TASMx: Arcade Assembler Program
TASMx is a program based off of Thomas Anderson's TASM shareware assembler. I needed an assembler that
could handle macro expansion plus be customized for the special Williams Pinball Macro Instruction Set and
mimic the old Atari PDP-11 and VAX based Macro-11 Assembler. Since I didn't want to do this from scratch, I
decided on Thomas Anderson's TASM because I could register it for $40 and get the source code. TASM is an
extremely flexible assembler that will work with all the classic arcade processors right off. In order to
add some more functionality, I added some features to the assembler directives... mainly the ability to
'pull' and 'push' data onto a stack within the assembler. Be sure to read my addendum's to Thomas' Documentation
for an explanation of these.
Note: TASM is shareware as described on Thomas Anderson's homepage at http://home.attbi.com/~tasm/.
While TASMx is available here to download, you still need to agree to the terms of his license.
Some Features
Because TASMx is a macro assembler it is *extremely* flexible to meet your needs. Once of the major enhancements provided by
writing some macros is that it now supports simple C style logic and loops. If you have programmed in assembly you can
appreciate how this will eliminate hundreds of local labels.

TASMx Documentation
Firstly, you should refer to the new documentation....
Original Documentions specific to TASM is located at the Squak Valley Software Homepage..
Here are the #include files I have created for easier programming... NOTE: These will not work on the standard
TASM assembler as they utilize the .push and .pull assembler directives only available in TASMx. See below to
do download TASMx.
Download
This downloadable .zip file contains all of the Standard TASM files. The only changes are
that the TASMx executable is included and the TASMx User's Manual has replaced the original.
