Not anything of note to contribute, but will note that my PAS16 did come with a copy of "Out of This World". It always felt like it was a powerful piece of hardware with no real drivers or software to support it, back in the day. It will be cool if you unlock its mysteries. 30 years...

Amazing work!

It's a great article. But... My main quibble and it's pretty much a nitpick is that it sort of implies that an XGecu programmer is required for the process. On the other hand, the instructions are for someone using an XGecu. But the same procedure can be done with other programmers...

Forgot to mention, the S900 and J700 motherboards have identical form factors (they're the same board, but populated differently). The desktop case of the J700 and the tower case of the S900 are actually the same model of case from Palo Alto Products, the ATCX Convertible. The drive cage is...

Power Computing made its Catalyst clones* with a CPU slot which is identical to the Apple PowerSurge (X500/X600) CPU slot, except... There's one signal missing on the cards. I can't remember which one. I'd have to dig through email from the early 2000s to find it. Anyway, CPU cards from...

Very cool. Did they ever use this newer Valkyrie design in any machines? Unfortunately, it doesn't seem to do a contrast/compare with the original Valkyrie, so impossible to know how different it is. I think I have a couple thousand of those SGRAM chips in the attic...

That's the article I wrote way back when. By today's standards, way too much detail on the soldering and probably some of the (soldering) details are bad advice. But it is more than 25 years old, so... But there was also discussion in the forum regarding specific cards and firmware versions...

Because these are DRAMs, they interleave the addresses. So adding one address line would add two address bits to the address space. So, if a tenth address bit is available, one could address 1M X 16 (these are 256K X 16) chips. Finding 16 bit wide memory chips is not easy. Alternatively...

They're great. They have weird sockets like the ROM/cache sockets for many old world PCI Macs (x500, 6400, 6500, X100 PDS, G3 Perch). Oh, also a large stash of the 64 pin SIMM sockets. Quest is also great. They actually have stock of the X500/X600 CPU sockets in both through hole and SM...

Whether the Bandit is "seen" at F2000000 or F4000000 seems to be determined by how pins 186 and 187 on the Bandit are biased. In other words, the Bandit's address changes as the bias on those pins is changed. I think. Could be wildly wrong.... Because the PowerSurge architecture was...

I think that Phoenix Connectors also has those connectors. At least, I remember sourcing some for adapting ATX PS to the Umax S900. I'm not certain I got htem from Phoenix.

Did you see the work where the HD20 (floppy interface) was analyzed and I can't remember the result -- some kind of peripheral was created? Or is that the BMOW reference. Too many years...

Unsolicited, but my experience with UTSource is that many (most?) of their listed prices on parts are a fantasy. Request an actual quote on all parts you wish to buy and do not assume that because they listed a price and quantity on their website that they actually have any.

I may not have been reading the 2.1 spec, but what I remember is 4 PCI slots (interchangeable devices) or 10 fixed devices for signal integrity. The Apple Network Server has a mix of slots and fixed devices (2 & 4 respectively) on the bus with six devices.

This probably isn't helpful for the effort at hand, but.... The PCI Device Numbers (F, E, D) are which PCI Address line is tied to the IDSEL pin on each PCI slot. Presumably, it could be reordered by changing which address line is tied to the IDSEL for each slot. However, that would mess up...

Software and flash chip are larger on the PowerDomain than on the PC version of the card. The PC firmware won't fit. It's been more than 20 years, so memory and all that. I remember there was a version that seemed to work in the smaller flash chip, and I can't remember if it actually did...

The G4 Mac Minis came with a 7447a processor and an ATI Radeon 9200 graphics chip. Is this adaptation of 8.6 likely to work on the G4 Mini?

Yes. I had to find my old posting because I couldn't remember: https://tinkerdifferent.com/threads/se-30-reloaded-group-buy.2337/post-22017 They were suggested by someone in my rocketry club. The phosphoric acid solution from Rustoleum is Rustoleum Rust Dissolver -- or that was the product...

What metal is the SE/30 shield? IF it is iron based, then a wash of phosphoric acid is a good choice. I've bought this treatment under various covers over the years, but I think the most recent was a Rustoleum product. Regardless of who is packaging it, it is a thin, green colored liquid...

We've also seen a few users where the SCSI connector (DB25) is just so old that it's dirty/oxidized. A good contact cleaner spraying might be a good idea. Maybe DeOxit?
