Seattle Retro-Computing Society: last 2011 meeting Sat. Nov. 26th

by searetcompsoc＠gmail.com

Many thanks to whomever unclogged the backlog that, until recently, kept me from accessing cctalk or cctech. Now I can post these announcements myself! And there was much rejoicing, etc. -------- Come one, come all, to the Seattle Retro-Computing Society's monthly meeting, on Saturday, November 26th, 2011! You don't want to miss this one -- it's our last meeting until January 2012. Do you do any of the following with old computers near Seattle? + Use, collect, and/or restore them + Play games on them + Write programs for them + Develop new hardware for them + Help other people do any of the above If your answer was "yes," as I expect it will be if you're reading this near Seattle, then the SRCS is for you! We exist so you can show off your awesome stuff, bounce ideas off of fellow enthusiasts, and be inspired by one another's achievements, plans and aspirations. No idea is too big or too small, and we're not picky about what flavor of vintage machine you prefer! Come on down and tell us about it! Please note that, as it would fall on Christmas Eve and no one would attend, we will not be meeting in December. If you miss this meeting, you won't get to see everyone (and their nifty stuff) again until January. The meetings are graciously hosted by the Living Computer Museum, which is gradually fitting out a computer museum in Seattle's SODO neighborhood. There will be refreshments, a Buy-Sell-Free-Trade table, and enough table space & power to set up anything you may want to show off! For further details, please see our web page at http://www.seattleretrocomputing.com/ and our mailing list at http://groups.google.com/group/seattle-retrocomp . Hope to see you there!

Anyone with Cipher F880 experience?

by fraveydank＠gmail.com

I have a DEC TS05 (re-badged F880 without high-density mode; otherwise same PCB and everything) which is poorly behaved. Before I go diving in with the maintenance manual, is there anyone on here with experience repairing F880s? Symptoms: - It occasionally just resets (especially once it gets warmer). I'm willing to bet this is a flaky regulator somewhere, but I don't have a digital scope to see the transients very well. - When loading (and occasionally during operation, if it ever gets that far), it bugs out with either a compliance arm or tachometer error. Both of the superficial diagnostics for the compliance arm and the tachometer indicate no problems, so I'm assuming it's a problem somewhere in the logic. It only successfully loads maybe one time out of 20, even when I load it pre-threaded (1 out of 3 when it's cold, but it doesn't stay that way for long), which makes the first problem all the more irritating. - Dave

Got any data to back that up? Been to any universities lately? Read many research papers? I do all the time, and most are done in LaTeX.

Xeltek algorithm generator?

by fraveydank＠gmail.com

Someone mentioned something about a Xeltek algorithm generator a while back. Any idea how that one works? The NMC9306 algorithm seems to be non-functional even for a tube of 9306s that seem to work fine in their target device (the aforementioned CQD-220). Looking at it in a hex editor, the algorithms appear to be PE (either executables or libraries), and IDA brings them in OK, but I'm not in the mood to reverse engineer more 8086 code to fix this stupid ROM burner. Worst case, maybe I'll build a quick and dirty 9306 communicator on my DE1. :-) I already have a perfectly functional UART peek/poke unit. - Dave

(OT) SmartMedia un-erasing - help?

by mtapley＠swri.edu

Joe P., thanks for the pointer to digital image recovery! I'll find a Windows machine and try it if I can't work the problem with my Mac. ----- John F, DigitalForensics will also get a shot when/if I start seeing bits of files recovered. That's not looking so likely, though. ----- At 19:31 -0600 11/17/11, Ian wrote: >Not that I've ever accidentally deleted files from a camera card. No. Never. You have my sympathy and thanks! What was on my card would have been all .jpg compressed images, so Photorec looks perfect. ------ At 19:31 -0600 11/17/11, Ian and Mouse pretty much chorused: >You need to specify the device itself, not the mountpoint. Type >mount to get a list of all the devices that are currently mounted, >and see which one corresponds to the /Volumes/Untitled mountpoint. >Unmount it from the command line, then use dd to copy it to a file. Ah! mtapley-3:~ mtapley$ mount ... /dev/disk1s1 on /Volumes/Untitled (local, nodev, nosuid) mtapley-3:~ mtapley$ su root ... mtapley-3:/Users/mtapley root# umount /dev/disk1s1 mtapley-3:/Users/mtapley root# dd if=/dev/disk1s1 of=PhotosToSort/LostCard/ddClone128M.dd conv=noerror,sync 255953+0 records in 255953+0 records out 131047936 bytes transferred in 153.810460 secs (852009 bytes/sec) The naive shortcut to /Volumes just got me a symlink or something? I'm embarrassed to admit I had to hit more man pages to remember that unmount is spelled umount. Anyway the dd command chugged for several minutes.... ...at the end of which, I got another image which was composed almost entirely of "FF" pairs, according to OxED. Near the start, there is, as in the other images, "FAT16", some stuff that says "DCIM" and "Trashes", "100OLYMP", a "Mac OS X" string, a "This resource fork intentionally left blank " string, and a few other short (10's of bytes) bits of stuff in mostly 00 areas. After that, just an ocean of FF pairs. Not surprisingly, Photorec finds nothing. Likewise for Exif-U. 0 files saved in /Users/mtapley/Applications/testdisk-6.13/recup_dir directory. Recovery completed. Although I'm willing to go on and try other tools if people want, I've become a tad discouraged at this point. Am I right to be so? It looks to me like the camera re-initialized the card and wrote all FF, ready to be recorded on, and if Mouse is correct that's pretty much that. Even for the cool Yellowstone photos, I'm not willing to pay for an AFM image of the flash memory. Cheaper to round up the family and go back to Yellowstone. Any further suggestions? Expecting none, I still want to offer most heartfelt thanks to everyone for their pointers and tips. If *this* group can't help me, it's a testament to how well and truly I managed to screw myself. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.
