§ 2 - Partial Feature List

• Very stable and reliable
• Includes useful set of FLEX commands and utilities
• VDisk subsystem
  • Supports up to four VDisks, fully cached
  • VDisk sizes from 85 k to 16 MB supported
  • Complete set of Host-based VDisk maintenance utilities
  • Host-based startup script automates logging VDisks on
  • Abortable so system problems cannot harm VDisks
  • "Flush" FLEX command to write out virtual disks immediately
• Printer support via FLEX "P" command via Host printer; LPT1: through LPT4:
• FLEX system time, date (but Y2K!) set from Host clock on startup & optionally once/minute
• Vintage color graphics subsystem from a real arcade machine, with games
• 2 editors, BASIC, Forth
• Assembler, disassembler, utilities, much more
• Host environment is custom terminal look-alike — deja vu!
• "Quit" and "Abort" FLEX commands for exit from keyboard to Host
• 6809 RESET menu command to recover control if you have an "oops"
• 6809 NMI event for debugging purposes — clean restart after NMI command
• IRQ handling & regular source of IRQ interrupts
• Well documented (assuming you know how to use FLEX, that is)
• Memory efficient operation (but watch those disk sizes!)
• Full-boat 63k RAM 6809 virtual machine
• plus 2k virtual ROM
• ACIA Serial port emulation @ $E004/$E005 & "mirror" @ $E008/$E009
• Can also use serial port of Win95/Win98 PC as "remote" port ACIA for 6809 comms
• RTC hardware emulation for access by 6809 software
• Virtual "front panel" (computers have to have lights, don't they? Of course...)
• Complete 6809 instruction set emulation (except CWAI & SYNC)
• Emulates SOROC IQ-140 terminal (so screen editor can work)
• Virtual DIP switches & LEDs for use in your own programs
• Runs at about 3.4 MHz 6809 equivalent on a 133 MHz Micron Pentium
• Traps on all illegal opcodes (they convert to SWI, $3F)
• PSYMON monitor runs on "Mon" command or menu RESET command
• PSYMON dumps registers on menu NMI command
• PSYMON source code included on virtual disk
• Completely isolated from Host, totally safe for experimenting
• Single/Multi-step emulation & "hot" disassembly supported
