My employer sent me out to a training class and I had to stay in a hotel for two nights. Could not sleep because I was not accustomed to the silence! Then later on I upgraded the drive to a Seagate ST-4096. What a big difference in the noise level. One good thing is the larger drive helped keep my bedroom warm in the winter.

If I recall correctly, the twist in the large cable simply changes the drive selector so you wouldn't have to mess with the jumper on the drive to specify drive 0 or 1. IOW if both drives are jumpered as drive 0, the twist would change the selection for one of the drives to be drive 1. You could instead have no twist at all and use the jumper on the drive to specify drive 1.

Back in the late '80s early '90s I used to rebuild hard disks in a clean room. I remember the ST225 and ST251 drives and I think there was a ST270? which used RLL as its data writing method. I might have the model numbers wrong there as it was a long time ago. We used to replace the platters, heads, motors and re-write the servo. Low level and then high level format them in DOS for a boot and test. We had a dedicated machine to thrash the refurbished hard disks on (after a lengthy spin up soak test) before we stuck them on a PC for the final formats and testing. To lower the heads back onto the media we made head spacers out of clear plastic which we gently rotated with tweezers to lower the heads down. All this in a face mask and paper suit with cold filtered air being blown onto you at a rate of knots. The 3.5" HDDs with multiple heads and platters were the trickiest to do.

If I were you, I'd put the over-engineered MFM emulator into the over-engineered AT&T Unix workstation. Let AT&T Unix be reliant on modern Linux for its storage solution. It seems fair. Linux basically made all those old Unix servers obsolete. The least it can do is help an aging Unix machine live again. IMO the "purity" of the 5170 is just a bit silly. The idea that these machines never had some other component in them, and you had to maintain some semblance of using all IBM parts is just... wrong. People have been upgrading, expanding, and putting new components in them since they were created. That's why IBM put slots in the computer.

So... now I've used that emulator for my Myarc Geneve 9640 with a Myarc HFDC controller for some time, the latter is supposed to support up to 134 MB per drive according to Myarc (up to 8 heads and 2048 cylinders), but a minor modification makes it work with up to 16 heads. There's a file system limit though, so the limit is at 250 MB per drive, i.e. half a gig with this emulator. I was kind of excited since it was pretty much experimental; I'm not sure anyone have ever gone that high with the HFDC before, but it works absolutely perfect! Until then my largest drive was a 44 meg Rodime, which isn't too stable anymore by the way. I'm equally impressed with this emulator and I don't regret for a second that I purchased that one from David... it's absolutely awesome how it works! 😀

This would be pretty cool emulation for other channels like Curiousmarc channel.

Adrianne - SSH is now built into Windows, no need for puTTY anymore, just run the command prompt and use ssh like you would on any linux machine. It's pretty awesome.

You could imitate what Craft Computing does, where at the end of each episode he does a little mini-review of a new beverage he's trying. Could do something similar with the candy.

I am with you on the hard drive noise thing.. I was really happy once the whine was gone. I am however ok with the seek noises. I rather enjoy the clunks of old scsi drives.

I wouldnt have used large caps to allow for some shutdown time. I'd just used a couple of 500mAh AAA batteries, low capacity ones that you use in DECT phones. Standard, replaceable, rarely leak (they are such a low value I have never seen one leak) and a simple step up to 5v will power the thing long enough to shutdown. Just a gentle trickle charge to keep them topped up, they will last for years. I'd only do this for cost reasons and the fact the caps will kill the board when they fail.

I appreciate this technology, but personally I prefer to stick with an XTIDE and CF card setup in my 5160. The CF card setup allows me to swap out my entire DOS setup in a very easy and obvious way. In other computers where it wasn't as easy to switch over, or with fewer slots such as a 5150, I could see this being more useful. In my 5160, I left my half height ST-238R in place, unplugged it, and set my WD1002a-wx1 controller to disable the BIOS. This way, the hard drive is still in there ready to go with a few simple changes, and I don't have to store it somewhere else away from the computer itself. I do miss the noises of the old hard drive, but since mine is working, I decided to park it and leave it in place so as not to wear it out too fast.

I would definitely save that emu for the Unix machine. The IBM will do just fine with the Emu hardware it has.

The Digital Equipment Corporation PDP-8 would never have been factory-equipped with the Shugart Associates ST-506 hard drive, as it cease production before the ST-506 was released.

Wasn't the twist thing in the cable because all drives jumpers were set to be the second drives and the twist was there to make it the first?
