****************************************************************************
|
||||
|
||||
The Simatic PG-685 is a programming device for Siemens' S5 line of industrial
|
||||
controllers. They ran PCP/M-86 and MS-DOS specially adapted for the architecture.
|
||||
|
||||
http://oldcomputer.info/portables/pg685/index.htm
|
||||
|
||||
The portable case contains a monochrome monitor (with a socket provided to
|
||||
drive an external monitor), a 5,25" floppy drive with 720KB capacity (DS,80
|
||||
tracks, 9 sectors p.t., 512 Byters p.s.) and a MFM hard disk drive.
|
||||
The PC is made up of several boards on a non-ISA bus backplane.
|
||||
|
||||
There are at least two versions and several options. The PG-685's settings are
|
||||
contained in NVRAM, and have to be updated using a testdisk if the two AA
|
||||
batteries run out.
|
||||
|
||||
For this, a key switch with a reset setting plays a crucial role. Set the key
|
||||
to reset, insert disk in drive but don't close. Switch on machine, close drive
|
||||
and set the switch to normal operation to start the setup.
|
||||
|
||||

John Elliott's kindly analyzed the ROM of this machine, his findings are represented
|
||||
in this preliminary memory map. Olivier Galibert remarked that for a 16 bit memory
|
||||
map, the address ranges have to begin on even and end on odd addresses.

This machine has the BMG (bit mapped graphics) option, that John Elliott described as a memory mapped
|
||||
hercules card. There is a GEM/3 display driver that was indeed derived from the Hercules one.
|
||||
The screen buffer starts at E000, he video card is at F9F0:80h, the beeper frequency at F9F0:36h,
|
||||
the serial port at F9F0:38h.
