Hyperport 2 [scan from "Lord" Basil Holloway]

   Appears to be a multiple serial port. 

U7 is an osc
U18-20 are National Semiconuctor NS16C450N
P1 is a 44 pin port.

   Does this thing use a breakout box or octopus cable?

Serial Port 1 Address
  This option allows SERIAL PORT 1 base address to be selected. If the HYPERPORT is not equipped with any serial ports, you must select 'OFF'.
   <"02F8" [02f8-02ff]>, 3220 [3220-3227], 3228 [3228-322f], 4220 [4220-4227], 4228 [4228-422f], 5220 [5220-5227],  03F8 [03f8-03ff], OFF

Serial Port 1 Interrupt Level
 The interrupt levels for serial ports depend on the software being used. You should consult the appropriate software manuals to determine what interrupt level is needed. If interrupts are not
used, or your HYPERPORT is not equipped with this serial port, or this port is 'OFF', then this option may be ignored.
   <"Interrupt Level 9">, 3, 4, 5

Serial Port 2 Address
" This option allows SERIAL PORT 2 base address to be selected. If the HYPERPORT is equipped with no serial ports or only one serial port, then you should select 'OFF'."
   <"3220" [3220-3227]>, 3228" [3228-322f], 4220 [4220-4227], 4228 [4228-422f], 5220 [5220-5227],  02F8 [02f8-02ff], 03F8 [03f8-03ff], OFF

Serial Port 2 Interrupt Level
" The interrupt levels for serial ports depend on the software being used. You should consult the appropriate software manuals to determine what interrupt level is needed. If interrupts are not
used, or your HYPERPORT is not equipped with this serial port, or this port is 'OFF', then this option may be ignored.
   <"Interrupt Level 9">, 3, 4, 5

Serial Port 3 Address
This option allows SERIAL PORT 3 base address to be selected. If the HYPERPORT is equipped with fewer than 3 serial ports, then you should select 'OFF'.
   <"3228" [3228-322f]>, 4220 [4220-4227], 4228 [4228-422f], 5220 [5220-5227], 3220 [3220-3227], 02F8 [02f8-02ff], 03F8 [03f8-03ff], OFF

Serial Port 3 Interrupt Level
  The interrupt levels for serial ports depend on the software being used. You should consult the appropriate software manuals to determine what interrupt level is needed. If interrupts are not used, or your HYPERPORT is not equipped with this serial port, or this port is 'OFF', then this option may be ignored.
   <"Interrupt Level 9">, 3, 4, 5

Parallel Port Address
This option allows the PARALLEL PORT base address to be selected. 
   NOTE: If the HYPERPORT is not equipped with a parallel port, you should select 'OFF'.
     <"3BC"  [3BCh-3BE]>,  378 [378h-37A], 278 [278h-27A], OFF

Parallel Port Interrupt Level
The interrupt level for the parallel port depends on the software being used. You should consult the appropriate software manuals to determine what interrupt level is needed. If interrupts are not used, or your HYPERPORT is not equipped with the parallel port, or this port is 'OFF', then this option may be ignored.
   <"Interrupt Level 7">, 5

Parallel Port Mode
   The parallel port may be used in either the 'COMPATIBLE' mode for output only operation, or in the 'EXTENDED' mode for bidirectional operation. If the port is to be used for a printer, use 'COMPATIBLE'."
