I have a Sega Teradrive PC connected to a Gobes GBS-8200 V4.0 converter via its DB15 VGA input, the converter VGA output then goes to a Dell PC screen (I've tried my LCD with the same results). Basically, the Sega MD side 15 Khz VGA signal displays fine through the converter (RGBS), but the IBM PC side 31 Khz VGA ouput refuses to display properly through the same input and cable, all I get is a distorted and frozen screen (RGBHV). I've tried different setting with little success, I was into thinking the GBS-8200 could handle EGA/CGA and VGA 15/24 and 31Khz input signals. Am I overlooking something? Any help is much appreciated, or if someone can point me in the right direction that helps too. Thanks in advance. Teradrive MD side>VGA output>15khz> GBS8200 input>GBS8200 VGA output GOOD = Teradrive PC side>VGA output>31 khz> GBS8200 input>GBS8200 VGA output BAD =
Hold in the "auto" button on the gbs with it all turned on.... I forget how long you have to hold it in for, so just do 5 seconds and see what happens... The "down" button is the auto button, but the gbs is pretty horrible anyway...
Hi there, I got a GBS-8200 V4.0 and with a Brazilian SNES 1chip-03 it works fine on getting RGB + sync on luma. But on my Sega MD from TEC TOY board it does not work. I tried getting the signal from csync and composite video and nothing. I tried passing the csync through a LM1881 and still nothing. I tried all the scart schemes that I found to extract the signal with the caps, the 75R and 680R on sync and still nothing. I look over a couple of threads and found out that some sega md csync signal on some board may have a problem. Can any body help??? My board is a TEC TOY P3 M.D. III C/RF with the following components: M68K CPU: Motorola MC68HC000FN8 M68K memory: Sanyo LC331632M-12 Z80 CPU: Zilog Z84C0006FEC Main ASIC: Sega 315-5660 Video Encoder: Fujitsu MB3514 Amplifier: BA10324AF
