Historical inaccuracy ...
"with an amazing 128K RAM, 8086 16 bit processor and twin 2.4Mb 5.25-inch variable speed floppy disk drives".
... would place it in the early 1980s. Except, the size of those floppies has surely been overstated? My recollection is that the later 3.5" discs were, at 800kb (or 720k formatted for msdos), quite a lot bigger than the 5.25-inch ones had been.
