68K was reserved for FlexOS 68K, presumably derived from Concurrent DOS 68K as of 1986. A CP/M API front end (FE) was available as well, using the extension. FlexOS 286 executables using the system's native INT DCh ( INT 220) application program interface had the filename extension. The original protected mode FlexOS 286 version 1.0 was designed for host machines equipped with 286 CPUs, and with adaptations for NEC V60, NEC V70 and Motorola 68000 processors planned.

Made for fairly compact code and reasonable execution speed.FlexOS was re-written in C for higher portability across hardware platforms, and it featured very low interrupt latency and fast context switching. BASIC09 compiled into "p-code" which was interpreted at runtime. I don't think we had a native assembler and BASIC09 ran under OS/9.
The programming we did was mostly BASIC09 and a little assembly. A step short of a C compiler (which we didn't have) but made coding a little cleaner. And in case you're wondering, a structured assembler has macro like instructions for common programming structures such as IF THEN ELSE and DO WHILE. HP had a universal assembler tool that managed all the common tasks (symbol recognition, hash table, etc.) so all I had to do was handle the stuff unique to the structured assembler. One of the fun projects I did was create a 6809 structured assembler for the development system.

Peatman worked at HP during the summer so we had a lab full of HP development systems tied together on a IEEE-488 'network'. Probably helped that Motorola donated to the college. John Peatman, was a big Motorola supporter. The microprocessor professor at Georgia Tech, Dr. I have to agree on that point! And it was one of the last of the separate processors.

I'm looking for a software person to help with a ROM monitor and work on the OS, If you think that is something you would like to try, please post. I've also added the USB File Manager module schematic. There is an expansion bus so more stuff can be added later.

There is some interesting I/O on board - a stereo sound generator circuit and an Arithmetic Processing Unit (APU), along with two serial ports and two parallel ports. This will also require modifications to the OS, if OS/9 is used. Also there is a USB interface so a flash memory stick can be used for mass storage. I'm sure that will require some modifications to the OS to handle the MMU. I was hoping that this board will be able to run OS/9. There will definitely be software required to manage the MMU. Although it's not a flat linear memory map, it's a lot to work with. This design includes a Memory Management Unit (MMU) so the CPU has an address space of 8MB. I think I've gotten it right, but that usually means there are a couple of nasty bugs I'm overlooking. I would be interested in hearing from anyone interested is helping out, or just has an opinion to share. I've been working on a 6809 Single Board Computer design and I wanted to share it with the community.
