Here is the sad story which I got from IBM technical people.  The model
50-201 (check your back panel for model number) is 1 meg on the mother
board and cannot be upgraded.  It has two 512K simms (two sided with
256K x 1 chips).  All the other models of machine can handle more memory
on the motherboard - even the model 30-286!  So to upgrade the memory
in your model 50-201 you must buy a memory card.  I think the address
space is 16 meg.  I talked to a guy selling memory products who said he
could sell me a Micro Channel card with 2 megs of standard simms (not
IBM proprietary) expandable to 8 meg for $420.  If this computer is
used for business you might want to consider trading it in for a model
30-286.  This is the same basic system in a smaller case and it'll take
4 meg on the motherboard.  Model 50s are selling for just under $1000
so you can get maybe 25-30% of the purchase price of your new computer
which will have a bigger hard drive.  UPgrading your model 50 disk will
cost you at least $600 for 30-40 meg.  Might be time to take the $1800
under discussion here and put it into another machine.

How do I know so much about this sad state of affairs?  25% of our PCs
are model 50-201s.  Would I like to give the design team on this model
some 'user feedback'?  No jury of my technical peers would convict me!!

And then I'd like to talk to the IBM keyboard design team.....
