Hi, I have found your message from 2006 y. about science fair 200-in-one
manual. cat no 28-249
I have found just this model in the basement and i like to give it to my
children. however it has no manual.
I will be grateful if you could send me an electronic copy of your manual.
I will be able to send you scans of Marklin (germany) catalogue of
Trains 00 and 0 gauge and some model cars from 1938 y. if you wish.
Best regards

I'm trying to make a pathway into a storage unit prior to emptying it. The
following are a list of items that were in the way and I don't think I'll
need. If you have any questions or interest, please feel free to contact me
off list.
BA11-NC box has 11/23 sticker on it. No black case or white front panel, but
includes the switch panel. Was working, but selling as is. This it the box,
backplane, H786 power supply and switch panel only. I have boards here, and
can configure a set to your specs if requested.
EECO INC 2001-4 paper tape reader, looks like a RS232 interface. No idea of
the history or condiction.
Rokke Data table top box containing ps and 2- Seagate 41650N drives. Can
sell with or without CQD-220/TMS interface and cables.
Was working, good condicition.
Seagate 94196-766, condiction unk.
HP94758E in sealed static bag from vendor, but sitting here for a few years.
several Micropolis 1355 drives,pulled from working systems, but sitting for
a while-possibly stuck now?
Thanks, Paul
Hi folks, does anyone in the Bay Area or California have a big "multi
color" iMac G3 collection (from late 1990s-2001 or so)? A guy is
asking the Digibarn about this but all we have is one Bondi Blue model.

Hmmm. What is a CXY08-M good for?
Unless you have an s-box enclosure, I'd say it's probably only good for target practice. ;-)
Shamefully, I've never been curious enough to attempt to use one on a PDP-11.
I jumped right from the DLV11-J's to the Emulex CS02 (quad 16-port w/DMA)
and then to the DHQ11's when I moved into a BA123.

There are folks out there that can't even give away their DHV11's.
I always get a chuckle out of seeing folks listing DHV11-M's on e-pay for $50.
. . . which reminds me, I should start digging through my inventory,
and dumping the CS02's and DHQ's that I have, since all of my I/O
is now via a lowly DELQA, and a hardware LAT <> TELNET bridge.

Without documentation indicating that the equipment presents a balanced load,
it should not be assumed that it will. If the equipment power lead has a
neutral then it is probably not a completely balanced load and the neutral
will probably need to be connected. The consequences of not connecting the
neutral could be excessive voltages getting applied to some parts and reduced
voltages getting applied to other parts of the equipment. This is not good.
If the equipment does always present a balanced load, it may allow the option
of connecting it in wye (star) or delta format and the supply voltage required
would be different in each case.
To clarify the voltage specification, there are two different ways of
specifying the voltage in a three phase system. The "phase voltage" is the
voltage between any one of the three live conductors and the neutral conductor.
The "line voltage" is the voltage between any two of the three live conductors.
The line voltage is sqrt(3) times higher than the phase voltage. The line
voltage provided by the supply should match the line voltage required by the
equipment. The same applies to the phase voltage, although if one matches, the
other will also. Phase voltage doesn't really have a lot of meaning for a
system without a neutral and such a system should be specified by line voltage
only.

Every blank that I place in the Canon AS-100 reports an error.
All of these disks are new-old-stock. I know they work in other units (Commodore 128 for instance).
Even the Tandy 2000 can format a standard 360/400k disk to 720k. I've tried those and high density floppies w/no success. What haven't I done?
Does anyone have a spare front door for a BA213 cabinet taking up space? PLEASE NOTE: this is for my private collection, not the Living Computer Museum. I have a MicroVAX II that's missing the door. It's not one of those things where I want to spend a lot of money, but if you have one just kicking around and would rather have a six-pack of good beer....
I'm in Seattle - shipping from e.g. Europe might be a bit excessive. Thanks - Ian

Hey folks. Does anyone know offhand if it's possible to model the
hysteretic behavior of a neon lamp in ngspice or gnucap?
Or, better yet, can anyone send me a working model or subcircuit? =)
Thanks,
-Dave
