Now I have lost you completely. from your first post:

  Does anyone has an idea why FPP cannot erase and reprogram the 628A as
  it does so well with the 628 part ?

Bullocks. When DT wrote the software the 628A programming specs were not
available (if they were he would have taken them into account and listed
the 628A as supported). So if the software works with the 682A that is a
coincidence. But you stated yourself that it does not work.

IMHO 'the' solution is to write software according to the specs
(occasionally taking some piclist wisdom into account, for erasing a
c84-style PIC). I can not reasonably comment on using closed-source
outside its intended use. I could only point you (as others did too) to
the programming specifications, so you could see for yourself that the
628 and the 682A are very different in this respect. Feel free to
disbelieve.

Because the manual contains the specifications, and there is no
programmer software source to read.

I don't recall anyone saying that, but it might be a good idea anyway :)

And if you are doing that, do read the various threads about Olin's
response style and why (IMHO) some people deserve such replies.

> or "Buy a real controller" type of answer

You mean 'buy a real programmer'? That would be a good idea, or at least
one for which the software claims support for the PICs you want to use,
or failing that one for which open-source software is available so you
can DIY.

> when there is an intelligent solution at hand?

You mean try all combinations of settings untill you succeed? That is
the kind of thing you can do for yourself, I don't have the programmer
hardware you are using and if I did I would not want to experiment with
all the software variantions that exist for such programmers. I do have
a family to feed.

> When this sooo useful and dirt cheap setup of mine comes to

My programmer costs some $35 assembled, less in kit form. If you divide
all time you spend with your programmer (including building), and divide
that by $35 (minus hardware costs of your programmer), what is your
resulting 'hourly rate'?

NB this is not a mock question, I always state that using a very simple
DIY programmer is OK when you value your time at a low rate, but I have
no actual figure for that rate.
