| 10 | This repository will contain supporting tools (e.g. the front-panel simulator) | |
| 11 | and maybe, at some point, binary memory images, and text files containing | |
| 12 | disassembled machine code that was entered. | |
| 10 | This repository contains the supporting tools, written in BASIC: | |
| 11 | ||
| 12 | * `binloader`, the first version of the simulated bit-entering facility, | |
| 13 | used in the warm-up | |
| 14 | * `frontpanel`, the improved version of the front-panel simulator, | |
| 15 | used to enter SITU-MON | |
| 16 | ||
| 17 | BASIC sources for these are in `src`; the tokenized PRG files are in `bin`. | |
| 18 | ||
| 19 | This repository might, at some point, also contain binary memory images, and | |
| 20 | text files containing disassembled machine code that was entered. |
