Real Hackers, tools of the trade (was Re: Vector Graphic range...)

There were 2 sizes of reamers and only one now is the primary one that comes to mind. The one I use the most is the one they discontinued - of course since mine is dull. >>'Tamperproof' Torx drivers are almost essential if you work on SMPSUs >(many manufacturers seem to like them).

LT33?

by healyzh＠aracnet.com

I'm looking at the required hardware listed on a SPD I got today, and it lists a "LT33 terminal with low speed paper tape reader". Is that the same thing as a ASR33? Zane | Zane H.

Kits vs ready-made (was RE: Rebirth of IMSAI)

by allisonp＠world.std.com

<What I do if I can stand the stray capacitance (and I often can) is take <a piece of copperclad for the groundplane. I then stick (double-sided <tape is strong enough) little 'islands' of stripboard, track side up onto <the groundplane. Solder the ICs to the stripboard. Then solder the ground <wires from the strips to the groundplane (as short as possible). That <will anchor the stripboard in place. Decoupling caps go from the power <strip straight to the groundplane, etc. That happens to be an effective way to do it. Works well for RF too. As to proto, I have a few peices of equipment that were deliberately built that way with over 15years on them. With a little care it can be very rugged. Allison

Of >course I'd rather have the set the size of a small suitcase! I have found that the 99MP is good as a starting base and then add the rest. In the toolbox that I use every day I think there is every 99 series tool that is avail. There are also some that they don't make anymore. Also you need to check out the security bit sets that Jensen offers. They have the most complete set I have found. Dan

New uses for old toys!

by DSEAGRAV＠toad.xkl.com

My boss has come up with a good use for all my old toys! We're an ISP here, and I play BOFH. So, we're moving to a new building, and all the customers are wanting to see our internet toys when they sign up. So, the new machine room is being constructed as follows: 1. It'a a large room, raised flooring, and it has an observation window. The idiots can look thru the window, but not come in the door. 2. The room is also decently air-conditioned. It'll (obviously!) have fast 'net access. Meaning: 3. We aim to get our hands on all the boxes we can with flashing lights or interesting buttons on the panels. These will be visible from the window. All the real gear will be on the other side of the room. Basically, this means all my boxen get a fast 'net wire, and a nice room to live in. All they need to be able to do is look complicated and/or impressive. Is this sort of thing legal? Sounds too good to be true to me... -------

Sorry, no offense, but "its the name". ( seeing the "RESCUE" i saw already one of this SAR helicopters around my head ;-)) I just was on your site, and this is probably exactly what i tried to do. I would only suggest, to put the "collector" somewhere in the name. thanks a lot for your work, emanuel

H740 Bridge Rectifier

by mcquiggi＠sfu.ca

Hi Allison: I have the schematic in front of me, mechanical drawing too. It's on my web site if you _really_ need it after this, or send me your fax number and I'll get it to you that way. Looking at the mechanical drawing, if you look at the rear of the 8/f, with the H740 installed, the bridge rectifier is at the top, right hand side of the supply, above the large heat sink fins, to the right of two large transistors. Ascii art for pin orientation: (top edge of board, as you face component side with H740 installed) --------- | + AC| (Large Trans) (Large Trans) | | |AC -| --------- ----------------------------------------------------------- ----------------------------------------------------------- (Heat Sink Fins) ----------------------------------------------------------- ----------------------------------------------------------- (Large Trans) (Large Trans) (Large Trans) (Round connector) (bottom edge of board) The rectifier is labelled only "NSS3514", no ratings indicated in the specs, just "bridge rectifier". Input is 28VAC. Good luck, Kevin --- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

Help finding software for Nicolet NPC-764 logic analyzer (8085 CP/M)

by jlewczyk＠his.com

I recently obtained an old Nicolett NPC-764, which is a CP/M machine (8085 based) with a built in Logic Analyzer, with software for the logic analyzer built into ROM. Its a "luggable" computer (which means that they put a handle on it and bolted down all the boards ;-). One thing I do not have is any 5 1/4" floppy disks for it. Therefore I can't boot CP/M and I don't have any of the software that came with the unit to assist in using the logic analyzer. Do have any idea on how I could get some of this software? Nicolet hasn't been any help. Thanks!

Looking for 8008 language software (PL/M, MASM, BASIC,...)

by jlewczyk＠his.com

Hi. I'm new to the list and this is my first posting. I am looking for PL/M cross compiler that Intel produced for the 8008 CPU. I have the Intel manual, but no source or object for the language compiler, which was written in Fortran by Gary Kildall when he worked for Intel back in ~1973. I have source for an 8080 version of PL/M from Intel which went into the public domain at some time, but I do not believe that it will produce 8008 code (that ability is not mentioned in the documentation). Any help or information on this would be appreciated. Also, a macro assembler or a basic interpreter would also be appreciated! Anything would be better than hand assembling and jamming in bytes via switches. Thanks, John - John Lewczyk - IO Consulting - 401 Queens Row Street - Herndon, Virginia 20170-3131 - jlewczyk(a)his.com
