It's interesting that the games are complete in their boxes. A lot of people got rid of the boxes. I haven't seen any old computers on Antiques Roadshow.
These disks will be nearly 30 years old so it will be important to verify that they still work. If disks are kept in a cold or damp environment they may have deteriorated. If you list all the games I'm sure people will comment on their rarity. You can guess their value by checking completed listings on eBay.
Still got, still working: Atari 4Mb STe, 520STFM, 2.5Mb STF.
Hardware: Cumana CSA 354, Ultimate Ripper, Blitz Turbo, Synchro Express II (US and UK Versions).
