60/65/80 
CPU- 486DX2/66, 486DX4/100, 586/100 
CPU Socket automatic voltage detection and switching. 

Memory 
   Max on board 64MB 
   4, 8, 16 or 32MB, 70nS parity SIMM Sockets  Four 
   optional L2 cache 128K write-through (supports 256K!)

   I am running 4x 8MB 70nS (32MB) right now, but when I grab some 16MB simms, I'll pop it up to 64MB. 71G0438 Synchrostream!

  I ran a POD and L2 256K WB, but I got some lockups under OS/2 (that's ODD) so I pulled the L2 until a future install.

Video
  OS/2 identified the chipset correctly AND offers some hi-res modes, especially when you pump it up to 2MB with the addition of two 256kx16 SOJs (cheap things, maybe $2.50 each). I set it up on my 17" Eizo for 800x600x64k at 72 Hz. I love it. Finally, decent video...

Video Memory- 1MB DRAM standard, colors with optional 2MB 
Resolution    Colors   Depth
    640x480    16M    24 bits/pixel 
    800x600    64K    16 bits/pixel 
  1,024x768    256     8 bits/pixel 
1,280x1,024     16     4 bits/pixel 

   The Reply setup program is different. I am still figuring how to LLF SCSI drives. Also, setup takes a while to identify and configure SCSI devices, to include SCSI adapters. I got an IBM SCSI w/cache lit up finally. Ran the IBM diagnostics on it. So I think I can just copy the *.dgs files and try again.

Floppy
   Controller supports 1.44 and 2.88MB floppy drives.  Presently running a 2.88MB floppy from a 95.

Failure to Copy ADF, or Damaged ADFs
   I tried to install a FW and a FWSR on my Powerboard, but I got errors where the setup program claimed the adf on the options disk was damaged or that the adf was not found.
  I took out the 83MHz POD and used a 486DX4-100 to successfully install a BusLogic BT-646S that had failed before. Also, I had to edit the @0709 adf because the Reply setup called it @0708 (BT-640).
   My SWAG- either a timing or compatibility problem (without interposer) exists. After copying an options disk, you must reinstall the POD.

Ports
