i've never had a problem cracking macs. needless to say, dont even try to use a screwdriver to seperate it at the seam; you'll only ruin the plastic! the first way is to remove all the screws and lay the mac with the tube down in your lap. put your hands around thebottom corners of the mac, and then use your thumbs to push against the DB connectors back there. since you're actually then pushing against the system board inside, that usually does it. if that doesnt work, on to step 2. for step 2, thread the top two screws in, but only a few turns. DO NOT tighten them down! use your torx bit tool or whatever, and then push or lightly hammer on your tool. by doing this, you're acutally applying pressure through the loosened screws to the front half of the mac. that usually pops it loose. you can apply the same technique to the bottom screws also. i've done this to all compact macs except for the classic and cc models since i dont own one. hope i explained it clearly. david In a message dated 98-06-27 21:57:49 EDT, john higganbotham put forth: << Also, seems that every compact mac I have messed with has already had the case popped (according to the marks). What do I do if I come across a virgin that's never been popped so to speak? Is it harder to get the case off? >>

I got an 8-year stack off mine late last year. Not because the adhesive let go though, the reflective paint on the plate did! But while I don't mind sticking that stuff on my license plates (after all, they're DMV property), I don't think I'd want to use it directly on artifacts!

Y'know, I've thought about barcode tagging a little bit, and I'm not sure how it would help, besides saving me from keying an object's item number to find the database record for this thing which I must be able to at least see, after all I can scan its barcode tag, right? > > OK, that said, the schema of my database looks something like this > [...] > > Looks good. I'll probably steal this, if you don't mind. No problem. If you have ideas for improvement feel free to share. Right now I'm thinking about whether the "notes" field should be split out into several note/memo fields for notes about relationships with other items, condition, work needing to be done, and other miscellany. That I lumped all this together in one note was part lack of knowledge about how I was going to use the note field in practice, and part architectural limitation of the in-ROM database software on the 100LX/200LX (which won't let you have more than one note field per record). > I'm a portable, wireless, and web zealot.

This would free you from the memory > constraints of your HP200LX. (Did I mention that I have some PCMCIA > wireless LAN cards available for sale or trade?) Memory constraints? Don't be fooled by that "2MB RAM" logo above the screen, this 200LX has a 32MB RAMdisk daughterboard from Times2Tech. It's like having a turbo PC/XT in the palm of my hand. I'll give you points for using k00l technology to solve your problem, but I don't think it'd work for me. Most of my collection is not stored where I live, and between the storage locations, home, work, and some of the places I go in pursuit of Stuff, I think it'd be hard to pull off a "wireless LAN". They just aren't that local, nor are they line-of-sight in any way, nor are they all inside coverage areas excepting maybe cellphone coverage. Not that I care much -- my solution is aimed at answering my decaying-neuron questions, namely "have I got any of these?", "where are they?", and "are they so screwed up that I should be looking for another example?" As it happens it also will work pretty well for answering "what's in this box?" because I've got the box's ID in the location field, so can pull up all the records with a given box ID to get my answer. Well, it'd work that way if I actually had the inventory *done*. That's the other part of the problem, I think I'm less than 1/5 there, and what is done is in several pieces that correspond to various points in the evolution of this thing. The further I go, the more I learn. -Frank McConnell

Mayday! PDP-11/44 Power supply

by kyrrin＠jps.net

Hi, folks, My PDP-11/44 has a power supply problem. Symptom: A rapid flashing of the 'DC ON' light, indicating (according to the users' guide) that one or more DC voltages is not up to spec. The kicker is that I have nothing in the way of service manual or maintenance print set. I'm kind of puzzled about why the thing died. It's been functioning perfectly well at St. Martins College for years, 24/7, without so much as a burp. The only thing I can think of is that this continuous running had one or more components stretched to their limit, and when I powered it on after over a month of power off, it pushed it over the edge. Anyway... I have no way of knowing even where to probe to see which voltage died. Even if I did manage to find it, that fscking power supply's about as complex as the CPU! If anyone's got service docs for the '44, and can help me out with some copies, that would be just grand. I'd also be open to troubleshooting via phone or E-mail. If you've got spare parts, of course, that would be ideal. I could swap modules until the bad one's isolated. ;-) This is one I really want to get working. Please give me a hand if you can. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

SE30s and IIX machines- Packet monitors and Home Automation

by thomas100＠home.com

I suppose SE30s and Mac IIs are 11 years old now! Yow. I still think of antique computers as 8-bit micros- that's just my own deluded sense of history. I bought an SE30 w/ Ethernet recently for $80 through the net. The owner showed up at my office one day recently and delivered it. The next week I also bought a Mac IIx w/ 8 megs of RAM for $25 at a Silicon Valley swap meet. A friend gave me a couple of Asante SCSI <-> Ethernet adapters which can normally be had for around $20 on eBay. I hadn't figured out much useful to do with these slower machines until... I found a very nice TCP/IP, etc packet monitor that runs on these machines. The "trial" version of this product (EtherPeek) is pretty hot in itself and is worth checking out. The full version is... unfortunately $700. I wish they'd sell the demo version with the 30-day time-bomb turned off for $100 as it's already more than what I need to monitor my cable-modem connection. Oddly... the Win32 version of EtherPeek is just so-so... I should add that in the case of SE30s, these things can sit on your desk, won't get knocked off like a laptop and are available for less than $100 with an ethernet card. This is an ideal niche machine for a packet monitor! http://www.aggroup.com - you have to download the app and then wait for the password to be e-mailed to you. ---- There was an article in the May issue of Popular Home Automation which piqued my interest in acquring these machines originally. It was entitled, "What I Did With The Mac in the Closet" and features a very vancy Macintosh/BSR controller system. This system can talk to wireless speakers in every room in the house. After taking the magazine home from the store where I found it, I realized this would be a social faux-pas in my house and decided to nix the idea. The software application that drives it is "XTension" by San Hill Engineering. It might still be fun to play with since the application is scriptable and can handle motion detectors and such. The application looks pretty nice. I wonder if the motion detectors would detect the squirrels I hear are supposed to gather from time to time in my detached garage. Hmm... The only other application I tho't of for the older Macs is as a dedicated Quick-cam machine. I must admit I use them for scanning in pictures occasionally - waiting for the images to be converted to JPEG is a hassle tho'. Thomas

Info wanted: Digital RZ23 SCSI Drive

Some of the RZ series do have a spin-up on power-up jumper, but the RZ23 isn't one of them :-( However, as someone else (Tim?) pointed out, most workstation controllers or OSs (as opposed to PC controllers/OSs) will take care of that. I have RZs on Acorn and SGI machines, but not, oddly, on any of my DEC ones. -- Pete Peter Turnbull Dept. of Computer Science University of York

Sounds like the first decent way to load Windows... Well, you typically need 4 chips, since most ROMs are 8-bit wide, and most current processors are 32-bit, but allowing a little poetic licence, Windows on a chip is possible (and Windows CE is just that). > PS-Did any computers have GUI's built in?
