I think i posted this correctly now. Hey guys, noob here who would like some info on a keyboard i've had laying around for 20 years. It's a Casio DM-100 i purchased Feb 6, 1990...i found the receipt in the box. Anyways, i'm looking to sell this thing because i don't play keyboards and maybe fooled around with this thing for a couple of days after i purchased it. Any info ie. testing for full function, value, ect, is apreciated. It's in its original box with the manual, receipt, invoice and ac adapter. I can upload some pics if necessary, thanks.
