things with epic :?
dont use ecp mode on your port
instead set it in the bios for normal mode
for programmers
as above you need too change the timing slightly
try too add more again for erase
remember it wont program properly if it dosnt get a good crc for erase
use the latest epic software
{i use icprog it always works }
attached is the design
i had to rework it as i couldnt find the previous .dsn
but no matter here you go
just needs routed
{very easy is almost at export level}
3 sheets so use design menu to navigate
enjoy
ps in this version
i did away with the shift register as it isnt realy needed
this design uses just one cable and will program with any software that supports the epic or propic
as i re worked it i havent tested but i am sure an eagle eye can scan and report a flaw too me by pm
i can then update it
i cant be bothered to route it
i will if me want this done {takes a couple of hours too set up}
but it is finished quickly so no realy problem too do
esp with proteus ares
other things too note
use 1 amp regulators
use 25v electro for the main resoviour cap
use 16 v for the rest of the electros
anything else
pm me for details or for other
faults i notice
OK A FEW BUGS FIXED LOOKS MUCH BETTER VERSION NOW
REDOWNLOAD IT
added some dsn files for placement and routing
you need some libs from vsm.libs site
devares devisis libs are needed
this guy does nice parts for proteus and has some nice links
and bits of interest
