Go to "Mick and Ralphs" talk to Ralph, talk to him about the sexbot and ask about needing a holotape or anything for the sex bot, he will say he can get you one, just wait a few days.
Wait about 3 days and talk to him again and he will give it to you.
To find the sexbot, go to the "Mick and Ralphs crier" near the blue buss doors. Look right, keep going down the street twords the wall and you will see a small street to your left, go down the street twords the rubble, there is a small path in the rubble.
Note, if you have the holotape, you do NOT need the 50 science to hack the terminal.

Yeah I hacked the PC but there was no option to do anything. One of about 20 bugs I've found with this game. And my auto and quick saves are permanently stuck on a save 15 levels ago. It's a shame a patch for this game can't be discovered by following a marker on my map.
