Hello, everyone!!

A short time ago I got two Televideo TPC-2, I can't get the manuals and I can't expand the memory, I tried all the combinations of the switches and jumpers, I even took out a jumper that was not on the mother of the one that was expanded and does not work.

The memories are the same as those of C64 so I tried them there and they work.

In the current photo of the mother there are not all the memories, but I only have them that I was testing conventions for a few hours.

Did you ever get this working?
Yes, it is working, I miscalculated the amount of memory, it can only have 256k I have some errors from time to time but I am waiting for new ICs to replace the bad memories, it is a relic and it was assembled in my country, I am happy to have it running.
