Tony, re-read Steve's article. He modified the original CGA card so it would drive one of the CGA to VGA converter cards so he could use a VGA monitor. John :-#(#

Wow. Your a bit of a knob aren't you.
I guess this is why people tell me they don't share information because of tools like you.
This is freely shared information Tony if you don't want it close your eyes.

"The following are instructions on upgrading the video card from RGB\H\V (Inverted sync) to VGA standard"
1. I don't believe you are upgrading the video card to VGA standard. That would be quite the feat plus why would you need the external conversion board?
2. You don't explain what is the purpose of the various jumpers and cuts. If it is just to negate and combine the sync, since you already have an external enclosure housing the GBS8220 which is being fed 5vdc why not just use a 7400 to handle this and not hack your video card?

Hello list
I just spent the last couple of evening working on modifying my 9100ft to colour VGA after years of using the fluke black and white monitor.
I have documented how I have done it on my website here:
https://sites.google.com/a/boomspace.co.uk/poachersropeworkshop/test-equipme...
I have also documented how I replaced the SCSI hard drive with the SCSI2SD adapter.
Many thanks to Martin White and Andrew Welburn for their previous work and assistance.
Cheers
