Hallo! 8.1 installer is in fact a 8.0 install with 8.1 update installed right after and updated utility disks for HFS+ support. You will find everything you need to properly upgrade to 8.1...

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...

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!

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...

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...

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.

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...

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...

Hello there, This a story of one of those computer you never though you will ever see for real. Then you got one. I'd like to start with a warm thank you to @zefrenchtoon who put me in touch with the seller of that big lot of macs in France, and of course, many thanks to the seller who was...

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...

Hello, Let me tell you the terrible tale of the bombed Quadra 700. Do you feel that sensation traveling your spline? Fear! You name it! That’s the feeling I had when I took off the shelf this freshly bought Q700 and I heard something moving… Removing the top revealed what everyone fear the...

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...

As usual, an amazing and incredible work! Thanks for giving us the opportunity to fix our IIfx. Now there is some hope for my bombed one. 🙏

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.

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...

Whoa! Thanks!

Yes the ROM dump is probably the trickiest part. I might be able to build a ROM module if I can find a already designed PCB and the proper EEPROM. Here is what I already find so far: http://sphinxgroup.org/Apple_pinouts/Firmware_Module_Pinout.txt...

Found none so far… but it’s likely that my only solution is to find a dump and make a repro (which is out of my capabilities) . Unless someone has one from a dead ANS.

Thanks for asking! Yes, in the service manual there is no part number for the ROM. :( It seems to be the same as the 9500/9600 format but with 8 chips, unfortunatly the only picture I found was to bad to see anything. (The ROM simm format seems to be the same across every Mac with this kind of...

Hello, I recently acquired an ANS 500 in a pretty rough shape, but with some rust fix and cleaning it should be fine. Unfortunatly, there was no cd drive, hard drive, and RAM/ROM sticks. As far as have seen, the ROM stick seems to be mandatory. Can a kind soul with an AWS 500 confirm this...
