  2. Macintosh Color Classic Sound Issue

    Thanks you for your suggestion! I'll look and see if I have any capacitors lying around that will do the job after I get home from school. If not, I'll order some today or tomorrow.
  3. Scutboy's Stuff

    I'd have been ecstatic just to find a Sun thing, getting some Macs is just icing on the cake...
  4. Macintosh Color Classic Sound Issue

    Capacitor issues around the audio DAC chips in anything from the II, LC, or (Color) Classic series' usually results in dead, or very faint, sound. That would be my first suspect too. To test it out, you can first desolder and replace the caps around the TI amp/dac chip, which should be labeled 343S0129, and then try powering it on to see if you get sound. Warning: If you go with tantalum chip capacitors like most of the people around here do, note that the polarity stripe on tantalums denotes positive, and not negative. Certain tants can be quite explosive if connected backwards. Make sure the stripe side is positive. If you do replacement aluminum can caps, this is a non-issue.

    I bought my adapter for about $ 25 several months ago and was proud of this good purchase, as I never saw this adapter before and after. Until yesterday I thought I was to stupid to install this adapter.
  8. Macintosh Color Classic Sound Issue

    Hello! I recently purchased a broken Color Classic off of eBay and it arrived in the mail a few days ago. The capacitors on the logic board are leaky and I ran the board through the dishwasher to get all of the goo off. After doing this, I managed to get the computer to work and I plan to recap the logic board in the next few weeks. However, the sound suddenly stopped working when I booted it up today and at first I thought that the volume was just turned down. After turning it up, there was still no boot chime or any audio of any sort. Then I realized that the Color Classic was producing sound, but it was so quiet that even the case fan in the computer overpowered it. Trying to narrow down the cause of the problem, I plugged headphones into the machine and powered it up, hoping for the best. I got a perfect boot chime at normal volume! This leads me to believe that the logic board is not the culprit, although I still plan to recap it since the capacitors were leaky. I have a suspicion that the analog board is causing the problem and that it needs a recap. Can someone confirm this before I order a bunch of capacitors and start the painstaking process of replacing all of the caps on the analog board? It would be great if someone could point out the capacitors on the analog board that deal with the audio so that I would only have to replace those. Also, if I am on the wrong track and the problem is something totally different, please let me know! Thanks! Alex
  9. Feeding VGA 31KHz to a Classic II CRT?

    Indubitably, but out of curiosity, what besides the Flyback would need to be swapped out on the stock A/B to achieve workable frequency ranges for higher resolutions/grayscale?
  10. Farallon EtherMac MicroSCSI

    I only used my Asante MicroEN/SC maybe twice with my PB 180 probably ~20 years ago. It worked fine then! Back then I had several external SCSI enclosures and Appletalk-capable Macs and the internet was still mostly dial-up so there wasn't much need for it.
  11. Using FloppyEMU without a case?

    Been a while since I've had time to hang around here! I am playing a bit with my vintage computers again. I have a floppy emu and am rediscovering how much I love it. So much, that I'm seriously starting to think about buying additional units so that I can keep them permanently attached to different machines. Does anyone out there have much experience running a Floppy EMU long-term without a plastic case? For my first one, I bought the case, and it works great, but I wanted to chop all my fingers off after putting it together. I am not handy with the small parts (vintage computer hobbyist irony alert). Not complaining, I think it's wonderful that BMOW makes the case available at all, but I would like to avoid the pain of putting that thing together three or four more times. Does the board get dirty or damaged too easily if you use it naked? Any tips for storing/protecting it without the case?
  12. Feeding VGA 31KHz to a Classic II CRT?

    It's probably the easiest solution... You just need the circuitry. It'll probably fit quite well where the Analog board sits.
  13. Picked up a QS'02, and other updates.

    Eject Extras 1.0 Created Tue, June 26, 2001 Version: 1.0, Copyright Apple Computer, Inc. 2001 So no Installer from before that date will have it. Looks to me like Apple developed and provided it to address the remarkably inept decision that the QS front bezel design would suffer from implementing a near universal I/O convention. Form over function within the Infinite Loopiness . . . naw!
  14. Mac SE/SE/30 Ethernet Card Recreation

    I haven't looked at the SE PDS pinout, it's a subset of the 030 slot as is the LC/LCII PDS. It also uses the same connector as NuBus and LC. That connector fits within the 10x10cm square for someone to run a batch of inexpensive test PCBs. Such a board would also have space for a couple of other test setups. edit: that would be someone else doing the PCB/testing, not set up for it ATM. But with help, I could map out the connections for a test PCB in Illustrator for someone else's playtime.
  15. Picked up a QS'02, and other updates.

