My (Larry's) PET Page had switched servers back in Feb(?) you can now find it
(and a bunch of other new PET stuff) at:

Could be a pin I suppose,  I don't know the scan of the keyboard but it is
affecting much of a column (which is a giveaway, either columns or patterns of
keys not working, like every other or third...).  Though it could just be that
the keys need cleaning.

You have the connector connected properly, in the right port and right side
up?  Sounds almost like you are plugging the drive in the user port...

I remember those, bulky monsters (with that tractor thing sticking out),
though it was cool to have the PET trapezoid banner on the front.)  Could be
out of paper?  I recall the one we had at school doing that, look for a switch
that senses presence of paper and check it.

There are some games, some educational programs, a few word processors, a
database or three, VisiCalc spreadsheet, etc.

That was one of the later models; probably 1981 or maybe a little later.

In the U.S. it is quite rare, I think in europe it is more common (I am led to
believe that model was produced on that side of the Atlantic.

It was primarily a business or school machine, back then they were about
$700-$1,000 U.S., not cheap.

The BASIC is almost identical to the Commodore 64, with the extra 4.0 disk
commands, Check my URL (below) I have a good command quick reference and an
almost complete full reference...

I have d64 images on my site of some games, as well as some on the
FTP site too.  The tough part will be getting them to 8050 format as there is
no equivalent drive for the 64 (which would have been your best conversion route.

Really cool case, hope I find one someday...  ;)
