Atari 8bit - Operating Systems
« on: April 10, 2022, 10:09:58 AM »
Hi

I'm new here so hope to contribute format is right. Please point me to another direction. Currently going to my archive and have found some images not in TOSEC
Missing Atari OS:
NTSC Rev A very sure 197x. But the other files also have 19xx
Code: [Select]
<game name="Atari OS Rev A (19xx)(Atari)(NTSC)[400-800]">
<description>Atari OS Rev A (19xx)(Atari)(NTSC)[400-800]</description>
<rom name="Atari OS Rev A (19xx)(Atari)(NTSC)[400-800].bin" size="10240" crc="c1b3bb02" md5="a3c1585b5d19719f8acfa2b093bea75f" sha1="f821911f16ed613d72d4b255b3e68ab2d07041ac"/>
</game>

Missing late 1200XL OS Rev 11. According to Source code leak of Protoype Rev 5 for 900XLF: "Revision 11 (1200XL) Fix several problems. R. S. Scheiman   12/23/82"
Code: [Select]
<game name="Atari OS Rev 11 (1982)(Atari)[1200XL]">
<description>Atari OS Rev 11 (1982)(Atari)[1200XL]</description>
<rom name="Atari OS Rev 11 (1982)(Atari)[1200XL].bin" size="16384" crc="1a1d7b1b" md5="eacb8069c45e2ec4e0a19978bf2fc334" sha1="5833e3a51d3a966a42baea37c40c01186e8a89cc"/>
</game>

"Near East version" with arabic letters Atari OS for Atari 65XE also called 65XEN. Atari800 emulator calls it Rev 59 other 3B the chip itself has the code C101700-001A. I'm going for 3B (HEX, 59 DEC)  but feel free to change naming
Code: [Select]
<game name="Atari OS Rev 3B (1987)(Atari)[65XE]">
<description>Atari OS Rev 3B (1987)(Atari)[65XE]</description>
<rom name="Atari OS Rev 3B (1987)(Atari)[65XE].bin" size="16384" crc="45f47988" md5="d467f55fb7643553b69b34bf7e805b7d" sha1="a36b8b20f657580f172749bb0625c08706ed824c"/>
</game>

Hi,

thanks for the Info, I'll have to take a deeper look into the OS files, think I've never touched them since maintaining the Atari 8bit DATs.
