I had some time last night so I tried changing the device ID in the ROM to 0x5964 on a card that would otherwise be 0x5960. This was the result (viewed with an NVIDIA AGP card):
As one might expect, it didn't work. My conclusion is either that 0x5960 is set in the hardware in a way I don't...
That board looks like it should only need compressed air, and maybe a soft brush. It would be wise to replace the electrolytic capacitors at this point.
The red dots are the glue used to hold surface-mount components in place during soldering and they are harmless.
@herd that's really cool, thanks! I've gotten a lot of good video card info from VOGONS. It's a great resource.
An eBay seller offered me a good price on a PCI Radeon 9200 SE. I haven't gone for it (yet). Based on the little research I've done, I expect the 9200 SE will have a device ID of...
There was a G5-compatible PCIe X1900 GT, and its ROM is on The Mac Elite. As far as I know, nobody has gotten the AGP version working. The X1300 is, in theory, 1/4 of an X1900. So as a prerequisite, if the AGP X1900 could be made to work, then maybe the X1300 PCI could be made to work. Each is a...
Thanks guys, yeah, having some fairly low-stakes fun with these old PCI cards.
I finished up jt's VisionTek card today. It got a recap, and I replaced the diodes with STTH310s, which are 1.7V forward voltage. I measured 843mV across them while the card was running, so they're definitely doing...
There are no failure-prone RIFA safety caps in the SE power supply or on its analog board. You were having some display issues before this happened, right? I suspect the flyback transformer is what failed.
The SE and SE/30 power supplies are compatible, but you may need an analog board repair...
You can get a SWIM that will work in your SE from Kero's Mac Mods in Japan for $48: https://en.infinityproducts.co.jp/product-page/super-wh-iwm-swapper-plcc44-to-dip28-swim-adapter
For an extra $16, you can also get flashed ROMs, but they're not pin-compatible, so there's a little extra work...
I had some NTD40N03s on hand, so I tried swapping them in for the NTD14N03s. As expected, no improvement. Still burning hot. Here's the reference schematic for this regulator:
The VisionTek card doesn't implement it exactly as shown above, but it shares one thing in common that I hadn't really...
The limited experimentation I've done with bus overclocking suggests that EDO modules can work at faster bus speeds (up to 60MHz) where my FPM modules do not.
I have been misunderstanding all of the TLV431-based regulators on these cards. They are not switchers at all. While it is possible to build a switching regulator with a shunt reference like the TLV431, the configuration here is a linear regulator. They find a gate voltage where the FET's RDSon...
Somewhat unexpectedly, this saga continues. @Trash80toHP_Mini asked me to convert a PCI 9250 for him, and I agreed to take a shot at it. Specifically one of these, a VisionTek with a DMS-59 connector:
The DMS-59 output is odd and was clearly chosen for its ability to fit into a low-profile...
Funny that this thread is still getting posts. The OP has not been here in over a month. In perspective, I would say that his software was a great success.
Glider up to at least version 4 is playable with music on a 68000 in b&w. It will bog down a bit when there are a multiple sprites on the screen, but it's playable.
