Oldie but goodie: 1"x1" CP/M system

Good Grief!

This makes the Ampro Little Board (which fit atop a 5-1/4 inch disk drive
look gargantuan.

And it's *50Mhz*!. Sigh. I *still* love cp/m even though it's a lost
cause.

Once I realized that my beloved WordStar and CBASIC required overlays to do
their magic I finally had to agree that 64K was not really enough....

cp/m lives on for me, though, in the Joe editor for Linux in the jstar
incarnation.

I think SuperCalc was the spreadsheet for cp/m but I've never used
spreadsheets...

thanks for this link.

Yeah. I was imprinted with WordStar in the mid 1980s. I've used it ever
since, both when I use it onCP/M for programming and also on Linux with
jstar. I even renamed 'jstar' to 'ws'.

One of my first tasks with a new install is to install 'joe' and then
to run 'fix.joe':

#!/bin/bash
# jvs script 2009
#
#changes joe's jstar options to ws
#
cd /usr/bin
sudo cp joe ws
cd /etc/joe
sudo cp jstarrc wsrc
# fixes crontab editorrc (for root) to be same as jstar
mv editorrc editorrc.000
ln -s jstarrc editorrc


Regards,

Jack

Cool.
Yes, that is one of the first things I install after an upgrade.

That and install a bunch of my aliaes and keybindings...C-Y = delete line,
for example.

The only thing I do with mine is play Ladder. It was the first "video
game" I ever played. :-)

Nicely done!

LADDER.COM is a BASCOM executable, meaning it was once a BASIC program
that was compiled. I have a long-term project which aims to reproduce
the source code, sans proper variable names -- of course, so that it is
100% authentic. I've done some work with BASCOM and IDA to suss out how
it compiles code, but I'm far short of an automated decompiler.

OT, but I'm thinking of writing/converting Nils's source text to DOS x86
asm;- it doesn't look as if there's a DOS port out there (Javascript
doesnt count, IMO!).

BASIC source would have been portable, but it doesn't seem to be
available.

There is a DOS .COM file in the archive [1] and the same source code
compiles to DOS, CP/M, and Unix executables without any changes. All
you need is a T3X/0 compiler [2]. There are pre-compiled compilers for
DOS and CP/M on the homepage.

Interesting! Never had a closer look at LADDER.COM. Good luck with the
project! If you are just looking for a hackable LADDER-like game, the
source code for my version is in the archive. :)
