I added a Sonnet PPC card to a Quadra 700 and am now struggling with the MacOS 8.5 installation. The 8.5 system is installed, and I'm trying to follow the post installation instructions which require two files from a startup floppy that came with the card to be dragged onto the hard drive, after...

Thank you. Upon closer inspection with a magnifying glass I was able to find the traces, and with a fibre glass pen scratched the solder mask away and soldered on a replacement. Not pretty but does the job. Re the drive - it was the adapter that's bad, apparently. Swapped it out for the Texelec...

Two part question: 1. I am trying to revive a 720k floppy drive from a PS/2 model 30. The PCB on the underside of the drive had one of the surface mount capacitors fall off (C9, 22µF / 16V), so that's one obvious candidate to fix. However when I cleaned the area, it revealed that the pads were...

I got the files (including for replacement clips for the side panel) here: https://cults3d.com/en/users/ktkm/3d-models They fit very well!

I added an internal CD ROM drive to my Quadra 950 but only had the solid bezel, so I 3D printed one with the right slot for the caddy. It's very white so I'd like to paint it with the right colour. Does anyone know what an easily recogniseable colour code or name would be that I could find...

Things I tried: removed all RAM and VRAM, cleaned contacts, cleaned sockets and plugs/connectors tried using a SCSI2SD V5.5 with a known working installation into the external SCSI port with all internal drives disconnected re-setting the internal SCSI2SD using a new SD card using a new SD to...

Thanks for the tips! I should have mentioned that I have a working SCSI ID configuration (4 SCSI2SD devices configured as 0, 1, 3, 4, and the CD-ROM at 2) which was working perfectly fine when I had everything dangling out the side. It was only after assembling all the components in the very...

Hello everyone, For a few weeks I've been working on my Quadra 950 which came to me in working condition but no hard drive in it. I did a thorough cleaning of the case and all interior components, cleaned and lubricated the floppy drive, and it was booting nicely and I was able to install...

[I hope it's alright to post this in here, seemed to be the most appropriate forum type] I just added an internal Sony CDU-561-25 SCSI drive to a Quadra 950. I have it jumpered to be on ID 2 as per the attached configuration (or so I thought, keep on reading). It's in the middle of a...

Thank you for the pointer - I went through all the SuperMac labelled on on https://wiki.preterhuman.net/List_of_NuBus_expansion_cards and none of them matched visually, especially with the mini DIN connector. On further research, that seems to be the right direction though (see this 68klma...

Hey all, I have this card from a IIx, and none of my searches have come up with anything so far. I only guessed this was a video card by the term "vram" mentioned on it. In some searches I found the name "Thunder" but none of the images I found seem to match this one. It does have a 15 pin port...

Upon closer inspection with better light and some magnification (and cleaning), the smaller ceramic disk ones seem to say "001M" or ".001M" not "COIM", wouldn't that point to .001 pF not .001 μF ? The 25R could also be Z5R which seems more in line with temperature and tolerance specs - 5-85°C...

Thank you so much for the details, much appreciated! I've attached a picture with the component I mentioned. General update: it took me a while to remove both front edge connectors from the motherboard. There was so much corrosion I could not pry them off with heat so I had to cut away at them...

Hi there fellow Lisa (and other) aficionados! I have started the journey of repairing a heavily battery bombed Lisa 2 (Frankenstein/modified model, it has an internal hard drive + a parallel port). Right now I am tackling the motherboard which has most of the damage, hoping I can get it back to...

Regarding temp and duration - I've had some mild crud on a PCB from SMD caps leaking. I did 9 minutes at 65 Celsius (one side only) and not much came off, and I had to give it a good scrub afterwards to get everything off. How long do you typically leave your PCBs in the cleaner? 5-10 minutes is...

Would anyone have access to documentation on the jumper meaning and configuration for a 5.25" HD (1.2MB) floppy drive, model number YD-380 (manufactured for IBM by YeData). The only documentation I found were copies of maintenance materials which do not contain any information about what the...

I finally managed to get the computer back together after restoring all the bits and pieces, and even got it to boot from the built in drive, which dropped me into a Xenix System V boot prompt (how interesting!), but doesn't progress any further from there (sector issues reported). I'll see if I...

I have an IBM 5170 board which suffered some damage from a leaking battery. It's mostly cleaned up but will most likely need some components replaced soon. Specifically, does anyone know what the component pointed to is? It's labelled FB2 and sits behind the backup battery connector by the...

I followed your recommendation and got one too - love it! Works every time, when my other, cheap generic brand new one fails to read or write every second disk (and I know they're still good). Thanks for the tip!

For those who are using ultrasonic cleaners for boards (and other computer related components, if applicable): What sort of cleaning solutions are you using, if any? There seem to be quite a few that seem suitable for use on electronics. Bonus points if they're available in the US :-) Also, any...
