Looks like this uses the ISL59885? If so, it can be helpful with the Taito F3 when used with the XRGB mini and tri-sync monitors, it's what's been used in the HAS since 2016.
Yes. It uses a very similiar setup to HAS, so it
should work. Although one person here reports that it doesn't, sadly.
I will need the Martin Jones circuit add-on in order to play Taito F3 games.
This add-on would be down the road (and might never happen). The expansion option is there and I'd love to do it, but it would take at least 10 - 20 pre-orders to make it worth the time / effort. I have a bunch of other PCB designs to support that are more popular at the moment.
I might design a Martin Jones circuit add-on later if there's interest.
If you do, then could you please look to incorporate the
combined HV + Combined Sync input option?
Already done. Will be in V2.0 (and an improvement off that circuit).
Definitely interested in MJ SPG-like functionality in in SCP. In speaking with a group of local arcade enthusiasts/experts about my early results, they mentioned SCP enabling the F3 to work with the PFX is a litmus test.
F3 + PFX is such a specific requirement. While I understand the die-hards want this most, there are hundreds, if not thousands, of PCBs with and game consoles with sync timing issues that the Sync Clean Pro PCB will help solve on a regular (standard res) monitor.
It is surprising that the Sync Clean Pro V1.0 hasn't solved the Taito issue with your PFX setup, since reports are that the HAS does work with it (my design is very similar).
Can others confirm this?
@acblunden2 would you mind reporting back here the results of your tests with other PCBs and monitors? This would be very helpful
What would also help is:
1. Having someone else to test the Taito F3 with and without the Sanwa PFX to doublecheck compatibility
2. Having someone with an oscilloscope measure before and after the Sync Clean Pro is used
3. Someone sending me a Taito F3 to do these tests myself (without the Sanwa PFX).
I took a look at
the manual for the Sanwa PFX and there are some important notes on page 2:
4. Sync input is
positive. Arcade PCBs usually output "negative" (inverted) sync, as does the Sync Clean Pro V1.0
(edit: maybe the manual just means positive voltage? Since it is referencing polarity, although I've never seen or heard of negative polarity sync)
5. It has both 75ohm and TTL sync inputs (TTL uses 8 pin connector).
@acblunden2 - are you testing with the 8-pin connector?
Version 2.0 of Sync Clean Pro will have a 75ohm Sync option (customer must request when ordering, inplace of TTL)
Version 2.0 of Sync Clean Pro will have a reverse polarity sync option (via solder jumper).
I'll keep this thread updated as things progress.
