I've still got the Duo 230 w/the following items:
Working external floppy drive (sorry, no floppy adapater)
Working Duo Dock (1) (replaced floppy drive)
Working Duo 230 in great condition. Next to the bad screen plastic where the screws go through that hold the front to the back. I trimmed them down with a dremmel, so it looks fine now. Ask for a pic if you need one. The original 80MB HD does not work, but I will include it. Has built in 14.4 Apple Express modem (should work) and 18MB RAM with the 16MB(?) RAM modual. All keys work, trackball works, screen works too.
Working Duo 280c power adapter.
Working 2 conductor phone cord
One good type 1 Apple battery. Is not gurrenteed though. Held a 45 minute charge last time I used it. Only seems to work when a system is booted off the HD though.
One bad type 1 Apple battery with battery case, and one bad BTI type 4 battery.
As-Is Duo 210-231 interconnect board.
Working Duo 12MB upgrade modual.
As-Is Apple Express 14.4 modem card. Turns the computer on fine, but not sure it it'll connect or anything.
One good power cord. (black)
Replacment Duo 210-230 speaker, brightnes/contrast button assembly, display to mobo cable, and interconnect board to inverter board cable. All in good working condition.
All of this was cleaned/inspected/tested by me personaly. I do not warrenty any of this. But I will put insurrence on it if you like. I'm selling it for $50 or trade for a good working Sega GameGear with three games, and power adapter. Shipping is $20. If its more, I'll pay for it :).
Thanks,
D.I.
P.S. if you need a certain part from the Duo or something from the list, I'd be glad to trade for GameBoy stuff. Don't need a light, so please don't offer one :).
