A fine piece of retro goodness. Great condition too, I hope it works for you. Nice find.
There's a little bit of info about it here: Miscellaneous | Vintage Electronics Have Soul – The Pocket Calculator Show (http://pocketcalculatorshow.com/walkman/etc/)
(Pretty far down the page, search for PS-01)

Wow, it looks really sexy in its leather case! Must unearth it... really slim, great build quality, internal lithium battery and an external power pack... had kept me so much company walking to and from the university! *sigh*
Also: great page, Bryce!
Yeah, The Pocket Calculator Show is a mine of information, with great pics and a seriously Retro header too :)
I had a JVC back then, silver plastic with record and internal mic, but I can't remember the model name.

Yeah, the banner is simply beautiful; reminds me of a recent Sony mobile phone commercial (as a commercial I think it was a bad idea, but the shot of the ladies skating while listening to their walkmen is beautiful)
