My 1984 catalog indicates that it processes video signals, both analogue and digital. It appears, from the cables offered that the analog is a 75 ohm BNC and the digital is a 15 pin, prob. D sub Centronics type. Nothing indicates that it could be used with the 4051, also in this catalog. It's recording technique processes raster scan video with a fiber optic CRT. It does use both kinds of Tek dry silver paper, switch selectable. The High performance paper 7772 is capable of 125 lines per inch(LPI). The regular 7770 paper does 100 LPI. There is a RGB Mixer available for color to mono conversion. I may have a new one in a box if you get the 4634. The printer, new, comes with a roll of paper, 75 ohm terminator and manual. If it is new in the box I sure would recommend getting it. Few of these exist because they are valuable as scrap metal. In 1984 Tek wanted $7900 for this printer. A roll of paper cost $215, a case $750. If your Tek 4051 has a 15 pin video out in the back it might hook up to this printer. The connector on the printer is not a Tek GPIB port. Paxton
