Silly BSD questions (Now Utek)

There are quite a number of versions of Utek (@&^!&^ Outlook won't let me capitalize the "t"). The first versions were for the National 320xx CPUs. This ran on the 6205's, 6130, and 4132. Later, a Motorola 68000-based verson was released. It ran on the 2nd-generation machines -- I can't remember the model numbers of off the top of my head. These machines came in between the earlier National-based machines, and the XD88 series machines, which were based on the Motorola 88000 CPU. The XD88 machines were quite powerful, and had really nice graphics processors that made things like 3D solids modeling run really nicely. Graphics performance was very high compared to many other vendors at the time. Unfortunately, Tek never really knew how to market computers. The Tek 4051/4052/4054, and to some degree, the Tek 4081, were the only real Tektronix computer products that were market makers. All of the rest realy never did generate a whole lot of interest except in specialized circles. The team that Tektronix had working on hardware and software called ECS (Engineering Computing Systems) at the Tektronix Wilsonville, OR. Campus, was world class. The talent pool they had was incredible. When ECS was disbanded and the development and products discontinued, it was a horrible scene. The folks in ECS had developed an incredible team atmosphere, and there was a lot of excitement. Many of the engineers had found their "dream jobs" in ECS, and those dream jobs vanished into thin air. I believe that there might be some issues trying to restore older 1st and 2nd generation Utek filesystem dumps onto an XD88 machine. Utek was very BSD 4.2-based. The XD88 version adopted some SVR4 stuff both at the utility level, and some system calls. Tek scrapped a lot of machines. Some ended up going up for sale at the Tektronix Country store for fractions of cents on the dollar. Some were sold at "fire sales". I have a working 6130, 4132, and one of the 68K-based machines. The biggest problem with the 4132 and 68K-based machine (I wish I could remember the model number) is that the 1/4" cartridge tape drive capstans turn to goo. The 6130 used floppies for loading up the OS. I still have all of the floppies (they've been imaged), and they still work. I have cartrdige tapes for the 6130 and 4132 Utek versions (not imaged), and did get one 1/4" tape drive working about a year ago, but ran out of time. Don't know if it'll still work. I really should try to image this stuff (at least dd images) sometime soon. Rick
