Ah, cool thanks!
I'm interested in storing arbitrary files in the manner close to the
original as possible. Sounds like the extent list and allocation map would
be useful for this; not so much the document content format.

Ok, are there command/response listings for these controllers, or one for
this exact unit?

Hi Ali,
I'm planning on a USB controller, but I've seen ISA projects that are also
microcontroller based so I think it wouldn't be awfully difficult to
replace the USB data pipe with an ISA one.
Zooming out, I have a list of USB controllers to build:
- Kennedy 9800 tape drive
- IBM 6360 8"
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:

True, there were large reels on a rack, most were educational films.
There was a room dedicated to tube radios, most were in very rough shape

Also a room with reel-to-reel audio decks from AKAI, Teac and other brands

They have until the end of June 2019.

More photos posted to the album with some NIB DEC boards, look like a
motherboard and CRT board, two of each.

They have probably 25 boxes of 10, 8" DSDD floppies each that are still in
their sealed packaging if that's of interest!

Oh boy, how did I miss that someone has created a front panel PCB layout
for a PDP-8/e?
Can you ask Vince to share that design please?

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'd love a link to the images of that decgraphic brochure when you scan it!

Serial flash has an endurance between 10K-100K writes per cell so I think
that would break down quickly. Wear-leveling on a serial device would be
very slow...

If you want the real deal you can always make a driver out of a bunch of
H-bridge ICs and an old core plane. I'll skip suggesting you weave your own
core...

Texas Instruments' MSP430 MCUs use FRAM. This one for example:
http://www.ti.com/product/msp430fr5969 costs ~$2.30.
You could do some emulation in the same package, too. Not sure what your
speed requirements are of course!
