I have my Imsai 8080 fully running and communicating with my Mac Pro as a
dumb terminal. Many thanks to this group for helpful pushing along the way..
I have also modified SCS1, the Imsai monitor program, to my liking and have
it burned into PROM. Since I do not yet have a floppy system for this
antique, I wrote an Intel hex format loader and just send the hex files over
the serial line to load them.
Life is good.
What I am looking for now is the 8080 asm source code to a good 8K basic
interpreter. I found one called TinyBasic but it was so concerned with
space the author built in a ton of self-modifying code and trying to follow
the logic is like untying a plate of spaghetti. I have another one called
BASIC85 which is better but assumes a VIO memory-addressable video system.
If necessary I will take this one apart and make it work. I hear a lot
about Imsai having an 8K basic, and I can find the manuals, but I can?t seem
to locate the actual 8080 source.
Anyone out there know of or have the asm source code to a basic interpreter
or know what became of the Imsai Basic8K?
There are a pot load of BASICs on the net in source form.
One can be found on the Dave's old Computers [Dave Dunfield]. Others are
around try looking for LLL Basic. Tinybasic is a good one really despite
appearances as it was from my memory romable [There were several different ones].
Get back with what you find. I do have LLL and a version of PT 5K basics in my
archive and I got them off the net.
