| Posted by: nickpunt on 2020-04-10 16:08:36 After 7 years and dozens of various acquisitions, I've finally got a Micron Xceed! Pretty excited about getting it running. It came from a rusted SE/30 from eBay. I believe this is a Color 30 model.   The only damage is some rusting on the PDS connector. After some toothbrush cleaning it looks decent.  The card shows up in TattleTech (I think, below is what I see) when running in a good SE/30 and not plugged into a monitor. I've run into some trouble with video out, which may that my external monitor finally gave out, or perhaps it outputs at a resolution my DB15->VGA adapter can't handle. When plugged into video out, the main SE/30 screen shows squared edges, a sign that its moved the primary video to external monitor. Other video cards like the RasterOps Color Board 108+SE/30 I have output at fixed frequencies which this monitor can't handle. Gamba's specs table isn't clear on whether 640x480 is fixed (like at 67hz) or not. Anyone know?  Anyway, the SE/30 it came from is definitely toast. Check out this logic board:   The Xceed didn't come with the greyscale kit, so I'm now looking for that. Maybe @Bolle has some ideas, given I spotted a beautiful one on a white board he made recently 😉 | |

| Posted by: Crutch on 2020-04-10 17:00:20 I remember that eBay listing. Glad it seems to be working! | |
| Posted by: LaPorta on 2020-04-10 17:37:57 Save the RAM, and extract the chips that aren't hosed! I have no doubt that in the future there will be good boards, but with blown parts. Relatively low-mileage replacements will be of great help. As for your video issue, perhaps try a ~2000 vintage LCD with one of those NEC multi sync adapters. I have had great success with that combo working with almost anything I throw at it. Wonderful find! I hope it was a steal. | |
| Posted by: joshc on 2020-04-11 06:27:21 If you still have the SE/30 logicboard, it would be nice to see how far you can clean it up. As LaPorta has said, there will be some useful components you could salvage from it. Nice score for the Micron card 🙂 | |
| Posted by: nickpunt on 2020-04-11 13:07:36 Definitely salvaging what I can from this board! At some point my six half-working SE/30s will become three working ones 🙂 According to the Xceed Color 30 manual, it outputs 640x480 @ 67Hz, so isn't compatible with my 2001 NEC LCD unfortunately. Wish there was some 67Hz -> 60Hz adapter or reencoder out there but I've never seen one.  | |
| Posted by: joethezombie on 2020-04-11 14:35:10 Sweet! Welcome to the club. I know you've been looking for quite some time. And a very decent price to boot! | |
Posted by: Bolle on 2020-04-11 23:12:59Maybe @Bolle has some ideas, given I spotted a beautiful one on a white board he made recently 😉Sure. Eagle and gerber files for that board are available here: Making the harness is not too hard either. Pinouts for that one can be found on the old gamba pages and in the various Micron documents that are floating around the web. | |
