*****Tektronix Graphics Terminal Stuff***** I have acquired in my shop, a couple boxes of Tektronix "stuff". I really didn't know what it was until I was working on cleaning up the shop and bothered to look at it. Here is what the manuals are called: 1) 4100F3A DMA for PDP-11/VAX installation 2) MDB Systems INC. long line RS422 extension board for MDB DR11B DMA modules for PDP11 and VAX computers 3) MDB-DR11B Direct Memory Access Module for use with PDP11 and VAX computers 4) TEK 4115/4120 series option 3a/3c interface Everything that WAS sealed is STILL sealed, including books, cables, and boards. The main cable is 30 feet, which appears to be a limiting length for this item. Since none of our 4125/4128 stuff is within 30 feet (or even 300 feet) of the VAXen, we seem to have no use for this little set of goodies. I asked by Supervisor and determined that some form of sale or trade might be negotiable if anyone is interested. I'd really rather not have to screw around with doing this one piece at a time, and I have the feeling that you need ALL the parts to make ANY of it work. Unless of course you already HAVE one and just need spares/replacements. For the record, this probably decreases the screen refresh time on one of these units *considerably* as opposed to a serial interface. If interested, please email me and we can work out some arrangement. I will handle this on a first-come, first-served basis.
