So why didn't you use a terminal? You can run a video card and a terminal simultaneously, no?

Qudos MINICHIP / Quickchip ECAD and Ferranti ULA docs

by classiccmp＠philpem.me.uk

In my long-running tradition of obscure requests... Does anyone know if a copy of the Qudos Ltd "MINICHIP" gate array design tool still exists anywhere? This was a CAD tool designed for the BBC Micro (with 6502 Second Processor) which allowed the machine to be used for the design of Ferranti ULA gate arrays. There was also a similar tool called "Quickchip" for the Acorn Archimedes ("A440 only" according to page 22 of this: http://acorn.chriswhy.co.uk/docs/Acorn/Brochures/Acorn_APP155_HardwareExpan… ) There's some mention of MINICHIP here: http://www.chilton-computing.org.uk/inf/literature/newsletters//ecn01-20/p0… http://books.google.co.uk/books?id=GzPpAAAAIAAJ&lpg=PA85&ots=sR_gUYkMii&dq=… I'm also interested in a copy of any documentation on Ferranti ULAs - databooks, details on the logic cells (specifically the ULA9C series but ULA5C may also be useful), design software (or documentation thereof) and so on. Examples: Qudos Ltd. - Qudos Logic Array Design Software Manual QED2 (pub. 1986) Ferranti - Ferranti ULA Design Manual A/F002 (pub. 1981) Guessing what I'm trying to do is left as an exercise to the reader... but it involves photos of the Tube ULA layer masks and a copy of Degate... :P Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

The 75mhz Arm made the clearing of the stack tolerable (less then a second, 3-4 on the 49g. Zounds). You got to love something. You can't fix everything in this day and age. I'm told the TI-nspire CX CAS is more toy then anything. You gotta love something though. My 49g's have fallen on hard times. Can't figure out why my old TI86 doesn't work, I used it 3 times. Need a replacement. Need one bad...

Bit late, but I'm totally up for... let's say three... Omnibus-USB interfaces. Let me know details when they're fixed - price, ordering etc. Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

The chances of any targeted virus to an arm at this point is pretty remote, though I'm sure there are linux exploits that may be applies. C: we were specifically discussing performance. People seem to have an inordinate attachment to this thing. And do I have to say again I'm not altogether panning it. But to state there's no concerns about virus' on a unit that's being touted as general purpose computer is insane. The performance benefits obviously have everything to do with what it's running (commonly running?). You could install an inefficient pig on rpi just like anything else. I'm not confusing anything. There's many reasons why things go slow and things go fast.

HPUX Enterprise Operating Environment

by xmechanic＠landcomp.net

Don't know if anyone is interested, but I have a complete boxed set of HPUX 11i Ver. 1 Enterprise Operating Environment complete with Gold Pack updates, and Bonus Pack Software. Covers most all of the PA-RISC machines capable of supporting HPUX 11i (9000 series servers, workstations, etc.) I had bought it several years ago for a J6750 workstation that I eventually changed over to Linux. You can see the details here... http://www.landcomp.net/index.php/2012-11-28-23-34-35/15-computer-related/7… -- Dave Land Land Computer Service Check out my site at http://www.landcomp.net
