We applied some Magnetic Developer to a piece of LINCtape and can see the
tracks. You can clearly see the extra space between the Mark and Data
tracks. When we can get access to a microscope with an attached camera we
should be able to see the bits.

I am looking for schematics or any documentation for the LA180
interface for the PDP8/e. A scan would be great. I want to see if I
can use it to interface to a Centronics interface printer.

OK, I have verified that all the tools to run and re-build MACRO-11 do in fact
run under vanilla V6. (Which is no big surprise - I'm very familiar with the
changes to MIT-V6+, and most of them were in area like the terminal driver,
etc; there was no reason to change any of the file-handling primitives.
Here:
http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/macro.tar
is a tar file with the whole works, along with the MACRO-11 source. Just
download and explode, and read the 'README' file to start with.
It does not yet include the source for the 'bind' linker (used with the .REL
files that MACRO-11 puts out), because that's in BCPL, and there's no point in
adding the source for that until I've put the BCPL compiler itself out, which
I will do once I can confirm that it can correctly compile itself (it's
written in BCPL) and re-create itself.
If the first person to try MACRO could send me feedback, to see if the whole
process works, I'd be grateful.

I would also be very interested in getting a copy of all your BASIC and MACRO-11
sources. I can handle most of the usual media, but pulling it off an FTP
site might be best.
Thank you very much for thinking of us.

I've got a Panasonic JU-455-5 AAG (5.25, 360K) that I'd like to use in a
Kaypro 4. I've worked out the configuration of the drive based on a
snippet of info on the net that had some jumper settings, but I can't get
the activity light to operate. I've set the configuration to use the
light when either motor on is detected, or the drive select, but neither
seem to work. I figure a "real" manual on the drive would help.
Note that the drive seems to operate without issue other than the drive
light. Boots, etc.

Tnx!

That is the goal.

_Iff_ the existing binaries won't run under vanilla V6:
For me, going the Apout route would require learning about Apout. Bringing up
the MIT-V6+ under an emulator (so they could be run) would be a _lot_ less
work, since I'm already intimately familiar with it, and I already have
vanilla V6 running under an emulator (which I could use to produce a MIT-V6+
kernel that would boot under the emulator - the existing kernel images
wouldn't, they use disk controllers that the emulators don't support).

That's there too - that's being discussed on the TUHS list. See the archives.

Interested in just the BASIC, or in the whole package?
For those who are interested in running any of this stuff on a UNIX of some
sort (as opposed to, say, taking the BASIC source and editing it to run under
some DEC OS, using the pre-existing MACRO-11 on such a system), there are
dependency issues one is going to have to deal with.
That's because the MACRO-11 is written in MACRO-11, and the BCPL compiler
(which one needs to compiler the linker) is in BCPL. So before either one
can be assembled/compiled... one needs a working assembler/compiler (as the
case may be), along with a linker. Can you say 'dependency loop'...? :-)
I _do_ have working binaries (I think) for the MACRO-11, BCPL compiler, and
linker.. but they may or may not run under vanilla V6 (they ran on the
much-modified MIT-V6+, which is kind of an early PWB with a lot of MIT
additions).
Let me try them and see if they run under vanilla V6 (which I have running
under Ersatz-11), and if so, then I can hand out the whole package. That all
will take a couple of days to deal with.

Hello All,
So maybe not quite classic but I believe in the vintage time frame - does
anyone, ideally in the greater LA but even SoCal area, have a line on an
Opal White 22U Compaq 9000 Series Rack? This is the half height rack not the
full height 42U which seems to be everywhere (you can see pictures of a
similar unit here:
http://www.vcfed.org/forum/showthread.php?55953-Compaq-22U-Rack-9122). I
don't have enough space for a full height one and the half height fits the
bill nicely. TIA and sorry for interrupting the DEC talk!
