Hi Siegfried,

I hope I'm not missing the point on your 16Cxx in-circuit
programming question, but why would you need to program anything
but an 84 in-circuit?

Please sit me back in my corner if I am way off the mark.   :-))

1)  An EEPROM chip: Fine. Load and go!
2)  An OTP chip: No, why?
3)  An EPROM chip: Yes, but needs eraser placed over chip and
    takes a little time, however as any socket can easily be
    converted to a temporary ZIF socket, a standard programmer
    and several EEPROM version chips may do the same thing more
    readily.

I have a Parallel Port driven Serial In-circuit Programmer that I
would like to see your comments on. It uses the bull-dozer
approach to Load and Go programming. A Program/Run 4PDT switch is
used to control this feature.

It is based on David Tait's design and uses a 10 pin IDC header
and flat ribbon cable to get to the target board. This header is
pin compatible with a design featured by Dr Russ Reiss in Circuit
Cellar magazine.

It also has provision for an on-board 18 pin ZIF socket and a
power supply capable of running both the programmer and a small
target system if required.

A suitable prototype target board (PIGMY) is also available that
has the matching 10 pin header on board and has support for all
18 and 28 pin PICs. It has support circuitry for the Parallax
Basic Interpreter (BS-1) chipset, plus DB-25, MAX-232, etc., etc.
