    Help with SCSI names (Color Classic)

    The one on the back of the CC is a DB25 - the bottom Centronics 50-pin is really big, 1.5 times the width and perhaps more in height compared to the DB25 https://en.wikipedia.org/wiki/SCSI_connector has a really good photo comparing the three kinds you're referring to (the ones on your CD drive aren't Centronics 50), including what looks like your exact CD drive! I've not used the one on your CD, but I think it's an MD50
  2. Does it eventually go through to the desktop with enough waiting? (could be 5 minutes or so). If it does (hey, even if it doesn't), try booting from a CD and deleting the System Folder/Preferences/Appleshare Prep file if it exists. It may be a long shot, but it fixed a problem with symptoms exactly like you're describing: booting to the desktop, freezing, but mouse pointer can move about. I've had it suddenly become problematic even when I haven't been using filesharing or even networking for several boots previously.

    Powerbook 500 with 167MHz PPC603ev

    A few pics of my latest - a powerbook 500 with Newer Technology PPC603ev at 167MHz, 24MB RAM, Active matrix colour display and 500MB HD (probably soon to be replaced with SSD).

    Apple IIc label

    The 'Power Supply' typeface looks like another of Apple's uses of Univers, also used on loads of Keyboards until relatively recently. My guess is the bleedy quality could just be due to the difference between a fresh inking of the stamps that imprint the label, and a later point in a run where some of the ink is used up. They're different stamps with slight differences in the design, but the squishy edges may just be that variance through the production run.

    CPU Processor - How hot is too hot?

    IBM's own datasheet on their PPC740 and 750 (the G3) CPUs mentions temperature a few times. (find it at http://datasheets.chipdb.org/IBM/PowerPC/7xx/PowerPC-740-750.pdf ) Some relevant parts: Storage temps are OK from -55 to +150C Recommended Operating die junction temp is from -40C to +105C Page 38 about the thermal assist unit notes values provided for reading temperature, and that temperature readings of the chip are of the junction temperature. Page 49 has some calculations for heatsink/airflow, with the sentence "resulting in a junction temperature of approximately 71°C which is well within the maximum operating temperature of the component." The datasheet references 300-533MHz G3s - I don't know precisely how close they are to the G3MT CPUs from a bit earlier, but I'd say it's fair to say at 47C you have a fair bit of room.

    Vintage Rubber Feet + Bare Wood = Very Bad?

    I had similar - a color display sitting on MDF for years, and it was fine. No marks left on it. I pulled it out while setting up a 6360, and sat it on a satin-coated set of drawers. Overnight it turned to a sticky awful liquid. I can only presume that age had made it sensitive to whatever is in the coating of the wood on the top of the drawers, and the rubber was stable until it came into contact with that. Then it turned to goo.
  7. Now it's iMac from 2016, speakers from 1993, keyboard from 1991, desk from 1982 and walls & window from 1860something. It's almost like it all belongs.

    Got this cool looking, old terminal.

    It would become a piece of hardware that does the same job as OSX's terminal.app This pic is my vt100 hooked up to my 2016 iMac, a dumb terminal too. It's showing irssi (running on the iMac, displaying on the vt100), connected by a Keyspan Twinserial adaptor.
  9. Wasn't there a delay if you had once mounted a server (or tried to mount one incorrectly) and it was no longer on the network you're on, and you could delete a file in the system folder that'd fix that? It's one of those files I always *always* forget the name of, and have to go on a google hunt to re-discover. Clearly I have a hole in my memory that the facts fall into. Happens for me every few years on my (few) OS9 machines. It takes a boot from ~40-50s to several minutes, sometimes.

    475/605 motherboard in 550

    I suspect somewhere along the way someone has mixed up that the 575 and 475/605 boards (which are meant to be pretty much the same logically) are compatible physically, and they're not. It'd be worth dropping a message to lowendmac and letting them know that's wrong.
  11. If it's not the pots, there's another spot on the analog board that can give those symptoms - mine had the same flickering purple issue. A couple of dry solder joints underneath the highlighted part marked below - and especially bad on the green, which was dropping out (leaving R+B = Purple)

    Performa 6360 dual PCI slot mod

    There's nothing on the back, just the resistor and a couple of caps on the connector side that I can see. h

    Performa 6360 dual PCI slot mod

    For context for anyone else coming by this thread, the one-slot riser in place in the 6360 The dual-slot and single-slot risers together: The two slot in place in a couple of views: If you were prepared to do some case surgery and lose the TV connector slot and the internal video position then the riser would fit. There's a lot of case innards in the road, but nothing *important* nowadays. The big issue is that the top of the dual-slot riser card would sit very close to the rear of the CDROM's connector. It looks like it *may* clear it - but even if it does you couldn't fit a PCI card in the top slot any longer than the riser itself. Edit: looking more closely, even the lower slot pci card may intrude on the CD cables and the metal clip holding them if it were longer than the riser.

    Performa 6360 dual PCI slot mod

    The electrical compatibility is certainly good, my 6360 board worked here in my 6400 (with the dual slot riser) fine when I stole the 6400's faster board (actually from a 6500) to pep up the 6360 . Whether the power supply in the 6360 can handle the two cards you'd like to use may be another matter. The dual slot riser is quite a bit taller in two ways - not only does it have an extra slot, but even the first slot is a good deal taller than in the single slot riser. I shall get you photos in a moment of the 6400's dual in my 6360.
  15. No other place for it than in one of the quintuplets!
