Bought Asante-MC3NB and Macintosh Display Card 8•24 820-0600-A 8*24 from a local Macintosh collector. 8•24 is not accelerated but it works with my LCD screens. I actually had one earlier but I sold it with a IIcx.

In case of using something like DS1085 frequency synthesizer, what are the requirements for the signal? Sine wave or something more squareish? And does it have to be 100.00MHhz or would something like 98.50MHz work? Or should I just order bunch of aliexpress oscillators in various timings and...

I soldered a wire to connect R4-C23 and the soft start works perfectly now. It seems the trace on the backside was the only one corroded. I don't really understand how just a single trace got damaged... Anyways, I got an idea to check the frequency range of my old Sanyo PLV-Z4 projector and it...

I see there used to be MicroMac Speedy for IIfx but obviously it isn't anymore available. The only photos I managed to find are these: https://img.aucfree.com/h431310795.1.jpg https://img.aucfree.com/h431310795.2.jpg https://img.aucfree.com/h431310795.3.jpg It doesn't look particularly complex...

While I am sourcing a "normal" display adapter I checked the HD on my Beige G3. It actually works and it is 250 MB Quantum ProDrive LPS. Based on the files not much has been done with the computer since late 1990s. It has System 7.1 and it served as a plotter print server of a small architect...

Late night update... my first attempt with R4 - C23 jump was not successful but I tried again with a different setup and it worked!

Thanks! At least R4 - C23 was not ok. I tried to jump it but that alone didn't fix. Actually the R4 - via seems to be fine, the trace is gone somewhere else.

I removed the old C9 and C24 with new tantalum ones. But no soft start. There is no voltage going to the white line of the PSU connector when I press the start button. If I jump start the computer it is possible to use the power button behind to turn off. I assume I have to go through the soft...

Update: Jump starting gives me a happy mac chime. No video though, have to find out whether my display is able to handle the Formac ProNitron resolution.

Just got a home delivery of two items. Apple Multiple Scan 15 AV. This screen is ready for recycling bin - the pedestal has missing bits and the image is really pale. The brightness knob has no effect and the longer the display is on the paler the screen becomes. But the IIfx was the reason...

Alright, I downloaded a 100 MB blank HFS image from https://www.savagetaylor.com/downloads/downloads-macintosh/ and simply copied everything from 0 to 50176 bytes (there are bytes 42 44 and the HFS volume name is around there after those). Now I am able to mount this on linux with hmount and...

The "Mystery Drive" is the redacted name of the drive.

I used FWB Hard Disk Toolkit 4.5.2 on my Beige G3 and I plugged the 40MB drive to its internal SCSI. First I took a block image using Device Copy and saved it. The partition list shows 4 partitions: Title Name Type Start Block Size (KB) Partition Map Apple Apple_partition_map 1 31.5...

No, didn't try that as I didn't want to modify anything yet. I still have the drive in the original state so I could have a go. Any specific tool you would recommend?

I used an external HD with an operating system to try out. It started up and worked fine but it refused to mount the internal HD without the correct password. I tried various SCSI tools like SCSI Probe and Lido but they either triggered the password prompt or gave an error.

Not really, the computer used to belong to some NGO so bunch of administrative documents. Straight to shredder.

I bought a new project even though I think Apple Macintosh Classic is a rather boring piece of hardware. It came with an ADB Mouse II and an Apple Keyboard II, nothing special there. The case is really yellow but on the hand the logic board is pretty clean. It had original battery and very...

Alright, I might need a new analog board then...

Yea, it did pass the mem check and I got the disk icon. So I assume the power supply side of the analog board is ok. I don' see any cracks or such on the tube. Edit: I think something shorted on the analog board. I had the case in place while I was testing but I forgot the white cardboard...

First this screen had typical flickering like they do with bad solders. I re-soldered bunch the typical analog board points. After that it worked ok for a moment. I moved the mac around a bit but then it started to flicker again and the picture went down. At the same time my wife said it started...
