I. It would not have fit in my garage much less my house. II. My dedicated 220V Line is being taxed enough as it is. III. I was alone and far far from home. IV. As I approached the dumpster the manager of the property disposition started chasing me with a broom. V. I've already rescued a Data General Nova 3 which is much more fascinating to play with.

Ah, but do you have a trailer hitch........ Be sure to bring back the dumpster.

Speaking of searches, I have been searching and searching for an Apple III motherboard. Mein ist kaput, I am afraid. Anyone have a spare they would like to part with? Louis

I had a miniscribe 6085 in my 286 in the late 80's. It is an MFM (ST506 interface) drive with the same parameters as the Seagate ST4096. I think cylinders are 1024, heads at 9, and sectors per track at 17. The RLL model would have an 'R' appended to the model number and would have 26 sectors per track. You might be able to run the RLL model on an MFM controller as the difference between the two variations is mainly the platters. Rarely are the drives much different. I ran a 3650 for a couple of years on an Adaptec ACB4070 bridge controller and believe it or not they worked perfectly though they weren't rated for RLL linear density. Despite thier poor reliability record, I still like Miniscribe drives. They sound neat. "Peeep wobble wobble Peep". Western Digital bought what was left of Miniscribe and produced some really aweful drives when IDE was beginning to really catch on. I remember stacks of dead WD 40mb 3.5" drives at a company I worked for in 92/93. We called our 'boneyard' "The Closet of Shame". The drives were an MFM mech with an IDE board attached. They used stepper actuators and sucked eggs for reliability. They did sound neat though..... -- ----------------------------------------------------------- technoid(a)cheta.net -----------------------------------------------------------

I remember 3.5 " WD types that were mounted in a 5.25 bracket. At some point in their lives they would generate a lot of bad sectors in the outer cylinders. (You would expect the inner cylinders because of the higher bit densities). To fix the problem: partially unscrew the drive from the bracket (with a torck-tool) an fasten it crosswise (like you would fasten a tire). The harddisk would happely run another couple of years. Some supplier threw the bad ones out, and we asked the corpses for socalled educational purposes but quikly repaired them instead. Sipke

Since your only response so far was so rude, I decided to see what I could come up with. The system might not be old enough to be on topic, but it does look like a nicely constructed piece of gear. Unfortuantly the only thing I was able to dig up was a Systems and Options Catalogue, but it pointed me in the right direction. The full capacity is actually 192MB apparently (it's also listed as 128MB), though I wouldn't recommend trying to accomplish that. This system uses the same RAM as some of my Alpha's, which means it rather expensive, unless you find it used. You need True-Parity 72-pin SIMM's for this system. I don't believe EDO will work. I know the Alpha's that use the same RAM are fairly picky. OK, I see such beasties are actually advertised as being eventually available. Interesting. You might be able to find a Pentium processor if you're very lucky, but I don't believe you'll be able to find a Alpha processor for it, and if you do I imagine you'll be very limited as to what you're able to run on it.

Compaq SLT PSU dead. Power DC plug is DEATACHABLE from power brick, model number: 2687. Other SLT PSU bricks aren't deatachable. No signs of power and fuse not blown. Uses compaq's relabeled common UC3842 pinout PWM ic, yes I traced enough from the UC3842 datasheet. Single chopper tranny is MOSFET (BUK456-800A by philips). R512 and R500 are now ashes. I need the resistor values on these. What good subs for this MOSFET? And any gotchas? I have looked up on this specs on this transistor but I'm not so sure and *very* diffcult to buy that correct part so I need to sub this transistor out from bunch of choices that has 1-MOSFET PSUs with different types of 8pin UCxxxx PWM on it. Everything else are fine. Cheers. Trying to get SLT 286 going because other bunch of SLT 286 and SLT 386s/20 was given away with own working bricks. Those working bricks was not correct model like this kind I have in pieces and this is remaining SLT 286 I want to keep. Wizard
