Well... that took W A Y longer than planned! :rolleyes: However, I can now confirm that the ROM I posted a pic of is indeed a Rev.A. Bummer. I did, however, pull the ROMs from all my beige G3s and can add the following info to the database... Firstly, a "WRAITH ROM" from one of my G3 MTs ...

also on my list - take an accurate measurement and see if there's an off-the-shelf bit of ali channel with a close enough inner dimension... 🤔

Yeah, I've been thinking along these lines for the longer-term. Will let you know how the testing goes. (that said, I expect it will work since I'd previously used a smaller clamp to confirm the instability was down to the splitting connector)

Believe it or not... haven't had a chance to test yet. 😞 Life threw some serious curveballs which put Mac-time on hold for most of May/June. Just getting back to a few projects - including this - that were back-burnered. Visibly, the repair went well - just need to drop a CPU in and check...

Confirmed!! Here's my card : Thank you @Carlito for showing us the way!

I've NO idea what the chip is on the extreme left end, and the pic is a bit blurry... but those pins near the hole above the "208" look pretty close together... Worth a good inspection?

I thought there was something familiar about your card... Not sure how much help it'll be over here across the pond. I also see some buldging on my PLCC socket, but I've not had any issues so leaving it alone.

I think I might have that same card. It's late here, so will have to ck tomorrow.

-- edit -- Have you tried removing/re-seating the RAMDAC? Could be dirty contacts?

That's great. I did say "I don't believe..." no need to be aggressive. Where can these cards be acquired? I didn't see them on the VintageMicros site?

@Berenod - I had 5 x of Alex's 2/5 motherboard made up, so I can spare one if you're interested. Also, I believe a 2/10 chassis can be converted to a 2/5 if you swap the internal wiring.

A link to @AlexTheCat123's work -- https://github.com/alexthecat123/Lisa-PCBs

I don't believe the 2/10 motherboard & I/O boards have been recreated? The CPU and RAM boards are the same between the two models, but the I/O board is specific to the motherboard and the 2/5 motherboard won't fit a 2/10 chassis and vice versa.

That's exactly it... patience (and persistence) and I've usually been able to get good results. It's also a case of the more you do, the more you get the hang of it. It's a bit of a black art, but worth it IMO. 😀

I've had pretty good luck on the few I've needed to "straighten" out. It is a mind-bender, though, with each magnet affecting the others nearby. 😵‍💫 I wonder if many of the badly off ones you find on the various marketplaces are the result of "frankenstein" reconstructions? 🤔

Can you share the incantation? I've so far not been able to make that work - but I've not spent serious time on it yet.

Ooo... are you gonna upload that as well? 😀

@max1zzz - see the macrumors post above - now that you have a G3MT - something to experiment with? 🤔

Sounds like a job for @croissantking! :D

Wish you'd gotten back sooner... it's back together now. 😞
