A programming software for D.Tait PIC16C54 programmer is here
It has been difficult to obtain 74HC299 chip for this
design. No I keep them in stock. See my pricelist (a finnish pic
price list). See additional documentation
from
Henry Palonen home page
Also BAR28 diode has been unknown to many people. Technical
data you find here
http://www.st.com/stonline/books/all/3287.htm in PDF-format or in html-format.
Suitable replacement is Schottky 1N5819 ( €1). I keep then in my stock.
I also program PIC16C54, if you are too lazy to build a programmer for
one time job. Send me
a hex-file.

Questions about TAIT Parallel PIC Programmer
Question #1
I build the Tait Parallel Programer with your design of PCB,
and i can't make it works!!. When type
pp54.exe then show me in the screen " Hardware not Found ". I use an
short cable (20cm), and a large cable (100cm), also config the setting
of the LPT1 in ECP, SPP, but no have a solution.
There is something i can't understand, the configuration
of the switch , i make a lot of bridges betwen the pins, and differents
combinations, surely this is my error. I thank you any information you
can send me.
Greetings from Argentina, P.Adrian

Answer #1
Ask help from local electronics people or radioamateurs.
The remote debugging is not easy
SPP = Stardard Parallell Port is enough for this design .
Try these first
- measure power supply for each IC, 5V and also 0V against 5V
supply
- use debug.to test that LPT wires go to right ICs
DOS Debug program is located in c:\windows\command\debug.exe
WIN9x
I = input command e.g. I 37A
O = output , 378 LPT address in HEX , FF all pins on
IN DOS box write
debug.exe
-
O 378 FF ( set all LPT pins on on LPT1)
O 378 00 ( set all LPT pins off on LPT1)
O 378 1 ( set pin 2 on, others
off on LPT1)
Measure pins level in the board according your test.
If this do not help read parallel port information from internet or
buy a book: Parallel Book Compleate, Jan Axelsson

... email goes to Argentina... still waiting...now the answer is coming...
Thanks a lot for your help!!!
The programer is now working perfectly. The problem was a error in the
construccion of PCB where the pin 1 of the DB25 are inverted to the pin
13.Can you believe it!!!
An another mistake i make was replace the R6 show in the Schematics i have
(12R) for 12K, using this value i can read, but i can't write, when use
12ohm works perfectly.
Thank
for your time!! Saludos!! Adrian Pulido <pladryan@ecolan.com>
