      Kyle that is fantastic! Thank you so much for looking! I have lots I would consider trading: Peripheral Vision Dual 8 inch floppy drive cabinet with one 8 inch drive, Peripheral Vision PV1001 S-100 disc control board, no docs, has two sets of top edge contacts for connecting drives. MITS 88-VI RTC Bare Board, unpopulated, with a few components. S-100 Wire Wrap Board with 31 wire wrap sockets, partially wired. Large populated NON-S-100 wire wrap board, designed to interface microcomputer to IBM system controller as a terminal via high-speed coax cable. With 8X305 processor. 8X305 ICEPack with board for Intel MDS-80 system, software and original manuals. MITS 4K RAM Board 88-4MCD (Rev 2) with original manual. Cromemco Cyclops Camera controller 88-CCC Boards 1 and 2. (Rev 1) No camera.

      But since I'm a hoarder, I prefer to trade cash :-). You've got me drooling...please make me an offer LOL

The eBay seller misrepresented the item so it can be returned, but it is in such good shape I'd like to replace the transformer with a US version. In the meantime I'll try a 110-230V step-up transformer. There is a 50-60 Hz switch so that should be no problem.
      > The original 110V transformer part number is 129458-3. It has 3 windings: 9.4V used for +5, 31V used for +/-12 and 20.5V used for +15. I can't find any current ratings.
