TI LOGO II error when loading cartridge

Recommended Posts

I recently picked up a complete TI LOGO II binder much to my delight since it had been easily 35 years since I had seen one of these last.

 

When I put in the cartridge and load, though, the TI gives an error to the effect of 'Please Check TI System'- leafing through the documentation it's pretty vague at the beginning but I think this ties back to it needing the 32k Memory Expansion to work.

 

Can someone confirm this is the case? It's not a game-ender for me, just something else I'm going to have to convince my wife that I *need* for my nascent collection, hehehehe.

Yep. This is the definition for Logo 2 in MAME, as I set it up after testing. See element "usage".

aha! sweet, thank you for the confirmation.

 

I saw a 32k expansion card on Arcadeshopper's webpage, so I guess I will start working on my 'budget request' from my boss. ;)

 

that would be JediMatt's 32k side car. Great unit.

 

Remember if you are using it with a speech synthesizer you will need to provide an external power source or jump power across pin 1 since the speech does not pass the power through it.
