Assembler Editor - revision A & B cartridges - outlook for revision C and maybe D#

After more than three decades, another different version of the cartridge was discovered and could be verified, please see the md5 checksum below. AtariWiki dares to define them as revision A and B in analogy to the Atari Basic cartridge, which was delivered in three different versions. It is easy to find out, which version one has, just type in ASM and hit RETURN. If you have a revision A cartridge, no error message is shown, in case you have a revision B cartridge, the amount of errors are shown. Please see the two pictures below:

Assembler Editor - revision B cartridge test result

In the future all bugs shoud be collected and if they can be fixed, a revision C is thinkable. If we go far ahead of this, then even an interbreed with the TURBO-BASIC XL source code is thinkable. In 1985 this was done for the Atari Basic cartridge by Frank Ostrowski and because of many code routines are similar, there is great chance to achieve this. Of course, even a renaming of the cartrige is possible, AtariWiki suggest to call it: 'Atari Turbo-Assembler Editor'. ;-)
