I was right? Yay - it's been a long time since I dismantled an MV2000 :) One of these days I'll get round to making one good one out of the 3 bad ones I've got downstairs. No need to apologise either - the more answers we get to questions the better I think! Cheers w

AFAIK, yes, you have to remove the extender before you can get to the screws to slide the main cover off. Do you have the ethernet board installed internally? Every uVAX2000 has the 10Base2 BNC installed, but not every machine has the internal board with the LANCE chip (7990) plugged onto its daughter card pins. My first uVAX2000 did not have ethernet installed. It was cheaper to buy a VS2000 and mix the parts (disk, memory, Ethernet) than it was to try to _buy_ the Ethernet board as a spare. The VS2000 case I got had an AUI connector on the back that the uVAX2000 did not. For the unaware, the difference between a VAXstation 2000 and a MicroVAX 2000 is the plastic badge on the front, sometimes an add-on framebuffer in the VS2000, and the position of a jumper that identifies the CPU type as one vs the other (KA610 vs KA620?) to the ROMs. The firmware is the same, as is the default behavior when loading VMS (the VS2000 was envisioned as a personal workstation, the uVAX2000 more of a MicroVAX-II with limited peripherals). Fun machines... not quite as much fun as a Qbus box, but if what you want to do fits within the limitations of the few peripherals available, it's just as good as a BA23 MicroVAX setup. They do have an NCR 5380 chip that supposedly can be used for SCSI disk rather than just the TK50Z, but the patches to the firmware that are floating around don't match the revision in any of my boxes, and I've never spent enough time to sort things out. It's not fast, but a 1GB 3.5" disk is going to be a lot more reliable than an RD54 (and a lot easier to find). -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 19-Mar-2004 13:48 Z South Pole Station PSC 468 Box 400 Temp -64.7 F (-53.8 C) Windchill -87.5 F (-66.40 C) APO AP 96598 Wind 6.2 kts Grid 187 Barometer 680.2 mb (10619. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
