@root42 The CPU is indeed a 6501R1, with a conspicuous "OK" drawn on it in purple. How do they die?

Anyway, the PSU appears to be broken (I'll post more details on the main thread).

In spite of its excellent conditions, this #Plus4 does not power up at all 😭

The AC fuse in the PSU and the DC one on the motherboard aren't blown, so my next suspect is the "wedge" power-supply.

These PSUs made by #Commodore in the '80s are known to fail often. Sometimes, they even output higher voltages on the +5V line which powers ALL the chips on the board! 😱

But this isn't the case: the power LED is steady off, and I measured near 0 volts on VCC pins.

Yesterday I received a donation of #Commodore hardware from a childhood friend, including this lightly used #Plus4 in its original box, with perfectly preserved manuals.

@globalc lol, was this post meant to be published on theonion.com and the author accidentally used their work account? 😂

@toroidalcore Yeah, better luck next time!

Is it a scrub? The #NewGlenn countdown disappeared from the #BlueOrigin official livestream, with no comments (yet).

They keep delaying the countdown... Now T-30 minutes. When does the launch window close?

Found the perfect companion for my #Amiga 3000: this beautiful NEC MultiSync with a horizontal range of 31-110 kHz!

I pulled it from the basement of my house and tested it briefly: it still works, and the picture quality is perfect after degaussing the CRT and adjusting a few display controls ❤️

@ltning The first UNIX system I ever used was #NetBSD 0.9.

It ran on my #Amiga 4000/040 fully expanded to 16MB of Fast RAM + 2MB of Chip RAM ❤️

@jope @batteman AHA! It was in the release notes of intuition.library 48.3.

@jope @batteman Yes, I have actually seen the new floating menus of OS 3.3 long ago! I might even have photos to prove it!

@ij @jope @batteman I just recalled that some SCSI controllers implemented the TD64 device interface to handle large drives.

My HD images were all below 4GB though, so my WB partition got corrupted for a different reason.

@ij @jope @batteman I did not think of scanning the corrupt partition the new diskdoctor bundled with OS 3.2 to see if it would at least report a problem with the Tools directory.

Plus, #AmigaOS 3.2 integrates and obsoletes many other hacks I installed decades ago.

I still use TinyMeter and MagicMenu. Are there any actively developed alternatives for these?

I'm slowly catching up on 30 years of #Amiga development :amiga:

@batteman @jope

I also had three SFS partitions on my hard drives: Work, Store and BBS.

However, my RDB still contained the original SmartFilesystem 1.84, which couldn't mount the partitions and was likely the root cause of mysterious crashes of the "UAEDH0" task.

Many of my favorite #Amiga system tools are still in active development today: SFS, P96, DOpus5, ViNCEd, MCP, AmiSSL, MMULib...

@batteman @jope #retrocomputing

@dirkdierickx Indeed. Lots of new Amiga-related projects are derived from the AROS codebase, but somehow AROS itself never managed to replace the proginal AmigaOS.

Since I couldn't figure out what happened and how to repair the FFS directory structure, and re-transferred the #AmigaOS 3.2 system I normally use in UAE.

The problem never reappeared, so perhaps it was just FFS being prone to corruption when writes are interrupted by a crash. And this #Amiga was rebooted numerous times while I was chasing the remaining hardware and software stability issues.

Anyway, these are some of the joys and sorrows of #vintagecomputing ❤️
