I bought a HeNe laser a while back from someone who I don't have even a name for
which is too bad.  He had many of them and I bought it for $50.  Does anyone
remember this?  Anyway I have need for several (arbitrarily large number) more
but they have to be in that same price range for me to afford them.  Can anyone
offer me something like this?

I know someone who is selling 1MB*9*80ms SIMMS for anyone who is interested.
I will give you his address and you can talk directly to him.  I get nothing
from these referrals.  The cost per SIMM is $35/MB  He may have posted to 
misc.forsale.

Exactly what differences make the line between Unix and a real-time Unix?
I don't think I understand the concept.  A real-time Unix is supposed to
run in real-time regardless of the load?

I would like to tell you about my robot.  I am taking a 6270 board and a whole
string of miniboards and making a SPI network for them.  I hope to use the
6270 for (along with other uses) file serving (read: downloading new programs
to the miniboards.  I hope to get a multi processor based robot out of this.
I know that there are easier ways (probably) to do this but I thought it would
be really cool.

I am starting a robotics club at my university.  I hope to get some Students'
Union funding to pay our way to the various competitions.  Can someone please
post or mail me a list of ALL upcoming competitions and contact names.  I have
the info on the one in San Francisco but there must be others.

I have a (my own personal) IBM 4331 mainframe, associated disk drives, tape
drives, etc and about one hundred terminals.   Anyone have any use for them?
Mail me for info.  Now you ask:  Why does he have something big enough to
fill a room in his basement?  Well I was going to start a public access Inet
site (can you believe a city this big doesn't have one?) only the UofA has
a connection and only for staff and students.  But it looks like I can't come
up with the $40K/yr that ARC wants for a connection.  

I am wondering:  If I build a robot with a huge appetite for electricity...
say multi amps continuous current.  How could I feed this thing without a
wire.  I could maybe transmit the pwoer with a Telsa coil... Is there an
easier way?  Just wondering.  Oh. Yeah  This may need to be indoors so I was 
thinking that a combustion engine may not be the best solution.  Any comments?
