Works fine. Same experience here. i've made copies of IRIX CDs, and I've made non-standard bootable distribution CDs. The only unusual feature is that they're an EFS filesystem rather than, say, ISO9660. But as far as a burner is concerned, an image is an image, and as far as Linux's dd command is concerned, the same is true (I've copied Apple CDs the same way, by dd'ing from the raw disk device holding the CD, to a file.). -- Pete Peter Turnbull Network Manager University of York

Humm... but this still won't work for PSX game discs right? Since they have a bad checksum, a standard burner can't write them back out, because it will correct the checksum? What I don't understand is, why can't someone write a program that will write the back check? I used to have a floppy disk copier for the Mac that did something similar. If the source disk was damaged, it would write the damaged data to the destination disk (the software was SUPPOSED to do that, it was to let you duplicate bad disks before running things like MacTools on it, in case it didn't work, you could dupe it again, and try something different) Alas, that software was for back in the "Classic Mac" era, and no longer runs (nor has any idea how to write to a CD) -c

FDC's (was Re: MITS 2SIO serial chip?)

by CLeyson＠aol.com

Try www.dialelec.com, they're UK based and specialize in obsolete silicon. No price given for the WD1773, you'll have to get a quote. They're not too expensive, I recently bought some AM2901CDC's for about 7USD each. Chris

I'm sure a Cyber 910 is a rebadged 4D/35 (or variant, depending on the Cyber suffix), very similar to an Indigo, and much smaller than a 3000. There are plenty of pictures on the web, and references in the 4D FAQ. They'll run IRIX 4 or IRIX 5. http://www.geocities.com/SiliconValley/Pines/2258/4dfaq.html -- Pete Peter Turnbull Network Manager University of York

Honkey

by DAW＠yalepress3.unipress.yale.edu

! honky has been around for a long time - my dad was a Chicago ! cop since '55 ! and even when I was little (4 or 5) I've heard him telling ! "war stories" of ! encounters with the people on his beat where they referred to ! white folks as ! "honkies". Interesting. But I'm still curious as to how it got started... ! "hood" is a newer term, but I remember hearing ofay and otay ! on episodes of ! the Little Rascals, from back in the 30's... ! ! "cracker" is a southern version of "honky", never heard it ! until I went to ! texas for basic training. ! ! How in the hell did this list get into racial slang anyway? Well, somehow we got to talking about Kwanzaa.... --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818

FDCs (was: MITS 2SIO serial chip?

From: Fred Cisin (XenoSoft) <cisin(a)xenosoft.com> >There ARE many things that the WD will do that the NEC won't, including >writing much sooner after the index pulse, IGNORING certain fields in the 765A writes or read sonner than base 765 and the 37c65 even shorter. It doesnt ignore fields in a multisector read/write however if the sectors are written with a interleave it will also keep things in numerical order. Add to that a full cylinder read does not bring all the non data crap that formatted media requires to marks all the data spaces. The real beauty of that is if you have real DMA you can fire it up and read a whole cylinder and all your buffer has is neatly ordered data if the read was successful. That latter feature is nice if your doing a caching scheme. >Allison could probably gives us a more comprehensive and authoritative >list. Yes I can. Allison

New Finds

I know IBM had a version of AIX that ran on these. Or was it just that funky Microkernel OS/2 thing running on one of these with AIX running at the same time? I know I saw that at a trade show once in DC, that was cool! Zane

Kwanzaa... [was: Troll got me (was: Is there no end)]

by DAW＠yalepress3.unipress.yale.edu

! ... whitey's holiday, and crackers are the enemy (their ! terms, not mine... I get "whitey"... I get "white bread"... but ! cracker?!? I would ask when visiting my inlaws... but I would ! just get my ass kicked, or worse, shot). Chris - Now, I'm a honkey (now what's the origin of that?) just like you... (like you couldn't tell by the name! :-) I think the term "cracker" is because, ISTR, crackers and bread made basically the same, except crackers don't have any yeast. Both light colored... ! As to the REAL reason for Kwanzaa, I have no idea, but I do ! know, around here it is entirely a racial thing, and the ! only people that really seem to take it seriously are the ! inner city high crime area Afican-Americans... which ! unfortuantly gives the whole thing a bad notion up here. Its ! a shame really, as I am sure there was a real reason for it, ! but like many other things, it has been badly perverted by a ! very very select group of people who decided to use it for ! their own agenda. What's that cliche saying?

MITS 2SIO serial chip?

I just dont get all that excited about it. I've designed a cpu and built it years ago, it out of my system and not worth repeating. Any cpu I'd do would need software and that means it would likely be a copy of something... likely something I have. Allison

Fw: Old Atari ?

This gentleman has Atari & Commodore systems in Iowa that are available, someone please give them a good home and not make his equipment into epay.com fodder....
