That's what I'll call it, since I don't know the correct term Osborne
used. It's the plastic plug with pins that jumper the external video
card-edge port on an Osborne 1 portable. Without it, the Osborne
either goes into external video-only mode or, according to one doc I
read, it will damage the hardware.
One of my O1 machines is missing this part. Does anyone either have a
spare one or know of any plans out there to build your own?

if that matters, and that's all I have of an MDS system). The listing calls
it a Shugart 801. I seem to recall Fred stating that a S* 800 was a *good*
drive to utilize w/some peecee disk controllers.? Is an 801 also *good*? I
e-mailed the seller intending to grill some info out of him.

Here is a set of pictures picture of the jumpers from my MDS drive with
Shugart 801's in it. Do they match up with yours?
I don't have the system it came from only the drive. Note how drive 0
jumpers differ from drive 1 significantly. You can see from the pics that
the outside of the case was pretty dirty, fortunately cleaned up nicely.
The inside was just fine, no grime.
I did not look up the jumpers in the manual, just took the pics for future
reference.

what about using SD cards? someone told me the innards were
better than the ones they use in USB drives and other have told me there is not
much difference?

I'm still using my 256 and 512MB flash drives. But you have a point;
the consumer flash USB drives are not known for their robustness. When
customers ask to have data returned on USB flash, I balk a bit, and
insist on sending along a CD or DVD with the flash--and then hang onto
the data for at least 30 days.
Just like floppies, storage environment and handling means a lot. If
you're used to carrying a USB drive around in your pocket along with
your keys, you should probably have a backup of that data somewhere.
I mostly find pen drives useful for sneakernet and substitutes for CD
ROMs on systems that lack drives.
A useful comparison between SLC and MLC flash:
http://www.supertalent.com/datasheets/SLC_vs_MLC%20whitepaper.pdf
Speaking for myself, I have data backed up in several places, one of
them being off-site in a vault, against the day that we have a sudden
300m rise in sea level. :)

Thanks... that was what I was afraid of.
As some of you know I do some video work
and storage is a big issue in the camera.
most of my larger cameras use mini DV.
BETACAM or DVC-PRO... but all that is
going away in favor or memory storage devices.
Big concern.. as with tape I shoot injest the tape into the
edit bay. toss tape on storage shelf and have the orig. saved on tape
and .... the edited version can also be saved back to tape as
well as saved on the network attached storage units.
I fear in the future having memory card crap out !

Same cheap shit as cheap USB drives. Especially MicroSD.
If you wane be (halfway) save you have to go for industrial grade SD
cards. Depending on size you will have to pay 10 times as much per GB
compared to consumer grade stuff.

How does this work ? I assume it is 90 column right ? You have a
character wheel then another wheel that I assume goes to 90 with stops
along it. Four latches but, they cant be in the same positions. What do
'S' and 'T' stand for ? Side and Top ? How do you advance the card ?

I just happen to have one of these (unlike that ratty specimen it's in
pretty well mint condition aside from a dried-out ribbon); for sale if
anyone has ~$100 & S to throw away ;-)
Remember the old Dymowriters? Same idea.
1 - Pull out card holder.
2 - Insert card.
3 - Dial letter to punch (and print!) and press (wait for it...) PUNCH
- card advances to the next column.
4 - Repeat (3) until End Of Card.
5 - Remove card; goto 1 until Finished.
The wheel with levers sets the Tab stops; the T button (you guessed it ;-)
Tabs to the next space, and speaking of Space I'm sure you can guess what
the S button does...
80 columns BTW...

We removed the 709 power supply and checked for physical damage.
Everything looked OK.
We reformed all of the capacitors in the power supply. All worked OK.
We attached a resistive load to the power supply and measured the
output voltages. All looked OK.
The power supply fan was sticky so we sprayed some WD40 in the end
bearing to free it up. It is noisy, but it works OK a few seconds
after it is powered on.
We reinstalled the power supply and connected the AC wires.
We connected 110VAC to the power cord to the 841A power controller.
We could control the power state with the power switch on the console.
We connected the remaining red/white wires to the 709 power supply and
found that all of the chassis fans work OK. Some are noisy though.
The hour meter runs and we add a few tenths of an hour to the 40,163
hours already on the system.
We connected the DC wires to the 709 power supply.
We turned the power supply on for a few seconds at a time and measured
the voltages on the chassis test points.
The voltages looked OK and some lights on the console turned on.
We tried the basic Examine/Deposit functions, but did not get the
expected response.
We can turn the PRGM STOP light on and off with the I/O RESET and
START switches.
With the REGISTER DISPLAY switch in the API position the REGISTER
lights flicker.
The rate of the flicker can be controlled with the REPEAT SPEED switch.
Later this week we will do some basic debugging to see if any of the
processor is working as expected.

Hi all --
Earlier this summer I picked up an IBM 5120 (5110 model 3) in fairly rough condition in the Grand Rapids, Michigan area (where my parents live -- they kindly picked it up for me and stored it in their garage but now I need to make it disappear :).
I bought it because I have a 5120 that needs a few parts (keyboard, monitor, ROS and CPU boards) and I'll be taking those back home with me. The rest of the machine is up for grabs -- anyone near the Grand Rapids area need any parts? I'll be in GR until Jan 1, so if you want 'em, speak up soon.
Thanks,
Josh
I had some time last night so I spent several hours digging through documentation and sitting at
the console to see if I couldn't make some progress.
First of all, I figured out how to obtain the ethernet MAC address:
show ethernet-address
What I had to figure out that I had to be at the FEP (Front End Processor) prompt and not the
LISP listener since that command is an FEP command. So now my home network is configured
for when I get the Symbolics configured enough to enable TCP/IP (or as Symbolics names it
IP-TCP).
I also discovered (shouldn't be that big a surprise) that Genera doesn't really use configuration
files. Everything is stored in the running LISP state. One thing that has to be remembered is
that the entire LISP state needs to be saved when making configuration level changes (or
installing new software). Just because it's on disk doesn't mean it can be used.
I'm going to see if I can't get a bit further today.
TTFN - Guy
