    China Ebay 68040 processor

    Every 040 has a FPU. Probably why the software reports hardware FPU present. Technically this is true, the chip has an FPU. LC's are just 040's that have faulty FPU's that were disabled by blowing fuses on the chip. This happens during testing. If the chip passes all other tests but has a faulty FPU it will be downgraded.

    ID Mac Plus 030 upgrade card

    From the more-stuff-I've-had-so-long-I-forgot-I-had-it category... So while digging in the garage I found several spare compact mac boards. Among them was a Plus board with this unknown (to me) '030 upgrade card. It looks like it requires extra power. It appears to be a 25Mhz '030. (I didn't want to remove the sticker and void the warranty!) It piggy-backs on the original processor and has no manufacturer name anywhere on it. I did find this:http://appletothecore.me/files/mac_plus_with_68030_upgrade.php Which appears to be the same card. And appears I'm missing some associated hardware. Can anyone here ID this card? Thx,
  3. Yes, mines an 030 but as I mention above, I am assuming the cards might share some similarities in configuration. Perhaps someone, somewhere has a manual for the Mac20 they would share.
  4. Here's the manual for the Novy Quik30. (Your card is a Novy Mac20 MX I believe.) Might be of some help assuming the cards are similar enough. Novy_Quik30-compressed.pdf
  5. The eprom missing the sticker over the window could be an issue. Also, don't know about this particular card but the Novy card in my Plus requires all the ram slots filled, either on the card or in the Mac. When the ram on the card is used any ram in the Mac can only be used as a ram disk.

    Flea Market Mac IIsi and Mac II(fx)!

    Rather amazing they both still work. Someone spent thousands and thousands on the FX. The ram alone probably cost more than a grand back then!

    68882 FPU p/n & mask

    Masks refers to the photo mask set used to "print" the parts on the silicon wafers. Mask changes are done for a variety of reasons. To fix bugs, or process changes, or shrinks. The most common reason for different rev numbers are for shrinks or different packages. (Plastic vs. ceramic.) I would expect for use in a Mac that all the 68882's would be functionally identical, the only difference would be packaging. (Plastic vs ceramic.) Exact differences will documented in the Motorola spec sheets. Imo, any 68882 that will physically fit in your socket should work. I worked at Motorola for many years. C74N ('030) and C12R are two numbers I remember very well as I ran thousands of wafers of these back in the "old days".

    lisa sin remarketing drive

    You probably already found all this but in case you haven't. https://computerarchive.org/files/comp/manuals/apple/lisa/
  9. A little late to this thread but a few years back I installed a Pioneer DVR-115 in my G5. I had to remove the front cover from the drive tray. It works perfectly in the G5, opens & closes the G5 door without issue. I have used other model drives (Sony) in other G5's and the tray couldn't push open the G5 drive door without assistance.

    Booting Mac Plus with scsi2sd...

    Have you seen this thread?
  11. I don't remember which TiBook it came with. I got it when I was doing IT at Motorola. (2000-05) The newest files on the disk are dated April 19 2002. (I guess that would make it for a 667 MHz or 800 MHz machine, based on their release date.) The read me says Mac OS 9.2 but the disk installs 9.2.2 (And says 9.2.2 on the disk) I have an earlier PowerMac G4 CD that is Ver. 1.0 that says 9.2 on the disk. The files are dated June 21 2001. I labeled that disk "most systems" back in the day, as it installed the OS on "most" systems.
  12. I have an original 9.2.2 install disk for the TiBook (PowerBook G4 CD Ver. 1.2 Circa 2002) that worked with any system that supported 9.2.2 back in the day. I used it on most every model including iBooks, B&W G3's, ST & QS G4's etc. Iirc, it was about the last stand-alone OS 9.2.2 install CD that I remember before "Classic" was introduced.

    ID Mac Plus 030 upgrade card

    I've always used a small flat head screwdriver. However it requires extreme care to not break the very fragile tines.

    Broken floppy drive?

    Did you disassemble the drive and clean out all old gunky grease and re-lube? The disk carrier assembly can be removed and cleaned.
  15. ^^^ What nglevin said. Just install an ATX PS. I replaced the PS in my MDD G4 twice and was ready to scrap it when the stock PS failed for the third time. However, I decided to try the ATX path and it worked like a charm! Follow the instructions here: http://atxg4.com/mdd.html I didn't use a mod cable I just rearranged the pins using the proper molex extraction tool. (Without which it's basically impossible to remove the pins.) I did have to use an 24 pin extension cable to be able to mount the PS inside the top of the case. Also, I haven't had any issues with "deep sleep" although I usually power it off when I'm not using it.
  16. Yes, Motorola had their own daughter cards. They used a socket that could accept a BGA part. I have some photos of the card we used with the P58 motherboards on my other computer, I'm out of town right now. Here's a photo of two systems I set up to do accelerated life testing with the 7448. I cranked up the voltage and the temperature and and ran the parts non stop for about three months to induce voltage threshold shifts.

    Insane SCSI to FW prices

    Good grief, you're right! I had no idea. I found an Entegra, I think, adapter in a box of my cables a while back and thought "I'll never need this." (Of course I'd need drivers that are probably OS9/XP only.) I guess I should hang on to it.
  19. There's about a 100% chance the tiny nylon gear in the eject mechanism has stripped/disintegrated. The good news is you can get a replacement.

    What's on that old hard drive?

    I fired up my FrankenBook 165/180 a couple of months ago for the first time since ~2000-2001. I was surprised it still worked. I was even more pleasantly surprised to find a bunch of photos that I thought were gone forever! The photos originally were on a drive that failed my PM8500 in ~1999. I didn't know I had put copies on the PowerBook. As far as disposing of HD's, at the High Tech Company where I used to work if the computer was going to be redeployed the drives were just wiped. If the computer was being "surplussed" i.e. scrapped, the drives were removed and destroyed. Sadly, when it came to Mac laptops many of them were just ripped open and the drives removed. (The IT guys were pretty lazy...) Most of the PC laptops were leased so they avoided this treatment.

    2 Odd Nubus Video Cards

    Ahh, yer right, I didn't look at the photos close enough. Need moar coffee.

    2 Odd Nubus Video Cards

    The second card with all the VRAM may be a Radius Direct Color 16/24 I found a reference and photo here: http://www.retrotechnology.com/herbs_stuff/m_nubus.html
  24. Yes, my stating "OSX 10.x" was probably overly-broad, considering how many versions of "10.x" there are.
  25. Why FAT16? Why not FAT32? And no, I do not believe OSX 10.x will read or write HFS.
