I'm trying to figure out how to created and load a "soft character set"
into a vt220 terminal. These documents:
https://vt100.net/docs/vt510-rm/DECDLD.html, seem to talk about how to do
it, but I don't follow this well. I'm guessing the fonts are made up of
escape sequences. Then I guess they are loaded by simply printing them to
the terminal. If that's the case, where are the examples of such
Playing around with vttest, there's an option to "Test Soft Character
Sets" in the "VT220 Tests" menu. But I get the error message "You did not
specify a font-file with the -f option". Where can I find examples of
Putting these together, I'm guessing what vttest wants is a file
containing sequences described in those two documents. So, where do I go

Can't find very much information about the PDP-11 System Identification Register : RO at 77777764
The occasional processor handbook says not implemented or the 11/xy reports num.
Interogative : information sources, e.g. a tabulation of known values
Is there any interest in my working 11/23+ system? I rarely run it any
more, but don't know what it's worth.
Corporate cabinet, VT220 console, 4 MB RAM, two RL02 drives (RT-11XM,
TSX-Plus 6.50), interface for 3.5" floppy drive, 16 serial ports.
Located in south central Missouri so pickup would be greatly preferred :)
Earlier this December I got an Altos 386 series 1000 with lots of
documentation and some installation floppy disks and one tape. I must say
that it's an amazing machine!
I'd like to reinstall the os but I have two problems:
1. It can not access the floppy drive. I tried it with another one, but
still no joy. Does anyone have any schematics of the motherboard? I ordered
a new floppy controller but in case the controller is not the faulty piece
I'll need some schematics to track the problem.
2. I could clone some of the floppy disks on another computer but not all
of them. I also found that the tape is overwritten with something else.
Does anyone have these installation media? I'm missing sdx v3.6s0, aom menu
shell v 3.0s2, Altos system v rts upd V5.3es2 and the tape Altos system v
rts v5.3eT2 (utilities).
Anyone know how to contact the Altos folks? Maybe they still have and are
kind to share the installation media and the schematics.
I have cloned Altos system v rts v5.3es2 (root), Altos multiview 1.6.2s0
two disks and the HDD. Btw, none of the Linux filesystem modules could not
mount the hdd, therefore I created one based on fuse. If anyone needs such
a thing you can find the srcs here : https://github.com/bog-dan-ro/altos .
Happy new year!
P.S. I contacted Al from bitsavers, and my floppy disks clones will land to
his collection (http://bitsavers.trailing-edge.com/bits/Altos/386-series/)
P.S.' Al's tape image clone has a strange tar like format, does anyone know
what's the exact format? I'd like to create a tool to extract them...

Happy New Year everybody.
Pleased with my success at getting a QIC02 drive running through an MTI
MSV05B on my RT11 system today, my jaw dropped when I did a DIR MS0: and
saw the pulley turning and the tape not moving, as liquid rubber
starting accumulating on the drive belt!
It turns out that the rubber wheel inside the TK25 cartridge had melted.
OK, the cartridge goes in the bin, but has anybody found a way to clean
the residue off the drive without damaging the drive belt?
As always, any advice (other than to dump the whole thing :-) )

Probably not cheap unless you get lucky, but an excellent choice would
be the Toshiba P1351 (not to be confused with their later 1351 laser
printer) or the narrower P1340. They are 24-pin dot-matrix printers
that feature downloadable fonts and both serial and parallel interfaces.
I got my P1351 in 1984 and it has served me well. I created (OK, stole
from Xerox) a double-high double-wide font that I used for printing box
labels when I moved.
You could also do really nice graphics with it, at a resolution of
180 x 180. CCSI (Cerritos Computer Systems Inc.) wrote a driver for
the P1351 for their CCSI-Plot (Plot-10 compatible) plotting package.
I can provide a copy of the software (in Fortran for PDP-11) and scans
of the manuals for both the software and printer, should you get one.
You can still buy ribbons for it, so it would be a really good choice.
Amardeep S Chana,
I have the Joel Owens’ Z80 Master Controller Board that you asked about back in October of 2017. I have a folder of collected documents. If you are still interested I could share those some place.
Broken monitor hinges. All sort of madness. No screws. No structural integrity whatsoever. But the sucker works. Assuming you glue it all to the point it'll sit up strait on it's lonesomes, plan on an external mouse and keyboard (kb works though afaik).
