The ongoing thread about the origins of C and UNIX have made me wonder about something I was told years ago: "UNIX was written as a host platform for C *development* and was not originally envisioned as the production platform for applications developed on it." In other words, the intent was that developers would write code on UNIX, then port it to an "application-oriented" OS for production. Is there any truth to that? Doc

Not just bit-aligned data: some processors from that same broad era (e.g. iAPX432) didn't even require that instructions be byte or word aligned. I think the point folks are missing is that it isn't the processor that defines the standard data types, but the language. I used to be more condescending towards the attitude that the-whole-world-is-a-stream-of-bytes (having worked with many I/O devices and languages and computers that had far more evolved record concepts) but here i am in 2011 and if I can coerce anything into a stream of bytes - I've got a lot of tools for working with that.

We know where you stand already. I would hardly call Tony self-righteous. He does have strong opinions and lives by his convictions, but I have always got the clear impression that he accepts other people's right to do as they please with their own stuff. He will try to convince you that you should reconsider, if you propose doing something which he thinks is wrong, however I don't think that the connotation "especiallywhensmuglymoralisticandintolerantoftheopinionsandbehaviorofothers" of the word "self-righteous" (from dictionary.com) applies. Being intolerant is not the same as disagreeing and trying to convince people they are wrong. Intolerance implies refusing other people the right to their opinions. Irony does not always go down well either, unfortunately. /Jonas

OT(?) : HP1630D Logic Analyser

by ard＠p850ug1.demon.co.uk

This may be a bit off-topic, although the instrumetn in question is certainly well over 10 years old, it includes a classic microprocessor (68B09, along with a a 6829 MMU, I've never seen one before), and is certainly suitable for repairing classic computers... Anyway, I've been given a really nice toy -- an HP1530D Logic Analyser. The -D model ahs 16 timing channels (which can be confgured in blocks of 8 as state channels) and a further 27 state channels. HP got a lot right in the design of this instrument -- the fact that the pods can only be disconnected after rmeoving a cover plate means that the pods are unlikely to get spearated from the unit and lost, for example. Anyway, given it's a -D (and not a -G), is there anyting I should know about it? Any fun tricks that are not immediately obvious from the manuals (I don't have these on paper :-(, I've been looking at the ones vey kindly provided o nthe Agilent web site) -tony

Ping Al Kossow, bitsavers content question...do you happen to have....

Hi Al, Do you happen to have copies of the following IBM doc available? This is all I/O related, not sure if it's from the 370 days or later. MVS/ESA Component Diagnosis and Logic: EXCP Processor (LY28-1477) LY28-1487 LY28-1488 LC28-1166-5 I noticed you've added a bunch of great IBM doc recently in addition to all the other great IBM doc you have been hosting. THANK YOU for your site and all the great work you are doing!

Let's talk NeXT - Re: Steve Jobs -2011

by tshoppa＠wmata.com

>> How, exactly, is running something in a web browser "more versatile" >> than running a purpose-built app with a GUI? WTF? To me a "purpose built app with a GUI" is the very definition of "vendor lock-in" and "A PC for every function". To me "vendor lock-in" means "look you have the versatility of running it on this one PC with a mouse and a keyboard and if you want to do it any other way you can pay us for as many copies as you want!". Whereas a web interface means that the display terminal and application server are now decoupled with a strong implication of scalability up the wazoo. (I know, it's all too easy to make it unscalable, or to embed Windows Controls in a web application and tie the browser to a specific Windows build.) It also implies that multiple applications are accessible simultaneously just by opening more browser windows - and means you don't have to swap 10,000 PC's every time you upgrade the central server. To me a web interface is way preferable to say a 3270 for filling forms. I know, the hot-shot mainframe app people had some pretty slick user interfaces on the 3270's for some popular mainframe applications. I've seen good ones and I appreciate them. But the vast majority of 3270 user interfaces sucked rocks. I'm not saying there aren't some really sucky webpages out there but custom roll-your-own-GUI-inside-the-web-page design seems to be very much on the decline, thank god. Tim.

PS2Encoder PCBs available

by brain＠jbrain.com

PS2Encoder (http://www.go4retro.com/2011/03/11/micro-project-ps2encoder/) PCBs have arrived. I had planned to offer as just a PCB and a kit option, but if folks are interested in an assembled version, I'd like to know. It looks like the PCB is $5.00, a PCB + a AVR + the minidin6 = $16.00, and a complete kit is $21.00. An assembled unit looks to add ~ 5.00 to the price. Please let me know if you have any interest in any of the options. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Because they think they can make more money by selling the pods separately? It happens with old cameras as well, the camera is sold without its special take-up spool, which is sold separately for as much as the camera itself. And with cars, sell an old car in parts and you will get much more for it than if you sell it intact. /Jonas

They were proprietary in their origins but with open documentation and set a very good standard for how to implement desktop interfaces "right". ADB's concepts are strong and alive in USB. Appletalk's concepts are strong and alive in Ethernet. (I know, Ethernet predates Appletalk.) Tim.
