Was bored today and was fed up looking for a 13W3 adapter so pulled out the iron and a few things around the shop.

Means I can only use one GIO slot but oh well, it's not like I don't have three more of the damn systems. :roll:

Very cool Pentium! I have seen couple of Wiki postings on this, but not based on the numbered pins on the Indy's mainboard. If you don't mind, could you please post the wiring diagram you used to get this to work?

Five years later I want to point out that I really badly screwed up the 13W3 pinout and never saw sgifanatic's suggestion to fix that. :oops:
The one several posts above applies to other machines like the Onyx or Octane which use almost none of the extra pins on the 13W3 connector. Indy Newport Graphics however are a lot more monitor friendly and also supply a horizontal and vertical sync. The pinout is listed on page 201 of the Indy Owners guide but here's the proper wiring chart.

Code: Select all

13W3                                         VGA
1 (Monitor Type 3) ------------------------- 15 (ID Bit 3)
2 (Monitor Type 0) ------------------------- 11 (ID Bit 0)
3 (Composite Sync) ------------------------- N/C
4 (Horiz. Sync) ---------------------------- 13 (Horiz. Sync)
5 (Vert. Sync) ----------------------------- 14 (Vert. Sync)
6 (Monitor Type 1) ------------------------- 12 (ID Bit 1)
7 (Monitor Type 2 -------------------------- 4 (ID Bit 2)
8 (Ground) --------------------------------- 6 (Red Shield)
9 (Ground)---------------------------------- 7 (Green Shield)
10 (Ground) -------------------------------- 8 (Blue Shield)
A1 (Red) ----------------------------------- 1 (Red)
A2 (Green) --------------------------------- 2 (Green)
A3 (Blue) ---------------------------------- 3 (Blue)
9 (Ground)* -------------------------------- 5 (Ground)
N/C ---------------------------------------- 9 (KEY/DDC +5v)

*All grounds are common, so it doesn't matter if you use pin 8, 9 or 10.

I changed the wiki to reflect this. Let me know if it needs more work.
