    Macintosh LC III recap - Capacitor Recommendations?

    I recapped my LC III a while back with tantalum caps I got from @trag. I more recently recapped a Color Classic and LC 520 board with tantalum caps I ordered from Mouser: 10µf - 16V - SMT - Size B - Mouser #: 581-TAJB106K016 47µf - 16V - SMT - Size C - Mouser #: 581-TAJC476K016SNJ 100µf - 6.3V - SMT - Size C - Mouser #: 581-TAJC107K006R Same types are used on the LC III. Admittedly I haven’t really thought much about electrolytic vs. tantalum caps so I’ll leave that to others to discuss.
  2. I’m somewhat interested in playing with A/UX. I wonder if there is a version of Perl that would run on it for network related utility CLI scripts doing ftp, etc. Maybe just shell scripts would work there. Would it make a useful server for other old Macs running System 7.5 or below? In anyway better than an old Mac running Mac OS 9 from a Unix level integration prospective? Likely limited by telnet and ftp for integration with modern systems...

    I picked up a Power Macintosh 9600/200MP off Craigslist last month and have been meaning ask: Anyone know if having an external SCSI terminator directly on a Power Macintosh 9600’s external DB-25 SCSI port is a normal thing? All the Internal SCSI devices are on the Fast SCSI bus, but thats similar to my 7300 and it doesn’t have a terminator like this and works fine. Maybe something particular to the 9600? ...or the previous owner could have done this for no legit reason I suppose.

    Update on my Performa 6360 with a 6500 motherboard. I had been running it with a pair of 64MB FPM 5v DIMMs from my 7300. I got a pair of 64MB EDO 5v DIMMs off eBay and according to Newer Tech Gauge Pro there’s a ~10% memory performance improvement. FPM: EDO: It’s kinda academic, in my general playing around I don’t really notice much difference but thought I’d share nonetheless.

    IIsi CAP kit ordered...

    I successfully recapped a IIsi power supply recently, the following resources were really helpful: Recapping A Macintosh IIsi Power Supply (PSU) - Paul's Old Crap (YouTube Channel - Paul's Crap): https://www.youtube.com/watch?v=Tknr_9UdsIc Thanks @netfreak ! Recapping a Macintosh IIsi Power Supply (YouTube Channel - Branchus Creations): https://www.youtube.com/watch?v=YNsPr1mHUrw & Recap-a-mac - Macintosh IIsi Power Supply: http://recapamac.com.au/macintosh-iisi-power-supply/ (Awesome Hi-Res annotated board pictures!) I think he's a member here but not sure who , Thanks! I spent a lot of time measuring the old capacitors and searching through Mouser's site to try to find the best fit with my admittedly pretty rudimentary understanding of what's important to match up beyond the capacitance, voltage and type. Here's the parts list I put together/ordered/successfully used: IIsi Power Supply (Sony) Qty x Cap µf x Cap V - Cap Type (Cap Board ID(s)) - Measured Cap Diameter x Measured Cap Length :: Mouser Part # - Part D x Part L - Cap Life Rating 2 x 220µf x 250v - Radial (C101, C102) - 19D x 35L :: Mouser 647-UCS2E221MHD - 18D x 31.5L - 10000 Hour 2 x 2200µf x 6.3v - Radial (C202, C203) - 10D x 30L :: Mouser 647-UPJ0J222MPD - 10D x 31.5L - 5000 Hour 1 x 100µf x 10v - Radial (C106) - 4D x 10L :: Mouser 647-ULD1A101MDD1TD - 5D x 11L - 10000 Hour 2 x 220µf x 16v - Radial (C221, C222) - 9D x 12L :: Mouser 647-UPJ1C221MPD - 8D x 11.5L - 5000 Hour 2 x 1200µf x 16v - Radial (C211, C212) - 10D x 30L :: Mouser 647-UPW1C122MPD - 10D x 25L - 5000 Hour 1 x 47µf x 25v - Radial (C402) - 4D x 12L :: Mouser 647-UHE1E470MDD - 5D x 11L -5000 Hour 1 x 100µf x 25v - Radial (C401) - 6D x 12L :: Mouser 647-UHE1E101MED1TD - 6.3D x 11L - 5000 Hour 1 x 56µf x 35v - Radial (C302) - 6D x 12L :: Mouser 647-UHE1V560MED1TD - 6.3D x 11L - 5000 Hour 1 x 4.7µf x 400v - Radial (C105) - 10D x 20L :: Mouser 647-UPW2G4R7MPD - 10D x 20L - 5000 Hour IIsi Power Supply (Sony) - Daughter Card: Qty x Cap µf x Cap V - Cap Type :: Mouser part # - Case Size Code 1 x 3.3µF x 35V - SMT :: Mouser 581-TAJB335K035SNJ - Size B 1 x 100µf x 6.3V - SMT :: Mouser 581-TAJC107K006R - Size C

