I have two 840AVs, both require heavy restoration and one is missing its CPU. 🙁

@Horun: The 840AV is one of the most valuable retail Macs (not counting the special/limited editions). A working mainboard easily sells for 100 bucks or more. Keep that in mind before giving it away and then finding it on ebay the next day.

Thanks, I do not plan on giving it away unless it will not fit in the other case (from a 8100, looks same) or one I stumble on for very cheap. Also the PSU is shot. Cat piss ! Yes I should have wrapped it in plastic or put in a box instead of just sitting on the garage floor. Guess I can take one from a 7300/7500 and rewire it......

My cap replacement order (for a PSU) was canceled, they ran out of stock. So went to Digikey and ordered from them. So am replacing the crappy Fuhjyyu TM with Nichicon brand but different part numbers than oredered before. Getting these: UPA1C222MHD3TO and UPA1C332MHD. Not as low ESR as wanted but still good low impedence and good Amps/ripple. The PSU needs 2- 2200 and 4-3300 so ordered double that 😁
Any comments or advice on if I should have ordered a different bunch please let me know.

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣

Emulates floppy head seek, read and write sounds.

Please put up a sound or video of this!

On another note, spent several hours trying to get an INNODISK 44 pin Embedded Disk working in an Armada 1750 as well as though adapters (carefully observing PIN 1 and VCC) nothing - no dice, it actually kills whatever's on the IDE channel. 🙁 (as in, disables it completely until the Innodisk is removed)

CF to IDE is going to be the next experiment, I'm trying to revive an LTE ELITE 4/75CX, which ALSO has a broken band in the floppy, but I have some experience with that as I re-banded my 4/25 LTE.

Installed Windows 98SE on an Asrock 775i65g with a Pentium E5800 LGA775 3.2 GHz CPU manufactured in 2010.

Board has an AGP slot too.

put the finishing touches on my pentium 4, 5950 ultra build.
installed all the fans and added another dvd burner just because.
and of course, the most important part, the pentium 4 sticker 😎
this ones all ready to go back in the box.

I just used Wineskin Winery again to play another favorite of late 90's / early 2000's: Championship Manager 3. This time running "natively" on macOS Catalina thanks to wine!

I'm looking forward to porting more of my old games from my Windows 2000 VM to my mac. I just ported CM3 and and also got Counter-Strike 1.6 as well as GTR Evolution (RACE07) working, the last two came from a Steam app for windows I ported too.

I only failed with rFactor 2 - I can get to the game launcher, but it crashes when I try to run the game from there. I bet I can get rFactor 1 working.

Next on my list should definitely be Flight Simulator 98. I could try 2000 or 2004, but I don't remember playing them (maybe 2000, I remember having the box).

And I've also got Grand Prix 4 working (and faster than my Windows 7 VM!!!!), but only in its "pure" condition. I also want to play the mods of past F1 seasons I have, but the editors for the game aren't working thanks to stupid Apple and its notarization of apps. I've left it to the VM for now. This can be the end of gaming on virtual machines for me! yay.

So dragged the system back home, thoroughly cleaned it (filthy :r ), replaced the old T2300 and interesting So479 motherboard with a Gigabyte GA-G31M-S2L.

It may be 12 years old, but with aforementioned Core2Quad and 4GB of RAM it should be more than capable of handling the occasional word processing and frequent Facebook trolling that my brother gets up to. Then inserted a trusty old Intel 120GB SSD, stuck in a freshly-made official Windows 10 boot USB and... no boot. Turns out UEFI support is compulsory now for the USB media. Shit. Then set about migrating the existing Windows 7 install to the SSD. Pain in the rear-end, but managed that. So tried to upgrade (still possible from Windows 7 to 10). After a lot of mess, complete fail - the infamous 0xc1900101-0x30017 error. Something went wrong before boot. After ruling out various other software things, what's left sounds like BIOS issues (possible lack of UEFI, GPT or secure boot) again.

Yep, a C2Q system is now too old to be allowed to run Windows 10, so despite multiple cores and RAM support still outclassing low-end new stuff, it's officially retro in the nastiest way 🙁

So, you got youself a nice SO479 motherboard from that 😁

A friend of mine runs Win10 on a C2Q, all though a 9550. The 8200 does not support Virtualization it seems. Might this be an issue for Win10?

Quite a productive day today. Dusted out the Zenith Z286LP Plus. Got the lpt port BackPack CDROM drive functioning and to my surprise it handles CD-RWs. Found a suitable network card to fit in my Restone XT Turbo system. Tested a few older hard drives on my K6-2 266 test rig.

There's a glitch in the matrix.

Got the Gotek working as an external boot drive on my A500. I put the selector switch in my trap door area. It works! Motherboard is Rev 6A, first time it has been opened -- I broke the warranty seal. The only issue I see so far is the mouse only wants to move horizontal.. have to troubleshoot that next.

Haha, I was looking into that, or building one. I ordered an optical assembly for replacing the tank mouse innards. I was very tempted to do the accelerator as well. 😜

Recapped my MAXI Studio. The original caps were damaged when I got it, and they were from GSC.
It took about 4 months to finish this as everything had to be done in spare time.

Few tips for those looking into recapping the maxi.

  • A Hotair station is your best friend. Few through-holes holding some critical caps have the largest ground plate I've ever seen so far. Daymn.
  • I used Nichicon KT series which happens to be 5mm in diameter (1mm larger than the original) and 12.5mm in height (2.5mm taller). It fits right in w/o any problem whatsoever. Other caps in the similar size are... well, you just need to look it up.
  • C82 needs to be bent in 90 deg. It interferes with memory.

Here's my capacitor map.

The final difference in sound? Not so much other than the fact that the new caps would last forever.

* EDIT : The old GSC cap is 10mm tall, and Nichicon is 12.5mm in height.

I'm having that same mouse movement problem intermitantly with my A1200. Pushing down on a connector plugged into the mouse port or joystick port allows its use correctly. Also when disassembled putting some pressure where those 3 stickers are on the motherboard near the connectors allows its proper function as well. I tried to resolder the connector to the port but that didn't work. Let me know if you discover what the issue is as it might help me fix my issue. On the 500 you can swap the CIA chips around to see if its a problem with the CIA chips, but the 1200 doesn't have the same configuration to do that...

Today's retro activity was just cleaning & fixing a 3rd party SNES controller, which had an erratic D-PAD.

Opened it all up and cleaned with isopropyl alcohol.

And now back together and working fine, being tested on Fifa International Soccer.

It's not a great controller by any means, but it's functioning correctly now and will suffice as a 2nd player pad. It's certainly easier on the hands than those cheap Trixes SNES controllers that are all over eBay.

I think mine is an issue with the mouse itself. If I move the y-axis wheel, it will move about 2 pixels and bounce back. Likely the photo diodes in the mouse failing, which is pretty common. Jiggling the port or pressing on the board/connector does nothing. I can test the serial port with a serial->ps2 Amiga adapter I have. Regardless, I ordered a tank mouse optical conversion kit.

Next step: Order an expensive accelerator.

TF-534 or VampireV2 are two good ones.
