Thanks all for your help - thought I'd post an update on how it went.
I couldn't "downgrade" to System 6 with the System (7) Folder already present (renamed to System Folder 7). The System 6.08 Installer disk would keep choosing it and wanted to overwrite files. So I moved the folder, installed System 6.08, then dragged back the System 7 folder - System Picker now dual boots the two nicely.
The "Desktop Manager" INIT as unusually found on the AppleShare Admin image definately does work, neither OS complains about having to rebuild the desktop switching between the two. One quirk is that somehow Multifinder is enabled by default when you switch over to System 6.08, which I tend to never use and most games don't like it.
My only issue is that the SE seems a bit crash prone - not many older games work, and I'm sure they were fine when we had a Mac Plus with 6.08 - I appreciate there may be some slight incompatibilities but it does crash at strange times. The caps are original - sound etc is all good, PSU fine, RAM seems fine - does replacing the caps improve stability of the machine?
Thanks
JB
