This is the interface which connects the S88 circuits with the parallel (lpt) port on the first computer. The serial (com1) port goes to the booster, on my layout a MRC with 8 amps of current. |

Here a small difference with the S88, a row of resistors and capacitors. This is to place all inputs on plus to prevent interference. When a ground signal is connected to the input it is detected as "on". |
