Drop me a DM, I may be able to help.

Ouch! :mad: You mentioned you've replaced the oscillator - maybe try a 40Mhz one? Might be cheaper than finding a faster CPU - and would be useful to know if that makes any difference?

Yes, that's my understanding. I couldn't remember what exactly was on mine, so pulled it out for a pic : As you can see, I too have a 50Mhz FPU, but only a 40Mhz CPU! :cautious: As for stability, I haven't run it in anger, but I do wonder if heat would be an issue since the CPU / FPU would...

FWIW, I have a similar one [SIMM sockets are on the same side as the CPU/FPU] that had damage to the "gold labels" on the CPU and FPU - so I pulled them off. Guess what - neither were 50Mhz parts. Shame on you MicroMac! :confused:

Welcome to the community. This has been discussed recently: https://68kmla.org/bb/index.php?threads/making-disks-for-the-lisa-400k-drive.46647/ ...and you might find this useful as well: https://lisalist2.com/index.php?topic=121.0

FWIW, there's a real live one on eBay atm -- https://www.ebay.com/itm/196240041576

I've seen worse :cry: - https://68kmla.org/bb/index.php?threads/warning-exploding-maxell-pram-batteries.25169/post-475409

9 chips usually means 'with Parity' and '-60' would mean 60ns parts. Pictures or what you need them for would help.

Ooo... nice & congrats! Will they be going in sale somewhere/time? 🙂

Not sure they are interchangeable? Perhaps someone following this thread will know? 🤔

Bummer. I have had to replace the "power in" (DC jack) board on one of mine. Not sure if this is the exact one, but similar to this :

Disconnect the PRAM battery and try to power it up? https://www.ifixit.com/Wiki/PowerBook_G3_Pismo_Troubleshooting#:~:text=Bad%20PRAM%20Battery,-If%20your%20computer&text=This%20is%20easy%20to%20test,then%20replace%20the%20PRAM%20battery.

What about using a solder-type DB-15 that you solder to pads on either side of the PCB?

If you are talking about the Macintosh Classic, then, yes, you can change the voltage. I have converted a 240V board to 120V, and the opposite should be possible. I found the artached post in an old newsgroup that I used as a guide.

Um... the battery is external to the logic board on a Plus.

Wow, just wow! Amazing work! :cool:

No worries, just wanted to make sure any new "converts" have a positive experience! :)

Needs to be American "billiard" size, which is 2 1/4" for the early Kensingtons. American "pool" size is 2" = too small.

For anyone in the UK - these can be had here -- https://www.clubking.co.uk/shop/snooker-and-pool/spare-balls/black-no.8-ball-standard-2-1/4-inch.html. I've ordered a couple and they work great! :)
