I always wanted this one but never found one, kind of basic now but as a school kid, it looked like the answer to boring classes.
Cool cool cool, I too wish I had one back in the day. Still we can but $250? https://www.ebay.com/itm/Casio-BG-1...818919?hash=item261fa75ba7:g:cQUAAOSwd2JdCAoG
It's new in box, if you talk to Longman, it's most likely holding it's value. All of these games were so neat, even if they were kind of primative, there was nothing else out there. I still have my musical Casio and found another exact version, they were so neat and to be able to play notes on a calculator was cutting edge back then. There are very few innovations in hardware these days, it's all software and that's about as exciting as warm beer.
I had one of these when I was a kid but it was stolen from my school bag. Bought another on eBay last year for about £20, still fun to play now and then!
