I have the original power cord. I used to have the original box, however unfortunately it rotted from moisture in the basement.It's a cool collector's item. Every time I stumble across something like this I compulsively buy it and then go home to screw with it, being the nerd that I am. However, unless you are the type of person that wires RJ-45s in your sleep, it will probably just collect dust.
From my research (literally just googled it) these are selling for $80-100 in the original box and with all the accessories (casset player, original 2 games, PSU, etc). If what is in the picture is all you have, it won't even turn on, considering these use an external power supply. As is, it's not worth anything as far as resale is concerned. If you have the accessories then that's a different story. HMU if you do have them
It has some serial port like connectors as well as some cartridges.Beside power supply you also need an audio cassette player to run programs/games off as it doesn't have any storage in it. It also has connector for game cartridges. There are still games for it and could be downloaded https://www.gamesdatabase.org/all_system_games-commodore_vic-20 but you have to record them to audio cassette tape thru sound output on a PC. It has to be mono though.
I probably will tinker with it for a bit; but thing is, I just don't see myself holding onto this forever.or start banging out some basic commands
10 print "hello!"
20 goto 10
i found this, dunno if you can get these in text form to type in. this kinda stuff is what would be in the back of computer mags before cover-disks.
i've got one myself, with cassette desk, carts etc. must dig it out to see if it still works...
You see, I do have the RAM expander.You might want to check the power supply voltages aswell. I dont know if this applies to vic20 but i think the c64s powersupplies would slowly fail and send more and more voltage killing conponents.
