Subject: Re: [korgpolyex] Poly 800 Super Mod Kit - getting closer

From: Michael Hawkins <korgpolyex800@...>

Hi AS,

You won't need the chip select chip - I'll supply two in the kit.

So you can pull out the chip select chip by snipping all of the legs off as you suggest.

But the EPROM socket is a whole different ball of fun (not) because it is one of those large types where you can't get to the pins to snip them off.

So to remove the EPROM socket requires a lot of patience and care.

I am going to try a few different methods on the three Poly's that I have and will be recommending the method that works out best. If I find the right set of cutters to chop the socket up while not damaging the board, then I may supply the cutter in the kit too.

Now that you point it out to me though, I better work out what the best solution for that may be because it is also plausible to leave the socket in place but it would mean using a really nasty set of header pins to plug into the existing socket. It would not be pretty at all.

Mike.

============ ========= ====

after removal, will those parts be needed? or will they be superseded by
new parts that will come with the kit?

after many years of electronic work, i can say that removing soldered DIP
chips without damaging the chips or the board SUCKS. of course, they're
easy to remove if they can be destroyed in the process... just cut all of
the legs off with a small electronic snips and then remove the legs from
the board, one at a time.
