The recorder I have seems to have a full roll and I found a UK company that claims to sell it but at a stupid 'go-away' price (~30 bucks a roll!!) with an MOQ of ten rolls, so I'm not really tempted! If it wasn't for the sprocket holes, which aren't driven but have a LED/Photodiode looking through them (for timing?) a roll of thermal 2" till-roll would work I suspect.
You make a good point, I will look out for an X-Y module - I still have a working HP7035B Chart Recorder somewhere too!

Do you have a source of the paper?
If not then I prefer the XY chart recorder outputs, since they can drive a digitising scope and (theoretically!) allow it to be stored underwater :)

Hi Tom,
Had a look at the stripline and yes, I have a short bit of braid hanging out the end too, Fig 4-26 on Page 4-27 of the manual seems to show it just hanging loose (didn't know they were that laid back in Oregon?) so I guess that's how it's meant to be.
Just waiting for the last of the correct replacement parts to arrive from Digikey (takes a day or two longer to get to the UK) and I'll replace the tacked-in temporary bits and then see if I can run through the test/calibration procedures, but it's looking good so far! Just the chart recorder to look at now.

I have one other 'loose end' wire on the 1502 which also puzzled me, what looks like it could have been an earth connection at the rear (TD end) of the strip line, but nowhere obvious that it might have linked to.? My 1502 has a somewhat below spec rise time and I wondered if this could be linked to the missing earth connection.
