A66JLH92X03 - A means A-grade and the "66" is screen size (centimetres) measured corner-corner. Great size for arcade cab. The rest of it is manufacturer gobbledegook or at least stuff you don't need to worry about.
The "9509" is likely the manufacturing date: September 1995. It is fairly early for a bonded yoke CRT.
That only relates to the tube - the SI chassis was made much later by another company.

Smoking just dropped off from places when I was out and about. How times have changed and lot less smelly these days. 1981 is when I got my Atari 2600, total game changer as a kid!
Must say, your knowledge on this subject is outstanding.
So, couldnt help myself and gave the cabinet a tweak, so yep, changing the vhold certainly stopped the scrolling, but the screen is garbled and somewhat duplicated between the top and bottom half
Im starting to think I need some specific res to make it clear. Ill do some more reading and try and isolate this out.
So either I have to figure out exactly what res this needs and manually set this in GA or pop on Windows and set it there with some tools.

I don't know much about GA, but trust that it can get you to a basic boot screen at 15khz with compatible hardware. You get half a screen, which is encouraging, but half is missing. Your monitor seems good. So, unless there is some GA/GPU/hardware issue I don't know about, I'd guess something is wonky with your video connection between PC and monitor. Photos!
Would be good to know how they had it working originally.

Hi SCT74,
You mentioned you have an Nvidia card in that PC. Unfortunately support for interlaced modes is missing on the the Nvidia open source driver, at least for most of its hardware. That split screen should be a proper interlaced mode. You can however try using progressive modes only. On GA's boot installation menu there's an option called "EDID progressive". Alternatively you can force a progressive mode on boot, like 320x240.

Thanks for the info
I had a gut feeling it was down to the onboard video + GM Found a tool online that does a full hardware inventory on boot, so its a NVIDIA GeForce 6100 nForce 430.
I powered up the system as I had it and it has the Gamex frontend running on WinXP
I did try and mess around the EDID but didnt have any luck with it.
So i'm back to the drawing board at this stage, I guess my options are to get another card that is compatible or jump back to Win7. Im not sure groovymame will work with this card but will read more
I still have to figure out how the old system is automatically switching the res
Soft15khz and quickres are installed .. just need to pull apart the config properly and do more reading
This can turn into a rabbit hole at times .. trying to get everything to everyone in one cabinet is not feasable, so I have to readjust my expectations, which are now
- An update, make sure everything is updated, grab Win7 and give it a cleanup
- tidy up all the internals as they are everywhere
- rewire the controls with iPAC
- add two big buttons on the front for coin or whatever, just to cover the holes
- obtain more knowledge on what to expect out of the monitor resolution wise
- change the marquee and speakers
- Investigate a sexy frontend for it, whether stick with gamex, retroarch or something else
At the end of the day, its really just for the oldschool kinda games, streetfighter, mortal kombat, sunset riders, cabal, all that old goodie stuff
I appreciate the comments, sometimes I feel a bit thick with this but every nugget of information definately helps
