Amstrad CPC 464
I recently puchased an Amstrad CPC 464 from ebay that was only tested to the extent that it had a power light. Once I obtained the proper 5vdc power supply and SCART cable I was able to test the system, and wouldn’t you know it?! No Video out. The Z80 has good voltage and ground, the clock signal is traversing IC125 and present on the 40007 chip and Z80. To add to the confusion, the board is not the same as most schematics that I was able to find on the internet. The specific board I have is covered in an addendum with different components than the first board. At this point I am leaning towards an issue is with the Gate Array. More to come on that.
