Thank you Trevor !  This is exactly the sort of thing I had in mind.  Could
not find this in the Farnell catalogue, but that does not surprise me,
because Farnell's online catalogue really sucks :(  I will dig deeper into
the catalogue to try and find them.

If you have a part number(s) (?) that could possibly save me another
frustrating search through Farnell's brain-dead on-line search engine.

I am not sure if they are what you have in mind, but I personally have
been using these SMD IC prototyping PCBs that were obtained from either
RS or Farnell here in the UK, and I also got exactly the same PCBs from
Konrad in Germany when I was visiting there.

Basically it's a Eurocard sized board that has lots of SMD IC footprints
of varying sizes and pitches, with their pads leading out to circuilar
pads that you may solder your Kynar wire to. I have been using these a
lot at work lately. What I did was cut out the footprints I actually
needed from the board and fixed those cutouts down onto the topside of
my veroboard, like with the EPSON LCD driver chip here:

By the time I finished this board there were several other 80 and 100
pin SMD chips sitting on it as well, with pitches going down to 0.5 if I
remember right. It was quite easy to do this using the SMD prototyping
boards and chipping them into pieces.

Thankfully my project has moved onto the proper PCB stage now.
