Hi,
I knew ST-251-0, ST-251-1 drives for ST506. Some time
ago I've got a ST-251 labled "MLC-1". Does someone
knows what the MLC stands for? What is different to
the other ST-251 variants? It looks like a regular
ST506 drive.

There is one quite inexpensive on Ebay right now. Looks to be a match
for the system unit at the CHM as well. Maybe they need a spare. I
don't know if they want parts machines or not, but for the price it is
almost tempting to pick it up.

Hope Christmas brings everyone a lot of new toys. (as in old ones).
Thanks
jim

Looks like a straight image for a 1.44 what we call "stiffy". The 522
is the version of RP06.
Google leads me to http://www.corestore.org/rp12.htm so you already
know what it's for :-)

yes I can... it got LIFTED! Ripped Off! Stolen! Bummer eh?

Could you rephrase that?
it appears the pen kit for our plotter got listed before we had
it glassed in living the glassed in display a areas if anyone has a
calcomp box with the solenoid and pens that is extra to their needs
please let us know

Surely there is a copy of CalComp Host Computer Basic Software (HCBS)
around somewhere that talks to the XY11. After all the Calcomp is pretty thick.
All it can do is move 1 step at once, well it can do diagonals as well,
but pretty thick...

Back in the late 70s early 80s one of Dad's work colleagues came up with this circuit for interfacing
an IBM I/O Selectric to a microcomputer. We had one, which we planned to use with our Fairchild/Mostek
F8 development board, but it never got done - my brother and I wanted a computer with a screen, not a
printer! So we spent our pocket money (and Dad's too) on an S-100 kit system, but that's another story.
Recently I found the only remains of our I/O writer, the platen. Sadly I think it must have been junked,
the platen being kept to roll out photographic prints in Dad's darkroom.
I just finished scanning, cleaning up the degradation and turning the circuit into a PDF. These days an
Arduino or RasPi would be a simpler and more flexible way to go, but I hope you find it interesting
looking at how it was done with TTL and discrete components.
The circuit was designed by (I believe) Neil Taylor, possibly with the help of Derek Williamson, both
brilliant IBM Australia CE's. I know my dad always spoke very highly of them.
It's an 8-page PDF at http://web.aanet.com.au/~malikoff/misc/IBM_IO_Selectric_interface.pdf

I had the large ibm calcomp plotter if big wide one we have the same
... it is in the hp display case at smecc museum
there was a fortran graphics text book we had adn I had gotten with a HP
3000 and it had a interface board ( parallel interface?? too many
years)
I made it plot squares etc .. as I remember the hp intrinsics may
have had some support for this..
once I did that i put it aside and went back to playing with the HP
multi-pen HP plotters we sold back them at Computer Exchange Inc.

The book 'The Minicomputer in the Laboratory' by James W Cooper covers
using an
X-Y plotter with an 11/05, and has assembly listings and a whole bunch of
related
stuff about scientific plotting. Also a lot of info on using the LPS-11
too.
There are plenty of copies out there and quite cheap too. It's an
excellent book
and could be of use to you.
Steve.

Suppose so. They took a complete disc, sector by sector, and wrote it as a file.

Hey everyone, just got my Apple1 powered up!!! The PIA is hot to the
touch, I heard they run hot, how hot is too hot??
Looking for an Apple II keyboard to convert for use on my Apple1. Anyone
have one for sale or trade?
Thanks!
