-
- Applix 1616 computer
-
- See for docs: http;//www.microbee-mspp.org.au
-
- First revealed to the world in December 1986 issue of Electronics Today
- International (ETI) an Australian electronics magazine which is now defunct.
-
- The main articles appeared in ETI February/March/April 1987, followed by
- other articles in various issues after that.
-
- Current Status:
- After 60 seconds, boots to the ramdisk. You can enter commands.
- If you have a floppy mounted, it will boot from the disk.
-
- The system could support 1 or 2 5.25 or 3.5 floppy drives, although 3.5
- was the recommended hardware. Format is similar to the PC 720kb, except
- it has 5 sectors of 1024 bytes, giving 800kb total. We only support the
- 3.5-sized disks.
-
- TODO:
- - Cassette interface (coded but not working)
- - Use kbtro device (tried and failed)
- - Optional serial device Z8530 Z80SCC
- - Optional SCSI controller NCR5380 and hard drive (max 40mb)
- - Joystick
- - Audio: it could be better
- - DAC output is used to compare against analog inputs; core doesn't permit
- audio outputs to be used for non-speaker purposes.
- - Bios 5 crashes mess after scrolling about half a screen
