There was a stnad-alone FIG forth too I think. It was bootable RX01 disk

I think I have the RT11 version of Fig Forth soemwhere, and it's pretty
obvious how to make it the stnadalone version. The only problem is doing
it, and writign the progrma fo the boot sector, etc.

If you want a really nice standalone FORTH for the PDP-11, there's
SOL-11 by Nils M. Holm. It's a bit different from standard FORTH, but
not terribly so. It is a pleasure to use; I like it very much.
I spoke with Nils about it maybe 3-4 years ago, and he is no longer
interested in maintaining it. It's interesting enough that I think it
should continue to be maintained, by someone else if necessary. In
particular, I'd love to see additional mass storage drivers written for
it, which I may tackle myself when life calms down a bit.

Would SOL-11 run on an 11/34 or a 11/04?

It will run on an 11/34, but not an 11/04. It requires EIS, which
the 11/04 lacks.
The documentation states that the author considers the EIS
requirement to be a bug.

You mean EIS; it doesn't require an EAE. But yes, I'd like to do
that as well.
It requires 28kW of RAM though. I doubt it'll be easy to trim that
down much.

Yup, that's what I meant, EIS. Been playing with -8's too much lately. It's
been a while since I messed around with SOL-11, but I didn't recall it being that big.

EIS?
8:25 p.m.
Awesome-
I will have to ask a potentially silly question - can somebody either share
the source with me, or point me to where I can download it? I have done a
Google search with no luck, except to get sidetracked drooling over the
little sol-20 computer.......
I have an 11/34 with RL01 disks, and a console..... Getting the software
onto it will be tricky!

EIS?
11:10 a.m.
I've played with SOL-11. I'd like to rewrite
it a bit so it can run on a m=
achine without EAE - there are a lot of 11/20s around with 4kW of memory. =
Do you mean EAE (which is an add-on board for any Unibus PDP11 and is
not easiy to find) or EIS (which is the extended instruciton set present
in many PDP11) here?
