Need Fileware twiggy diskette picture for Wikipedia

by dave＠661.org

Someone informed me that the Fileware diskette image I uploaded to Wikipedia has unclear copyright status. See https://en.wikipedia.org/wiki/File:Fileware-floppy.jpg. Would someone with a good specimen please scan it and upload to Wikipedia or send it to me? -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

However, I will always post notifications of new lists here and on the VCFed forums 24 hours before I unleash them on the FB groups, which results in a deluge of activity. In this way, I give you guys first stab at the action on the new stuff before the hordes descend upon it. You are welcome. As always, please contact me directly by e-mail to inquire about an item. Thanks! Sellam

I'll also vouch for Sellam. His prices are a bit higher than I might prefer, but he's a straight dealer as far as I've ever seen; I bought an Apple IIc from him and he gave me no trouble at all about exchanging it when the board turned out to be cracked.

IBM PS/2 Model 70 or compatible floppy drive wanted (Or help with current one?)

by mokuba＠gmail.com

Hey all, i'm having a fair amount of trouble with my PS/2's floppy drive... wanted to back up my BBS and none of the disks i put in would read or format! Oddly though, it WILL boot a disk that's inserted on power-on. I hear it try and hit the disk a few times while in dos repeatedly before failing with the R/A/F options ... and format tries to read it, then goes attempts to format it, and can't find sector 0 ..... I'm really confused about those symptoms since it boots the only bootable disk I had on hand - ironically spinrite 6 (I'm aware of how useful it is...) - so i'm looking at replacing it ... or figuring out what's wrong with it that it can boot a disk just fine, but not use one while in DOS ? .... and by wiggling the floppy a bit I just got it to format a disk while in the ... drive, and now it's making the noise it did before and stalling occasionally. Perhaps the disk just isn't catching fully? -- Gary G. Sparkes Jr. KB3HAG

FYI, it is unlikely there would have been a VCF without Sellam. He basically started it (with his own money) and continued through the first 10 years or so. Many others help support VCF (and continue to do so even though Sellam backed out some number of years ago.) I, for one, fully support Sellam in his effots to move out his inventory, and have never seen him sell anything at 10x prices.

DNS and Registrar

But it will probably work > 98% of the time. If you're comfortable with it, more power to you. I would likely do something more like I'm doing now, run the master name server (MNAME field in the SOA record) on the DSL and have somebody else with a more robust connection (DSL had issues where I'm from) do a slave zone transfer and be the listed Name Servers (NS records) that the world talks to. I actually do that now with my VPS being the MNAME server and my VPS provider doing slave zone transfers off of me. Note how the registrar is not part of that mix. ;-) > The biggest thing to watch for is the lax rules for transfering > domains.? There was a problem with that, but most registrars allow locks > now that impede the movement of domains w/o a bit of work. That sounds like you're talking about moving domains between registrars, which is decidedly different than and independent of where DNS is hosted. Admittedly the registrar has to point (delegate) to the DNS hosting provider. But it's fairly easy to move domains between registrars without even logging into a portal at the DNS host. > Used to take a couple of emails to highjack a domain, as there wasn't > even a notification to verify that the transfer process email was > requested by the owner. Ya. Registrars have had some deficiencies over the years. I think they are getting better. > You are strongly encouraged to use a third party "professional" DNS > service, but it only really need to be up reliably. ~whistling~ ? ~quiet~ ? I'm sorry, did you say something? No. Never mind. I'll go back to what I was doing. ? ~whistling~ I mean that as a joke. I let a LOT of what companies that are trying to sell to me go in one ear, sanity check it, and then go out the other ear. I'm of the opinion that a static IP is the biggest requirement for /most/ DNS service. I.e. somewhere to have the registrar delegate the DNS to. Beyond that, I'm happy to delegate sub-domains to people on dynamic IPs if they want them. It's possible to put DNS a LOT of places that don't qualify as "Best Practice". Most of them will work most of the time. > We have the dual providers for the node my friend runs, as we know from > the phone companies and providers that though the DNS is over the same > 12 pair wire into his house (another trick), the CO actually has the > DNS switches on different racks and UPS's. Which isn't a bad precaution. That's probably okay for most things. But it's still subject to Backhoe Bob and the fade that he can induce. That's why I have my master that I can do anything and everything I want to, and outsource to slave secondaries. Linode, my VPS provider, has five different DNS servers that (I belie) are geographically diverse. It will be quite a bit harder to take out all five of their DNS servers. Plus, I don't have to pay for connectivity in five different locations. ;-) I'm curious, you said DSL. But that could be anything from 1.5 Mbps ADSL to SDSL to VDSL. Each of which have different capabilities and SLAs. Other than the backhoe fade taking out both connections at the same time, higher quality DSL with SLAs is probably okay to do. I think the official recommendation for big (think root level) DNS servers is to have each server in a different network, where network is defined as /24 (or larger), preferably under different ASNs. But that's not a /requirement/, especially for smaller DNS operators. > thanks You're welcome. -- Grant. . . . unix || die

Anyone have an Ethernet interface card for an AT&T 730 terminal?

by aek＠bitsavers.org

I just finished taking pictures and dumping the firmware from a 730X terminal but it turns out it has a Starlan and not an Ethernet interface. It would be nice to get a firmware dump from an Ethernet card. A start of a 630 driver is in MAME. http://bitsavers.org/pdf/att/730/730X It also appears the keyboards for the 630 and 730 aren't backwards compatible with the other 6xx products and the 5620. 5620 keyboards need -12v which the 630 or 730 don't supply, and the 610 keyboard doesn't appear to work either. Josh took a couple of pictures of his 630 keyboard and even though they look similar, the earlier keyboards were made by Teletype and the 630 is made by Keytronic.

Identifying some boards

by kylevowen＠gmail.com

I picked up these boards many weeks ago, but haven't photographed them until recently. Some of them are pretty disgusting, but some of the others look alright. Anyone have any idea what these came out of? Some are labeled Gould, others are labeled Encore. http://imgur.com/a/d9iK9qb Thanks! Kyle

Recovering the ROM of an IBM 5100 using OCR (among other things)

by boris＠summitclinic.com

That was a very interesting read! The type of thing I could see myself doing over 40 years ago when once I'd come up with a neat idea and either did preliminary coding or hardware design suggesting it would work I'd jump right into it and find optimistic 1 month project timelines stretching to 6+ months. My approach now would be to just use a logic analyzer or a number of Propeller boards to sample all of the lines from ROS as very sedate clock speed that the 5100 uses. Still, this has applications beyond original goal and could use it to acquire patient lab data from hospital EMR's which are increasingly locked down. Used to be I could export a patients lab results to a text file easily to graph them out vs time or look at correlations between various lab values. Now that's forbidden as one is only allowed to look at them on the screen or use the abysmal graphing functionality which is very poorly coded and makes a PDP-8 doing the same functionality seem like a supercomputer. Thus, one could simply point a cell phone camera at the screen, record the lab results scrolling by and then do OCR on the series of images to create a data file of all of the lab results one is interested in. I've just photographed results on a screen as takes less room than another sheet of paper. >This is *epic*. > >https://github.com/stepleton/5100NonExecutableROSDecode/blob/master/WRITEUP… > >-- >Liam Proven - Profile: https://about.me/liamproven >Email: lproven at cix.co.uk - Google Mail/Hangouts/Plus: lproven at gmail.com >Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven >UK: +44 7939-087884 - ??R (+ WhatsApp/Telegram/Signal): +420 702 829 053
