What is the Q/UniBus board set?

Hi. I got this Q/UniBus board set: http://www.unixag-kl.fh-kl.de/~jkunz/qbus_1.jpg (105 kB) http://www.unixag-kl.fh-kl.de/~jkunz/qbus_2.jpg (128 kB) The first is the top card (towards CPU). I think it is QBus, as I got it together with some other QBus / MicroVAX stuff. On these cards are: lots of TTL ICs and PALs 4 x TS2901 (=AMD 2901 bit slice?) 1 x 2910 1 x DEC 010B 19-14038 I 8415 (The DIP 20 with golden heat spreader) 10 x AM27S35 (Microcode PROM?) 2 x Harris D1-15530-9 2 x "Transceiver" 1 x DC/DC converter. 2 x 82S09N 8039 2 x V61C16P16 1 x 10 pin IDC connector (upper left on bottom card) There is a cabinet kit with two BNC connectos and two blue koax cables, labled A and B that connects to the 10 pin IDC connector. The two cards are interconnected with two 40 pin ribbon cables. This numbers are on the PCB: 5079322-001E 5079312-001F 5079310-001 5079320-001 What is this? -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
