A brief buyers guide to retrocomputing terminology

Untested   -  Broken
Power light comes on not tested further - Mostly broken
No monitor couldn't test output - display broken
Would suit a collector - useless to anyone
Retro - overpriced
Rare - overpriced
Extremely Rare - Very overpriced
Unusual - routine
Not many people have one of these - nobody wants one either
No disks - disk drive broken
Found in my attic - professional dealer
Cosmetic damage - broken
Cables missing - I kept them, they are hard to find, good luck finding replacements
May be a prototype - not a prototype
First revision PCB - buggier than all the others on sale
Slightly yellowed - owner smoked like a chimney
Some screws missing  - held together with sellotape
Batteries need replacing - batteries have exploded all over the PCB and case
I don't know what this is - yes I do and it's junk
Selling my personal collection due to lack of space - professional dealer
Ditto, house move - professional dealer
Some scratches - lost a ten year long war with the cat
Enquire for postage costs - preferably after you bought it ..
A few non-original parts - built out of several broken ones and components from Maplin
Needs a clean - I tried for weeks but couldn't get the yellowing off

Fed up of SystemD ?
Kdbus the final straw ?
Linux community too large and noisy ?
Yearn for the good old days when you knew every contributor by name and the source code fitted on a single floppy disc ?

I am pleased to announce the initial (very initial) code drop of the Fuzix OS. The goal of Fuzix is to provide a reasonably complete Systen 5 Unix experience without all the bloat. At this point in time the kernel needs about 40K, plus memory for user space.

The Initially supported processor architecture is the Zilog Z80. The code uses no "naughty" instructions so should run correctly on clones and variants, as well as on things like the T80 FPGA core. The core code has been built for 6809 and 6502 as a sanity test but more work would be needed to bring up an actual platform. In theory if it's got 8bits and banked RAM you can probably run Fuzix OS on it.

At this point there is no 8086 port. It's certainly doable for a PC/XT or PC/AT style box but needs a usable open source ANSI C for 8086.. I've done some initial work on pcc ( but could do with help on bringing that up further as I've not had time to make much progress on it.

So why Fuzix ?

- There are various other "modern" OS for Z80 systems but they are not CPU portable, and except for CP/M mostly non-free or depending upon non-free tools. In time they will become a liability not an aid to playing with old systems

- UZI is neat but constrained by limits in the tools and unbanked memory configuration

- UZI180 is neater but still lacks some basic features

- All the existing UZI variants are forks, and generally incompatible. That's not a long term sustainable way to maintain retro systems.

But in truth the main reason is simpler

- Because it's fun.... and it's halloween which as an ex Red Hatter is kind of the right day for a release

Hello everybody out there using Linux -

I'm doing a (free) operating system (just a hobby, even if it's big and professional) for 486+ AT clones and just about anything else out there under the sun. This has been brewing since april 1991, and is still not ready. I'd like any feedback on things people like/dislike in Linux 3.11-rc7.

I originally ported bash(1.08) and gcc(1.40), but others have taken over user space and things still seem to work. This implies that I'll get the final 3.11 release within a week, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)
