Hi all,
Does anyone have any documentation for this Data Systems 68 6847 video
board? I should have most of the parts to build it up. I'm going to get a
good, high-quality scan of the PCB, front and back, before I do that though.

Looks related to the 6845 variant, but I imagine this 6847 board has more
graphical capability.

On Steve's SU4 copying saga, it sounds like Steve had the
copy-protected, self-booting SU4, while Terry has a non-copy-protected
one. Both existed.
I have the non-copy-protected version available for download on
http://tim-mann.org/misosys.html#down, as a /cmd file that you would
have to import onto a TRSDOS or LDOS 6 disk, say with an emulator
utility. Once you import it, this is the easiest version of SU4 to
deal with.
I also have a copy of a preliminary version of the self-booting SU4
(from Kim Watt's personal collection). I've never seen the final
released version. My notes say that I successfully copied this version
to DMK (using a Catweasel and cw2dmk) and it worked in xtrs. My notes
also say that it was not representable as JV3. So a copy-protected SU4
that works as a jv3 but can't be copied to dmk by jv2dmk sounds like a
really odd duck. I would be interested in a copy of that jv3 to see
what it is and why jv2dmk doesn't work on it -- would also like to
know where it came from.

Hi!
I know it shouldn't be done :)
I don't have any installation media for HP-UX 9.x or older.
I have a disk image with HP-UX 9.03 installed, coming from an HP
9000/425t, and it worked (after minor tweaks) on my HP 9000/375.
Now I'm recompiling the kernel, since some drivers are missing.
I'm lucky, that image has a C and a Fortran77 compiler installed.
Do you know if some HP-UX 9.x (or earlier) images can be found?
I'd accept also DDS-x or QIC tape images...
Thanks!
Hey all --
Recently got myself a system equipped with a Memorex 214 hard drive. The
system's going to be shipped to me eventually, and I'd like to take
precautions to avoid damage during transit. The 214 looks to be an 8"
drive, so it almost certainly requires a special procedure to lock the
heads and/or spindle. Does anyone know what the procedure is for this
drive? (I need something simple and clear enough for the seller to deal
with...) I found the 112/114 manuals on Bitsavers, but I don't know if
these are similar enough to the 214 to be relevant. I can't find much on
these drives at all.
(I'm also assuming the official procedure will require getting the heads to
a safe "parked" position, which is not likely to be possible given the
state of the machine (i.e. unknown running condition). Am I making things
worse by locking the heads at some random position?)
Thanks in advance,
Josh

I got a Digilent at work, and had a lot of trouble getting

Later, for home, I got what claims to be an official Xilinx
Platform Cable USB on eBay, from a Chinese supplier.
It was much easier to get it running, and it has programmed
everything I've tried it on. I make a number of boards
that use Xilinx CPLDs and FPGAs, from the original 5V
Spartan and 9500 to the Spartan 3A and 3AN, 9500XL
and Collrunner II, and it has programmed all of them
perfectly.
I have no idea whether these are really unauthorized clones
or official Xilinx products, but I can say they work, and
are relatively cheap - cheaper than the Digilent.

Subject: Interest in a PDP-8/e/a/f/m 32K RAM kit?
I've heard from a fellow, Vince S., who has created a PCB layout for the PDP-8/e 32K RAM design presented in my article on Tronola.com. He's considering a Kickstarter launch to offer a $95 kit of parts and PCB but is wondering if there is sufficient interest. If so, please let it be known.
Features include:
- Battery backup with estimated 10-year data retention.
- Inhibit on power fail to prevent memory corruption.
- Most of the full size Omnibus board offers a prototyping layout.
- Cooperation with any mix of core memory boards. Switches disable 4K fields.
- Compatibility with Omnibus specs.
- All through-hole parts, for easy assembly.
I'm not associated with the project, other than having published the article and encouraging his efforts. Vince has published lots of PDP-8-related and other layouts on his website and will make this one available as well:

Does anyone have a copy of FLEXTRAN for the PDP-11? I have an
instrument (containing an LSI-11/2) that was designed to work with
FLEXTRAN.
It came on two or more diskettes - one containing the
compiler/interpreter and the other(s) contained libraries and/or
applications.
Cheers,
Lyle
