I received this information:
I'm not sure what ATLOGO was. I might have started an Atari Logo project, but we never did any work on it. LCSI got the Atari contract, after the MIT Logo lab closed.
We now have ATLOGO; AR2 ATARI. Some interesting files, but not an implementation of Logo.

@everyfan maybe this is something for you. There's 6502 code BASIC programs. Not quite C64 of course, but close.
Looks interesting! I'd love to take a look attem
You know the secret vault with all the files, right? The PDP-10/its-vault repository. It's the file files/atlogo/ar2.atari in there. Now get the itsarc program. It's in the larsbrinkhoff/pdp10-its-disassembler repository, but if you have the its repository checked out, it's in tools/dasm.
Run itsarc -x ar2.atari
to extract the files.
It looks like some initial tests for Atari LOGO. They wrote some kind of uploader/downloader in BASIC to transfer with ITS (a comment says FTP), and a LISP program to convert binary output to text-based HEX output so they could transfer binary files to the Atari. Then, they wrote a simple machine language test in what appears to be CROSS. However, the test does not appear to be any kind of implementation of LOGO, just something to mess around with the hardware.
Folks,
Can someone explain to me what this mailing list is? What is PDP-10/its? What does it have to do with Atari?
It seems interesting, but I am confused.
I don’t think I’m on this list, I think I’m being cc’d.
Help?
Thanks Kevin

Hello @savetz,
I'm sorry if these messages come to you inappropriately. They are posted to this GitHub issue:
https://github.com/PDP-10/its/issues/964
The reason you're getting them is that @atsampson @-mentioned your GitHub name in the beginning. If I knew why, I no longer remember. He asked, "have you heard anything about an Atari Logo from MIT, or talked to anyone who worked at Atari Cambridge Research?"
Forgot to explain, PDP-10/its is the GitHub repository for the PDP-10 operating system called ITS. See the README.md for more information, or Wikipedia: https://en.wikipedia.org/wiki/Incompatible_Timesharing_System
I think these were mine and a colleague's and not lcsi staff. Ed worked on lcsi logo for the Atari. We tried at the logo lab and bid on it but lost out. I went to terrapin and supported the apple 2 logo from MIT and then on to C64 and Mac. Atari Cambridge research center was Alan Kay's lab, a lot of overlap in people with LCSI, back and forth. You know the LCSI folks so you can start there for product Atari Logo source, but it was always proprietary and never done at MIT.
Thank you.
I'd say this can probably be closed.
ATLOGO; LOGO 6, dated 1981-04-21.
.TITLE MIT Atari Logo
; Logo Language Interpreter for the Atari 800 Microcomputer,
; Written and developed by Patrick G. Sobalvarro, Leigh L. Klotz,
; and John H. Palevich with the M.I.T. Logo Group, at the Massachusetts
; Institute of Technology. It is derived from from MIT Apple II Logo
; by Stepehn L. Hain, Sobalvarro, and Klotz.
I believe @jackpal mentioned above also wrote an Atari terminal emulator supporting SUPDUP and VT52 cursor codes.
Does not assemble. It seems like a work in progress.
Hello. Is the source code of ATlogo available for public, even if it does not compile?

Hello @joaopa00,
Sorry, that file is not available. Some files with interesting background material are here: https://github.com/PDP-10/its-vault/tree/master/files/atlogo
The "ar" files are ITS archives. Use this to extract files: https://github.com/larsbrinkhoff/pdp10-its-disassembler/blob/master/itsarc.c
Ah bad news. Can you confirm that ATLogo was written in Assembly Z80?
I believe it's 6502.
I found a LOGIN file with these lines:
:tag atari
:tctyp soft hei 24 wid 39 +%tosai +%tolid +%tocid full +%tprsc no overwrite
:ttyloc Logo 327
This suggests there was an Atari (800? as above) computer in room 327, running a program capable of interpreting ITS terminal codes. I think it probably is ATLOGO; SUPDUP 1.
MAPS lists files in ATLOGO dated 1981, including ATLOGO; ATARI and ATLOGO; SUPDUP. (Compare #934, Apple II Logo.)
That's three years before LCSI's Atari Logo was released. Perhaps related to https://logothings.wikispaces.com/Atari+Cambridge+Research (link now dead, archived version):
HSTINF RECENT says "Atari Cambridge has gone belly up" as of June 1984. IOELEV lists two Chaosnet subnets belonging to Atari, and they had two MINITS machines, "System 75: Atari Sunnyvale Bridge" and "System 77: Atari Cambridge Bridge".
@savetz, have you heard anything about an Atari Logo from MIT, or talked to anyone who worked at Atari Cambridge Research?
