Re: Mame Laserdisc files

Maybe the single huge 7z archive was split to smaller files to facilitate upload? If you use a tool like HJSPLIT and chose the join function it will combine all of them back to a single 7z file so you can extract it properly
Worth a shot!

Re: PVM 14N6E With Bad Deflection

there is also the possibility the tube is too worked out, it's not that uncommon that an old pvm/bvm has thousands and thousands of hours of working time...

Re: PVM 14N6E With Bad Deflection

I had vertical linearity issues with my PVM - I replaced all caps on main chassis from 100uf and upwards (it was just WAY TOO MANY to replace everything :lol: ) and this fixes my issue. The main blame was the big uf caps, from 1000uf and upwards. I did not touch the psu board in mine... The focus po...

Re: What could cause this h.linearity issue?!

Just an update to bring closure to the issue - with the help of online friends the issue was found : it is capacitor C521 that is a S Correction one in 15k mode. Original is a 470nf/200v one - replacing it with a 2.2uF capacitor the monitor's 15k h.linearity improves and now it's tolerable. Not perf...

What could cause this h.linearity issue?!

Hiya! I have a 14" 15/31k dualsync monitor, when pin15 on vga connector is high then the monitor switches to 15k mode. But I have this annoying linearity issue - right side is compressed: http://i.imgur.com/M0WfG46.png in VGA mode it's OK - you can't expand it to full screen , this is a 640x480 max ...

Re: WTB Makaimura

nope, that's a boot

original looks like this: https://www.ebay.com/itm/333162474085
that black daughterboard is the protected cpu one, it could be different but you can tell an original from the rest of the board
also notice the pattern on the top layer of the pcb - you cannot make out the tracks .

Re: J-pac for fightcade.

hehe looking good!
but try to get a better PSU IMHO , a 420~550W is more than enough - never cheap out on the psu. I used a Seasonic 420W one.
and ofcourse you can mount all like arcade boards - or use a random old pc case (maybe just the frame?) to mount all and put it in the cab

Re: J-pac for fightcade.

OK , ATI HD6000 is the series - so it means something like HD6450, HD6670, HD6970 and models in between all are good. (technically HD5000+ works but 6000 series is just more trouble-free) You need to keep in mind 2 things: - you need a VGA port or a DVI-I connector that can be turned to analog vga w...

Re: J-pac for fightcade.

You don't necessarily need an arcade-vga nowdays, you can do more with CRTEmuDriver and some ATI HD6000+ vga . Then you pair it with GroovyMAME and you get a really really awesome setup. I was about to link you the guide on how to install crtemudriver but the pages are offline atm, instead here is t...

Re: Amiga RGB Jail Bars

I have been using amigas many many years with scart/rgb connections, they are not known for jailbars.
I am placing my bet it's your lcd tv that does that, did you try another one? It would worth to build the "Experimental cable design for some troublesome LCD TVs" one instead.
