Community,
I purchased an OSSC over the weekend and, now I’ve seen just how good 240p lx5 is, I’m looking to hook some of my arcade boards upto it.
I built my own supergun a number of years ago which uses pots on the RGB lines and pure sync through a JAMMA connector. This worked with my previous TV for many years – a blissful ignorance. It is only during research about the OSSC that I’ve found out that this is a very bad idea, and people would typically use a resistor on the sync line to reduce it down to a safe level!
Looking on the wiki I can see that AV3 using RGBS requires TTL-level sync, which as I understand it is what JAMMA puts out. I have the materials lying around to rig up a SCART to HD-15 lead. My googling has only seemed to take me so far, so I wanted to ask a few questions about this and get some definitive answers before I take any action:
Will using JAMMA sync into AV3 without a resistor damage or reduce the life of the OSSC?
If not, do people typically avoid going this route because of the absence of a LPF on AV3?
Is there a resistor that I can use on the sync line which will play nice with both AV1 and AV3?
Thanks in advance!
