Capacitor #3
Description
Hi,
I was looking at the original Microsol CDX-2
schematic.
https://www.msxpro.com/hardware/esquemas/cdx-2.pdf
I found some differences like replacing the obsolete 74LS16 by the 74LS06. And replacing the decoupling ceramic capacitors 47nf to 100nf. The only problem is the C1 in the original schematic is an electrolytic capacitor 47uF, but in your board I cannot see that.
I tried to find the original board photos but I could not find it. Can you check it?
