This is actually the RC-M70JW model, one of the best boomboxes circa 1982-1983. AM, FM, four Shortwave bands, cassette with programmable music search, analog power meters, and lots of oomph!
This one is dirty and has some flakey controls and indicators, but it still works and sounds great, especially for the $5.00 I paid for it!
