Here is a great example of why the keyboards and terminals are getting separated https://www.ebay.com/itm/IBM-3101-beam-spring-keyboard-purchased-new-in-198… Note the price $2000 so far. How could one blame the seller. I wonder if this is the terminal I sold to a buyer in California years ago when I sold my Series/1 computer. All he wanted was the terminal, I donated the rest to what was the MARCH museum. At the time I remember having a few words with the buyer who would not also take the Series/1 system (2 racks) or the manuals. There is a naked terminal up for grabs if you're out his way. Bill

Have to concur with this. Even the "minimalist" (i.e. non-GNOME/KDE) *nix "desktop environment" projects these days are getting so bloated that I've given up bothering with them and set up an X environment one component at a time. Currently running Window Maker with SpaceFM and ROXTerm; getting it all properly set up and tweaked to my liking took some doing, but the payoff was well worth it. Now if I could only excise the GTK3 blight entirely, I'd really be set.

There was a recent discussion about code density (I forget whether here, or on TUHS), and someone mentioned this paper: http://web.eece.maine.edu/~vweaver/papers/iccd09/iccd09_density.pdf which shows that for a combo of benchmarks, the PDP-11 had the densest code out of all the ones they looked at. (They didn't look at the PDP-8, but I suspect that since it's a single-address design, it's almost ceertainly not as dense.) The PDP-11 dates back to the days of core (it went through several generations before DRAM arrived - e.g. the -11/70 originally shipped with core), and given core prices, minimizing code size was pretty important - hence the results above. So if you want to get the most bang out of 16K buck... Not the simplest machine to implement, mind - the -8 is a lot simpler. Which axis is the most important to you? Noel

Not really vintage computing, but just in case it's of interest to anyone..

There's also the Afterstep/Window Maker crowd, open-source reimplementations of the NEXTSTEP desktop environment, which predates even Windows 3.x. Win95 was certainly very influential in the design and refinement of many other desktop environments going forward, but it's not the be-all and end-all of anything. >> Liam Proven wrote: > > How many graphical Unix desktops are sold or distributed in the world > today that are not Linux?

But this is kind of a questionable standard to begin with, because the whole point in the Freenix world is choice. No distributions offer those as default options during the install process, but all of them (aside from CDE, which only just went open-source a couple years ago and is still in the process of being cleaned up and forward-ported to modern *nixen) are available in the repositories for most major distributions, and all of them are still actively updated. > BeOS used the Windows model. Kinda-sorta-not-really. BeOS (like just about everything post-1995) takes cues from Win95, but its roots are in classic Mac OS and it definitely hews closer to that in most respects, despite the absence of a global menu bar. > Outside of Apple, I think it is fair to say that no new OS or desktop > environment since 1995 has used anything other than the Win95 model. Haiku says hi.

This "aside from the things that don't match up with my argument, my argument is flawless!" line of reasoning is novel.

What's the word length on that machine, BTW? I ask because it would be hard to pull that trick on most short-word-length machines, there just isn't a spare bit or two in the instruction to add that.

It was a 16K RAM card that was equivalent to the Apple "Language Card", which allowed replacing the 12K of ROM of the Apple II and II+ with 16K of RAM, of which 4K had two banks. Although it was useful with the Softcard, it wasn't in any way specific to it. All models of the Softcard could output 80 x 24 text, not only through third-party cards, but Apple's own 64K RAM and 80 x 24 video combo card, Which was only available for the IIe. I stand by my assertion that the Softcard did not in any way provide 80x24 text. It could use the capability if it was separately provided.
