Hewlett Packard (HP) Pen Plotter Service Information required

Can anyone help with Service Manual / Hardware Support Manuals for the HP Pen Plotters?

I've gone through the hpmuseum.net, hparchive.net sites but have a few requirements that these did not fill. Of course, I've checked all auction sites too.

In particular, detailed schematics and test information for the 7550B and the Draftmaster RX Plus series. These units were some of the last HP pen plotters produced and detailed service information is difficult to find.

Thank you in advance for your help, TomC ps: I've already posted this to comp.periphs.printers with little/no results so thought I would ask here.

Thanks, TomC

I checked my files and don't have it. What I do have (if you're interested) is an HP DraftPro Plus, in good condition, one-owner, etc..

36", 8-pen carosel, lots of new pens, etc...

That's for sale cheap. (Florida) I never use it anymore, and it has low hours overall. Have WinLine driver, etc...

If what you need can be found in the User Manual (HPGL commands, etc..) or how to wire the serial port, etc..., I'm happy to provide. But no schematic is in the file. :( I suspect the above won't suit your needs, but just thought I'd mention it in the spirit of early spring cleaning.

Thanks for the offer; if I happen to have a trip to Florida, I will let you know! (or if you can deliver it to Michigan, that could work!)

I do have most all of the usual documentation, but would like to obtain the 'Service Manual' or 'Hardware manual'.

What's the difference between the 7550A and B? IIRC, I had an A (since discarded) so that means I'll have the SM for the A here (somewhere).
