be careful about the pc-2 and printing. You can always make or refill your own 
pens.... but the MAJOR problem is a plastic cog within the printing mechanism 
itself. Over time these things would crack and then you would have abnormal 
printing operations. A brass or 3d printed version of that cog would revitalize 
98% of those ancient pc-2 printers. (that, and changing the ni-cad batteries 
with ni-mh ones).

You can still purchase PC-2 printer pens?  Excellent.  Where?

My PC-4 was my constant companion through college and into my first
job.  I picked up a PC-2 at the Tandy Corporate auction and got bit by
the pocket computer bug.

What I've put together is this:
+ PC-1 - usually had bad screens over time.
+ PC-2 - frequently people left the AA batteries in them when they
stopped using them.  The batteries leaked.  So always check the
battery compartment before buying one.  Leaky batteries can cause a
great deal of damage.
The printer/cassette interface is where the flaws are.  The printer
gears tended to wear out.  Also the rechargeable battery packs are
shot by now and are leaking.
There are some people who refurbish the printers (new batteries and
new gears), but they will be more expensive.  Surprisingly, you can
still purchase the pens.
+ PC-3 - Not much that I know of.  I only have 1 in my collection and
it has no problems.  The printer even works.
+ PC-4 - No problems with the pocket computer itself that I know of.
The printer batteries are shot by now.  Usually they don't leak, but
the batteries are not meant to be replaced. But with some work, the
printers can be made to work with an AC-adapter.

Some people like to work on old cars.  But old computers are cheaper
and don't require a big garage.
