I can't believe it's been so long since you wrote to me.  I
apologize for not getting back with you sooner.  It looks
like I'll just need 2 of the H851s for the M8300 and M8310
cards.  The other thing I especially need is an M8320
Bus Load Card.

Beyond those, I've got a line on an M8650 async card,
but I'm thinking I may want two before it's over with.  So
if you've got one for a good price I might be interested
in it too.  At the moment at least, I'm planning to either
get one of Vince's memory cards or to build something

 Hi Brian,

 Can you call me some afternoon or night this week? 
 till 11PM Chicago time
 is fine.
 Thanks, Paul
