The Sigma uv1700 uses PLCC chips instead of EPROMs for the
roms at U51 and U52. If you own a Sigma 1700, at some point
you will probably need to burn a PLCC. The PLCC does not look
like an EPROM, but essentially they are a 4meg EPROM.

The blanks (PLCC 27c040 or 27c4001, 32 pin) can be bought from
Mouser.com just search on "PLCC 27c040", part number 511-M27C4001-10C.
Cost is about $3 each.

In order to burn the PLCC, you need a PLCC adaptor. With this
PLCC-to-32pinDIP tool, a regular EPROM programmer can burn
the PLCC. No special software is needed. (I'm using an old
Needham PB-10 programmer without any problems).
You can buy the adaptor for about $25 on ebay. Here's the one i got:

Cheaper versions are available, but this particular one has an
easy in/easy out PLCC socket, so that's why i spent a little more
money than the $10 elcheapo variants.
