Made more tests and discovered that the safest ROMs to use are eventually the ones on the ATW800/2.
When I use the Monsterbo ROMs or motherboard ROMs (fitted on the Ghost adapter), everything works fine when the Alt-ram is disabled,
With Alt-ram on, I have various issues arising.
Can all registered uses please login, even just for a few minutes..
It helps build a picture where our "good traffic" is coming from..
Thanks :)

@rubber_jonnie
Hmm, quite tempting question...
I'm just afraid that if I install TRAMs there will be issues with the Alt-ram.
Maybe @Steve has the answer ?
Would you post a picture of your TRAMs ?
Thanks.

@HigashiJun you won't get any additional alt ram problems with the TRAMS, they run in their own little world outside of the Atari address space.

Re: ATW800/2 in a MonSTErbo powered STE
@HigashiJun These are the TRAMs @Steve kindly supplied me:
And here they are installed on the ATW800/2:
I would add that there seem to be various different TRAM boards out there so the 'installed' image should not be considered a de-facto install, you should check how the modules you have install.
There should be a marker/arrow on the corner that lines up with a similar marking on the ATW sockets. They install in opposite ways.

Re: ATW800/2 in a MonSTErbo powered STE
@Steve, thank you for your confirmation.
@rubber_jonnie Your TRAMs look good !
If I manage to get my hands on a couple of reasonably priced TRAMs, I guess I will take the plunge.
