Re: TMB11 drawings?
> From: Al Kossow > done. Thanks! I've spent a while poring over them, and I can report that the tape interface on the TMA11 and TMB11 is exactly identical. (Oddly enough, there are very minor differences between those of the TM11 and TMA11. Go figure.) So I expect that report of a TU10 plugged into a TMB11 is accurate. I've also compared the TM11 and TMA11, and they have the ssme complement of Flip Chips, with one exception: the TMA11 adds an M7854 "OPI/BTE Detector" - not sure what that might be. It does not seem to be, as I had guessed, for support of 1600 bpi, because the TMA11 only supports 800. I'll put together a brief page on the Computer History wiki containing all i've gleaned covering the TM11/TMA11/TMB11 (pinouts of the drive cable, Flip Chip backplane chart, etc). Noel

Anyway, there are indications (above) that it will also work with a TU10. If the TMB11 prints get scanned in, I can take a look them, and see what gives. Further (third) clue: the TMB11 Ops manual says "The TS03 tape transport operates at only one density (800 bpi) and iin only one mode of operation (9 track). The TMB11 is capable of other densities and can operate in the 7-track .. modes." I expect this is to support these modes in the TU10... I originally thought the TB11 was TS03-specific, but after reviewing all the above, I have changed my mind. Having the drawings would be great; I could check them out to confirm that it really can drive a TU10. > we do have the TMA11 drwngs Also excellent! The TM11 ones are online, but not (AFAIK) the TMA11. So if that could get done at some point, too... :-) The two are very similar (a 19" rack backplane full of smaller FLIP CHIPs), so it's not like the RK11-C -> RK11-D, where they re-implemented it to make it cheaper. I'm _guessing_ the latter one can handle 1600 bpi, or some such, but with the prints, the difference could be confirmed. > From: Henk Gooijen > IIRC, I have the printset of the TMB11 and ISTR it is one inch thick! Hmm. No idea why - it's only a quad card and a hex card and 4 smaller standard UNIBUS FLIP CHIPs (M105, M7821, etc). Hard to see that generating 1" of paper (even with the wire list for the custom backplane - a hex-high system unit). Maybe that set includes the TS03 drawings too? Noel
RE: TMB11 drawings?
I have the TMB11 and the TS03. IIRC, I have the printset of the TMB11 and ISTR it is one inch thick!

TMB11 drawings?
Does anyone know of the whereabouts of a set of engineering drawings for the TMB11 (also a Technical Manual, although that's more of a luxury)? All I could find on it, online, was the Operator's Manual. Noel PS: In an older thread on TU10's/TM11's here: http://www.classiccmp.org/pipermail/cctalk/2015-September/011810.html I saw some queries about whether a TU10 could be connected to a TMB11. The answer is apparently 'yes', for two reasons: First, I found docs on a thing called a TMA11 (apparently intermediate between the TM11 and TMB11), and one version of the docmentation about it talks about the TMA11 and the TU10, but another version talks about the TMA11 and the TS03. So, by transitivity, if the TU10 works with a TMA11, and a TMA11 works with a TS03, and the TS03 works with a TMB11, the TMB11 must work with a TU10... Second, I have a report of a TU10 found plugged into a TMB11 in a retired computer.
