Rarity 10 and above up to impossible#

This chapter is intended to make an outlook for programs which must exist, but seem to be lost over the decades. If you have any hint, idea or whatever else to help us to digitize this for generations to come, please let us know.


•) Atari OS Rev. B (PAL) for Atari 400/800 from 1981 ; PRINT PEEK (65528)  <RETURN> => 34

There are more than rumors about this OS type, please see here:

Atari XL OS full searchable size: 14.8 MB

Page 31 in the PDF-file or page 28 in the manual itself.

If you own an Atari 400 or 800 in the PAL version, please do us a favor and enter:

?PEEK(65528)

in BASIC. If the result is 34, then you own the most expensive Atari in the world, which has an OS we do not have up to today. It is only a little step for you, but would be a giant leap for the Atari community. Everlasting fame is sure for you in that case.

Further we are looking for:


•) OPERATING SYSTEM 255 for Atari 400/800 ; PRINT PEEK (65528)  <RETURN> => 255

Many thanks to kr0tki who found the trace, that the OS 255 is for real! In page 8 of:
All about Cassette Tapes from 1979.pdf(info) ; size: 741 KB we find:

•) From The Atari Accountant Series just:

•) Atari The Dow Jones Investment Evaluator
Atari Dow Jones Investment Evaluator CX8124
Atari Dow Jones Investment Evaluator CX8125
Atari Dow Jones Investment Evaluator CX8127

•) Atari Home Finance or Personal Finance

•) Atari Learning System Software ; complete missing!


•) Desperate call for help on missing Dorsett tapes

Some tapes had severe damage and therefore couldn't be digitized. If anyone is in the possession of the following tapes, please give us a message or a post here. We really need your help and appreciate just any hint on the programs, who seem to be lost in time, like tears in rain.

The left ones to digitize are as follows:

- General Shop Practices:

Oa1 Tool Identification Lesson, Part 1
Oa7 Discussion of a Two-Cycle Engine
Oa8 Use of Micrometers and Calipers

- Health Services Career:

Hc5 Medical History
Hc6 Extended Care

- Physics:

Ph16 Theory of Relativity

Well, concerning Physics, we may can restore Ph16 from the Atari-Version of that course, Physics CX6008? Just loud thinking...


•) Atari Assembler Editor Cartridge Source Code

•) Atari Macro Assembler (AMAC) and Program Text Editor Source Code

•) Atari Editor CX8105 (maybe replaced by the Atari Program Text Editor?)

•) Atari Statistics II CX8112 Disk (was it ever finished?)

•) Atari Pascal
CXL4017 Pascal (cartridge, planned, but never released)
CX8109 Pascal (planned, but never released, because 128 KB RAM and 2 disk drives were needed)
CX8110 Pascal Database (planned, but never released, because 128 KB RAM and 2 disk drives were needed)
CX8115 Pascal-Native Code (planned, but never released, because 128 KB RAM and 2 disk drives were needed)
CX8116 Pascal-Linker (planned, but never released, because 128 KB RAM and 2 disk drives were needed)

•) Synapse Software: SynMail; was finished according to Steve Hales, but after SynCalc und SynFile+ never sold to the public. So, somewhere out there, it may exists

•) Synapse Software: SynText; was finished according to Steve Hales, but after SynCalc und SynFile+ never sold to the public. So, somewhere out there, it may exists

•) Synapse Software: SynTax; ever shipped? Status, as of 2015, is complete unclear.


•) Kyan Pascal: The community with the help of all has made great progress regarding Kyan Pascal. Tom Eckmann, CEO of Kyan Pascal, was so nice to us, by giving Kyan Pascal into PD. To complete Kyan Pascal, we need your help again. The missing list is as follows:

- Kyan Pascal version 1.2 and 1.3
- Programming Utility Toolkit for Kyan Pascal version 1.x
- Advanced Graphics Toolkit for Kyan Pascal version 1.x
- Kyan Pascal version 2.00 and 2.03
- Code Optimizer Toolkit for Kyan Pascal version 2.x ; includes the source code for the Runtime Library

Please take into account: the System Utilities Toolkit for Kyan Pascal version 2.x is labeled as Version 1.00, while the content is 2.x! Therefore, if you have any original diskette from Kyan Pascal, please let us know. Thank you so much in advance. :-)

German Atari software#

•) Atari Music Spiele
Hierzu ist zu sagen, dass bis heute keine Version öffentlich bekannt ist. Ferner ist noch nicht einmal eine Boxenhülle als Bild vorhanden. In keinem Katalog, noch in einer Preisliste oder in einem Handbuch wurde hierzu eine Spur gefunden! Dennoch kommt die Information aus einer sehr seriösen Quelle, die wir ernst nehmen. Sollte jemand im Besitz dieser Software sein, würden wir uns über eine Rückmeldung sehr, sehr freuen. :-)

•) Atari Himmelschreiber RX8059 oder DXG 5704

•) Super Biorythmus (wurde es je fertig?)

•) Atari Datenbank DXG 5723 Copyright © 1983 Atari Elektronik Vertriebs GmbH
Hierzu ist zu sagen, dass bis heute keine Version öffentlich bekannt ist. Ferner ist noch nicht einmal eine Boxenhülle als Bild vorhanden. Es kann sich jedoch um die deutsche Version von SynFile+ handeln, welche exklusiv für Atari entwickelt worden ist. Das Jahr 1983 stimmt, ferner wird das Basic-Modul benötigt, auch das stimmt hier. Sollte jemand im Besitz dieser Software sein, würden wir uns über eine Rückmeldung sehr, sehr freuen. :-)

•) ATA MON DXG 5724 Copyright © 1983 Atari Elektronik Vertriebs GmbH
Version 1.0 von J. Rued haben wir, jedoch keine Anleitung bzw. Handbuch. Sollte jemand im Besitz dieser Software sein, speziell Version 1.3, würden wir uns über eine Rückmeldung sehr, sehr freuen. :-)

Bzgl. der beiden nachfolgenden Programme ist unklar, ob diese einfach 1:1 von der US-Version übernommen worden sind oder tatsächlich eingedeutscht worden sind? Ein Foto vom Inhalt der Diskette oder gar eine Prüfsumme CRC oder MD5 würde uns hier sehr, sehr helfen. :-) Vielen lieben Dank für die Hilfe vorab. :-)

•) Atari Pascal DXG 20102 ; wurde das englische Atari Pascal bzw. APX Pascal nur 1:1 kopiert oder gar ins Deutsche übersetzt?

Und als letztes noch das Modul, welches für den WDR hergestellt worden ist:

•) WWF-Club-Spiel - A cartridge used by German Television in the 80's for a call-in game via telephone - programmer has lived in Hattingen/Germany
