# OF816
|
|
OF816 is a [65C816](https://www.westerndesigncenter.com/wdc/w65c816s-chip.cfm)
|
|
Forth implementation heavily inspired by
|
|
[Open Firmware (IEEE 1275-1994)](https://www.openfirmware.info/Welcome_to_OpenBIOS).
|
|
|
|
Note that OF816 is *not* an Open Firmware implmentation (yet), but it has the
|
|
potential (and groundwork has been done) for it to become one.
|
|
|
|
## Features
|
|
|
|
Among its many features are:
|
|
* Mostly platform-independent. OF816 can be ported easily to new systems.
|
|
* Ports currently exist for the W65C816SXB, Neon816, and the Apple IIgs.
|
|
* New ports require the implementation of a handful of routines.
|
|
* Simple instantiation of one or more Forths in a system.
|
|
* 32-bit cells.
|
|
* Optional [FCode](https://www.openfirmware.info/Forth/FCode) support
|
|
(less Device Tree and Package functions).
|
|
* [ANS Forth](http://lars.nocrew.org/dpans/dpans.htm)
|
|
* Core, most of Core Ext, Exception, Search Order, and Search Order Ext word
|
|
sets.
|
|
* Smattering of words from other sets.
|
|
|
|
## Goal
|
|
|
|
The goal of OF816 is to help get 65C816-based projects off the ground in terms
|
|
of development and testing. With a little effort it can be brought up on a new
|
|
system and used to play around with new hardware.
|
|
|
|
OF816 is not designed for speed. While reasonably performant, the primary goal
|
|
was compatibility with 32-bit Open Firmware's core word set, cell size, and
|
|
FCode. This allows the possibility of re-using existing Forth source and FCode
|
|
to develop hardware drivers, and potentially developing OF816 into a full Open
|
|
Firmware implementation.
