Seattle: Looking To Borrow Assorted Apple Gear

by ohh＠panix.com

Hey, all, especially those in Seattle with old Apple gear: Seattle Repertory Theatre is producing "The Agony And Ecstacy Of Steve Jobs", a show by Mike Daisey about Apple's and Jobs' various trials and tribulations over the years. They're hoping to put together a lobby display of several of Apple's old hardware. To that end, they're looking for gear to borrow between mid-April and late May; and to show their appreciation they're offering free tickets for the production and "your picture hanging proudly next to your relic" (assuming you're interested in that, o'course). Their wish list includes: -an Apple II, IIe and/or IIc; -an Apple III; -a Lisa; -a Mac Classic, Mac SE/30, or similar; -Macintosh Portable (1989 vintage); -an early PowerBook, preferably 100 series; -a Quadra; -Newton MessagePad; -QuickTake, an early Apple digital camera; -20th Anniversary iMac, circa 1997; -iMac G3; -an early Apple flat panel display, circa 1998-2001-ish; -Power Mac G4 cube; -G4 Powerbook; and -a NeXT workstation (though I think a NeXTcube would work too). Though they didn't list it, I have to think that an Apple I would also be extremely welcome. In fact, I think the only reason they didn't put it on their list is because actually _finding_ one seems so unlikely. :) ...Anyway, if you're in or near Seattle and have some of this gear and want to support the arts and/or get your gear displayed publicly and/or want free theatre tickets, or if you have further questions, feel free to e-mail the Rep at <info at seattlerep.org>. Feel free to forward or repost. -O.-

386 motherboard debugged, and a dead HP 16500B

by classiccmp＠philpem.me.uk

Well I certainly can't say this evening wasn't entertaining. Got the HP 16500B out of the cupboard. Powered on to a screen of random lines. Turns out the "base" (Bank0) RAM SIMM had slipped out of the mounting. Power off, all the blades out, push it back in, power on. SYSTEM SELF TEST FAILED: SEE SERVICE MANUAL System board: FAILED Touch screen: IMPAIRED Base RAM: FAILED Oh joy. Cleaning the (rather dusty) touchscreen surround sorted the touch screen. Reseating the other SIMM sorted the Sysboard failure, but the memory test kept failing. Swapped both SIMMs for a 64MB set I had kicking around -- thus giving me a 64MB HP 16500B. Powered back up, "SELF TEST PASSED, LOADING SYSTEM SOFTWARE." Now we're getting somewhere. Or not. "Corrupted LAN Board! LAN Not Functional!" So evidently the 28C16 parallel EEPROM on the 16500L LAN card has developed a case of amnesia (that's if the Random Lines Event didn't nuke it). I got to the System screen, but the 16555D isn't triggering, and trying to configure the Ethernet adapter hard-crashes the analyser. Does anyone happen to have a dump of the 28C16 EEPROM on a 16500L LAN card, or even a spare 16500H or 16500L card? Or an E2479A 16500A/B --> 16500C upgrade kit... or the bits of a 16500C needed to upgrade a 16500B... I think I'll stop there :P Apparently you need HP-specific Factory Test software to reprogram the EEPROM, which was AIUI never released outside of HP. I figure it should be possible to reprogram the chip with a couple of wires, some solder, and a 28pin turned-pin DIP socket, but I need a known-good image first. So anyway, I figured I'd try and soldier on and figure out what was wrong with the 386 motherboard. In with the POST card... yep, still dying at checkpoint code 06, which basically means the BIOS couldn't read the shutdown register in the RTC. Off with the old RTC socket, a quick clean up with Flux-off, and under the microscope it goes. I started tracing the under-chip tracks out, following them with the tip of a mechanical pencil. Until, that is, one of them crumbled... Hmm. Copper isn't supposed to do that. Out with the Xacto. Scrape off the solder resist... hmm, black fuzz, but no copper?! Apparently the battery did more damage than I thought! Eventually I found a total of three broken or damaged tracks, all on the data bus. I bridged them with Roadrunner wire (really thin enamelled copper wire, like transformer wire). In goes the new socket and.... 0d : 0c Hmm, still no go. So I pulled the RTC chip, put it dead-bug style on the desk, and started looking at the tracks again. And then I saw it, out of the corner of my eye... The VCC pin had broken off the RTC chip. So what did I do? I fixed it. I took a fresh turned-pin IC socket, and inserted a piece of 22SWG tinned copper wire into the top-right corner socket (i.e. VCC). Clipped it back to ~5mm, then put the socket to one side. Next, I used a triangular needle file to cut a notch into the plastic of the chip, right above the VCC pin stub. A bit of scratching with the Xacto got me enough Vcc pin stub to solder a wire to. Lightly tinned the VCC stub, just for good measure. RTC chip goes into the socket, and the stub was soldered to the 5mm VCC wire. Into the motherboard it goes. POST card in, speaker (on POST card) connected, power on. 0201... 0605... 0d0c... 1F1E... lots of hex numbers... 403F... *BEEP BEEP* dit-dit-dit-dit-dit-dit-dit-dit So it's just passed the chipset and base hardware tests, proven that the mainboard and chipset are alive... and emitted two beeps for a fatal error, and eight error ID beeps. Quick look up... that's a Video RAM R/W Test error, which makes sense because there kinda-sorta isn't a video card plugged in... or anything besides the POST card for that matter. It's at about this point I shouted "King of the lab!". My mother poked her head around the door and gave me a very strange look.... So yeah, the 386 board is basically fixed. I need to hunt down a case for it (the K6 board is inhabiting the 386's old case). I might chuck the thing in the dishwasher to clean off the last bits of dirt and fluff, but at this point it's working and I'm happy. Or I would be if Ye Olde HP Boat Anchor hadn't picked tonight to turn its toes up... Guess you can't win all the time :( And if you question why I call it a boat-anchor, you've obviously never tried to move a 16500B... :) Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Anyone there?

by csquared3＠tx.rr.com

This group seems strangely quiet. I hope nothing bad has happened! BTW, I realize that none of my posts are all that important. However, I do find it curious that I usually see my own posts only if someone else comments on something I said. Does anyone else have this problem and/or does anyone know of a setting I need to change to correct this? Thanks, Charlie C.

Iomega Bernoulli Box 20+20 (A220H)

by mbbrutman-cctalk＠brutman.com

I rescued one of these ancient Bernoulli boxes today. It uses the large (8") cartridges at 20MB each, and it has two slots for the cartridges. Other than for hearing some of the folklore about the drives, I don't know much about it. I'd like to see it run and be usable, but I need some help. - Is it SCSI? If so, what's the pinout on the back? It has a 37 pin female connector that I'm not familiar with if it is SCSI. - Where is the head mechanism? Is it fairly robust and protected if there are no cartridges inserted? This one has no major dents, but it has not been babied either. I don't want to waste time on it if it's just going to be a heartache. (I have enough of that already.) - Cartridges look like they are on eBay. They are cheap enough for me to experiment with. - Is there anything I should know about these beasts before I attempt powering on and working with it? Thanks, Mike

OT: high powered amps (ben)

Remember 500 watts or more will kill small rodents. > Nice! I think I will have to stay well below 1 kW though, tempting though it may be. I live in an apartment and using that kind of gear would probably a) kill the cat b) get me tarred and feathered and run out of town ;-) Jonas
