Just wondering, but is 55 ohms actually a problem? That's only going to be a few 10s of mA, which might just be leakage currents. It doesn't sound like a metal-metal short. Anyone know what would be an expected value would be on this board? I've got a vague memory of measuring resistances on a …

you could try underclocking the card, both core and ram all the way down Downloaded ATI Tray Tools, underclocked to the lowest value, but nothing changed. Even run the benchmark for artifact but shows nothing. that leaves -gpu chip failed internally -radeons keep framebuffer in fixed memory …

Ahahahah! Well, this turned in to one of those projects of completely irrational stubbornness. There now follows a suitably long screed, the short version of which is that it's possible, with likely way too much effort, to use the reasonably available SF-C93 read head in the CR562b drive, which may …

Any chance of trying some other OS? It might be possible to boot linux from a live CD. If the missing red value is still there then it's probably a weird hardware issue (some sort of internal palette mapping?).

Does refresh rate come in to it as well? 1280*1024 is 1.3M pixels. Allow a factor of say 1.4 for blank times for horizontal and vertical flyback, so 1.8M. I think that with a clock of 110MHz that gives around 60Hz max, without any worries about colour depth and memory data rates? And maybe high …

It's been a while, but I've just given up on trying to repair some battery damage on a 110CT that it turns out had eaten ~5 legs of the CPU, debris from which has gone under the CPU. I'd need to remove the CPU to clean it up and since I've already had to replace several corroded pads that lifted off …

I don't think there's any harm in getting clk and data the wrong way around, so you could just try it one way and if it doesn't work try it the other way.

Yeah, I think Creative used the MKE bus (Matsushita and Panasonic I think), and I don't recognize that Mitsumi drive as one of the few MKE drives.

Looks like the usual 'T' arrangement. Top row is units, middle is tens and bottom is hundreds. You can see the letters A-G on the units header pins which correspond to the bars on the 7-seg digits: a f b g e c d Jumper from the center pin to either 1,2 or 3 to make the bar come on in low speed, high …

They're normally arranged as a series of 'T' shapes. For each bar of the 7-seg there's one jumper going from the centre of the 'T' to either the left, right or middle branch. Right/Left makes the segment light up when either High or Low, middle makes it always light up, remove the jumper makes it …
