Bob,
I used an Apple serial card, a null modem cable, and a simple BASIC
program to use the serial port.
There have been some Apple emulators.
Does anyone know if any of them can read Apple 5.25" floppies?
I know that in the evolution of 5.25" drives and densities, there was
the issue of wide heads, wide write tracks, and later heads and
tracks were narrower. Was it that modern heads could read earlier tracks?
Greg
Has anyone got a Compaq LTE 386 that they'd be willing to part with? If
so, please contact me.
Thanks!

The M8190 was salvaged from a PDP-11/23 backplane where it had been
running, so I assumed that it would work in a QBUS setup. Is there an easy
way to tell whether the card is really Unibus or QBUS?

Actually a PDP-11/84 uses a Q-Bus CPU in an adapter of some sort, same with
the memory. My concerns with what I see listed above are if the memory
will
work with the CPU (did it come out of the same system?), I don't have time
to check the part number. The other concern is, since you're wanting to
run
2.11BSD, is the disk controller supported?

Hi
Even for a sine wave, the brick wall filter would be difficult
to create. You need a little more room.

The thing to consider is that we are not sampling a "square" wave.
It is a variable pulse width digital signal. The only kind of
processors I know of that could handle this from a port is some
of the latest DSP chips. Using a PC, even one like our ( AMD )
latest Opteron wouldn't do well since it is so highly pipelined
and unpredictable in execution speed at this short a time
interval.
There are a number of DSP evaluation boards out there that places
like ADI and TI sell that could be made to handle this task.
Of course, a simple pulse width counter on the front end could
simplify the sampling process.

What you're trying to do is find the edge position in the presence of jitter
though it's more of an issue with floppies that have belt-driven spindle motors.
It also helps detect runt pulses in sector splices.
Hi All,
Got a whole pallet load of old documentation for $2 at the local University
Auction.
Some Stuff I'm keeping but if anybody is interested in some of the other
stuff, its your's for the cost of shipping, probably USPS media mail, or UPS
at your choice.
Free to good home:
Evans and Sutherland PS 390 Documentation Set (circa 1987)
4 Full size Binders including Hardware and Software documentation.
OSF/1 manuals all topics about 40 or 50 manuals all together. I'll keep a few,
but the rest go.
Digital Unix manuals, about a dozen, all topics. most are the usual software
documentation.
Digital VMS 6.2 manuals almost a complete set. These are not the big "grey
wall" of dec binders but the newer paperback manuals.
All of the manuals are in Great condition. It looks as some have never been used.
I will have a list of the OSF/1, DEC Unix and VMS manuals in the next few
days,(as I go through them) but if your looking for a special one, contact me
off-list.
Remember as I'm doing this for free (ie cost of shipping) it might be a while
before I get them sent.
Also, the last time I did this, I got burnt by some on this list who never
sent me the shipping costs, so this time shipping costs up front.
Thanks
Tom Ponsford

Hi all
Forgot to mention my Zip is 85630 (SE Arizona)
The Evans and Sutherland manuals have been spoken for:
Remember first come first served with priority to those who take the most stuff!!
Ok, here is a partial list of the DEC stuff:
The VMS stuff is too much for me to list today, besides most of it I put in my
storage. Its about 4-5 of those plastic 25 gallon storage boxes.
But here is the OSF and DEC Unix stuff:

Hi all,
Any ides if the keyboard and mouse needed for an SGI 4D/25 was used on
any of SGI's other models?
A machine just cropped up for free but it's got no mouse or keyboard
with it. The keyboard socket on the machine is a 9-pin D-type female
(umm a B-type in correct terminology I think) - I'm assuming the mouse
plugs into a port on the keyboard, rather than tying up one of the
serial ports on the machine?
Oh, the root password isn't known either... but I'm assuming there will
be ways around it on a machine this old.
cheers
Jules
