Basically it comes down to the address munging that's being done to prevent spammers from harvesting is also preventing legitimate browsers from identifying the authors of messages individually.

Perhaps turning cctalk(a)classiccmp.org into cctalk2003ATclassiccmpDOTorg would fool the harvesters and allow people to reply to an individual.

Reading various format 5.25" floppies on a PC

by julesrichardsonuk＠yahoo.co.uk

OK, apologies first as this has been done to death at various times in the past, and now I come to need the info I haven't got the willpower to piece it together from archives of several thousand posts :-) I'm trying to organise and back up all my data (primarily on my main PC system) - but I'd also like to make images of the disks for some of my classic platforms whilst I'm at it. I don't have any kind of fancy floppy controller, just whatever comes in a standard PC (I do have PCs running Windows 2000, Windows ME, Windows NT, Linux and DOS so I'm not too fussy about OS choice) I have various 5.25" floppy drives lying around, although I *assume* the 1.2MB drive will electrically read all of my 5.25" disks (whether the controller can understand the raw data coming off the disks is another matter of course) I've got disks for the following machines which I'd like to initially back up: Acorn BBC / BBC Master / Cambridge Workstation (I believe these are all the same low-level format even if filesystem structure is different) DEC Rainbow (B model, if there's a difference between that and the A) Apple (Apple ][, //e and /// - again I believe low-level structure is the same for all 3?) So, in an ideal world, what I'd like to be able to do is use some piece of software on the PC and suck an entire image off each disk, archive it onto tape / CD / whatever, then at some point in the future be able to use the same software on a PC to rebuild from those disk images such that they'll work in the machine they were intended to. I'm not even going to think about the Amiga and Mac 3.5" disks for now; I know the PC controller won't handle those - and all the stuff on cassette tape can wait too! :-) (the couple of Macs I do have might be a better bet for this job, but unfortunately none of them are networked and so I couldn't get the data off them to a place where I can store it easily) cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

Seeking a Cromemco C-10

by kurtk7＠visi.com

I have been looking for a C-10 for some time but lost out in a recent auction. My bad luck, so I doesn't suppose anyone might know where I can find another C- 10. I know its a long shot but I thought I would ask. Any suggestions would be greatly appreciated. Thanks, Kurt

webby list archive administrivia (was Re: Tek 1230)

No, they can identify the author by name. What it really comes down to is that the address munging provides a mailto: link which makes it easy for folks who find the archive pages to generate an e-mail message to the list (which is OK), and that these folks don't realize that they're about to post to a mailing list and that providing some context would be a good thing. If they realized that, they could perhaps write "w/r/t foo's message to this list on date mm/dd/yy on the matter of bar" or even copy and paste some of the webby archive page into the message. What might be helpful would be for the webby archive pages to not have that link right next to the poster's name, but instead to have a "post a follow-up to this message" link somewhere on the page. I have no idea how to do this using pipermail though. -Frank McConnell

I've had occasional useful contacts from people who've seen my address in the archive, and I'd rather see it munged in some human-reversible way than simply replaced with the mailing list address. -- Pete Peter Turnbull Network Manager University of York

Tek 1230

by dan.fellman＠lmco.com

Hi, I came across your 8008/8080 web page while searching for info on old Tektronix logic analyzers. I recently bought a model 1220 analyzer on eBay which is very similar to the 1230 you describe. It didn't come with pods or probes, but I thought I might be able to improvise something. After some study of the front panel connector with an ohmmeter and voltmeter, I believe I've identified the data lines, power and ground, and some other inputs that must be used for clocks and control signals, but the analyzer doesn't respond to any of the signals I feed in. It seems to have some mechanism for recognizing that a compatible Tek pod is attached. The input channels just show up as "unused" when I attempt to acquire data. I suppose it could be some setup step I'm missing, but I don't see anything on the various menus that looks like a pod enable. I'd appreciate any insight you can give me into this problem. Also, are you aware of other pods that go with these units besides the P6444's? Thanks, Dan

Looking for Burroughs B20/BTOS software/hardware/docs

by alanp＠snowmoose.com

I am getting a gaggle of Burroughs B20/BTOS machines through eBay. I developed software on them for Burroughs back in the late 80s. Didn't really care for the machines at the time, but I thought the expansion capability by adding "slices" was pretty neat. Does anyone have any B20 "slices" or any BTOS/CTOS software or documentation that they want to sell? alan BTW, long ago I promised to scan in some of my VAX documentation, but life keeps getting in the way. I hope to get that stuff done in August now.

Making holes in magnetic tape

by dwightk.elvey＠amd.com

Hi John Although it is a serious issue if the tape is folded where the signals are, where the holes are isn't. Just fold the tape in two diagonal directions and cut it with sizzors. The hole will be a square but the computer doesn't care. You'll need to erase the tape and reformat.
