The uIEC/SD I bought from Jim Brain was delivered Friday night (USPS was actually unable to deliver for several days in our area). My mail is currently going to a different location than we're living, so I picked it up yesterday, and retrieved my customized C64 from storage, and got everything plugged in last night (this was the first time we'd been able to get our car out of the driveway in over two weeks). Once I figured out how to use it, all I can say it is seriously cool, way better than my MMC-Replay for dealing with D64 images, and it was a lot cheaper! I'm even able to use it with the MMC-Replay plugged in so I have my Ethernet connection. With the MMC-Replay I was only able to get one or two D64 images to work, with the uIEC most I've tried have worked. I've been playing "Temple of Apshai" all day and having a blast! :-) Now to decide if I put it in some sort of case, or if I mount it inside the C64 somehow. Zane -- | Zane H.

FFS: Atari 1025 Printer box

The SX-64 box has been claimed. This is the next one up. Same deal, free for cost of shipping (I'll ship it in a larger box so the PO doesn't mar up the fine Atari graphics) from 60074. -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

That's one interpretation, but it just considers the scarceness factor. You also have to figure in the saneness factor. If you want a punched card era memorabilis, a drum is a heck of a lot easier to ship, store and display than a whole keypunch machine.

FFS: SX-64 Box

by silent700＠gmail.com

Nope, not "box" as in slang for "computer" or "machine." This is just the cardboard box (well ok, also the Styrofoam inserts and a plastic bag) that the SX-64 came in. No serious collector should be without one! Apparently, I'm not as serious as I thought, because I've got three SX-64s (each broken in some unique way) and I've decided the box takes up too much space. None of them matched the serial # on the box, anyway. So if anyone wants it, it's free for the cost of shipping from 60074 (or if you're local, come pick it up.) Please give it a home. Even though I've got to shrink my collection and reclaim storage space, I still can't let something as simple as an old cardboard box go to the landfill. -j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

Looking for a mac iifx and an apple 2e

by brianlanning＠gmail.com

Hi everyone. I'd like to add a mac iifx and a later model apple iie (or possibly a 2gs) to my collection. I might also be interested in a mac cube, a working IBM PC-AT (5170), or maybe more amiga hardware I don't have. For trade, I can offer up a working amiga 2000 with a hard drive (sans keyboard and mouse probably). I also have some video editing hardware that I believe is from the late 80s or early 90s. I have three giant professional JVC (iirc) VCRs, two playback and one record. I also have what I think is an abner 2 editing controller and a FOR-A FA740 time based corrector. I have no idea how to use the video editing stuff. This came out of a working video editing lab. I'm in the north suburbs of chicago. Let me know if you're interested. Maybe we can work something out. Thanks. brian

Oxidation

by chrism3667＠yahoo.com

Well there's been some discussion about this. It is possible to *charge* a surface w/an abrasive, but usually this happens as a result of 2 metal surfaces coming into somewhat vigorous contact, w/an intervening abrasive. By comparison I would have to think the adverse effects are minor, but it might be a valid concern. I would think to make tiny flecks of metal or other substance imbed in a surface, you'd have to push pretty hard. But some loose particles could catch on porous surfaces possibly, though I'm not sure they'd tend to stick there permanently. But who knows. ?I have asked how you could test a surface to see if it was charged w/particles, but thus far no answers. Perhaps some type of fine paper or plastic if rubbed on the surface would alert to the presence of icky stuff. But then again how would you distinguish that from the jagged surfaces of metal itself? --- On Mon, 1/19/09, William Donzelli <wdonzelli at gmail.com> wrote: From: William Donzelli <wdonzelli at gmail.com> Subject: Re: Oxidation To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Date: Monday, January 19, 2009, 10:22 AM -----Inline Attachment Follows----- > Steel wool?

gingerly. Fine steel wool (uh, #000 or #0000) is available at craft stores. Scotch Bright pads also. Use a lubricant, light oil (even cooking/vegatable oils), or paint thinner/mineral spirits, even water (like when you wet sand a paint job). Be careful of the refuse that will result.

