Nope, not an issue at all for the Indigo2. Forget all of that.

A Toshiba XM-5401 with the normal firmware is already compatible.

Spectre and Meltdown do not affect the Mill. http://millcomputing.com/blog/wp-content/uploads/2018/01/Spectre.03.pdf The paper is actually not so sanguine. They found that to prevent data being exposed by Spectre code, they had to change the rules used by the binary specializer. They also changed (...

Re: Installing Firefox on Octane. Lots of dependencies.

To be fair, 2000s-era GNU extensions aren't "fundamental" to Unix in any way, but familiarity is useful for administrative tasks. The alphabet soup of command options gets more bewildering each year. .tbz is just a shorthand for .tar.bz2, especially since files may get transferred through ...

Re: High Impact or Max Impact?

It depends on how you want to use the machine: if you want to use it for (standard definition) video capture or output, and also transfer captured files over the network, then it would be helpful to have 2 spare slots, one for Impact Video and the other for a 100Mbit ethernet card (either the G160 o...

Re: A Guide on Your Options for non-x86 Computers (2017)

That's actually a very shrewd point. As long as "security" is a premium commodity, it is easily monitored and subverted—look at the history of Crypto AG. Better to remain completely obscure, or blend in with the masses. This also applies to things like the "Do Not Track" HTTP hea...

Re: WTB: Cherokee PSU

It appears that there are a string of four TO-220 (or similar) three-leg components on that heatsink. A dentist's mirror would help in seeing what's printed on them.

The direct successor to BMRT was called Entropy, it was only briefly available before a copyright conflict (with Pixar? someone remembers) made it unavailable.

no dollar sign in "setenv DELIGHT /usr/local/3delight-5.0.11/IRIX-mips4" (if you are using tcsh)

Re: Maintaining Hardware / fesability of keeping hardware running

You need fairly high energy X-rays to see copper traces clearly (30kV or above; 80kV even better). Copper atoms cross section is a lot more than epoxy or glass. The advantage is that you can image very small traces or bond wires: down to a hundredth of a mm should be possible with the right equipment.

Re: IPX and EDO memory

There were simms that were only 33 bits wide (1 parity bit per word), instead of the normal 36 bits wide (1 parity bit per byte). That saved on dram chips, because the chips for parity needed to be x1 (less dense). A 36 bit simm needed 4 parity chips per bank, since it had 4 byte select lines. A 33 ...

Anti-reflective (AR) coating, or combined anti-reflective and anti-static (ARAS) coating. They are not that easy to repair or remove. In essence they place a thin layer of silica over a ceramic layer with controlled particle size. The silica is hard and chemical-resistant enough that you can use gla...
