Well I am sure this will vary from site to site. I know that a lot
of institutions (this one among them) will provide "free" Internet
access to its reserchers, so I guess it would take a few years to
catch up to the price of a PC! But let me rapidly add (so to avoid
missunderstandings) Internet is not free, it cost, but some school
pay up and do not transfer the cost to its users. This may not

I am not sure about the limit of CLUSTALL (in PC/Gene or the PD
version) is, but I am sure it is beyond 24. I am sure somebody
will correct me if I am wrong :-)

It is very true that very few packages take advantage of the multi-
processing capacity of the 386 and 486, but with these higher-end
models you also get "faster" (the MHtz number) performance with
"cheap" 50 MHtz/486 on the market ... I assure you, you will
see a difference.
(action of opening a can of worms ...)
But without wanting to get into the ball going on this subject
(again!) maybe a low end workstation is an alternative to a PC
buyer. There is a lot of "front ends" for public domain (PD)
software out there, GDE for example. A wonderfull piece of
work which lets you use all sorts of PD software.

I don't know of any for OS/2, but maybe you could ask your Pharmacia sales rep about this one, as their ALF sequencer works under OS/2 ... they may know ... My Pharmacia Sales rep did not know of anything 6 months ago. They actually included (back then) the DOS DNA* with their package ...
As far as window 3.* there is the NCBI "entrez" and "Macaw" available from ncbi.nlm.nih.gov. Very nice packages.

OK, some of us do have to get back to work ... ;-)

I don't know of any for the PC, but would like to look at any you may find ...
