Old NEC multisync II and Old apple monitors will work as well. Check old multisync monitors to see if it works at 15.75 khz. |

I got one OLD nec multisync 5FG it had RGB connectors in the back... but doesn'T seem to work with it ļI get double image.... I hacked it with ''home made wires..'' to connect it to the back... Also do i need a AC line filter because when i tested it I plugged the AC to arcade power supply did some wiring for a speaker. & the rest was all on jamma & connected to PSU aswell. Is that ok? or it's dangerous? |
| BobA:
Nec 5fg only goes down to 27 Khz according to its spec. You cannot get it down to cga freq. A double picture is expected on a monitor that cannot sync low enough. An ac line filter is recommended but if you have a power bar with a real supressor you can live without it. |
| hayabusa_fmw:
by supressor = surge protector?? because im using a typical power bar... it's more or less to test a board 1 hr , or 30 mins , or even less.. i will now hunt a commodore monitor Is it hard to connect it to the monitor? do i need to hack wires into it? let me know never had or seen one upclose. |
| Angry_Radish:
yeah, you have to hack the wires to build a cable. Not too hard though, I'll see if I can find the diagram I used... **edit** Here it is: ----------- Pin out (looking into connector from the outside) \1 2 3 4 5/ \6 7 8 9/ ------- 1 Ground 2 Ground 3 Red 4 Green 5 Blue 6 Intensity 7 N/C 8 Horizontal sync 9 Vertical sync You shouldn't need to connect pin 6 (or 7). If the game has combined h/vsync (ie a Csync like all JAMMA boards) then connect it to pin 8 (HSYNC) and leave pin 9 unconnected. |
