DX-Forth v3.90 - Forth compiler for
MS-DOS (07-Aug-09) 
- DX-Forth is a 16-bit direct-threaded Forth-94 compiler.
Most utilities on this page were written using DX-Forth
so you will need this compiler should you wish to modify
them. For all IBM-PC compatible machines with MS-DOS 2.x
or better.

- HEXBIN v0.1 - Hex/binary
conversion utility (8-Dec-03)
-
- HEXBIN is a general purpose hex-binary conversion utility.
-
- It will accept a raw ascii-hex or binary file and convert
it to binary or hex.
- Output may be in one of the following formats:
- - binary
- - unformatted hex (raw)
- - formatted hex (Intel, MOS Technology or Motorola)

- KCS v0.8 - Kansas City Standard and
CUTS tape decoder/encoder (28-Jan-06)
-
- This is for all you old-timers that still have computer
programs on cassette!
-
- One of the most popular early ways to store computer
programs on audio cassettes was the Kansas City Standard
(also known as the 'BYTE standard'). Developed in 1975,
it uses an encoding scheme where a '0' bit is represented
as 4 cycles of 1200Hz and a '1' bit as 8 cycles of 2400Hz.
The data rate is 300 bits per second. Computers which
used the Kansas City Standard include S100-based systems,
PT SOL-20, Ohio Scientific C1P/Superboard II, Compukit UK101,
Acorn ATOM and many others.
-
- The KCS utility allows programs stored on cassette tape
using either the Kansas City Standard or CUTS (Processor
Technology Computer Users Tape Standard) to be decoded to
a program file. The reverse process - converting a
program file to an audio wavefile is also possible,
allowing one to produce perfectly regenerated cassettes.
KCS works with 8-bit mono WAV, VOC or RAW audio files
recorded at 22050 samples per second. A variety of serial
formats are allowed including 7 or 8 bit data, 1 or 2
stop bits, odd/even or no parity.

- KIMTAPE v0.5 - tape conversion
utility for KIM-1 and SYM-1 (17-May-04)
-
- Similar to the KCS utility for Kansas City Standard
tapes, KIMTAPE allows programs stored on cassette tape to
be decoded to a program file. It handles both MOS
Technology KIM-1 and Synertek SYM-1 tape formats
including HYPERTAPE. The reverse process - converting a
program file to an audio wavefile is also possible,
allowing one to produce perfectly regenerated cassettes.
KIMTAPE works with 8-bit mono WAV, VOC or RAW audio files
recorded at 22050 samples per second.

MORSE v0.2 - Morse trainer
(14-Jul-03)
- MORSE takes any ascii text file and sends it to the PC
speaker as a stream of Morse code characters. Output may
be redirected to a WAV or VOC sound file for dubbing to
an audio cassette. The speed can be varied from 5 to 40
words per minute. The character speed may be set higher
than the send speed (the "Farnsworth method")
to aid learning. MORSE is also able to generate practice
files consisting of groups of random characters.

TRACK v0.1 - 3-point tracking
calculator for LC tuned circuits (3-Aug-03)
- A three-point tracking calculator to help minimize
tracking errors associated with the design of
superheterodyne circuits. It may also be used to improve
the scale linearity of single tuned circuits.

RESISTOR v0.1 - parallel
combination selector (22-Sep-02)
- A program that allows the user to enter a resistance
value and tolerance and then select a matching
combination of parallel resistors from the E12 or E24
series of preferred values.

SOLENT v0.2 - a conversion utility
for KCS and SOL-20 users (13-Oct-03)
- SOLENT is a companion to KCS - a
utility to decode/encode "Kansas City Standard"
and Processor Technology "CUTS" cassette tapes.
-
- Processor Technology's SOL-20 and CUTER-based systems
store programs to tape in a special format. As KCS simply
dumps all data found on a tape, a utility is required to
convert KCS tape binary files into ENT format for use on
a SOL-20 or the Solace
emulator. SOLENT can also be used to create Processor
Technology tapes from ENT files without recourse to a
real machine!

OSI LOADER v0.2b - Convert OSI binary
files to hex loader format (9-Oct-03)
- These days it is much easier to write machine code
programs using a cross-assembler on
the IBM-PC and transfer the binary to the target computer
for testing. OSI LOADER converts binary files to Ohio
Scientific hex loader format which can be sent serially
to an OSI computer.

A65 v1.11 - 65C02 Assembler
(15-Jan-09)
- A65 is a cross-assembler for the 65C02 microprocessor. It
is specifically designed to assemble source files written
using standard MOS Technology assembler syntax. Includes
Turbo-C source.

ASM48 v1.2 - 8048 Assembler
(25-Sep-02)
- ASM48 is a cross-assembler for the MCS-48 and UPI-41
series of microcontrollers. Devices supported include the
8035, 8039, 8048, 8748, 8041 and others.

- A version for CP/M-80 is available here.
20KHz Bandpass Audio Filter
(26-Jan-04)
- A general audio filter with a 20Hz to 20KHz response and
24 dB/octave slope. Its purpose is to remove frequencies
outside the audible range. It is particularly useful as a
pre-filter for audio sampling applications, where it will
remove sub-sonic rumble and provide anti-alias filtering.