    The app would probably be good for exactly what you described. In Mac OS 9, the function keys can be made to launch programs, and you can also leave aliases to it wherever might be relevant - Apple menu, root level of your disk, desktop next to where the CD icon would show up, whatever you prefer.
  16. Mac SE/SE/30 Ethernet Card Recreation

    This pic of awesome LC PDS multiple slot adapter came up in the eBay finds thread. Looks like it would have to go in one of the expansion boxes to get the lid on it. At any rate it got me thinking about memory mapping. 1 - Each Slot ID has its own layer in the I/O memory mapping chart, so that shouldn't be problematic. 2 - Control line remap appears to be simple enough: 2 - In that case, only the Slot ID remains to be spoofed on an adapter. 3 - The LC NIC assumes it's addressed at /SlotIRQ.E but has no way of knowing which line is pulling its chain. 4 - Remapping /SlotIRQ.E to any of the three available 030 IRQ lines (bold black) requires only the two jumper setup of 030 cards. 5 - As I understand it, the system detects a card on any available interrupt at startup and Slot Manager takes care of the rest. 6 - Slot Manager shouldn't care which line it needs to yank, just that it's servicing whatever was detected at startup. 7 - NIC drivers are commonly set up to handle PDS and NuBus setups alike, so maybe?. Dunno, looks simple enough in my caffeine deprived musings this morning. Anybody got a comment on any of these points?
  17. Farallon EtherMac MicroSCSI

    I had the exact same issue with my Farallon SCSI adapter. It was the larger desktop version, but I never got it to work. The lights would flash on boot and when loading the driver, but then nothing else. Also, if I ran the network utility, it'd freeze the computer. I eventually sold it as salvage. I never did figure it out. I sure hope you do, you seem more knowledgable about the technical side of it.
  18. AEK typing gibberish in text entry

    Could you run a patch wire and permanently ground Pin 24? Or would that mess it up somehow?
  19. Scutboy's Stuff

    Nice looking system! Never hurts to ask, although I never do. I rarely do business on Craigslist tho. That’s one clean looking system!
  20. Scutboy's Stuff

    That's what I was thinking. It certainly probably cost almost as much back-in-the-day.
  21. Scutboy's Stuff

    The RAM might be worth more than the computer.
  22. Yes, you guys are thinking of the Desktop Manager, which was part of AppleShare Server for System 6. It was quasi-experimental at the time, and introduced the split Desktop DB/DF files that were later a part of System 7.0 in 1991. Some threads about it: https://macgui.com/usenet/?group=14&id=48013 https://macgui.com/usenet/?group=14&id=47729 https://macgui.com/usenet/?group=14&id=14819

    Incredible! Nice find!
  24. Scutboy's Stuff

    Craigslist can be your friend - and always be asking questions... I answered a CL ad to pick up a period Sun monitor (GDM-1962) for some of my lunchboxes. Nice older gentleman; asked if he had any other items and he mentioned he also had "some old Apple stuff" in his garage that he'd picked up over time at 3M surplus auctions... I came home with the IIfx (128MB RAM, 230MB HD, Ethernet card, monitor) a dual drive SE and a 512k with no keyboard, but didn't have enough cash on me for the 2 IIcx or 2 Quadra 700, along with a couple more of the Hi-res RGB monitors. One of the Q700s looked pretty beat up, I may just get one IIcx and the good Q700. IIfx was clean as a whistle inside. Put in two good batteries and it fired right up. I did a quick 7.5.3 install and all seems well. Guy also had a bunch (like 19) NCD and HP Xterminals and an HP9000 to run them all. While there was a time in my life I would have thought that was fun, I had to pass on that many glass monitors! He says he also has some plotters and other "goodies" in storage.
  25. Can you identify this PB Card?

    Ah ha! I knew I'd seen that card somewhere before, but it's been a long time ago.
  26. Newton eMate 300 - whats card is this?

    Dial up modem. It is a pop out phone jack.
