So, I turn on the computer this morning, go to www.cnn.com to see the
latest Britney Spears news ('cause CNN reports on ALL of the important
stuff like that) and what do I see on the front page?
A Commodore 64 story!

My father just rescued a Hazeltine 1200 from a scrapheap for me. I know
nothing about these. Could someone give me some pointers to
information? Thanks.

I'm trying to have a clear out and I think it's time most of the
legacy Mac stuff went.
I have:
- 2 LC 475s (one dead, one alive, as far as I can recall)
- one PowerMac 6100/66 (runs but has a blank hard disk)
- one Beige G3 minitower (300MHz, CD, Zip, 8GB HD)
- UMAX PPC604 Mac compatible minitower machine
I've also got at least 1 21" mono Mac monitor with accompanying mono
NuBus graphics card, 1 or 2 14" Apple colour monitors, and a couple of
boxes of classic Mac apps.
Anyone who wants any or all of these machines, including some free
apps to go with them, is welcome to come and rummage.

Ok, I give up. I've searched high, low, sober, etc., and cannot find one
single solitary instance of the file NDIS2SUP.386. It is supposedly on
Disk 7 of the WFWG install set. I have a set that has 8 disks but the
file is nowhere to be found on any of them. I've found references to the
file WG0971.EXE which should be a self-extracting file that contains
NDIS2SUP.386 but it cannot be found, not even where it should be on
Microsoft's FTP server.
I spent hours on Google and it is not there. Maybe someone else has more
Google foo than me, and you're welcome to try, but I'll bet someone out
there has this file. If so, PLEASE e-mail me directly to let me know.
Thanks a thousand times in advance and may all your dreams be naughty.

I finally decided to pick up the HP 9000/216 box which had been laying
around at my usual supplier for a few weeks. I spent a little time
looking at google, and can't find much info on them.
>From physical examination, it looks like it has a 1MB and a 256kB
expansion memory card (so 1.5MB total), and a fairly large keyboard,
which is different than the "standard" keyboard that comes with it (it
includes a dial at the top left, and has grey keys instead of brown).
I was wondering if these are actually somewhat rare, or if they're just
not very well sought-after. If anyone is interested in giving me some
$$ for one or has something interesting (mostly old DEC), feel free to
bother me about it.

Hi
The simplest method would be to use the cross coupled
nands as another described. For 8 inputs, you'll need
4 ea 7400's to make the nand latches. You'l need 8 ea 8 input
nands ( forget the 74 number ) and 3 of the hex inverters,
7404s.
For each switch wire one lead to ground. Wire one lead
to a 4.7K pullup resistor and one of the free inputs to the
cross coupled nand pair. Also wire that switch lead to
7 of the 8 input nands ( not the one on this switch circuit. ).
On the remaining free inputs to the cross coupled nands
pair, wire an inverters output. The input of the inverter
goes to the output of the 8 input nand that wasn't one of the
7 connected to this switch.
Repeat this for each of the 8 switches.
If the active level is to be 0 when selected, you can save
one inverter IC. If it needs to be active high, you need the
inverter. in either case, you need to connect to the nand
that has the inverter to the 8 input nand. This will ensure
that multiple switches won't select anything until only
one is selected.
On the 8 input nand, you'll notice that one input isn't
connected. This can be used to reset. Tie all together
with a 1K resistor to +5. Place a diode across this such
that the band is on the +5 ended.
Add a 10uf tantalum to this net with th plus on the
same net and the negative to ground.
This will reset all on powering up. If you want to
one of the outputs to come on when powering up,
you can add a similar capacitor, resistor and diode
circuit to the desired input switch lead. You'd need to
remove the common input to the 8 input nand and
tie it to +5 as well.
I like this better than using some other clocked method
because if multiple switches are selected at the same time,
non will select but when the last switch is still selected,
that output will go active.
There are no ambiguous states and no oscillations. The switches
are debounced as well.
