PC2JAMMA project - PRINTER HARDWARE - RELAY VERSION
Hi John, ( and everyone else also…. )
To build the printer hardware just order the IC's listed on the PC 2 JAMMA project page, and I choosed the CMOS ICversion. I think they are called 74 HC XX instead…
And for the transistor, the one that Brian have listed has been replaced by another transitor ( they work the same way )
NOTE: ( in the PC2JAMMA HTML text there is an minor error ?… )
'Strobe' (pin 1)
'Data bit 7' (pin 9)
'Acknowledge' (pin 12)
'Busy' (pin 11) (Should be PIN 10)
'Ground' (pin 25)
When I checked the pin config in my manual I saw that the 'Acknowledge' should be PIN 10 and if you look close on the picture, you can see that brian have pin 10 there.
And for the relay, I chosed a 120-250V, 5 AMP realy, you can more or less chose what ever you want.
But I think a 120v-250V, 5-10AMP, 12V should do it…
And when you have built everything, test it with the software that Brian has on his page " MONTEST "
" DO NOT CONNECT THE 120/240V when you test it , JUST IN CASE "
TAKE YOUR TIME AND YOU WILL MANAGE TO BUILD IT.
Soon as I get my hands on a digitalcamera I will take some photos….
