Anyone have the 2716 ePROM listing for IMSAI Basic. Version 1.4 or
whatever. I once had it, can't find my copy. If not 2716, I'll take any
listing that I can convert somehow.
Thanks

That would be the Imsai 8K BASIC? If so, I have the assembler listing
as part of the Imsai manual set.

Wait !! - there was BASIC in ROM for the IMSAI?
How was the memory laid out? What I/O devices did it expect?
Does it run with a Z80 CPU, or only the 8080?
Kindest regards,

It's in the Imsai Basic manual as a choice for loading g the software.
I had the ROM set (8 proms) but I must have overwritten them a long time
ago.
So, I wanted to make a new set, hoping someone had the eprom files avail
so I could make.
If not I will build a new setsome.other way. Does anyone have the
papertape image of IMSAI basic 1.3 or 1.4?

So I was able to get the listing for the PROMs by using the HEX file of
IMSAI BASIC 1.4 from.Rich Cini's website. I was able to then pull the
Intel papertape file image using Teraterm to capture the log of the session
while using to load BASIC into the IMSAI. I can use the log to make an
ePROM-friendly file.
Imsai 8K basic fills 0000..1FDB and stores programs from 2000, so you need
some RAM after IFFFh (8K).
My IMSAI has an IMSAI SIO serial card.

Sounds like a convoluted way to convert a HEX file into a binary file,
or whatever you mean by an EPROM friendly file. I imagine most EPROM
programmers can directly take an Intel HEX file as an input file.
If you needed a binary file, you could also use SRecord 1.65 srec_cat
to convert the Intel HEX file to a binary file, and split it up into
smaller chunks if you need to split the 8KB binary into smaller
EPROMs.

I don't remember the exact story but Dan Roganti I think had something to
do with assembling or at least mirroring the images. He made the original
eProm set we were playing with back in the 2000's.. Dan hosted his copy and

server went down and everything lost with it....I always thought *I* had a
copy hosted on vintagecomputer.net....you never know until you need it.
So, yes it would be nice if there were more copies of a pretty historic
program than just Rich's site, as reliable as it appears to have been.
I will upload a copy to vintagecomputer.net/imsai/ (for future person)

I was looking for the original prom listing format files. Not sure if
theyre 1702 2708 2716 or ??

This IMSAI 8K BASIC Version 1.4 manual says 32 chips in two IMSAI PROM
4 boards. That would be 32 256-byte 1702 EPROMs. One board starting at
address 0, the second board starting at address 4KB, and RAM starting
at address 8KB.

Sorry then, This is the assembly source listing.

Possibly the Prom-4 board with 1702s. As mentioned 2 boards = 8k. Each
chip is 256 bytes, possibly harvest the code from the listing? I'm sure
Bill is looking for someone with the image, or the chip masters.
I looked @ the listing provided, it's assembled for org 0x00. There's a
different org for CPM. So you can't use the CPM binary in rom unless
you put a rom at 0 to jump to the CPM binary, and I'm guessing it has
conditional assembly for the serial drivers.

Will be interesting to archive if someone comes up with it. Wonder if
anyone with the basics for the clone boards may have a basic which could
be used that runs on such as the Altair or Imsai clone? I know the
Altair clone has a number of alternative boot images you can select
from, could swear one is Basic, but don't have the documents handy here.

Here's a machine readable version of the 8KB Version 1.4 source code,
and a hex file of an assembled version of that code:
