Apple II Monitor on Apple 1

The Apple 1 Cassette data format uses 1 cycle of 1 KHz for a 1 and 1 cycle of 2 KHz for a zero. There is no checksum but an approximate error check can be gained from checking the last two bytes of the recording. This is pretty effective because of the data dependent record length.

Apple 1 Basics.zip

There were many versions of Apple 1 Basic provided by Apple in the early days. There was just Woz and SJ and Woz was writing Basic while the computers were being sold. When someone got a copy from SJ it was just the last stable version from Woz. I bought my Apple 1 at a Byte shop in mid 1976 and I got 4 different versions of Basic over the next 6 months or so. I labeled them version A through D. Version A did not even have an INPUT statement so about all you could do is print “HELLO WORLD”. Version B added the INPUT statement, Version C added Arrays and Version D added PEEK and POKE. I have copies of C and D but have not been able to find any earlier. The Huston brothers got a copy of Apple 1 Basic in late 1977 or early 1978 when they were employees at Apple that includes a checksum program and I presume that was the last version. By late 1976 and early 1977 Woz was focused on the Apple II. The following Excel file is a comparison of several Apple 1 Basics.

Apple II Monitor on Apple 1

Monitor Files.zip

In 2013 I was contacted by the History San Jose museum to restore an Apple 1 in their collection to
to working order. The Apple 1 was a donation that had belonged to Winston D. Gayler who was the
author of “Apple II Circuit Description” published by Sams. Dan Kottke, Allen Baum, and I were able
to get the computer operational along with one owned by Allen Baum. As a part of the material in the
Gayler collection was a program tape that contained a file of the Apple II monitor ported to the Apple
1 that he had apparently made complete with Mini-Assembler. This was not a transitional step from
the Apple 1 like the Monitor file by Steve and Allen but a port of the completed Apple II monitor
including the mini-assembler. The file was located at E500 to EFFF which makes sense for the basic
Apple 1 but prevents use of Basic. A description of available operations for the Apple II Monitor on
the Apple 1 is described in the document.

The first program file is a filtered version of the original tape.

The next file is a slightly corrected version located at E500 to EFFF that fixed a couple of minor bugs.

The Monitor is much more useful if it is relocated and it was relatively easy to write a specialized
relocation program so I generated files located at $B500 to $BFFF, $7500 to $7FFF, $6500 to $6FFF,
and $3500 to $3FFF. These have also been modified a bit more to support Basic, etc.

The last version of the program is located back at $F400 to $FEFF. This works with the FRAM board
using the VMA mod or with any system having the ability to control the $Fxxx space. With this
configuration the Apple 1 monitor is still at $FF00 to $FFFF and there is a minimum of interference
with other programs. The version at $Fxxx has been modified so that Control Q can be used to
rapidly switched between the two Monitors.
