--------Original Message: Date: Wed, 6 Jun 2007 08:34:37 -0500 From: "Dave Dunfield" <dave06a at dunfield.com> Subject: Re: TESTFDC usage <snip> To completely test the FDC, you need to check Single, Double and Double/128 at each of 250, 300 and 500 kbps rates. These are represented in a standard PC at: 250 = 5.25 low-density drive only, 3.5" low-density diskette 300 = 5.25 Low-density diskette in high-density drive 500 = 5.25" or 2.5" high-density diskette So to check all possible data rates without a 300/360 modded drive, you need to run two tests - either the 5.25" LD and HD drives, or a 5.25" HD and 3.5" drive. ---------------------- I also wanted to do some testing but, despite our off-list correspondence, I'm still confused: 5.25" drive, 3.5" diskette ??? 2.5" diskette ??? 3.5" drive - LD or HD? Exactly what tests should be run with what size/density disk in what size/ density/speed drive in order to get a complete picture? mike

TESTFDC usage

by arcarlini＠iee.org

I've been checking through the stuff I have around here and I've decided that I have a few surplus PC mobos that I'll be getting rid of (via a certain auction site). Before I do I thought I'd try them out with TESTFDC and see what it says. I have three 5.25" drives (of currently unknown functionality) which I could use. One is a DEC RX33, one is a Tandon TM75-8 and the last one is a Sankyo (or that might just be the motor manufacturer :-)). I also have whatever is sitting in my main machine, but I'm not keen to drag that out just foir fun! I also have a few 1.44MB 3.5" drives, but they've not been used in quite some time, so heaven knows what state they are in. So what do I need to do to extract the maximum useful information about these motherboards (aside, that is, from checking that they are not already on the list :-))? And exactly what media will I need? Should I test both 3.5" and 5.25" (I've not tried the 300/360 mod yet; I may do in the future, but for now I'd just like to get some testing done)? Anything to watch out for? Any particular version of DOS recommended (I have 6.2? kicking around, would FreeDOS do if that is easier to find)? Thanks Antonio

Anyone know anything about old TEC Terminals?

by classiccmp＠memory-alpha.org.uk

Hi, > Well, I don't know whether they're "plasma/LCD" or not, but I >find I get dramatically better picture quality out of flat-screens >as compared to CRTs. Well, the last two CRTs I bought are flat-screen so I'm not sure exactly what you're getting at. The biggest problems with LCD panels are colour registration, black level/contrast and response time. Even with top of the range panels, their comparatively slow response time leads to very noticable blurring when things move around on the screen - and I'm not talking about games here, I find this blurring totally unacceptable even when scrolling text windows, etc. And the colour/contrast/black level problems are a total show stopper when I'm dealing with video.... > I don't know whether this just means every CRT I've used has been crap, >or perhaps I *am* "profoundly blind", but even if so, in my experience >the comparison stands. I wouldn't have thought so, IME even the cheapest/crappest CRT is head and shoulders above even the most expensive LCD panel. It all depends what your expectations are.... TTFN - Pete.

Databooks: keep or toss?

I'm not sure > why - > maybe it's more resistant to absorbing moisture from the air or > something. > Moisture is a problem only if it's really high (mold predominantly, although sizing can soften and stick pages together). The big problem with many paperbacks is the so-called "high acid" paper with appreciable quantities of lignin in it - the lignin changes into acid and causes the paper to self-destruct. Think yellowing, crumbling paperbacks... I'm not sure what the paper of choice for databooks is, generally if a book uses sized bond paper it's not at highest risk, but for the most part wood paper made before the '80s will have some degree of risk (and more modern papers that are not acid-free archival grade). LOC (Library of Congress) has a fairly large group devoted to this problem, and a process fior neutralization that works pretty well (although if you do it wrong or make a mistake stuff bursts into flame). They point out that it is "not recommended for those who are not professionals".

DataGeneral documentation

by henk.gooijen＠oce.com

Hi all, I have put up for auction on eBay a stack of 6 inches of DataGeneral (micro) NOVA documentation. The item number is 170120175007 in case you are interested (shameless plug), but the other reason I would like to mention this auction here, is that if you are not looking for the original sheets of paper (as a DG collector), but you only want the printed information, you do not need to place a bid! I have scanned the whole pile and will send it to bitsavers (> 500 MB). thanks, - Henk.

Databooks: keep or toss?

General book conservation techniques can be found here http://www.philobiblon.com/gbwarticle/gbwjournalarticle.htm My personal preference is to debind and scan. National and AMD data books used very low grade paper, as did the people who produced IC Masters.

Anyone know anything about old TEC Terminals?

by classiccmp＠memory-alpha.org.uk

Hi, >....hard to get new CRT monitors now and the cheap LCD ones are >rubbish! Cheap nothing, I've never seen *ANY* LCD monitor (either fabulously expensive or dirt cheap) which I would describe as being anything other than diabolical! The same goes for LCD TVs too - and plasma sets aren't much better in my opinion. The people who buy these things must be profoundly blind if they're satisfied with the picture quality produced by the current generations of plasma/LCD screens, the technology simply isn't anywhere near good enough yet. >....We'll soon be reduced to scouring eBay for real monitors :-) Quite, which is why I recently spend several months tracking down a very nice, 32" wide screen *CRT* TV set; which I got for next to nothing since the market is currently flooded with this LCD rubbish. :-) TTFN - Pete.

