    Few Random finds from abandoned building

    Aside from the Classic II that CD drive strikes me as the most useful/valuable thing there. Plenty of Macitntosh computers that came out prior to the mid-1990s (1995?) came without a CD drive, the ones that did are some variant of 2x/4x/8x and far from 24x, and some later models didn't yet have one by default (optional).

    6100 Sonnet sticker location.

    Agreed. I think it could make bigger difference than you'd think at first because most people would have had stock configurations at lower speeds with less ram. So presumably most of the software of the time was developed with those lower specs as the target. As a consequence it may well be that most everything runs better with the extra headroom in the CPU (and maybe RAM) department. It seems like today's developers may be targeting the upper end more often that not leaving people with older/slower hardware in the absolute last place...

    Heh. I wouldn't mind one myself. My Power Mac 6100/66 has a Sonnet G3 250 MHz installed (not quite as fancy, but still much faster than stock).
  4. IDK about the LCI/II/III as I never got the card I have working on my LCII beyond maybe installing the drivers and a green light of some sort. But I will note that I had similar trouble with my Power Mac 6100/66 not playing nice with a more modern 10/100 Mbps (Fast Ethernet) switch or hub, whereas interposing a 10 Mbps hub in between it and more modern hardware solved that problem (probably a similar auto-negotiation/duplex problem).
  5. I wouldn't necessary rule out sudden failure of some critical PSU component, these machines are 25 years old after all. A multimeter is okay for simple voltage, resistance, and continuity checks, but not generally useful for determining if capacitors are dead (at least not while they're in-circuit) or the overall health. IDK if there are any good test points, but it wouldn't be a bad idea to verify that the inputs/outputs of the regulators seem as expected and that where the electricity enters the board the voltage also seem correct. Also capacitors don't have to look bad or be leaking to be dead/out of spec, or at least that's my understanding. Does it matter whether you leave the battery out or not? P.S. I really doubt it matters here, but compressed air is pretty cold coming out.
  6. Perhaps your problem has mostly to do with cable select... https://en.wikipedia.org/wiki/Parallel_ATA#Cable_select

    LC 1 vs 2 vs 3

    I swapped an LCIII board into a LCII case several years ago and I don't recall there being any problems with that. FWIW I want to say there's enough spare room that the board's shorter clearance to the fan isn't a physical issue (the fan is held in by clips to the left and right relative to the above pictures). Presumable the other direction (LCII board -> LCIII case) is also amenable, given that the boards are essentially the same in dimensions and components as well as the side notches. You know excepting the spacing difference near the fan which shouldn't be an issue as the LCIII case has space for the fan and the LCII boards leaves more room, not less. you can see the extra space near the fan here: https://ancientelectronics.wordpress.com/2017/10/12/macintosh-lc-ii/ My guess would be that you could probably migrate a Macintosh LC board forwards with some caveats relative to hooking up various components and a LCII might fit into the LC chassis. It does look like from the below page that the LC had a larger fan+surround design that might not permit fitting the LCIII board, though and the total lack of the edge connectors might be a problem. https://ancientelectronics.wordpress.com/2017/09/28/macintosh-lc/ P.S. It's also worth noting that the PSU connector moved from the LCII board to the LCIII version IMHO it's a bit of a tight stretch, but plugging the LCII's PSU worked okay.
  8. Wow. Talk about a fancy setup! Hate to think about how much all that would have cost back then.. Any time I see stuff like this I wish I could see the reaction on some modern Apple employee's face to 1) the fact that all that stuff existed back then and 2) that someone is actually using it for anything practical. There's got to be at least a few people who don't have a clue.
  9. I would think the only point of throwing an actual memory slot on there would be the possibly of using existing memory sticks and replacements if failure should occur. Any time a component is soldered down it becomes significantly more complicated to replace if it fails.
  10. This is complete conjecture, but maybe it's a timing issue/mismatch of some kind? The LCIII is a third again as fast as an LC/LC II (16 MHz vs 25 MHz). So the VRAM stick would have had to be spec'd in a way that can keep up with the faster cpu/system. Suppose that the machine must clear old VRAM in addition to writing new VRAM. If those two things don't happen quickly enough there might be some ghosting as some information lingers long enough to be seen in multiple 'frames'. Although it's weird that you have afterimages that are oddly placed left/right and/or up/down of the 'actual' image which might lead one to thinking that horizontal/vertical synchronization is also fishy. Maybe it's not rendering the image in exactly the same spot each time? P.S. If the LCIII you borrowed the VRAM from works, maybe test it with it's "original" VRAM on this particular monitor and see what happens?

    Got this cool looking, old terminal.

    I mean somebody got a literal 1930s teletype working on a Linux box with some custom hardware adapters, so surely a dumb terminal would be just fine. Of course you probably do need to configure the Linux end properly. https://www.curiousmarc.com/computing/teletype-model-19 https://adcurtin.wordpress.com/2014/01/26/adm3a-ancient-dumb-terminal/

    sTunnel and Gmail on Mac Plus

    What version of the OS are you running? Could you just use a more recent version of Eudora like Eudora 3.x? Might be some meaningful tidbits on this webpages: https://www.fenestrated.net/mac/68kMail/ https://lowendmac.com/misc/01/0716.html https://www.jagshouse.com/mulberry.html Looks like Mulberry Mail is one of the very few options you have for 68k mail clients with SMTP auth support: https://www.macintoshrepository.org/2681-mulberry-2-x-email-client- ^ looks to be downloadable here, though IDK what the feature set is without a license key.. http://bylenga.ddns.net/index.php?page=68KEmail.php ^ a little setup explanation

    Macintosh Performa PSU wrong voltage

    Could be referring to an optical isolation device. They are a circuit component that allows transferring signals from one point to another without a conducting electrical path by the use of an optical sensor pair. https://en.wikipedia.org/wiki/Opto-isolator Assuming I am reading the markings correctly those two 4-pin ICs next to the transforming are probably these: https://www.farnell.com/datasheets/73758.pdf P.S. Just my barely informed two cents, but it's probably worth checking the supply voltages on all the ICs just to be sure they're getting the power eneded to be functioning correctly. The same goes for verifying the output of regulator ICs to make sure it's what it should be, at least voltage-wise.

    Is the Wiki dead?

    Is there any kind of consensus on what's going on or what the plan is going forward? The 'wiki' seems to be stagnant and honestly the 'articles' feature provided by the forum software seems visually subpar. What's the point of having either if neither is useful or getting contributed to? I'm willing to be there is a lot of at least nominally useful information that's either buried in forum threads or only out there in print form or on some random, and really anicent, website that may nor may not continue to exist.

    AppleTalk net cable

    Not sure on the date, but I ran across the following yesterday. http://www.tmetz.net/os/Apple/Inside_AppleTalk.pdf That might be useful. Appendix A: LocalTalk Hardware Specifications begins on page 520 of the PDF. So, I take it that for a proper network you need the little adapter boxes one way or the other? The advantage of PhoneNET being that you don't need the special 3pin miniDIN cables?
