored in a fancy blue
case where you slide each folded stack into. I am trying to figure out if
these are any good to anybody or whether they are only good on one specific
system. Can someone help me out here. I am pretty sure they are from a
large DEC computer used in a university in the 1960s and 1970s becuase the
dates on them are from 1965 to 1978.

Subject: DEC PDP-8 Paper Tapes?
I picked up a bunch of unknown paper tapes last week. I was
sorting through them today and found several tapes that have
"Digital Equipment Corporation Programmed Data Processor"
printer along the length of them. The label on one of them also
says "Memory CKR BRD (LOW)", "Memory CKR BRD (HIGH)", "Memory
ADDR BRD (LOW)", "Memory ADDR BRD (HIGH)". That one also has
"PDP-8" written on it in pencil. So I'm guessing that these are
all for the PDP-8. The tapes are marked variously "DB3", "DB4
SIMAT #1 3 SW TEST", "PAL III", "Combined BB#51, INT #15, CORR
#21 and Patches 1-11". Does anyone know what these titles mean?
All of the tapes are on blue plastic spools that are 4 inches
in diameter and 1 1/4 inch thick. Each spool has a removable blue
plastic cylinder (with one end closed) that slips over it. In the
center of the spools are white plastic inserts with a hole and
three radial drive slots. The covers are marked "Reel-Dex Part
No. 30" and "Numeridex Incorporated Wheeling, Illinois 60090".
It's pretty obvious that the spools are made to be used directly
in a PT reader. But does anyone know what kind?