DECnet on the 'net

by bob＠jfcl.com

> I seem to remember that there was a group of people bridging their > DECnet over TCP to connect various sites over the Internet. I can't > seem to find them this minute. It's called HECnet (don't blame me - I didn't think of that name :-) We've got several dozen machines at a dozen or so locations around the world connected, and we're happy to have more join. To connect, you'll need either - A VAX running OVMS and Multinet (they have a hobbyist license, and also a DECnet-over-IP implementation). If you have multiple local DECnet machines and your VAX is a DECnet router, then they can all play with this one gateway. Or - A Un*x box of some variety running Johnny's DECNet bridge program. In this case the Un*x box is in addition to whatever other DECnet machines you have on your local network. You'll also need an Internet connection (of course), and a _static_ IP. Contact me off the list if you're interested in connecting and I'll point you in the right direction. Bob Armstrong

DEC H775-BA and H3213-3400 in Kansas

by wulfcub＠gmail.com

While cleaning out a storage area (indoors), I found an H3213-3400 psu and an H775-BA remote battery backup unit. As I recall, these both came out of a Xerox 9700 controller cabinet, and the H3213 worked when we last fired it up. The BBU hasn't had a battery pack on it in at least 11 years (as long as I've been with the company), so I have no idea whether or not it works. They're both free for the taking. Pick them up, or arrange to have them shipped. Both are fairly heavy and the 3213 is rather large. Located in Wichita, Ks. May trade for C= 128 gear. Thanks! --Shaun -- "If you live to be a hundred, I want to live to be a hundred minus one day, so I never have to live without you." -- Winnie The Pooh http://www.lungs4amber.org

Thursby's was originally written in Mac Pascal. We ported that to C on top of the Amiga's SANA II network stack, which allowed you to run other network stacks like TCP/IP at the same time. It worked with X Window and included NCP, Netmail (which I wrote from scratch), network file copy and file access listener. - John

DEC parts code reference?

by julesrichardsonuk＠yahoo.co.uk

Out of interest (and to my shame, without googling first :-), did DEC (or a third party) ever produce a reference listing of DEC "parts codes" against function (e.g. RK05 = removable disk, KL11 = serial interface etc.) I'm trying to sort out our documentation archives, and DEC seem very good at just listing the codes as title ("DZ11-C technical manual" etc.) on a lot of their docs - meaning I have to skim pages to get a handle on what the thing actually is) cheers Jules

That's a copy of stuff rescued from Decwrl after Compaq took over. I'd almost forgotten all the time spent in Runoff. I'd used to say that I produced the last implementation of DECnet Phase IV in PathWORKS for Windows 95. But these guys doing the Linux DECnet have taken that away from me. http://linux-decnet.sourceforge.net/ If you're interested in learning how DECnet works, that implementation is freely accessible. PS: There is a Debian MOP daemon here http://packages.debian.org/unstable/net/mopd I seem to remember that there was a group of people bridging their DECnet over TCP to connect various sites over the Internet. I can't seem to find them this minute. Dave.

More Seattle Spring Cleaning - HP 7980A / M4 9914 9-track tape drives

by glen.slick＠gmail.com

Anyone in the Seattle area looking for a 9-track tape drive project? I have one HP 7980A HPIB and two M4 9914 SCSI/Pertec drives. These are front loading / auto loading units. Unfortunately they need some work to be fully functional. The problem with both M4 units may be limited to the tach rollers not accurately rolling along with the tape motion. I had one of the M4 units working briefly a couple of months ago. If anyone local wants these let me know with a private reply. These are too big and heavy to deal with shipping. -Glen

Apple II

by swtpc6800＠comcast.net

There are various news stories about the 30th anniversary of the Apple II computer. My favorite story is that I had Apple II serial number 2 for evaluation. At the time I was working at a computer store in San Mateo, California. The owner, Chet Harris, when down to the Apple factory one Saturday in June of 1977 and came back with the first two completed units. (This must have been June 4.) He had sold serial number 1 to a friend of his and I got serial number 2. After a few weeks the power supply failed and it was sent back to Apple. Jef Raskin ended up with this unit. You can read about it here: http://www.swtpc.com/mholley/Apple/allied_computer.htm Apple started selling the Apple II boards around April of 1977. They were having problems with the plastic case, the early production units did not have the vents on the side. You can see that in the picture of serial number 2. http://www.swtpc.com/mholley/Apple/Jef_Raskin_Apple.jpg A customer at the store, Bill Kelly, was doing the advertising campaign for Apple and he got a prototype Apple II board. I built a linear power supply for it and traded it to him for an Intel SDK-80 board. Here is his web site: http://www.kelleyad.com/Histry.htm Here is a page that shows the my SDK-80 board. http://www.swtpc.com/mholley/Homebrew/Homebrew.htm Even though I went to the Homebrew Computer club, looked at the Apple I, and I had use of a Apple II; I have never owned an Apple computer.
