They consist of: System 1 System 2 MDB Qbus box MDB Qbus box 12 Mhz 68010 10 Mhz 68010 1 1/4 Meg Ram 1 1/4 Meg Ram a DEC Synchronus board DHV11 2 DHV11's Emulex Sc03/Bx disk controller Emulex Sc03/Bx disk controller CDC 9715 (160Meg) disk Qic II 1/4" streamming tape drive Excelan Ethernet board Excelan Ethernet board Fujitsu Eagle (474 Meg) disk Also, the EE/CS department here owns 7 or 8 of them. So far neither of the systems has ever crashed (execpt for power failure). The first system we has been up and running since January; the second one since June. The EE/CS department had problems with one of them. After about a year of running the power supply in the Qbus box died. The rest of them have been running continuously for about a year and a half. In fact, over labor day weekend the air conditioning in the machine room went out. The temp rose to about 95 degrees. The ISI's were the only thing still running! The 4.2bsd port that ISI did makes them look just like a Vax. The speed of the 12 Mhz 68010 is about the same as our Vax 750. I/O is a bit slower (because of the Q-bus speed limitiation). The real difference is the price! I had a chance to try one of their VME based systems. I was very pleased with it. It connected right up to our ethernet with no problem. The system looked very much like a Sun (Bitmap graphics, etc...). It has an editor that is like MacPaint, an Icon editor, and other misc utilites. I found it very easy to use. -- - Jim ihnp4!uwmcsd1!james or uwmcsd1!james@wisc-rsch.arpa Brought to you by Super Global Mega Corp .com
