HI everyone -
For those of you who put a 13-pin DIN Atari ST monitor port in your 8-bits with VBXE, how did you connect the pins?
I took Ground and R/G/B from J4 on the VBXE 2 board and connected them to their equivalent on the Atari ST monitor port.
I took CSync from my XE motherboard and connected it to three pins on the Atari ST monitor port: Composite sync, Horizontal Sync, and Vertical Sync.
This worked - but with two problems. I had to adjust the v hold on my Atari SC1224 to get it to work; and I never did get solid vertical hold. Each time I power-cycled the XE the screen image would come up in a new vertical offset, sometimes 1+ inch from where it was before.
Second problem is I had no RED pixels on the monitor, but this may actually be a problem in my monitor. I hope to try a different monitor Monday to verify.
I'm thinking about making a small board to make the Atari ST monitor port installation in an XE/XL/XEGS much cleaner.
It would have the 13-pin DIN connector on one side:
and a 2x7 or 2x8 IDC right-angle header on the other side, similar to this but with more pins:
it would also have a jumper to connect the various sync signals together, and anything else that can be done to make the install easier and cleaner.
I need to look closely at at my XE, XL, and XEGS but I think I can also make the board provide a better mounting solution than hot glue/epoxy for all three.
I plan to make this to just to keep my install clean - would anyone else be interested in one if I make it?
