I've finally got my WGS 8150 running pretty well. I'm kind of surprised this old 80MHz machine will run Quake. I mean, it's not silky-smooth, but it runs. I figured it run at -12FPS or something suitably horrendous. I inherited it from the company I work for. They were dumping their old stuff, and me being the restorer that I am, I grabbed up all their old Mac stuff. Fortunately, they were only all-too pleased to be rid of it. This machine came with 208MB of RAM (not too shaby), the Apple PDS display card (which seems to be dead-stick), and a Radius PrecisionColor Pro 24X nubus card. I also got two monitors out of it, an old 17" Apple Multiple Scan and a 21" Multiple Scan. I basically have two questions: 1). I've been in this business a long time, and I remember the Radius equipment. It was nice stuff, priced in the stratospheric, and chock-full of features and abilities. I don't remember, though, the various cards and their versions. As far as I know, I can't really do better for a video adapter than what is already in the machine. Unless I find a Radius Thunder IV. Did Radius make the Thunder with a nubus interface? 2). I'm really thinking the Apple PDS display adapter is dead. But I can't remember if the early PowerMacs needed a card or a loopback/terminator adapter in the slot in order to run. Does anyone remember if the PowerPC 8100's needed a card in the PDS slot? |

Here is the link to a guide to nubus video cards at low end mac: http://lowendmac.com/video/index.html It looks to be pretty comprehensive. Quote from: "breetie"
I have a 7100. There is a pds display card for these machines. If the 8100 is the same, it just pops in. Also, if you look on ebay, you wshould be able to pick up a Sonnet accelerator. If you want to use pds video, you need the pasthrough cable also. The pds video is much faster than the nubus cards but does not support as large a display. You can also get a larger SCSI drive at AfterTheMac.com. I put a 50 Gb in the 7100. I think they are a conversion of some other type, but it works fine.

Quote from: "Lichen Software" --Here is the link to a guide to nubus video cards at low end mac: Ahh, yes, I did see this, but I miss the information about the Thunder IV. Quote from: "breetie" --I have a 7100. There is a pds display card for these machines. If the 8100 is the same, it just pops in. I guess I wasn't exactly clear. What I meant to say, was, that I want to remove the Apple PDS video adapter (as it seems to be dead), and at some later time, yes, install a PDS processor upgrade card. I was just not sure if these machines will boot without a PDS card in the slot.

I think the answer to your question is 'no, you don't need teh PDS card.' The 8100 I've got here has a Sonnet G3 card in the PDS slot. You can get the Sonnet video adaptor for the G3 card which 'moves' the PDS video card to one of the Nubus slots. There appears to be something wrong with my video adaptor (it stops the machine booting) so I've removed it. I'm using the built-in on-board video output, which requires that annoying cable adaptor to get an ADC connection.
