Hey everyone. I have everything I need to get my Topo 1 work except the transmitter controller card. Does anyone know where I would be able to buy one? Is there anything I can use as a replacement? Thanks for the help! Appreciate you!

Hey @Sjames1990!
Could you give more information about this “Topo 1” robot?
Is it maybe this one Topo (robot) - Wikipedia ?
Very old robot indeed 
Yes! That’s the one. The original Topo

Wow, that’s interesting!
Where did you find it? How did you determine that this transmitter controller card is not working? Do you have any photos?
