as Macro 11
source), it wouldn't be _too_ difficult to modify the I/O drivers, I
think.
A quick Google search recovered this as the first item:

SOL-11 - A Small Language and OS for the PDP-11
SOL is a small, non-standard, stand-alone FORTH kernel containing
everything that is required to edit, store, recall, compile, and run
programs on PDP-11 microcomputers. It is intended for a minimum
operating system and programming environment. The FORTH language offers
full access to the complete hardware. Device drivers for the console and
some block devices are included.
Supported Hardware
* PDP-11 CPU with EIS (required)
* 8K to 28K words of memory
* console terminal (preferrably VT100)
* RX01/RX02 floppy disk drives
* RL02 disk drive
* TU58 tape drive
The Sources
SOL is written in PDP-11 assembly language and FORTH. The BTN11
assembler (version 0.9 or later) is required to compile the assembly
part of SOL.

Seems like what the doctor ordered. Check out the rest of the site for
other interesting projects.
