    What IDE adapters are you using?

    What do you mean by burn? Because if you byte-copie the CD image to the CF you’ll run into problems as CDs have a different Apple Driver from hard drives. To have a working CF you must format it in HFS with a proper Apple partition map and driver first. Then you can try to copy the CD files to...

    iMac G4 black screen on boot, suspicious cpu jumper config

    This is bad but possibly not unfixable, but quite difficult if you are not experienced. There might be broken pads and few cms parts to replace. I would recommend you to cut this wire nest the closest to the board, taking extra care to not tear it from the motherboard to avoid more damage...

    What IDE adapters are you using?

    That was quite an amount back in the day, you also have to consider memory cards where expensive not been a standard format didn’t help. For reference the iMac G3 was shipped with « only » 32MB in 1998. 48MB is plenty of memory for 8.6, you’ll be fine here. Depending on what you do virtual...

    What IDE adapters are you using?

    It depends on the model, could be 117, 133 or 166. (Edit: nwm you asked for LaPorta’s PB I guess, 8.x works fine on any of these speeds) You want at least 32MB for 8.x even it technicaly requires only 16MB with Virtual Memory enabled.

    What IDE adapters are you using?

    I had really strange behavior with disks (floppies or cds) on a 6100 with 8.5, I wouldn’t trust it without the 8.5.1 or 8.6 update. (Free updates) Same for 8.0, I have seen some Macs just crash without the 8.1 update. So that might highly be OS related. Another strange case is my Powerbook G3...

    What IDE adapters are you using?

    As I mentioned it’s probably not the adapter itself, but the CF card that don’t play well with the IDE controller. I used the some adapter board in my 3200 and it went well, but I used an industrial card. Using SD to IDE is fine but be sure to get a good quality SD card, even if the adapter...

    What IDE adapters are you using?

    Almost all SD to IDE adapters like the one above are actually SD to CF adapters (CompactFlash has an IDE mode) They use the same chip and are limited to 25 MB/s transfert rates due to the protocol supported. IDE/Sata don’t play nice with pre-G3 machines due to adapters having only ATA-66 (or...

    Quadra 900 won't stay powered

    Hello, I recently refurbished a Quadra 900 PSU, it had bad capacitors, mostly due to bad storage, all electrolytes replaced with the proper part. Previous recap with the same BOM when fine on a previous Quadra 950 but this just won't stay up. At first the Quadra 900 wouldn't power on, I though...

    PC Compatibility Card Issues

    The 4400 should be able to power the card just fine, it is designed to handle the most power hungry PC cards and the 100MHz is not one of these, but I found its PSU to be way cheaper than the other Power Macintoshes. Mine is due for a recap soon or later, I’m not surprised yours started failing...

    Did I realign my floppy drive head, or am I being overly optimistic?

    Hello, Head alignment is a bit different (it’s about how the head is oriented), you have dealt with track alignment which is fastidious but easier. I made this mistake few times, some drives can’t be disassembled without messing with the zero track detector, I did clean my 6100 floppy drive...

    Availability of RAM Disk under System 7

    Hi, it’s not related to the CPU as every powerbook supports it and the famous Portable. It’s related to hardware support, more precisely support in ROM. It’s described in TIL9334, I didn’t found a link to it yet sorry.

    Download Info - "Curated" link list

    Hi, I was frustrated not being able to browse download.info.apple.com files the way it use to be. Since there is a lot of essential content there, I was looking for a way to get a least a listing. Thanks to archive.org I've managed to get a list of known files, excluding known bad ones (ie...

    Introducing scuzEMU, a SCSI Emulator Utility

    I was hoping for a tool like this few days ago, incredible work! I wish I could help you on this project, but I don't know a single think about Classic development. Maybe it's the opportunity to try diving into this!

    PM 6500: Specific hard drive causes instability?

    Same experience here, with 6400, 5400 and few others too. Pretty much everything above 120GB may go wrong with pre-G3 hardware. EIDE is also quite a nightmare when you try to use SSD with SATA adapters. I switched to IDE HDD with a 120GB limit jumper (the drive will act as a smaller drive to...

    4400 no video.

    You won’t be able to use a 5V 168-pin RAM in a 3.3V slot and vice-versa, unless you broke something. There is 2 notchs on the RAM connector, changing based on the RAM voltage and RAM type (unbuffered, buffered). There is a nice schema here: http://ps-2.kev009.com/eprmhtml/eprma/h870.htm What...

    LC VRAM "For Mac LC Only" -- any risk using in a Performa 467?

    Hi, LC only VRAM is probably 100ns VRAM, which is also fine in a LCII but an LCIII will require 80ns VRAM. It could work, you only may encounter video problems.

    Rebuilding an Apple Network Server ANS 500

    True, true,… just me hating messing with thoses as I know almost nothing about electronics. And replacing a dead PSU with a modern one bugs me, it’s kinda stupid I can’t tell why. 😅 @dramirez Oooooh thanks for share this video, this seems to be exactly the problem I have. I’m currently openning...
