[cctalk] Looking for info on BAI Data Products model 1230 paper tape punch/reader

Hello All, I have a PDP 11/05 that I’ve been restoring slowly over the last few years. I’m to the point now where I’d like to get a paper tape reader attached to it. The only reader I can find in my junk is a Bower Associates BAI Data Products model 1230 punch. I’ve put a picture of it here

[cctalk] LCM news?

Did anyone else just get the semi-automated-looking email from the Living Computer Museum reminding that the online collection is still online and how to access it? It was a bit of a shock to me - I was aware that the online collection was still accessible, but it just seems ‘strange’ to get an

Toby, I was unable to find them on Bitsavers or Vaxhaven so I would suspect they have yet to be captured. What would it take to get them scanned? That type of binding makes for quick work in a sheet-feed scanner. Ian > On Aug 15, 2019, at 3:28 PM, Toby Thain via cctalk > wrote: > > Hi, >

There may be no duties or tariffs, however you may have to pay sales taxes on the value of the machine, so make sure you have paperwork showing how much you paid for the machine, or paperwork showing it is a gift. (This is the case for me bringing in hardware from the USA into Canada) Ian >

Jim, These are non-polarized (or bi-polar) electrolytics. An example is the following digikey part number: 493-12697-3-ND You can always whip one up out of your junk box - just put 2 normal (polarized) electrolytic in series with the polarities alternating (for example, connect the two

Nice find! I have a vague recollection of doing repairs on something similar that was used as a Unix machine to run cash registers at a pharmacy during the late 80s. Sure looks familiar. Any idea what it runs? Ian Sent from my iPhone On Jun 14, 2015, at 12:47 PM, Chris Osborn
