I came across this interesting device:

http://prologix.biz/gpib-usb-controller.html

At $149, at least it is an available device e supported by the company that sells it. However, it seems to be designed to plug onto a piece of test equipment and then a modern computer will control the instrument from its USB port. I'm not so sure if it works the other way around, with the HP-86B being the controller.

Does anyone here have any experience with something like this? What are your thoughts or suggestions?

2225A's can be found on eBay for less than $100. I recall seeing a 2225 recently for $25 plus shipping. The primary concern with ThinkJet's is that the ink is (was?) corrosive and if it leaked out of the printhead it was usually all over the flex connector and carriage assembly.

<...snip...>

This usually destroys the flex cable. Best to shop around and find a printer with a good flex. Also, Martin has a procedure for modifying QuietJet flex cables to work with the 2225.

The USB-GPIB controller will be of no use connecting a printer. What you could do is connect a PIL-Box to an 82938A HP-IL adapter and then print to the virtual printer in ILPer.

My setup for printing from 86B is I have a National Instruments GPIB-> Serial adapter, they work very well as they support Xon-Xoff protocol which makes it easy to drive serial printers. I also picked up a Quadram MicrofazerII which supports serial or parallel input and out, switch selectable from the front panel I use it to drive one of my 2671G thermal printers. I have a 2671G with HPIB interface, if you are interested send me an email.

(07-07-2017 08:49 PM)smp Wrote:  The manual for the 82938A says that it requires either the IO ROM (00085-15003) or the Plotter/Printer ROM (00085-15002). As luck has it, I have the Plotter/Printer ROM. Oh, lucky day! But wait! I have also read that the ROMs that start with 00085 are for the HP-85, and I might actually need the equivalent Plotter/Printer ROM for the HP86/87 (00087-15002). Is that right?

(07-07-2017 10:37 PM)rprosperi Wrote:  HP-83/85 machines use ROMs with p/n starting with 00085-xxxx, while HP-86/87 machines use ROMs with p/n starting with 00087-xxxx. There is a pretty complete list here:

https://en.wikipedia.org/wiki/HP_series_80#ROM_extensions

You cannot use 85 ROMs in an 87 and vice-versa.

Many of the early interface module manuals were written before 86/87 models were released and therefor only list the 83/85 ROM model numbers. So, this translates to you will need either ROM 00087-15002 or 00087-15003.

However, and this may be a big however, on the HP-85, that ROM contains both PRINTER and PLOTTER support. On the HP-86/87, PRINTER support is built-in, so advice to add the PRINTER/PLOTTER ROM may not apply.

I would guess, from the wording in the IL Interface manual, that the needed support for this interface is built-in to your 86/87 and additional ROMs are not needed for printing. Likewise, you probably would need to add to add the PLOTTER ROM for HP-IL plotting.

Maybe I'm too thick to do the search properly, but I keep coming up with Serial-to-GPIB interfaces. The exception being that National Instruments may actually make what I'm looking for - they have some $500 and some $600 devices. Sigh!




Wow. This is starting to get complicated... I love my HP stuff, I love my HP stuff, I love my HP stuff...

What I have is a NI GPIB-232CV-A I had to be pretty patient to find one at a price I liked.. less than $100.

(07-08-2017 12:38 AM)Dave Frederickson Wrote:  It looks like the least expensive solution would be the 82938A and ILPer, unless you can find a decent HP-IB printer for less. Be aware that ILPer doesn't emulate the graphics capabilities of the 2225, but it does allow you to make soft copies the can be printed out later and the 82938A doesn't support mass storage devices. Also, pyILPER has a plotter emulator, but you will probably need the 86/87 Plotter ROM for that.

And before you go shopping for ROM's, consider a PRM-85.

I have one of these, and yes, it can run in either controller mode or device mode. However, it is essentially just an HPIB to USB serial converter, handling the details of the HPIB bus transactions. The device attached to the USB side has to provide the smarts to either act as the controller or as a device from the HPIB data payload point of view. I believe the manual should be readily available on the Prologix web site if you are interested in the details on how it works. I've used mine to transfer data to/from my 71b using the HP IB-IL converter.
