Usage

MESS will emulate one of the following Apollo workstations and servers:

To run an Apollo emulation start MESS with one system and additional command line options, e.g.

 $ ./mess dn3500 -mouse -log -disk1 <pathname>.awd -flop <pathname>.afd

Useful command line options:

• -mouse - grab mouse input (for acceptable mouse emulation; use this option only for the DN3x00 emulation)
• -mt - use a second CPU core for video processing (may improve the graphic performance)
• -nothrottle - disable throttling to omit sound problems (in openSUSE 11.3)
• -nosound - turn off the keyboard beeper
• -log - error messages will be logged in error.log
• -disk1 <pathname>.awd - to specify an Apollo Winchester Disk image file
• -disk2 <pathname>.awd - to specify the second Apollo Winchester Disk image file
• -flop <pathname>.afd - to specify an Apollo Floppy Disk image file
• -ctape <pathname>.act - to specify a cartridge tape image file

Be sure to set the following options in mess.ini or as command line option

Driver Configuration

The Apollo Driver Configuration menu has the following entries

20 Years Ago ... and Node ID from Disk should normally be on, all others should be off.

Misc

An image file of an Apollo floppy disk or of an Apollo Winchester disk may be used to run the Apollo standalone utilities or to boot Domain/OS. If no image file is available, the build-in netserver emulation may be used to run the Apollo standalone utilities. To setup the netserver directory tree

• use the following commands to backup the necessary files on your Apollo workstation:

 # cd /
 # tar cf /tmp/netserver-files.tar sau7 sau8 sau_sys sys/net/netboot sysboot

• copy the backup file /tmp/netserver-files.tar to your Linux system (e.g. with rcp)
• on your Linux system, create the directory apollo/roms/apollo and untar the files, i.e.

 $ cd <your emulation directory>
 $ mkdir -p apollo/roms/apollo
 $ (cd apollo/roms/apollo && tar xf /tmp/netserver-files.tar)

• start the DN3x00 emulation in service mode and try the following commands in the MD

 > di e
 > ld
 > ex config

Notes:

• the netserver base directory is hardcoded as <rompath>/apollo resp. apollo/roms/apollo
• any other backup file (e.g. any ancient wbak file) may be expanded in apollo/roms/apollo

Keyboard

• Function Keys

Set Num Lock to use the Function keys F1 - F9 and F10 = F0 without Apollo mapping.

• Other Keys

• Cursor keys and Pad scroll keys have been mapped to the numeric keypad too.

BIOS options

The Apollo emulation will use the following ROM image files in ROM path <rompath>/dn3500:

• 3500_boot_12191_7.bin
• 3000_boot_8475_7.bin
• 5500_boot_a1631-80046_1-30-92.bin
• 3000_3c505_010728-00.bin

refer to http://www.bitsavers.org/bits/Apollo/firmware/

Note: ROM image file names must be converted to lower case unless they are zipped into zip file <rompath>/dn3500.zip

RAM options

RAM is configured with fixed size in MESS

• 16 MB for DN3500 and DSP3500
• 8 MB for DN3000 and DSP3000
• 32 MB for DN5500 and DSP5500

Controllers

MESS supports the emulation of the DN3500, DN3000, DN5500, DSP3500, DSP3000 and DSP5500 with

• 1280x1024 (19"), 1024x800 (15") or no monochrome display
• a 3COM 3C505 Ethernet Adapter and a NETMAN emulation
• an OMTI 8621 controller with one or two 156 MB (or 348 MB) Micropolis disk image file
• an Archive SC499 Cartridge Tape Controller with one 1/4-inch cartridge tape image file
• a floppy drive with a 1.2 MB image file

Known Issues

• Apollo Emulation
  • memory size not configurable (currently fixed at 16 resp. 8 MB)
  • netserver base directory is not configurable (currently hardcoded as <rompath>/apollo resp. apollo/roms/apollo)
  • hard disk image file is hard to create (should provide cpdisk to make disk image files similar to /systest/ssr_util/cpflp, see also rwvol)
• M68K Emulation
  • M68K FPU is only partial implemented; missing operations or operands may terminate (i.e. crash) the emulation
  • M68040 MMU is not yet implemented (ex domain_os will crash with Segmentation fault for DN5500)
• see separate file for more issues
