Whilst looking for my copy of Tube Elite (not found, as yet) I cam across these discs and thought they may, or may not, be of interest to someone:
Discs 3, below: Alan would be Alan Glover. He did some work for Pineapple, for us (ACP/P.R.E.S.) and finally worked at Acorn. - He also did the RiscOS Protection Discs (if I could remember the title!)
If anyone is interested I can let you 'borrow' them, as long as you copy and Archive
