It's a Sanyo/Otto SANYO OTTO TAP-M5 RD-M5 SX-M3 Junk Negotiable (System Component)|Auction information and yahoo product information archive released - Oakfan (aucfan.com)
I wasn't even thinking about it being an all-in-one, it isn't bad looking and looks like it might be nicer than the Sanyo BPC we used to see.
From 1976, this is interesting, most of the mono boomers back then look very similar. Anybody know what model this is? Singapore is where the real clone wars was happening, I wonder if George Lucas got that terminology from here? The Straits Times (Singapore).
