Vt180, whats the story here?

<A VT125 is a STP board that is also called a Graphics processor board. It's not a STP board. the stp board is a little bord used to interconnet the two or (technically) a printer buffer board. The VT125 option ( have two) is a double board set that adds in like the VT180 card and is the same size overall as a VT100 card (that also has to be present). I know, the engineering group I was with was formerly the TERMINALS and PRINTERS people at DEC. Later it became two distinct groups. I still keep a hybrid VT100 that has VT125, VT180 and PDT11/130(the VT180 card and the PDT can be swapped in a moment as both would cook the PS nor woth the fit!) in the same case. Definately not factory but it allows me to have something that is a genuine VT100 for those times when nothing else will do. I think Bernie, me and a few odd people had real VT185s. They were scarce. The reason was the interconnect card (different STP card than plain VT100/VT180) was needed and I don't think it ever got to production. Allison
