Dude, it's amazing. That was my biggest doubt. So, 1292 system processor has a clock of 887 KHz and the video processor 2636 has a clock of 3.54 MHz. Now every make sense. Here in Brazil we never had access to these video games which makes everyone here very curious. Thank you for your help!

Many articles see them as the same system, but in my research they are similar systems. And this is because Interton and Radofin designed them at the same time with the help of Philips and, therefore, they are so similar. As we say here in Brazil: Children of the same mother, but of different parents.

Hi Carlsson. I read this topic, but I still had doubts about the issue of processors and memory. Another thing, the VC4000 system is not a clone of 1292, right? They are, so to speak, cousins, as the project appears to have passed through the sieve of Philips.

Yes, that makes sense. The 2650N has a maximum clock speed of 1.25 MHz. Signetics 2636, as I understand it, is a kind of video processor and is clocked at 3.58 MHz. It would make sense for the crystal to be 8,867 MHz.

Hi everyone. Guys, I'm researching for my book and I ran into this Radofin 1292 system. He is a very obscure video game system and would like to know if anyone has more detailed information about this system. First, I can't find the correct processor clock details. Everyone says that the Signetics 2650A-1 runs at 4.43 MHz, which is impossible since, because the specifications of this processor indicate that it reaches a maximum clock of 2 MHz. Another point is the amount of memory. Everybody all speak in 32. But, 32 Kilo bits or 32 Kilo Bytes? Most likely, by the time and the cost of memory at 70's, it would be 32 Kilo bits which would give about 4 Kilo Bytes. I am really grateful if someone has the right information. Thanks!
