!!!MAC/65 Macro Assembler; Copyright Stephen D. Lawrow; OSS, Inc.; ICD, Inc. &amp; FTe

MAC/65 is a 6502 macro assembler written by Stephen D. Lawrow and originally sold by [Optimized Systems Software|https://en.wikipedia.org/wiki/Optimized_Systems_Software] for the Atari 8-bit computers. It was first released on disk in 1982, then later on a 16 KiB bank-switched 'SuperCartridge'.

MAC/65 along with other OSS products became part of ICD's catalogue of Atari products in January 1988. In 1994, Fine Tooned Engineering obtained limited rights to ICD's 8-bit products, including MAC/65.

MAC/65 was initially developed as a disk-based program. It replaced an earlier assembler, [EASMD], in OSS's product portfolio. The first version, 2.00, was released in 1982.

The MAC/65 disk also included a debugger, [BUG/65|BUG65], developed by McStuff Company. The disk also contained a DOS; initially it was [OS/A+|OSS OS-A+], later replaced with [DOS XL|OSS DOS XL].

!!MAC/65 2.00 (1982)

This is the first disk version, released in 1982.

!!MAC/65 4.20 - FTe re-release (1994)

After Fine Tooned Engineering obtained rights to MAC/65 from ICD, they re-released version 4.20 in 1994, as shareware to be used exclusively with the [PC Xformer] emulator. The disk contained additional documentation files and the program had modified copyright text, but was otherwise identical.

!!Patches from OSS Newsletter

MAC/65 4.20 was not without bugs. OSS published a few patches for it in their Summer 1983 newsletter:

%%(float:left)[{Image src='MAC-65-patches-Summer-1983-1.jpg' width=200 caption='Newsletter patches - page 1' link='attach/Mac65/MAC-65-patches-Summer-1983-1.jpg'}]%%

!!!Cartridge versions

After version 4.20, Lawrow rewrote MAC/65 for cartridge medium. It utilized OSS's own &quot;SuperCartridge&quot; - a 16 KB bankswitched cartridge that occupied only 8 KB of Atari memory, and could be disabled or enabled at will. It provided much more comfortable experience than the disk version. MAC/65 cartridges were produced using both two-chip and one-chip variants of the SuperCartridge.

The cartridge version replaced BUG/65 with another debugger - [DDT] (Dunion's Debugging Tool) developed by James J. Dunion.

!Source code
In 2017 AtariAge user Alfred published source code for MAC/65 1.01 that he had obtained from ICD back in the day.[2] Dated 1988, the sources are in the format of Mike Gustafson's cross-assembler that was used internally at ICD. When ICD bought the rights to OSS portfolio, they apparently converted the sources from their original MAC/65 syntax to ICD's cross-assembler.

!!!MAC/65 ToolKit

OSS offered a companion disk to MAC/65. MAC/65 ToolKit was sold either separately or in bundle with MAC/65, and contained a collection of helpful macros and routines implementing various common operations. The ToolKit supported both disk and cartridge versions of MAC/65.

!!!Later work-in-progress versions
Although version 1.02 was the last one published commercially, Stephen Lawrow continued development of MAC/65 - he kept fixing bugs and adding new features, all ultimately unpublished.

In 2016, the AtariWiki team received a set of microfilms from an anonymous source,[3][4] that contained hex printouts of source listings of 3 different versions of MAC/65. Through the painstaking process of digitizing the microfilms, the team managed to recover the original files, and combined them into ATR images provided below.

Note: while source files and binary images in the provided ATR images were restored from microfilms, the other contents of the disk images - e.g. DOS files - were added by the AtariWiki team for convenience.[5]

!! MAC/65 1.01 (1986)

! Source code
* MAC/65 1.01 (1986) source code (See [A call for help|Mac65#ACallForHelp] below):
** [Disk 1 (master)|mac-xl-master-icd.atr]
** [Disk 2 (slave)|mac-xl-slave-icd.atr]

This version, despite identifying itself as MAC/65 1.01 on the title screen, is actually a later development; comments in the master source file (NEWMAIN) identify this version interchangeably as &quot;MAC XE&quot; and &quot;MAC XL&quot;, with the copyright year of 1986. This version is different than the commercially-released v. 1.01 (or any released version, actually), although the actual functional differences are yet to be investigated.

