  1. Hey all - Does the PRAM battery in the G3 Wallstreets pose an existential threat to the machine like the PRAM battery in the 3400c and other machines? Based on where and how Apple buried it, it doesn't seem like any leakage would affect the innards of the machine (so long as it was left laying flat), but I was wondering if anyone had experiences with this.

    Apple /// Problems

    Anchor Electronics in the South San Francisco Bay area has 4164 RAM chips, but I don't know what, if any, difference there are between those and D4164C chips. http://anchor-electronics.com/price-list.pdf Where are you located? I have a 5V RAM board from my spare (re: board needs to be recapped) Apple III. Before I blew a capacitor on that board, the machine worked just fine. If you are somewhat close, I could lend you the RAM board and see if you get any different results.

    030 powered 512k, thoughts on maker?

    Someone in the Monterey, CA area is selling a 128k with a "Gemini" 020/030 processor upgrade -- there aren't any pictures of the inside, but I guess there was at least one company called "Gemini" that made such an upgrade? https://monterey.craigslist.org/sys/5928855151.html

    My friend was also, apparently, a very active member of BMUG and was responsible for putting together their CDs. He gave me copies of a 1995, 1996, and 1997 BMUG CD. No idea what is on these -- will have to check them out!

    A friend of mine who found out I was a fan of older Apple products gave me a stack of Post-It -type notes in the form of the Mac! He says he got this at an Apple event in the early 80s.

    Powerbook 180 Battery/Power Issue

    Has anyone had any experience using these third-party adapters with their older Powerbooks? They say they are compatible with a 180, but I figured I would see what you all think: https://www.amazon.com/Hi-Capacity-Adapter-Apple-PowerBook-M5140/dp/B0000X6CQ8 https://www.amazon.com/EPtech-Notebook-Adapter-MacIntosh-PowerBook/dp/B01CAGZN3A http://www.kahlon.com/itemdetailpg.asp?itemid=253304 Thanks!
  7. I pulled out my Powerbook 180 for the first time since I moved (several months) and fired it up. I have a new battery I bought not too long ago, so it holds a charge pretty well. The machine fired up and was working fine. After a bit, I got a message saying "Your battery is not charging. Check the power adapter and electrical outlet connections." The machine is definitely plugged into a good AC outlet and the adapter is definitely plugged in. When the machine is on, the battery application indicates the battery is being charged, but at the same time the machine is giving the flashing battery warning in the top left. The battery drains and the machine shuts off; it won't start up without a charged battery installed. I tried resetting the power manager (by removing the battery/power adapter for 3 minutes and then pressing the two recessed buttons for c. 30 seconds), but no dice. I am guessing the adapter died? Has anyone else seen this issue before and had it be something else other than the adapter? If it is the adapter, does anyone here have the skill to recap/repair these and want to make some money?

    Finding replacement 6502 for AppleII+

    Did the 6502B just have a faster clock speed from the original 6502?

    Mac Portable back up and running!

