If you turn on file sharing, select the hard drive icon, go to the finder File menu and select Sharing..., hopefully the item on the top "Where:" line is your hard drive name, not the dreaded Q250. Select (click the empty x box) Share this item and it's contents then unselect the x box. Does...

More info on the HP-35 at http://www.hpmuseum.org/hp35.htm . Also, there is a product introduction writeup in the June 1972 issue of the Hewlett Packard Journal, available online from HP (caution, 4.6 MB pdf download) at http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1972-06.pdf .

Okay, while cooking dinner I sucked in 1 MB and looked at it. I notice you have solid blacks and solid whites with no pixel light leakage at all visible in the Jigsaw and Key Caps icons. This suggests the other gridding could be a dither/shading/rendering choice on lightly colored areas, could...

Please pardon my ignoring the pics and not commenting, the recent storm thru the SF bay area took out my Sunnyvale wireless ISP; zero WiFi beacon from the neighborhood lightpole antenna, so I am left sucking thru a dialup 28Kbps straw similar to funkytoad's situation [:(!] !]'>

Depends on whether the particular LCD uses a black masking matrix everywhere but over the pixels. If it does, only the pixels can light up, and a grid pattern around all good pixels is impossible, only pixels misbehaving in vertical and horizontal patterns surrounding apparent good pixels but...

Byrd's idea sounds good to me. It's been a while since I took one apart but I think there is a thick semi clear plastic light spreader panel, a thin plastic diffuser sheet, a thin plastic polarizer, then the LCD guts, from back to front. That polarizer sheet needs to be at the correct angle...

Never had to order one. If they will not send one engineering evaluation and qualification sample part to your chief engineer, you might have to procure a parts board and salvage a filter. According to the Guide to the Macintosh Family Hardware Second Edition, the SE, SE/30, II, IIx IIcx, and...

Just for example, D1 and D2 are both diodes in the SOT-23 package, manufacturer's package marking 5D. Investigating this part marking code, http://www.tkb-4u.com/code/smdcode/smdcode5.php indicates that Zetex FMMD914, and Motorola MMBD914 both have the appropriate basing diagram. This is...

Indeed, it all makes sense, Pin 1 is the Pixel clock, and presumably that multiaperature ferrite core thingy is of low enough permeability and loss to just take a bit off the edge of the clock for EMI radiation interference control without destroying clock function altogether... [:)] ]'>

If you can, please identify exactly which number IC pin (or marked up photo please) that white wire once connected on UG6, and also if that wire was a single conductor or a really skinny shielded conductor. Judging from the number of pins on that connector, it not only had DC power, but also...

Hmmm, both my PB540c units running 7.6.1 that I tried do this, a brief flash just as you depress the select function over the battery monitor. But there's more! If you bring up Key Caps, you will see that caps mode is not being even briefly selected. Still more...manually press Caps Lock...

What, me worry? Slowly, slowly, the charge on the floating gates of the EPROM (SE/30 Video ROM) is leaking away. A backup of the ROM contents would be good. A very small fraction of devices would fail in the 20 year design life originally targeted by Intel (described in Electronics, Aug 14...

Just one, see page 8, http://manuals.info.apple.com/Apple_Support_Area/Manuals/printers/0306992AACSW2200SU.PDF

Should not be a problem as long as the cells contact the heat spreader with no more insulation thickness than the existing cells' sleeving. The batteries run and charge cool until the very completion of charge when the cells start to get quite warm. The power manager is looking for this temp...

I have disassembled one PB1400 battery pack and it contained eight Sanyo Twincell NiMH cells of size 4/3FAU (unsleeved measurements, excluding tab thickness were 66.7mm L x 17.4mm D). In the US, Digi-Key part number SY136T-ND for the solder tabbed version. But these are expensive as in $10.88...

Hey, nothing is a really, really good price! Good luck with that smoker's machine, I recommend a spray bottle of ethanol (denatured alcohol), and lots of wipes, that smoke gets everywhere, even under ICs! You can get rid of a lot of ash and tar buildup if you start with the fan, but to really...

I got an IBM WorkPad c3 for $4. It's the IBM version of the Palm Pilot V series, I think. It has just 2MB, grayscale display and internal rechargeable battery, I charged it up and it seems to work fine. Had to use Goo Gone to remove adhesive residue that covered the entire backside, but it...

Yes, indeed, quite possibly the very same one you saw! I bought it from WeirdStuff right after I finished shopping at the nearby Computer Recycling Center. [8D]

So Saturday I buy a PowerBook 540c with a battered keyboard and broken hinge for $5, hoping it has a good display that I can use to replace another that is failing. I get it home and find the hard drive has been pulled, so I install another and bring up 7.6.1. The display is bright and clear...
