On the Utilities page I have two programs to convert to MOS Technology papertape format: KIMpaper, a command line utility, and ConvertHexFormat, a GUI app.
All in Freepascal/Lazarus source format, and tested on Linux (Raspberry PI OS) and Windows 10 64 bit. So the programs will run everywhere Lazarus is available (MS DOS, WIndows, Linux Mac OS).
KIMPAPER is written at the time the Micro-KIM appeared. CLI utility. Supports Binary to/from Papertape. Still runs fine on all platforms supported by Freepascal (Windows, MS DOS, Linux etc) after a recompilation, source available.
ConvertHexFormat is a more recent GUI utilitilty with many more 8 bit hex formats as input and output.
There were some bugs of course in older versions. V2 added the ability for multipart hex formats, records having a non-consecutive load address. That seems to wok fine since V2.1
In 2.2 a bug in MOS Papertape format for bigger files is fixed, the end-of-file record (record type 00, total line count) had a bug in the checksum calculation. KIMPAPER is and was correct in the calculation.
But in ConvertHexFormat it was wrong (as it still is in the well known srec utility in the Unix world!).
Programs to manipulate the binary and hex formatted files of interest for SBC owners. Intel hex, MOS papertape, Motorola S-record, binary, hex conversion fort eh 8 bit world.
Runs on Windows, Linux, Mac due to Lazarus and Freepascal. Source included.
Demonstrates his design for a cassette interface for the Micro-KIM single board computer from Briel Computers (a replica of the 1970’s KIM-1 SBC). The original KIM-1 has a built-in cassette interface, but the Micro-KIM replica does not, so I designed and built his own. The design uses a single PIC micro-controller, is very reliable, supports all HyperTAPE speeds, and has the ability to save and play back recorded data into the KIM-1.
