"A bigot is a person obstinately or intolerantly devoted to his or her own opinions and prejudices." Gotta admit, that sounds like you all right, at least in this context. So, in your view someone who objects to bigotry is also a bigot? Interesting logic... @ Richard: Give it up. No point in arguing with folks who have a need to tell us at every opportunity that they're smarter, better, whatever, than all those Windows lusers out there; just smile tolerantly and ignore them. We know who *really* "gets" more, MS or 'nix types, don't we...? But hey, it's all in good fun. mike

VAX on a cell phone

In that vein, I have spent some time over the past week or so setting up my cell phone (an HTC Evo running Android) to emulate a VAX by running SIMH. http://worldofvax.blogspot.com/2010/08/compiling-simh-emulators-for- android.html And then using a VT125 for its console: http://worldofvax.blogspot.com/2010/08/htc-evo-and-vt125.html Enjoy the insanity!

3270 Personal Computer

by shoppa＠trailing-edge.com

Further from the details of the OP, but a little closer to the spirit of the OP and more DECish: I remember students calling up when they had trouble running their Fortran homework programs through the compiler on the "VT100 computer running VMS". Even today the computer hardware on the desk is often blamed when it's really really some backend website that's FUBAR or Microsoft's Windows getting infected by spyware. And as long as we're talking about people who get confused by the label on the computer devices in front of them, where's the guy who swears up and down that he has OS/2 for the PDP-11 and that he was using the predecessor to Fortran in 1982? None of the above people are evil, just misguided and in need of some nudges. But it's sad that the computer industry is so confusing that the nudges are needed, and that the folks who decide what brand gets buys are so often swayed by the brandname of something on their desk rather than reality.

GET LAMP is here

I agree. I often need to read several messages further on in a thread to figure out what is being talked about. "XYZZY" or "PLUGH" would be more recognizable. But, like many puzzles in Colossal Cave, it's obvious AFTER you know it, but not before. > follow such a URL involves almost as much work as you getting to see one > of my workshop notebooks. And I want to know if that effort is worthwhile. If we could scan the entire existing collection, then the effort probably would be worthwhile. I'm on dial-up right now. A URL with no explanation just seems rather inconsiderate. Oh, well. But, it's not just here. The college adminiatrators tend to send a 4 line paragraph as a MICROS~1 WEIRD attachment with no explanation other than "FYI" or "read the attachment". Meanwhile, the "Help Desk" sends out several announcements per week saying, "Please stop opening attachments that come with email, and please stop replying to messages that ask what your password is!" -- Grumpy Ol' Fred cisin at xenosoft.com -----------------------Reply: I'm with Tony and Fred on this one: a hint of what a URL is about would be nice and show a little consideration. I'm on dial-up as well, often incurring per-minute long distance charges, and read my email off-line; if there's no clue what a link is about then I just treat it as spam no matter where it's from instead of investing time and money looking at something that probably won't interest me (especially when some sites take 3 or 4 minutes at 56K just to open the page). mike

Speaking of Bernoullis...

by mcguire＠neurotica.com

I'd love to use 5.25" Bernoullis as removable storage on a PDP-11 via a Qbus SCSI host adapter. Does anyone know offhand if any of the common boards, like the CMD CQD-223, will properly handle a drive with 256 bytes per sector? I know it's a bit odd to think about, but it seems like a good idea to me, if it'll work. If nobody pipes up and says it definitely won't work, perhaps I'll dig up a Bernoulli drive and try it at some point. -Dave -- Dave McGuire Port Charlotte, FL

Here are several: http://freshmeat.net/projects/linuxserialsniffer/ http://freshmeat.net/projects/serlook/ http://www.serialmon.com/ http://www.gumbley.me.uk/scope.html Some of these use one port and a special sniffer cable, some use two ports. There are other sniffers out there, I'm sure, but these were the ones that took less than two minutes to find. I haven't used any of them, so I can't recommend one vs another. I have commercial-grade gear for this (HP4951), but with all the options out there, you should be able to find a PC-based one that does what you need. -ethan

M51976FP pinout?

by ard＠p850ug1.demon.co.uk

I am looking for a pinout or datasheet for a chip labelled M51976FP. It appears to be made by Mitsubishi, it's a SMPSU controller in a 20 pin SOIC package. I have the data on the M51977, which is similar (I think), but some pins are clearly different. Looking on datasheetarchiver and digchip didn't find anything. And a google search (as ever) found plenty of people who sould sell me 100000 of them, but nothing else). [It's uised in a PSU modile in an HP tape drive that I am working on, so it does have som relevance to classic computers0. Thanks in advance for any help -tony

retr0brite not so right?

by feedle＠feedle.net

Depends. I'd pay more for a working Replica I than a broken original.

does anyone know what this is (C64 Snapshot cartridge)

by chrism3667＠yahoo.com

http://cgi.ebay.com/Snapshot-64-Cartridge-Commodore-64-/170523686285?pt=LH_… the seller is too brain dead to describe what it is, despite stating that it's tested and working. I seem to have a vague recollection of what this is, but actually I'm not totally sure.
