Scanlines with X68000 on Vga CRT !

[gypsie]

Hello everybody !

Last night i ve tested something interesting : to plug a Slg3000 on my X68000 compact.

What is slg3000 ? : A scanlines generator (like a 15 khz monitor)

So now i ve beautiful scanlines on my Vga CRT ( you can adjust scanlines density with the side plot).

Very happy to find this...

 Hy Gypsie !

This looks perfect for the SEGA Dreamcast. Does it support all three X68000 modes (15kHz, 24kHz, 31kHz) ?

Keep the scene alive !

If i'm not mistaken, SLG adds scan lines to a VGA signal. And that's it.
As VGA is 31khz..

X68000 output looks more like CGA (15/24/31)
You'd need a converter like GBS-8220 (has anyone tested it especially frequency switch?) or XPC-4 before adding SLG.

Wonder how the GBS-8220/SLG couple would behave on a x68000.
GBS is dirt cheap compared to XPC-4.

It's working only for 31 khz mode . The best games are 31 khz compatible (final fight,Ghouls and ghost,strider etc...), so slg is very good.

not bad you can get a Mini SLG from craftymech for a fraction of the cost.

as long as you run 640x480 or 1024x768 resolutions

Yup Ope. Mine just arrived today and it works well with the XPC-4. Just twiddling my thumbs now till my x68k arrives later this week.

Nice and compact and the price is right.

This thread reminded me that I wanted to test my Hanzo Dreamcast VGA/Scanliner box in VGA mode with the X68k. I swapped out the input cable on the Hanzo for a VGA input and once I remembered that it only supports 640x480 and 1024x768, it worked like a champ. Really brings the picture on an LCD back to what it should look like.

I tested it with both 15 and 31khz inputs into an XPC-4 and it handled them just fine. Mode switches didn't cause any issues either, but I didn't suspect they would.
