HI there,

I can't believe I just found a forum dedicated to those wonderful machines that are copiers... I'll tell you more more about my life and the pile of copiers I still have another day but for now I'm crossing my fingers to get an answer I've been looking for ages...

Can someone provide me with the DRAM PC Link cable pinout for the MGD2?
RJ11<->DB25 I believe

If you own the cable, I guess a few seconds and a multimeter should do the trick Laughing

Thanks in advance! Wink

i have a napkin schematic, i made a cable for some one back in the day.
i dont have the time to redraw it up but if you have the courage you can try to under stand my sloppy drawing/writings.
let me know and ill scan and post it.

Thanks a lot acem77 Very Happy

I guess 6 pins to connect should be quite easy to understand even on a napkin Laughing

If u don't mind scanning it or taking a snapshot with a camera, I would really appreciate. Wink

i hope this helps it does need one IC

to clear up the lines that are confusing

DB25(pin9)-->IC(pin11)
DB25(p5)----->IC(p19)
DB25(p11)--->IC(p9)

What a pity I missed your website when it was online, the only one I found is here:

The MGD2 is by far my favorite copier. Let me know if you happen to put it the site on again Cool

Are you sure the IC is a 74HCT44D? '44 doesn't make any sense. A 74XX440 on the other hand makes a whole lot of sense. Unfortunately the 74XX440 has been discontinued for a very long time, the only alternative available now is the 74LS442 which has tristate outputs instead of open collector. In addition to that, it costs $18.
