  1. Self-Contained POTS System?

    That sounds like that would be what I am looking for. Outside connectivity would be a bonus but the main system needs to be self-contained. If I have, say, three computers with modems, I don't want to have to have three phone lines (i.e. $$$). And not being connected to the outside world would allow you to do stuff like dialing 555-2368 which would connect to a device that would play the Ghostbusters theme song or whatever you wanted to do. Once I had such a system, getting those computers on the Internet wouldn't be difficult. I used to offer dial-up Internet services and have the equipment for that end of things, although I would probably need to make use of the proxy setup described in the post TechEdison linked to.
  2. Self-Contained POTS System?

    Close but it looks like both of those examples rely on a connection to the outside world whereas way I'm hoping for would be fully set-contained. I have looked at Asterisk before but it just seemed that most of the documentation and tutorials focus on VoIP services and not really on how to create an internal analog phone system. I also looked at Asterisk for building an info-on-demand type system whereby you could call into the system (this time from the outside world) and, once connected, you'd enter a numerical code on the touch tone phone and a specific audio file would play. I didn't get anywhere with that idea either.
  3. Has anyone ever tried, or is it even possible, to build an analog telephone system? Not one that would connect to the outside world, but one that would be limited to your house or building. I've tried to research this before, but so much information on phone systems these days leads to VoIP systems that I've found it difficult to find info on what it would take to create something like this. The purpose would be to demonstrate (or just play around with) modems. You'd need to be able to manage telephone numbers (both for the software to understand and also to demonstrate tone dialing) and you'd have to have a dial tone and busy signals. And of course you'd get all the old modem noises. As a bonus, maybe you could make actual phone calls from one room to another. (If you've got the system, you might as well make additional use out of it.) You could have one computer running a BBS and another connecting to it as a client. You wouldn't have outside connections but this would be for demonstration and historical replication of how computers used to get online. You might also set a computer up as a server and allow older Macs (those that could use modems but didn't have networking options) to dial in and connect to the Internet via Lynx or whatever software you might have set up on the server. I would think it must be possible to build such a system. Whether it could be done economically is another matter. But it would be neat to be able to replicate the experience of the modem era.
  4. Not sure the best place to ask this but since it's not 68k or PPC or Intel specific, I figured this would be the best place to ask. Can running a PowerBook/iBook/MacBook without its screen and using the external monitor port instead damage the logic board? I seem to remember some models having issues (overheating maybe?) if you had an external monitor attached and were doing screen-intensive tasks that taxed the video system. Can't remember if that was if the displays were mirrored or what the circumstances were; I only recall there were issues of some kind. But I've not heard if running an external monitor without the internal display would cause problems, presumably because you generally wouldn't be doing that. I'm curious because I have a couple models with decaying plastics and I had thought that, since the plastics are in poor shape anyway, I might make custom cases for them. And, in cases where the screens were no longer in good condition, I would use the external monitor port to connect a display.
  5. The Mini vMac and Basilisk II emulators will both run on a Raspberry Pi.
  6. I had two pre-ADB keyboards with rubber feet in perfect shape. Now, I only have one with rubber feet in perfect shape. One was a donor model. It had a missing key, so I removed a second key from it to repair the other one which had a broken and/or missing key. The other day, I was looking through some of these old Mac peripherals and discovered this donor keyboard was stuck to the shelf it was on. Upon getting it loose, I found all four feet had melted into the wood shelf it had been sitting on. This was an unfinished wood shelf. I immediately checked the second keyboard which was kept in a metal cabinet. I figured if the feet melted on the wood shelf, the feet sitting on metal would surely be a mess as well. But that one was fine. (Although I am now storing it face down just in case.) I'm not sure why the feet would become a gooey mess on wood but not metal. Both keyboards were in the same room. The keyboard with the melted feet was closer to a window. I thought perhaps it got more sun than I anticipated, but I have some compact Macs in the same location except placed where they would get more sun. (Not on purpose--it just happened to be the only storage space available.) I'll have to check on a sunny day, but I don't believe they are in direct sunlight. Regardless, the feet on the compact Macs, which I would presume to be the same material, are fine. But they are sitting on cardboard and not directly on bare wood. Has anyone else encountered the same problem? Second question, is there a good source for replacement feet? I have grey rubber I can cut to size if need be, but if there is a source for actual matching feet that would be better, especially for a third keyboard I have that only has two good feet so needs two more for balance.
  7. ADB Wedge Mouse Variants

    My plan (one of many) has been to take photos of all the versions I have and put them somewhere as a starting point for reference and possibly for others to build on.
  8. FWIW, that's similar to the line the CRT on my Mac SE displayed until I swapped out the power supply.
  9. Mac IIci desktop publishing system

