Kaypro 10 Western Digital Hard Disk Controller WD 1002-HD0

by james＠slor.net

Richard - I found your name in an old post referencing the 1002-HDO controller, and I was wondering if you have any information on how to do a low level format with it. I have been looking for a while to get my Kaypro 16 up and running, but I have not had any luck. Is it hiding from me in the controller rom? Do I need an external program? If you have any info, I'd most appreciate any pointers. If you still have the scans of the datasheet/manual, I'd love to get ahold of them as well. Thanks! -- James

Wofford Witch usage

by wacarder＠earthlink.net

Here are the LOGICAL names for the various public directories on the WITCH: GAME: = DK2:& = GAMES SOC: = DK2:$ = SOCIOLOGY MISC: = DK2:! = MISCELLANEOUS CS: = DK2:% = COMPUTER SCIENCE STAT: = DK3:$ = STATISTICS ECO: = DK3:! = ECONOMICS MATH: = DK3:% = MATH SCI: = DK3:& = SCIENCE I also thought that I had a logical LU: for Local Utilities, but I must have missed that. LU: should be mapped to DK2:(1,13). I have just added LU: as a LOGICAL and it will be available until the system goes down or until I make it permanent.

Wofford Witch usage

by wacarder＠earthlink.net

I notice quite a bit of activity lately on my online Wofford Witch system. If anyone has any questions about how to get around on the system, feel free to email me or to leave a message on the Wofford Witch web site. I have quite a few 1970s vintage games loaded on the system. If you log in and would like to see what games are available, you can type: DIR GAME: to get a directory listing. If any of you are serious about learning how to use the system and would like your own account instead of my guest (40,1) account, send me an email or post a message on my message board. Basic information on how to use the system can be found on the web site under Witch Documents in the Witch User Guide. This guide actually was for the original Witch back in the 1970s, but much of it applies to the Witch that I operate online via my web site. Thanks and enjoy!

making room... cleaning out stuff

by tomj＠wps.com

Hey, long time no C... about 6 months. So unbelievably swamped with work I just had to drop time-sucking side shows I mean side projects... :-) Part of recovery from 2005 is making room in my smaller lab for the future, so cherished but in-the-way items must go. * I'm reducing my Data General Nova/4 to one rack. 'Must go' are a D.G. 6xxx vacuum column tape drive (or two) in good working order; the 4300 I/O subsystem with SAM and software; and depending on Bruce Ray's choice on first refusal, my Dasher LP2 in perfect working order, with a case and a half of sealed new factory ribbons and one case of greenbar. Centronics interface (plug onto a peecee!). Not easy to ship the latter. All in excellent shape with complete paper documentation and software. Would trade it all for one compatible reel and arm type tape drive that'd do 1600 bpi (would then free up the 2nd vaccuum column drive too). The items below are on eBay now: * bunch of S100 cards, all cheap and with manuals. * DSI paper & mylar punch and reader (broken hinge on reader but otherwise 100% fine). * HP 1650b logic analyzer with 5 complete probe sets. Works perfectly, tube somewhat dim. No operating manual, have maint. manual. ian * Old Shugart 801, w/front panel UNIT and WRITE PROTECT switches. * Kaypro II, very clean, in factory nylon carrying case. * Cardmatic 123a, with bunch of cards, non-working (bad tube and linecord for starters) but very clean * Micromation 10-slot S100 buss & card cage.

cleaning keyboards in the dishwasher

Most likely that's down to electrolytic action between slightly different metals, particularly where utensils are touching each other. It's commonly seen with mixtures of "stainless" steel. It's not because of the type of detergent. -- Pete Peter Turnbull Network Manager University of York

I was oversimplifiying, I admit; there is a difference, yes. It's not an area I could claim to be a real expert on, though. -- Pete Peter Turnbull Network Manager University of York

shipping for monitors

by legalize＠xmission.com

OK, I have had terminals shipped to me in the past and they were fine, but I experienced a bit of damage when having a Heath Z-19 terminal shipped to me recently. Fortunately it can be repaired, but I think its just that I came out somewhat lucky (even more lucky would for it to not have been damaged at all). If you were to ship a terminal/monitor, what would be your approach? In the case of the Z-19, I think the root cause is that only 1 of the 4 mounting screws for the tube in the case had a support bracket. This is the only mounting post that didn't shear from the rest of the enclosure. The other 3 posts sheared off at their base to the enclosure. Some superglue should be able to reattach the posts to the enclosure so that the whole thing will be "like new". So this might be something specific to this enclosure design. However, I'm currently looking at a Tektronix 4115 that's in Illinois and I'm in Utah. This is an item that would be "key" for my graphics collection (and I've not seen one offered with any great frequency; a local supplier has them but he charges $1200 minimum for these units as costly replacements for mission critical systems). However, I'm really leary of shipping it that far after my experience with the Z-19.
