Seems to me that nearly all ribbon cables use even-numbered pins for signal and odd-numbered pins for ground. So signal and ground lines alternate in the cable. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

I'm probably the last person still using Microsoft Mail. It works okay, but I can't find any information about security holes (or lack of them) in this program, and it does not include the headers in messages which I forward, so it's no good for reporting spam. Sellam, I tried Pegasus v4 and the windows kept popping up in really odd locations and sizes. It also has *way* more bells and whistles than I need. Doc, I tried Pine, but the Win9x version requires that I be on-line to read email. I want to send/receive, logoff, and then read and compose new mail. Other than that, it looks okay. Can some one suggest a simple offline email handler that isn't giving that "come hither" look to every Trojan on earth? And that's free? Glen 0/0

Ancestry.com does this very effectively. They have a message archive, but then you nring up a message, you don't see the RFC822 e-mail address, just the name of the poster. Like with E-Bay, if you want the actual address, you click a link that takes you to a different page. Here is where the difference begins, and why Ancesrty's way is much cooler than E-Bay's (but then _cooler than E-Bay_ isn't hard to do). Anyway, you get a page where the host system looks up the actual e-mail address, then constructs a graphic image ON THE FLY that is a "picture" of the poster's e-mail address. Gonna take a hell of a bot to break through that... Regards, -doug q

ZX-TEAM meeting and Webcam

by acme_ent＠bellsouth.net

> From: Stan Barr <stanb(a)dial.pipex.com> > Just curious, but what do you guys *do* with ZX81s? I've got one rebuilt in > a large box with loads of i/o ports and a2d converter running multi-tasking > Forth, but I've not plugged it in for a while... Okay, check out: http://home.freiepresse.de/befis/zx96_e.htm Then tell me what you *can't* do with a ZX81 ;>) We can: scan documents control overhead projectors control CNC tools and other robotics run BBSs play audio CDs load programs from CDs burn EPROMs In addition to the above, we also use: AT- and PS/2-style keyboards 5.25" fdds 3.5" fdds IDE hdds LCD screens I've heard that a TCP/IP protocol handler will be unveiled at this year's meeting. Sure, some of these operations are slow, but the point is that we're doing a *lot* with "obsolete" hardware. If we can get this kind of functionality out of a Z80-based system, what could *really* be done with a 486-100, P233, or P4-2.2 GHz system, given the time and brainpower? Sellam once said that the ZX-TEAMers were "fanatical hackers." How else is science advanced, other than fanatical hacking (and dumb luck)? My personal project is WIN-ZX, which will perform many of the tasks Windows 3.1 handled for the PC. Presently it requires a 64KB system with a MEFISDOS-based IDE hard drive, but I hope to trim it down to 16KB and cassette tape. Hope you join us for the chat -- Glen 0/0

Yeah, and if a bunch of genealogists can come up with it, I'd be ashamed to be an IT professional if *we* couldn't do at least as well... -dq

Semi-OT: PMac 6100 DOS

I have had this 6100 for over >a year and haven't run across the HDI-45 adapter for less than $15-$20 >shipped. There are literally DOZENS of these on eBay... as long as you don't mind 3rd party ones (if you want a true apple one, you might actually have to look a few times over the course of 2 weeks before one shows up... even those aren't exactly rare). But, you are right, almost all of them end up in the $20 range after shipping (and many before shipping). Again, it isn't because of demand, but rather because 90% of them are 3rd party, all sold by the same person, and all with starting bids of $9.99 + $10 shipping and handling. Almost all go unbid, but because of that, the few that get listed by someone else for lower prices, get driven up by people trying to get a better deal (or from the one guy slamming the bids to make his the cheapest for all I know). -chris <http://www.mythtech.net>

iSBX-251 Bubble Memory

by ken＠seefried.com

My latest score is an iSBX-251 bubble memory card. Tres kewl. The bonus is that it showed up with a manual complete with schematics. I've got to get a scanner working so I can get it on line, but if anyone has a question, drop me a line. Ken
