Re: Vintage Mac Recommendation
others are much better informed on this subject. But the h/d will be compatible - physically - with virtually every Mac made. Assuming it's a 3 1/2 model (it has to be I reckon). As to absolute os compatibility, well it shouldn't go so bad. A few tweaks will be necessary I'm sure. I personally have never operated a Mac w/more then 1 h/disk. You can have 7 drives daisy chained on 1 scsi channel. They have scsi in the rear. You could consider simply using your drive as an external unit. Why are you being such a pansy and don't want to install in os fresh? To ensure the safety of your data, you may want to install your drive as secondary. Who knows, something could go wrong . . . The quintessential old school Mac is the IIfx IMHO. If you wanted my opinion on something newer, the Color Classic or LC475 (Quadra 475?). In any event the Mystic mobo drops into both machines. And with the CC, you have your monitor built in. O man you are in fact the quintessential Mac user.

Re: IIcx Motherboard Damaged Traces?
all good advice (bear in mind I'm no expert though). But what about vinegar and maybe salt to clean the surface of the board? It eats green oxidation. There must be other chemicals/substances out there that will consume battery acid and corrosion. Baking soda and or vinegar? Wes, you can make a new trace if you want to. In my opinion it may make more sense to solder the trace to it's respective points, and forego epoxying until later. You may even be able to get away without it. Just to see if it works. And you can get some thin hookup wire and use that to determine if that's the problem. Just use a small bit of solder clipped from a roll (I have some very thin kester no lead solder in my stash), and a not iron to just tack it in place. Heck you could mechanically short the 2 points together with an all metal compass say or a bent up paper clip (no it's not really a short, that's just a way of saying you're connecting 2 points together with a conductor. Be careful not to actually short anything). Keep in mind also that sometimes these pads have an opposing pad on the bottom of the board. You can use that point, if present, to confirm continuity or lack thereof. From: Derek Morton thes...@comcast.net To: vintage-macs@googlegroups.com Sent: Saturday, August 15, 2015 7:53 AM Subject: Re: IIcx Motherboard Damaged Traces? Wesley, Continuity is the key, if your meter is indicating an open then the traces must be bad. To verify, I would suggest cleaning the area with isopropyl alcohol first (99% if you can find it otherwise the highest number you can get). Use an acid brush (http://www.homedepot.com/p/Oatey-1-2-in-x-6-in-Acid-Brush-307122/100346943) which has been trimmed to give you a shorter angled brush head (cut off around half the length of the brush). This will give you a good vertical scrubber which won't be overly harsh on the surface and will tolerate the chemical environment. Scrub firmly, but gently... Too much force can cause damage. After scrubbing you need to clean up the area before the alcohol dries. The alcohol (in conjunction with the scrubbing) will dissolve and lift the contaminates from the board but when it evaporates the contaminates will be re-deposited on the board. Ideally you should use Kimwipes to clean up the area, but a thin cotton cloth (old t-shirt perhaps) should work reasonably well. Verify the continuity (or lack of) once cleaned. You can fix the problem in a couple different ways. The proper way is to remove and replace the track. This is a moderately difficult task requiring you to remove the damaged track, cut a new track from copper sheet to replace the damaged section, epoxy it to the board (feathering in the points where the new trace meets up with the told trace), solder the ends to re-establish continuity and then coat with new track to protect it. The MUCH easier option is to simply use some hook-up wire to bypass the damaged section. You can go from via/pad/track to via/pad/track, take your pick. I would advise some caution however. Apple's boards do not seem to tolerate re-work well. Everything seems to lift from the board with very little heat, so be careful.

Take a look here: http://www.megley.com/temp/iicx.jpg The white square lines at the bottom are where C7 sits. My meter is not getting continuity between the upper pad on C7 and the spot just above and to the right of it. The other trace that goes from the left of it to above it looks bad and I'm not getting continuity there either...but I don't know how much of that might just be the crud on those points. What do the experts think? Likely bad? How does one go about repairing those traces if they are bad? Can the points (are they vias?) be cleaned up and soldered to?

Re: Monitor
It's not about the size of the monitor, it's about resolution. Many macs can support different resolution, from 640 x 480 up. I do not have any more of this data handy unfortunately. You need to, iirc, short certain pins together for it to boot into a certain resolution. There should be a diagram or data somewhere. I routinely used to make these, in the mid 90s, to support single resolution fixed frequency monitors that I would find on the surplus market and sell them to Mac users. I still have a couple HP/Sony units tucked away. Don't just start experimenting. You need to either buy a dongle or a cable (that has the pins already configured). I have a few Sony dongles in storage, but on one side they plug into a 15 pin Apple card/connector, a VGA cable on the other side. Probably not what the op is looking for. -- -- - You received this message because you are a member of the Vintage Macs group.

Re: Horizontal line on screen
you can simply remove a board, and touch each connection (on the bottom, solder side) with a hot iron. I fixed a power supply like that once. Will the operator be subject to discharge from a capacitor? Not if you avoid those altogether. Soldering iron handles are plastic anyway. You could also ground the iron w/a strap. Discharging caps and tubes is no big deal though. Just short each lead to ground through a suitable sized resistor (resistance and power). There will be numerous details on the around the net.

Re: Removing pry marks from a Mac 512K case?
Well you could drill an appropriate sized hole in a suitable material and use a heat gun to soften a localized area. Touchy work. Far more of an art then science. You could practice a bit on an inconspicuous area. Say the inside of the keyboard. But there's no grainy texture there. -- -- - You received this message because you are a member of the Vintage Macs group.

I can't see any corrosion. That isn't much of a computer. Looks like a few ttl chips. Most cars of that age have 2 computers afaik.

Re: hello guys, Hey upgraded LISA I question.
Maybe a complete board but not individual transistors. This is an easy fix, after you get the boards out. Static could be a hazard if you're not using a proper desoldering station. I don't own one, and would and have replaced individual components on circuit boards successfully. Just grasp the old component (or lead if the component is cooked) with skinny pliars, heat both leads with say a 15-25 watt iron, either simultaneously or go back and forth quickly, and pull. Hopefully on exit the leads will leave holes for reinserting the new parts. If not just heat the area/pads, but just enough to make the solder flow, don't cook the board, you could create more problems. Then reinsert the new components and add a bit of solder while applying the iron, and that should do it. -- On Fri, May 3, 2013 3:45 PM PDT Richard Darner wrote: Check with vintagemicros via eBay.

Can anyone look at their lisa cpu board and let me know what you have in that spot? Thank You!

From the picture it's not altogether clear that transistors Q1 and Q2 are supposed to be the same type.. A pretty common circuit uses PNP and NPN pairs close together. The pair to the 2N2907 is NPN type 2N, also very common. (I have a bunch of both here. Use dmcnutt at above off list with Lisa somewhere in the subject.) A look at a working Lisa would be worth while. Anybody here ?? I also have no idea what the A in front of the very common Motorola MPS means. -- Fe++ // \ Fe++ Fe++ | || Fe++ Fe++ \\/ Fe++ -- -- - You received this message because you are a member of the Vintage Macs group.
