Astro Chase 10-20-83

Little is known about this version of Astrochase that surfaced on Ebay in 2022.  It is thought that this version may be in PAL format due to the screen rolling, but this has not yet been confirmed.  It is interesting to note that the label on this prototype is typed and has descriptions as to the function of the difficulty switches, whereas the 10/25 prototype has a handwritten label.