The sources are in MAC/65 format; they may be built using MAC/65 1.02. Two disk drives are needed. The master diskette should be placed in the D1: disk drive, and the slave diskette in D2:. The master source file is D2:NEWMAIN. Change RAM to 0 and EPROM to 1 in D2:NEWMAIN (lines 190-200) and then assemble from RAM to disk, by entering:

{{LOAD #D2:NEWMAIN\\
ASM ,,#D2:NEWMAIN.OBJ}}

The resulting file NEWMAIN.OBJ is a binary DOS file that loads itself into the $3000-$6fff area; these are the 16 KB ROM data for the two-chip variant of the OSS SuperCartridge. To build a ROM image for the one-chip variant, additionally change BANK2 to $D509 and BANK3 to $D501 in D1:EQUATE.INC (lines 180-190).

!Cartridge images
Here are cartridge images created by building the sources.

!! MAC XE 3.4i (1986-02-11)

The &quot;slave&quot; source disk of MAC/65 v. 3.6 (described in a [later section|Mac65#MAC653.619880107]) contains a file named MACXE.EPR, which is an assembled binary of a version of MAC/65 that identifies itself as &quot;MAC XE version 3.4i&quot; with the date 2/11/86.

[{Image src='MAC_XE_3.4i.jpg' width=440 caption='MAC XE v.3.4i start screen'}]

This version is identical to the &quot;Assembler v. 3.4&quot; version (described in the [next section|Mac65#Assembler3.419871221]), the only difference being the text on the start screen. To build a version that is identical to MACXE.EPR, take the sources of Assembler 3.4 and change the lines 40-70 of D1:COPY:

{{40 MES   .BYTE $7D,&quot;MAC XE&quot;,TAB,TAB\\
50       .CBYTE &quot;Version 3.4i&quot;\\
60 MES1  .BYTE &quot;(c) 1985 Stephen D. Lawrow&quot;\\
70       .CBYTE &quot;   2/11/86 &quot;,TAB\\}}

** [Disk 1 (master)|mac-xl-1.atr]
** [Disk 2(slave)|mac-xl-2.atr]

This version of MAC/65 presents itself on the title screen as &quot;Assembler version 3.4&quot; with date &quot;12/21/87&quot;. It is currently unknown what are the functional differences between this version and the other ones.

The sources are in MAC/65 format; they may be built using MAC/65 1.02. Two disk drives are needed. The master diskette should be placed in the D1: disk drive, and the slave diskette in D2:. The master source file is D1:MASTER. Change RAM to 0 and EPROM to 1 in D1:MASTER (lines 190-200) and then assemble from RAM to disk, by entering:

{{LOAD #D1:MASTER\\
ASM ,,#D1:MASTER.OBJ}}

The resulting file MASTER.OBJ is a binary DOS file that loads itself into the $3000-$6fff area; these are the 16 KB ROM data for the two-chip variant of the OSS SuperCartridge. To build a ROM image for the one-chip variant, additionally change BANK2 to $D509 and BANK3 to $D501 in D1:EQUATE.INC (lines 180-190).

As noted in the [previous section|Mac65#MACXE3.4i19860211], the resulting file MASTER.OBJ differs from the MAC XL 3.4i binary (found on the MAC/65 v. 3.6 source disks) only in the copyright text.

This version of MAC/65 presents itself on the title screen as &quot;MAC/65 version 3.6&quot; with date &quot;01/07/88&quot;. Judging from the dates in the source code, this is chronologically the last known version of MAC/65. It is currently unknown what are the functional differences between this version and the other ones.

The &quot;slave&quot; source disk also contains a file named MACXE.EPR, which is an assembled binary of MAC XE 3.4i (described in an [earlier section|Mac65#MACXE3.4i19860211]).

The sources are in MAC/65 format; they may be built using MAC/65 1.02. Two disk drives are needed. The master diskette should be placed in the D1: disk drive, and the slave diskette in D2:. The master source file is D1:MASTER. Change RAM to 0 and EPROM to 1 in D1:MASTER (lines 190-200) and then assemble from RAM to disk, by entering:

!!!A call for help

The source files of the work-in-progress versions of MAC/65 have not yet been analysed. It is unknown what are the new features introduced in each of the following versions:

* [MAC/65 1.01 (1986)|Mac65#MAC651.011986]
* [Assembler 3.4|Mac65#Assembler3.41987-12-21]
* [MAC/65 3.6|Mac65#MAC653.61988-01-07]

Comparing source codes of these versions to each other, and to the [source code of the released version 1.01|Mac65#SourceCode], would allow to discover the new features and document them. Yotta-thanks to all who help us here.
