Just sharing my most recent achievement https://ironborn65.synology.me/photo/mo/sharing/FMWU48xY7 lead battery replaced BlueSCSI implanted DIY Custom SCSI 8MB RAM card there is thread here where I described how I replaced a faulty SWIM...

is not the "molar" a compact?

long story short: replacing a fan with a low noise one will reduce the cooling ability, assuming the original fan is not worn out or producing excessive noise. Is it?

I have heard comments that the noctua fans are indeed silent but the RPM is low, and as such they can not extract as much heat as the more noisy one, resulting essentially useless. Any comments with experience to share?

Tattletech is the one you need, just try a different img, dsk or sit file Try this attachment, rename it to .img first (the site does not accept a .img extension) Tattletech 2.17 created with diskcopy 6.3.2

have you tried to run TattleTech and see if the card is visible? At least to see if the card appears in the PDS bus

interested!

I successfully completed the ATX conversion. I connected the fan and the relay for the 230VAC for the monitor. To reverse the PS-ON I used a NPN. To avoid a larger PCB I inserted the resistors in the wires protected by the heat shrink insulators. The NPN transistor is connected to the 3 wires...

correct @pizzigri , the model is 820-0360-B, I just added it to the README. Replacing the PS is IMO already doable from the kicad file or from the dxf, but it's outside of my comfort zone due to lack of competences, I just did some donkey work

I have enabled AFP back in the Synology(*) Initially all the files in the shared folder were sit archives, or hqx or disk images. By chance I expanded a sit file in the shared folder from a connected Mac and to my surprise data and resource forks were preserved. I can leave the uncompressed...

I wish I have such friends :) mine are making fun of me for my collection and retro mac passion

Mm, you can consider to lay some metallic/aluminum tape inside along the entire diagonal, covering the crack and more to give it more strength. Glueing a thin sheet of metal or plastic can also help, still I can not recall how much space you have. The pros is that it's invisible and it preserves...

Congratulations, it's great machine. The "made in France" sticker (of course it was not) and the french flag in the desktop make it all a bit weird, I could guess the previous owner was a french guy/lady leaving in Japan

got it! :), tks you all VRAM: no 512k supported? VRAM speed: 70ns or 80ns?

I will add a spare SE/30 32bit clean ROM I have

I got it home, amazing machine! No electrolytic caps, PSU is fine ... "boong", happy chime :) EU 165 with NIC card + Apple video card + keyboard, the case is yellowish but without damage, it comes from a law firm office oh + FDD + 5.25 HD, these are still to be tested but first a thorough...

yes, but instead of cycling x times option-command-pr, just switch off the battery and restart.

Since it seems a recurring issue with some Mac, why not hacking the battery holder and adding a switch, accessibile from outside, that disconnects the battery?

Thank, for the IIsi can be tricky because an ATX does not fit in, not even a SFX.

got it guys, tks @joshc , I'll go for the Seasonic SS250-SU I'll later undo the PSU of the Mac IIsi, currently with the +12V PSU + picoATX I'll try to save the filtering circuit and the relay for the monitor plug driven by the +12V, I think it does not hurt if the Seasonic has it'd owns, is it?