    That is a nice setup. The Macintosh IIci was the first Mac I used for work for desktop publishing. The monitor was a Radius Color Pivot Display which was pretty cool with the way it auto-adjusted the screen (long before the iPad!). It eventually began to fail and was replaced with a SuperMac monitor. I'm not sure if that was before or after Radius bought SuperMac.
  10. ADB Wedge Mouse Variants

    From mice I've seen, this version is identified as model #A9M0331. That should have read "mouse ball cover" not "mouse ball color." I have now seen two of these variants. The first is identified as model #A9M0331 and is marked as "Made in USA." The second is identified as a G5431 and is marked as "Made in Malaysia." I've seen a handful of this style and they have been marked as "Made in USA" and are identified as G5431 E119730 LR67730. I may have been wrong. I haven't been able to find an example of these made in Malaysia. The ones I've seen have been marked "Made in Taiwan" and carry the number G5431 E89826T LR66731 or just G5431 by itself.
  11. Do Mac LC III need recapping?

    I'm not an expert but I have a Mac LC III and something leaked in the immediate vicinity of the capacitors so unless an insect got inside the case and lifted its legs to relieve itself next to each of the capacitors, I suspect the capacitors may, in fact, have leaked.
  12. Glide Strips for ADB mouse?

    I thought about scanning, measuring and then cutting the shapes with a laser, but in researching online, cutting the tapes might produce carcinogenic (or other dangerous) fumes. A cutting die would be better, though much more expensive, and given that there are at least four variants of the wedge mouse with at least three different bottom styles requiring different pad shapes, that's probably not an economically sound option.
  13. ADB Wedge Mouse Variants

    Does anyone know of a site that identifies all the variants of the wedge design Apple desktop mouse? In looking through my own and also online, I've found four variants. The tops appear identical but the bottoms are different. What I suspect perhaps to be the first version has a bottom similar to the pre-ADB mice used on the Mac 128k through Mac Plus. The removable mouse ball cover is black (or dark gray) in color and twists to remove. I've only seen one of these and it was marked as "Made in USA." The next variety is the same except the mouse ball color is the same as the mouse color--not black. I've only seen a couple of these and those were also marked as being made in USA. Another variety has a mouse ball cover that matches the mouse color but doesn't twist. Instead, you push it toward the bottom of the mouse to unlock and remove it. The few I've seen of this variant were also marked as "Made in USA." The fourth variety appears to be the most common. This one has the twist cover that matches the mouse color, but is not fully round, having cut outs on the sides. These were made in Malaysia or Taiwan. I think I've also seen some of these marked as having been manufactured in the US. Anyone know of a resource with the history of these? Preferably something with a timeline. I'm thinking the general timeline maybe the order I've listed them here but I've not seen any that list a date of manufacture.
  14. Glide Strips for ADB mouse?

    FWIW, I found a discussion on this elsewhere online: http://www.overclock.net/forum/375-mice/1361172-teflon-tape-mouse-feet-replacement.html From that thread, I found these options: Hyperglides These are designed for specific mouse models, which appear to be mice typically used in gaming. They don't have any specific for Apple ADB mice, but perhaps there are ones large enough to be trimmed to size. Direct Link: http://www.hyperglide.net/ Amazon: https://www.amazon.com/s/ref=sr_nr_p_4_9?me=A3GO5VFCNOM5I7&fst=as:off&rh=p_4:Hyperglide&ie=UTF8&qid=1432704883 The remaining two options from that thread are just Teflon tape. CS Hyde Skived High Modulus PTFE with Silicone Adhesive This may be the same (or similar) tape that rickrob linked to. Amazon: https://www.amazon.com/gp/product/B004V40STO MouseTape This may be the same (or similar) Teflon tape in the previous link, but cut down to convenient strips for those that don't want to buy a full roll. Direct Link: http://www.mousetape.com/ I also came across this site, which has a wider variety of replacement feet, including ones for some of the newer Apple mice, but unfortunately nothing specific for the ADB mice though, again, perhaps some could be trimmed to size. CorePad Skatez Direct Link: http://www.corepad.com/skatez.html I haven't tried any of these yet. These are just the options I've managed to find.
  15. It probably was StuffIt Expander 5.5. It was pretty much the Swiss army knife of opening compressed files back in the day. StuffIt Expander 3.0.3 was also pretty good and had low memory requirements (384k). DiskCopy 6.3.3 will run under System 7.5.3. Not sure about earlier versions of System 7.
