    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...

    Rebuilding an Apple Network Server ANS 500

    Time for part 2! I didn’t prepare the photos for this part, as I was eager to progress on the ANS before posting this second part so I would be able to tell you about an epic rebuild and finish with a: « It’s alive! ». Unfortunately, well it’s not. At least not anymore at the moment. Let me...

    Tales of a bombed Quadra 700: the "short" lived victory

    I wasn't, but the resistance is pretty low, around few ohms, I took some time to check against a working Quadra 700. Good to know, Quadra 700 have a very low resistance between the 5V rail and the ground, no need to freak out like I did. I started to continue cleaning up the bombed Quadra 700...

    Macintosh Classic won't start

    You should remove the flyback and the speaker. Never had problems with transformers. I always rinse the board before removing the caps to get rid of most of the gunk and the infamous fish smell, let it dry, then remove all caps, then do a deap clean, then resolder everything, the only classic...

    ANS 500 Rom

    No, a system dump is a partial or complete copy of the RAM not the whole address space (that would be huge). The ROM maybe cached in the RAM but I have absolutly no knowledge about this.

    ANS 500 Rom

    Thanks! System dumps are a different thing, as far as I know it’s not able to do a ROM dump. I’ll try to find a command compatible with AIX, so we can dump the ROM. Just ordered mine yesterday, but it will took sonme time before I could get the ANS back to life. I’m wondering if there is...
