| 342 | | ROM is a bad dump, corrections are being made. |
| 342 | This is a S100 card. |
| 343 | |
| 344 | ROM is a bad dump, scanned from a pdf. It is being worked on. |
| 345 | |
| 346 | No schematic available, most of this is guesswork. |
| 347 | |
| 348 | ToDo: |
| 349 | - dips |
| 350 | - leds |
| 351 | - need schematic to find out what else is missing |
