Partial Feature List
- Very stable and reliable
- Includes useful set of FLEX commands and utilities
- Supports up to four virtual disks, fully cached
- Virtual disk sizes from 85k to 16 megabytes supported
- Complete set of Host-based virtual disk maintenance utilities
- Printer support via FLEX "P" command via Host printer; LPT1 through LPT4
- FLEX system time, date 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-based startup script automates logging virtual disks on
- Host environment is custom terminal look-alike - deja vu!
- Abortable so system problems cannot harm virtual disks
- "Quit" and "Abort" FLEX commands for exit from keyboard to Host
- "Flush" FLEX command to write out virtual disks immediately
- 6809 "RESET" menu command to recover control if you have an "oops".
- 6809 "NMI" for debugging purposes - clean restart after NMI
- 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
- Real Time Clock (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 NMI command
- PSYMON source code included on virtual disk
- Completely isolated from host, totally safe for experimenting
- Single/Multi-step emulation & "hot" disassembly supported
- Low Price!
