Built around the Intel 82310 Micro Channel chipset.
The board uses a rather unusual reference designator scheme for ICs. The
standard "U" prefix is followed by one or more letters indicating the column
(A-P, left to right) which is then followed by one or two digits denoting the
row (1-13, top to bottom). Additional letters are sometimes used for
in-between positions. But there are a few exceptions that break these rules.
P500 Planar P5 BA242 (1 MB), BA243 (2 MB)
A slightly different layout compared to the P4.1 planar above.
The right-most two SIMM sockets are Bank 0, the left-most two are Bank 1.

BIOS Revision Levels
ROM BIOS 1.06
Solves: Handling problems with IBM 3270 board
ROM BIOS 1.09
Solves: "Real Time Clock" random errors
For use with the user diskette Ver. 1.06 update 4
ROM BIOS 1.14
Solves:
- System crashes during initialization of the mouse drive if the network
password is enabled. The Keyboard controller can not accept the password
- Problem with the Intel chip set during access to the system board port
107h.
- Problem with the "Monitor detect routine" when the monitor is not
present
- Problem in hard disk initialization when an error is found in the
configuration of the HD controller even when configured correctly
- Problem in initialization of the IBM twin serial port board
- Incorrect video management
- System slow down caused by operation of Real Time Clock
- System crash when the parallel port functions are used under Microsoft OS/2
and the ABIOS interface
- ABIOS initialization problems
For use with the user diskette Ver. 1.07 update 2
ROM BIOS 1.16
Solves: Compatibility problems with standard VGA
For use with the user diskette Ver. 1.08 update 2
ROM BIOS 1.18
Solves:
- PS/2 mouse faults
- IBM 8514/A installation problems
- Parity error when BUS is loaded with different boards
- SW IBM 4700 problems in banking environment
Power Supply
Type PS13A, 140 W, manufactured by Hantarex.
Uses the same connector/plug as the Model
60/65/80 PSU. It's however unknown whether Olivetti duplicated IBM's
pinout.