    I wonder re: the trackball. Since it seems the rubber rollers start to go after a bit (causing it to be unable to move the cursor in a given direction very well/at all) -- couldn't someone get a 3d printer to create little plastic rollers to replace them?
  10. So I received a ReactiveMicro Universal PSU unit today for my Apple III. ‚ÄčThe instructions for installing/wiring it are here: http://reactivemicro.com/w/images/2/2a/2016-11-07_-_ReActiveMicro_-_Universal_PSU_Kit_-_Install_Instructions.pdf The Apple III instructions begin at p.46. I have installed everything without problem, except that instead of a "black or brown" wire and a "white or blue" cable, I got two blue cables -- one with a "female" connector that connects to the back of the power switch, and one a pin connector that connects to a wire coming out the back of the AC outlet. The instructions and pictures at step 10 are therefore not clear to me: Which wire is "hot" and which is "neutral"? Should the blue wire connecting directly to the power switch go into "slot 1" of the MTA156 connector (closest to the large capacitor) or should it go into "slot 3" (i.e. the middle one)? Does which connector it goes into determine whether the wire is "hot" or "neutral"? I emailed ReactiveMicro, but they probably wont get back to me until tomorrow. I figured maybe someone here with wiring experience would know the answer tonight!
  11. Oh, also: What is the difference between the A3S1 and A3S2? The bottom of the A3S2 says it has 256k of RAM. The bottom of the A3S1 says 128k of RAM, but the diagnostic said it has 256k of RAM. Both seem to have a "5v" RAM card installed above the motherboard, so maybe the original owner upgraded it?
  12. So this week I got quite the Apple III haul -- Two Apple IIIs, an external Disk III, 2 Monitor IIIs, a Profile HD, and a silentype printer, and a Titan "III to IIe" emulation card for a combined $150. I also got some Apple II related stuff for like $30 extra. One Apple III seems to have some issues -- It will turn on and the speaker will make a little "put put" sound, but the disks won't spin up and nothing appears on the screen. The other Apple III appeared to be better (would spin up looking for a disk and display "Retry" on the monitor). However, when using it, I smelled something off, like burnt capacitors. I removed the PS and, sure enough, it looks like long ago a capacitor went. I sent the PS off to Uniserver to be recapped, and I will definitely keep it as an example of the "original" PS, but I think for my actual usage I will get UltimateMicro's "Universal" PSU kit. Fast forward to this evening, though. I wanted to generally test the system, and I am an impatient person, so I didn't want to wait for the recapped PS or the new Universal PS kit. SO I opened the PS on the "broken" Apple III (the one that doesn't do anything). In that PS, all the caps looked good (and that PS is slightly newer, coming from an A3S2 machine rather than the other one which is from an A3S1 machine). So I threw that PS into the "working" Apple III. I made a diagnostic disk via ADTPro on my IIc and it worked (see attached picture)! I ran the diag program for about 15-20 minutes Then I started smelling something. I looked behind the machine and saw smoke wafting out the AC outlet. I shut the machine off and unplugged it. After the smoke cleared (literally), I opened the PS and *the same capacitor* that went off on the first PS had now blown. Lesson learned. I can wait for the Universal PSU kit, lol. I had a couple of questions relating to my experiences so far: (1) The Apple III that only went "putt putt" -- Anyone know what symptoms might suggest? Since the PS was literally minutes away from going, is it possible it was a PS issue and that system was more vulnerable to it? Neither machines had a card in any slot. (2) On the working Apple III, when I first put the diag. disk in it, the drive would spin the disk up, but ultimately not load anything, invariably going to the "Retry" prompt. When I got the machine, the disk door was slightly askew. I wonder if the head or something got out of alignment. Are these things reparable? If so, do you know anyone who repairs DIsk IIIs? Ultimately, I swapped the internal disk drive out of the "broken" Apple III and put it in the "working" Apple III and it loaded the disk no problem. (3) The working Apple III was working fine *as the PS was smoking.* I shut it off within 10 seconds of "smelling" something wrong. Is there a major risk that I have damaged any component inside the machine?
  13. So I acquired additional Apple III-related goods today from the same Craigslist source, including a Monitor III. This Monitor III has a badge that is like glued to the front that reads "Apple Computer Inc: 1082" (see picture below). Has anyone seen badges like this before? Is this a sign it was used internally by Apple workers? I note that this Monitor III has what *seems* to be a low serial number (its 4 digits and dated May 1981 -- there was another Monitor III I left since it looked like it was in rough condition that was dated December 1980 and had a 3 digit serial number).

    This one on eBay seems to have the same chip missing as nine: http://www.ebay.com/itm/Rare-Apple-III-Titan-III-to-IIe-Board-Set-see-pics-/152295987768?hash=item23758c5a38:g:DusAAOSw44BYEhhh
