Owner(s): Ray Kingsley

Kingsley was prolific in documenting how to program in machine language and produced several tools for programmers.


Ray Kingsley’s fixes to the Timex EXROM, available as a 2764 EPROM.
TS 2068
Adds interactive assembler to the disassembler and debugger in Hot Z. Line-by-line assembler checks syntax as you enter Z80 mnemonics and assembles directly to memory. Multiple commands to support program development. 16-64K.
TS 1000
Disassembler/assembler with data displays, ROM floating-point code display, four letter names for commonly used addresses (built-in and user-defined) and more. Features hex code input, two breakpoints, single-step with register, flag, and stack display, LOAD ZX/TS tapes,and a powerful on-the-fly assembler with delete and insert code commands. Saves and loads byte files, prints to the TS2040,
Downloadable TS 2068
Debugging tool that quickly pinpoints BASIC programming errors. Provides line-at-a-time execution of programs and allows for checking the display and the values of program variables for unexpected results. Other modes allow breakpoints to be set by line number for quick testing of long programs, by the number of passes for testing loops, or by limits
TS 1000
Display manager and data filing program in machine code. Provides a full screen editor for a direct keyboard-to- screen link with full editing and plotting features. Filing and display facilities permit page-flip animation or horizontal or vertical scrolling through windows. Stores up to 99 screens in 64K.
TS 1000
BASIC utilities that enhance programming power. MERGE programs from your own library of tested subroutines to build new programs quickly. RENUM provides neat listings, includes numbered GOTOs and GOSUBs, and flags those with expressions. COPY and DELETE blocks of lines for quick restructuring. VERIFY the contents of your tape against memory and eliminate losses to