    So I got to testing my ”new” Orange Micro FireWire/USB PCI card compared to an ADS FireWire/USB 2.0 PCI card in my Performa 6360 chassis (Mac OS 8.6 hard drive) with two motherboards: 1) Original Performa 6360/160 - Both cards worked fine (as @jeremywork predicted) 2) Power Macintosh 6500/225 - Both cards showed up as PCI Bridge devices but neither USB or FireWire worked. However, the Orange Micro card DID work after running the Orange Micro “PCI Bridge Patch v1.0 for the Power Macintosh 6500, 5500 and Twentieth Anniversary Macintosh” available here: https://www.macintoshrepository.org/6859-orange-micro-orangelink-pci-firewire-usb-combo-card-software Before Patch: After Patch: (A bit odd that the Comm Slot II Apple Ethernet card didn’t show up in System Profiler after the patch but it’s just cosmetic, AppleTalk and TCP/IP continued to work fine over Ethernet.) So nothing really new here I suppose, just confirming what most of the folks here already know.

    Lucky IIx acquisition

    Curious, what’s the edge connector on the upgrade board next to the front of case for? It loooks like it’s still accessible with the cache board installed?

    Rosen Flea Market IIfx Restoration

    No biggie, I'm picking up multiple extras of some stuff in bundled eBay auctions, I should probably see what else I have and post it... It's actually a Farallon 590a-TP, I just tested it in a Iici with System 7.5.3 (that actually already has the same card), seems to work fine. Not sure if how far back it is supported System wise. One of the chips says 1992, so maybe not System 6? Anybody know? @LaPorta IM me if you think it will work for what you have in mind for this IIfx.

    Looks like you could get the cable (and an adaptor for the their Floppy EMU) from BMOW for $17: (although looks like its currently out of stock...) https://www.bigmessowires.com/shop/product/db-19-adapter-and-extension-cable/ I think I have an extra Asante NuBus Ethernet card you could have for shipping, I'll look when I get home.

    LC 475 installation woes

    You need to update the Appleshare software to a later version to be able to do AFP over IP with 7.6. Its probably elsewhere but I think this is what you need: http://main.system7today.com/updates/76x_68k.html AppleShare 3.8.3

    Well done sir! I gotta remember this one.

    Very cool, where does one obtain the right type of adhesive copper foil for a repair like that?

    Is there a difference in 603 generation that would affect relative heat generated between a 6400/200 and 6500/225? I think I read somewhere the the 6500 series got up to 300Mhz because is used a newer 603ev chip that was a die shrink that would generate less heat. i.e. Would a 6400/200 603e generate more heat than a 6500/225 and not be cool with a smaller heat sink? I googled and found a picture of a 6500/275 motherboard and it has a fan, not sure if it would clear the single PCI slot riser from the 6360.

    Which pads? The ones next to the cache slot look like they have a “ROM” silkscreen label. There are some on the bottom too though.
