Series 74, box 5, folder 17.
1. Add WINTER-PI example programs for output to line printer and SPO.
2. Add BALGOL-INPUTMEDIA-OUTPUTMEDIA directory for eventual support of
paper tape I/O in the compiler and run-time library.
1. Revised versions of Generator and Compiler tapes, and their callout decks.
2. Object program callout deck to load and run compiled programs from their object tape.
3. Minor corrections to BAC-Assembler for object code output.
4. Implement object card output for GEN-Assembler, similar to BAC-Assembler.html
5. Corrections and compilation listings for example programs from BALGOL Reference Manual. All examples from the manual now compile.
6. Sample data deck and execution output for Example-1 program from Reference Manual. The results now show 6-7 digit agreement with results from modern Unisys MCP ("E-mode") Algol.
7. Minor changes to output formatting for E-mode and B5500 versions of the Example-1 program.
8. Manually-reformatted listing of E-mode Example-1 results to make them easier to compare with the BALGOL results.
1. Updated compiler and library sources after second proofing pass.
2. Updated Generator and Compiler object code and build decks.
3. Updated Generator and Compiler loadable object tapes.
4. Corrections to BAC-Assembler and enhancements for additional card/tape output options.
5. Minor corrections to GEN-Assembler.
6. Updates to miscellaneous utilities and example programs.
1. Implementation Paper Tape Reader devices and op codes.
2. Commit standard and inverse-format paper tape loaders for WINTER.PI program.
3. Fix positioning of Cardatron and TTY/Paper Tape Punch device windows.
1. Finish implementation of Cardatron input and output units.
2. Minor corrections to BAC-Assembler script and BALGOL-Generator transcription.
3. Apply band-select "punches" in column 1 of WINTER.PI.card assembler deck.
4. Implement striping on Console register displays to highlight the opcode (62) fields.
5. Implement List-Cards utility to read cards from CR1 and list them on LP2.
1. Initial Cardatron implementation with CardatronInput (card reader).
2. Implement default Pi demo program at address 0300.
3. Implement WINTER.PI card-load deck to boot from card reader 1 and run at address 0500.
4. Fix syntax typos in tools/BAC-Assembler.html.