xenix redux (or, how to bring back a dead xenix pc)

by brad＠heeltoe.com

This is a short story about getting data off an old xenix pc. delete now if that is not interesting :-) A while ago friend brought over an old pc which was dead. It's a 386 Compaq, very old. It had been running xenix and it was never turned off but one day the power failed. When the power came back it would not boot - the clock battery was long since dead and had lost it's disk setup. Inside is a 386 with about 4mb of ram and a Compaq ESDI controller. And a dead Dallas clock chip. I dremel tooled the Dallas clock chip and soldered in a new battery pack. I got a floppy disk image to reset the bios from someone here (thanks!) But despite many tries it would not boot. The diag program would not let me set the disk parameters exactly the way they needed to be set. most frustrating. So, I yanked the controller (ESDI), changed the jumpers and put it in another old pc which had linux on it. I booted linux and gave it the disk geometry via the command line ("hdc=1224,15,34") Once in linux I made an image of the disk using dd. It turns out that the "conv=" option is very important. I used "conv=noerrors,notrunc,sync". Originally I use "conv=noerrors" and the resulting image was bad because the disk had errors. dd conv=noerrors,notrunc,sync if=/dev/hdc of=disk.img I then put the resulting disk image on another linux box and wrote a tiny C program to search for valid sysv super blocks. It found 3. I then used "dd" to copy part of the image, with an offset (the start of the first superblock), to a new file. dd if=disk.img of=d4 bs=512 skip=2040 With that I had a valid sysv file system in a single file. I then mounted the new file using the loopback option: mount d4 /mnt -t sysv -o loop and viola! I could see all the files and could make a tar file of the root directory. Flush with success (don't you just love it when things actually work? :-) I decided to try and boot it. I used a recent copy of qemu and told it the geometry of the original disk qemu -hdachs 1000,15,34 -boot c -hda disk.img Much to my shock, it booted xenix, cleaned the file system and gave me a login prompt. Now I just have to clean up the mess in my office :-) Man that thing had a lot of dust and dirt in it. -brad

Running 3 phase 780s on single phase power (was RE: hams on

by bob＠jfcl.com

>Roy J. Tellason (rtellason at verizon.net) wrote: >Ah, THAT was the missing piece... >Now I understand what the concern is with this stuff! Right - the issue is with the original PDU, which Ian specifically said they did not rewire. That means one neutral, both inside the PDU, in the power cord, and in the power plug. The loads inside the 780 (which are single phase, as Ian said) have nothing to do with the issue. So, the 780 PDU has a three phase wye power cord (five conductors, including ground). I'm betting that they have a 220V split phase circuit to run it from, so they've wired two of the three phases together for one side of the 220V circuit, and the third phase to the other side. Best case, assuming the loads inside the 780 are balanced, that would make the neutral current the same as one of the phase currents. But that's not really a safe situation - if any of the internal loads within the 780 is turned off, disconnected, or blows its own breaker, then the neutral current will _increase_ due to the imbalance. Worst case in this situation the neutral current would be 2x normal. They probably get away with this because the PDU isn't loaded to anywhere near it's rated capacity. And let's hope they really aren't running it from three separate circuits on the same phase. Were it my 780, I'd rewire the PDU to be 220V split phase (just redistribute the third phase's outlets amongst the other two). The result would only have 2/3rds the current carrying capacity of the original, but it'd be a safe arrangement. Bob

I agree with all but the last bit, because if he's running it from three separate supplies, surely he will have three neutral conductors, so no problem.

Fujistu 600lpm band printer available

by ian_primus＠yahoo.com

I've got a superfluous 600lpm Fujitsu band printer that would like a new home. Currently located in Niskayuna, NY 12309. It's a big printer, and pretty heavy. I can get exact measurements if anyone needs them, but it's bigger than a washing machine. Wide carriage, 132 columns, and as far as I know, it works - it worked last time it was used, and probably even got a tuneup at the time. This was kept as a spare for a customer that used one. Problem is, that the customer's printer never really broke. These things are workhorses. I hate to see it get scrapped, but I just don't need it, and don't have space to store it. Give your cats a nice, humming, warm place to sleep! Adopt a line printer today! -Ian
