Hi friends,
Now that I have my glorious disk toaster (2D model I think, says "2D" on
the drive levers), I want to build a controller for it. I found pinouts and
some description of the media organization here:
http://bitsavers.trailing-edge.com/pdf/ibm/6580_Displaywriter/S241-6248-3_D…
I'd like to actually store data to these disks in the same manner the
original systems did, and I'm proficient in hardware/firmware. Has anyone
made a controller for this already? How about emulating the filesystem?
Any help is appreciated, and I'd open-source whatever I make (PCBs,
firmware, etc.).
Thanks!

Hi everyone,
I heard Kemners Surplus in Pottstown, PA was going away so I decided to pay
them a visit. I'm taking pictures of as much vintage computing gear as I
can as we speak. I'll be here until they close today at 5pm EST, so if you
see something you like feel free to give them a call and I'll help them
navigate.
Photos updated as I walk through, here:

If you see something you like it'd be great if you could check if I'm
interested first until I'm finished today. ;]
Hope this helps someone, they shut down soon!

Are you referring to MonoKote (www.monokote.com <http://www.monokote.com/>)? That looks perfect for repairing the gouged bed of one of my 9872C plotters. Is a hot air supply suitable for applying the film, or did you use their heating iron? I'm guessing a bit of pressure to adhere the film is necessary?
Oops, this was meant to go to the list _and_ William. Sorry for duplicate Will.

Maybe, maybe not. And there they are, as opposed to being mythical, somewhere else.
Anyway, if someone was to go to Kemners and offer $10 a box for all 4, arguing that
"they are pretty far gone, jam city, dusty, in a mess, maybe some blocks are OK, etc."
Then I'd pay for them and pack & postage to my US reshipper in CA. At this address:
Guy Dunphy
3503 Jack Northrop Ave
Ste J8637
Hawthorne, CA 90250
USA
And then be facing the postage to Australia too. Hence my low offer.
Reason: As part of the Australian Computer Museum Society equipment dispersal, I have
an IBM 028 and three IBM 026 card punches to restore. Eventually.
Plus that Documation TM200 card reader. Which I'm still seeking a manual for btw.

That's a lot of visual fun, thanks for the photos. There is NO SUCH THING in Australia.
There were still a small number when I was a child (1960-70s), all long gone now.

Too bad he wants $25 a box. And it's on the East coast, not West coast near my LA reshipper (to Australia.)
And I'm near broke again, after this:

Of all machines I've used, the beloved Atari 8-bit is most vocal. It
has the feature of 'i/o noise' by default. It can be disabled with a
Poke, but every kind of io has distinctive sounds and actually
represents the data being sent/received. If you disable it and crank
the volume on your TV, you can STILL hear it, but very muted. I think
this feature was created to conceal this fact...
It isn't just the Atari8 that has this 'feature' in its muted version,
all of the RF-TV-type machines from the 80's produce it. In theory, I
think you could snoop the actual data, Tempest-like, using some radio
gear.
One gets very attuned to the noise and can tell the type of data being
sent, (Text, vs Binary, for example) by ear. Of course, tracking
noises from floppies and hard disks are also very useful indicators.
In the 90's I got the hpfs386 driver out of a warp server pack and hung
it on my warp 4 client. I LOVED hearing it hit the drive at boot. Boy
howdy what a performance increase that gave.
Best regards,
Jeff

Hi folks,
I think the NI Ethernet device is ready for some real world beta
testing. I have put up a page here with details about how to build SIMH
and how to install the "NI" ethernet drivers and TCP/IP software here:
https://loomcom.com/3b2/networking.html
If you're interested in helping out, you can build the current "3b2-ni"
feature branch from GitHub and give it a test. If you run into any
problems, I'll walk you through how to do some debugging and get logs
for me to look at.
If you have any questions or need any additional help, please don't
hesitate to email me!
Best Wishes,
-Seth
