# PROTOVAC UNIVERSAL COMPUTER |
|
|
|
Protovac is software for an old dumb terminal CRT screen that's used to display |
|
random info about Protospace. There's a few interactive features like sending |
|
messages to a huge marquee LED sign and performing calculations. |
|
|
|
 |
|
|
|
Here are some of its screens: |

### SD Card |
|
|
|
Format SD card, mount on your own system. |
|
|
|
``` |
|
$ cd boot/ # on SD card |

|
``` |
|
$ cd rootfs/ # on SD card |
|
$ sudo touch var/spool/cron/crontabs/pi |
|
$ sudo chmod u=rw,og= var/spool/cron/crontabs/pi |
|
$ sudo chown pi:crontab var/spool/cron/crontabs/pi |
|
``` |
