Arguably off-topic but since Ashley Greenup has already been mentioned…
I used to have Ashley Greenup Power Box Simulator on PC. I lost the install disc and when I changed computers some years ago was therefore unable to use it any more.
I looked to buy another copy but was told it was not possible to use it any more. I think (it was some years ago) that someone suggested that it would run very fast on a more modern PC and be unplayable.
Can anyone confirm if whether that is true and, if not, have they direct experience of using it on an up-to-date PC? If it is usable, I’ll keep a look-out on ebay. (Then there will be the fun of trying to install from a 3.5” floppy on a PC that has never heard of them…)
