Here are the printers I fought at VCF: Anyone familiar with the Diablo? It powers up, is very clean but the print-head won't budge. I wonder if there is a lock-down for shipping or something I couldn't find... https://i.imgur.com/mZkjmcx.jpg <https://i.imgur.com/mZkjmcx.jpg> - Diablo https://i.imgur.com/CrcOmbA.jpg?1 <https://i.imgur.com/CrcOmbA.jpg?1> - okidata w error https://i.imgur.com/wdOMbpN.jpg <https://i.imgur.com/wdOMbpN.jpg> - okidata test print - it would print those few lines and then error.

We had one of those on our VAX in college. One year, I whipped up a little program that would use the Hershy fonts and the dot plotting mode on the printer to do banners in callegraphic Old English. I kind of treated it as a one-off, but a couple years later someone came up to me and asked how to use the program. That was the beginning of me learning that your throw-away one-offs are the ones that everyone will want and care about, and the ones you labor over focusing on the details of the craft are the ones no one will ever pay attention to.

If I understand your question correctly, no, I've never seen nor heard of a large printer with a DE9 connector. However, lots and lots of them have RS232 serial ports, but on standard DB25 connectors. That's how LSSM's big Genicom is interfaced; it's connected to a DECserver terminal server so that multiple systems can access it. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Greenbar print
by Bill Degnan 28 Feb '21

28 Feb '21

Can you please send technical details of the printout? Ascii file? Characters per line? Is the printout file ready and all they need is a print or does thenoutput need to be formatted first? I recall you said it was roughly a hundred or so total pages? Maybe someone near the museum can look for the two DECwriter III's that might still be around the warehouse, or some other wide carriage printer there. If you put a new ribbon on one of those and attach to an old pc running word perfect paginated to 132 character lines you could at least try to print this at infoage. I bet there is some green bar in the warehouse When the file and details are available I would be happy to at least try to do of it too. Bill

I will try a clean & lube on mine first - the internal assembly looks highly optimized for initial assembly, not so much the reverse, and I take back the comment on cap quality.

Alas I'm in the opposite situation. I'm in driving distance (1.5 hrs) from the museum, but the only dot matrix printers I have are 80 col, with ribbons of doubtful value. So I don't think I have the right stuff. However, if there's narrow paper available and it will serve the need, I'll be happy to pull them out and test them.
