The stuff used was real 3/4" finish grade with what appears to be oak veneer (mine is). The originals were fairly tough veneer and well fitted. Mitered corners and two cleats in the corner for a bit of stiffness. The front edge has a routed slot on the inside top and two sides to slide over the front pannel plate, The slot is 9/64 maybe 5/32" wide. Most of the early machines came with the dark stain wood but I'd like to find a metal one (less RFI). One of my NS* Horizon is wood cover and the other is missing the cover so I have a Lexan cover plate to allow airflow. Allison

Sabre IPI interface hard drives

by ian_primus＠yahoo.com

I've recently come into ownership of some Seagate 97229 1.2GB IPI interface hard drives. I just don't have any equipment that can talk to IPI drives. So, I was hoping to be able to convert these drives to work on SMD. Since these look and seem almost identical to the CDC/Seagate/Imprimis drives that I use already, I thought it would be a simple interface board swap. Granted, I don't have any 1.2gig drives, mine are 9720 8xx mb drives. So, here's what I tried. I tried swapping both boards (with believed good boards from a dead disk 8xx drive). The main logic board from the 8xxmb drive fits just fine - one of the connectors underneath has fewer pins, but it mates up. I was hoping that this would just mean the extra heads on the HDA would simply be unused. Wishful thinking I know, but it doesn't work at all - the power supply won't come on - this must cause a dead short. So, tried swapping back the original logic and interface boards, and the drive spins up fine, comes ready and seems OK. I swapped in the control/status panel from the 8xx mb drive - this works just fine, and the one I swapped in has the full LCD and keypad - which work properly. Tried swapping just the interface boards, this time the drive displays a Fault on powerup, and while I can get it to spin like this, it never comes ready. I even tried swapping the firmware ROMs between the boards, still doesn't work. Now, I am imagining here that the incompatibilities in parts are likely because I am using boards and parts >from a different capacity of drive - I know that the logic from a smaller drive would never work properly on a larger one, I was just hoping that it might let me use some of the surfaces. I don't have an SMD interface 1.2gb drive to try this with - so I figured I would ask - has anyone changed the interface of one of these Sabre drives before? I can't imagine how the HDA would be different between a 1.2gb IPI and a 1.2GB SMD, but you never know. I've had luck before swapping controllers between IDE and SCSI drives, and occasional luck going between drives of slightly different capacity. What machines used IPI disks? I know that an IPI controller was available for Sun3 VME based machines (of which I have only ONE). Don't see anything listed in the field guide about a qbus or unibus IPI controller. What about larger Vaxen? -Ian

warning about dealing with Government Liquidation

by wdonzelli＠gmail.com

> Interesting - they do state: "If you still have this item please > contact Government Liquidation within 19 working days to coordinate > the return of this property." So what happens if you do not 'have' > this item any more. This is exactly what End Use Certificates are for. They track the item until it is destroyed. In some cases of the past, with no EUC and the military knocking on the door of someone who scraps an item, the result generally is not horrible - they usually just want the important parts. Extremely rarely does one get the Black Helicopter treatment. -- Will

warning about dealing with Government Liquidation

Hmmmmm 'Sorry guv, it turned out it wasn't what I wanted so I dumpstered it' 'terribly sorry old chap, I've already sold it on' Or any other excuse you care to think up. That's really lousy behaviour - they can't change the rules after you've bought it, surely? And if they're going to add insult to injury by refusing to pay shipping then they can hardly expect cooperation...

Raster Scan (or LCD Panel) Used As Vector Display?

by Billy.Pettit＠wdc.com

Has anyone on the list emulated one of the old vector scan displays on a modern LCD Screen? Did you go through the raster scan logic or interface directly to the LCD panel electronics? Is anybody working on this idea that you know of? It seems like some of the DEC system enthusiasts would be thinking about this since the original Vector devices are so rare. I have a belief that this is an idea that a lot of list members have thought about; but has anyone put the idea into actual hardware? Billy

Dial-up suppliers

by aliensrcooluk＠yahoo.co.uk

Hi, Urgh... my dial-up ISP of about 4 years has recently had a change in policy. Instead of a monthly payment of ?14.99, Boltblue.com have decided to make it free + local telephone charges (to telephone company). This means paying Boltblue nothing and a bill of ?400 to BT :( What a con, are they trying to force me onto broadband?? Gonna go and search online for another dial-up ISP that does the monthly charge thing. Has anyone else experienced anything like this?? Regards, Andrew B aliensrcooluk at yahoo.co.uk

Strange VT50 Decscope

Yes, just like all those other Heath(Robinson)kits produced about that time.

Pictures of My Machine Room (So Far)

by RodSmallwood＠mail.ediconsulting.co.uk

Ah yes trees.. In the UK we have lots of individual trees, a fair few woods and only a few forests. If we go back to after the last ice age (about 10,000 years ago) the reformed land (The land bridge to Europe went) reverted to Northern forest modified by what my college tutor described as 'Mexican bathwater'. Insofar as the gulf stream originates off the coast of Mexico and is warm. This has the effect of changing the mix of native trees from mainly pines to favour more broad leaved species. Oak, Ash, Willow etc. The only thing that prevents most of lowland UK reverting to mixed forest is the presence of man. If some disaster whiped out the human population in the UK then within fifty years it would be back to forest.
