Fortunately, a real calculator convinced him that his app had a bug (a RAD to DEG conversion programming error) -- he immediately found a better calculator app. Bob

Raspberry Pi

by healyzh＠aracnet.com

The talk about the Acorn and RISC OS reminds me that I've been interested in one of these, primarily to run RISC OS. What is the recommended version, price, and place to get a Raspberry Pi from? I assume I want a "2.0 Model B 512Mb"? I've found a seller on eBay with this and they include a case for $57. Zane -- | Zane H.

I ran my first version of AutoCAD (2.08, Release 5) on an XT clone with a CGA card. Later, I was able to afford a Techmar Graphics Master. I could run that at 708 by 708 monochrome on the same XT clone. I still have the software, but unfortunately no longer have the Techmar card. I have also run AutoCAD 2.14 (Release 6) on an HP 200LX palmtop, which is basically CGA. It can be done, but the limited resolution does hamper what you can do. I also have a copy of AutoCAD 1.4 (Release 4, 1983) that was customized by John Walker to run on an Otrona Attache 8:16 for an archaeologist colleague at the University of Chicago. The Otrona has a strange software emulation of CGA! Bob

Which PDP-8, PDP-11, Etc., Components Require Protection from High Humidity?

by bobvines00＠gmail.com

I've been storing my PDP-8s, PDP-11s, disk drive units, floppies, etc., in my garage at about 45% relative humidity in an attempt to prevent corrosion/deterioration. Finances are about to force me to turn off my dehumidifier out there and I can't bring the *complete* machines into the house. Which components, modules, or other related items should I be most concerned about protecting from high humidity? Which should I move into my house? Magnetic core modules? Disk packs? Floppies? Etc.? Any recommendations? Thanks, Bob

Interesting proposition. I'll wager it's not very straitforward. Numerous graphics cards had drivers for say Autocad and whatnot. But that's entirely different from the startup code needed to set up initial register values and whatever on the cards chips. It seems what you're saying is the pc will startup w/o video (usually returns an error, but you can use a pc w/a terminal off the rs232 port, just don't ask me the particulars). Then initialize the video card as dos is starting.

You can certainly try jumping to the code location >in DEBUG or the like. Which lead me to ask what a video device driver is/does. Presumably when you type Mode co,80 iirc, or screen 1 in basic, you're assigning different values to ports ie fiddling with say the 6845's registers, thereby creating another screen on the fly. Unless I'm wrong. But if not, isn't that kind of what a dd does? There's bound to be more then that going on. But code is code, regardless of what stage of the game you're in, start up, boot up, os fully installed. The os only has as much control as you allow it. You communicate with dos, but s/w at least can manipulate the h/w. Which is why s/w has too much power under dos. When dos transfers control to a bunch of code, it's boss. > >- Dave > >

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/

Got one too :) But the "box" doesn't work, too well anyway. I just figured I could hit ya up for a rom image if necessary. ------------------------------ On Thu, Feb 28, 2013 2:04 PM PST Dave Land wrote: >On 2/28/13 12:43 PM, Chris Tofu wrote: >> >> Hey Dave, is your Xerox fully functional? >> >> >Chris, > >Yes, it works very well as a matter of fact. :) ..and before you ask, >that's the one I'll probably hang onto for a while, heh heh! > >D- > >-- >Dave Land >Land Computer Service > >Check out my site at http://www.landcomp.net

Raspberry Pi

by barythrin＠gmail.com

Its not going to be rpi specific but it will be at risk for any standard exploit for services it hosts. You could pwn it via apache, dns, mail server, etc but again its mostly app vulnerabilities and no real blame to the product itself. For protection it shouldn't have any problem running simple iptables (firewall rules), clamav (on demand virus scanner) if desired or I suppose even snort or other ids/ips although thatd certainly take away from the limited resources. Either way it should have all the charm of the ported OS.
