DCE Scanmagic

Scandoubler only


Hi guys i have had this from dougal here

https://www.amibay.com/showthread.php?p=285518#post285518

when i first connected it wouldnt give a display so i looked at the rgb/vga pcb and noticed that the sockets were loose.

so with my inquisitive brain i decided to resolder the socket but noticed that there was a very thick gooey stuff holding the protective cover on


so i used a little screwdriver to lever the coveroff and it broke into a few pieces

the stuff holding it together is like bluetack but stronger

so after an hour using my hot air/soldering kit, a screwdriver, a touthbrush, and my burnt fingers i managed to get it off

but as you see in the pic thats not all i took off



tracks and pads too








i took photos of the board and used a photo program and pinout diagrams to fathom what was connected to where




Amiga 23pin port looking from the back with socket plugged in

15 pin vga socket

after a few pms to hikey about it thanks mate i figured it out

and wired up a vga socket and a 23pin rgb socket (temporary)will use a PLCC Socket 84 Way 2.54mm PCB Pins DIP coming from ebay to make fully internal

so here are some piccys











complete for now


and here we are yay working

with some banding


i will update with some wiring pinouts and diagrams when i have cleaned them up for anyone else wanting to try it

thanks for looking

Wow!! You have really been working on my ex scandoubler .. Keep up the good work

 

[rkauer]

Excellent job, here! You sir will receive a seal of approval!

With reference to the banding, it does seem to depend on your monitor just how bad the banding is, my syncmaster has a "coarse" option and it does make a difference.

I hope the pictures show what I mean?

cheers justin will check other monitors when i add the 84pin socket

i think he could work out the pinouts from that john

EDIT: looks like its using the 23 pin port at the amiga for h/sync v/sync and ground
