It is not pointless at all. First, it worked. Second, it shows how much of a beating old tech could take and survive. Oh, and thanks for another great video!

Hi Jan, Greetz from Canada! I had one of these in my A500 back in the day.

Wonderful. A "Jan Beta Was Here" signature under the clear coating in the corroded area would have been nice ;-)

I was amazed that there were no battery damage on my 501 when I took my 500 out of storage 2019, after more than 20 years in the box. The battery had leaked but the box was upside down all those years so nothing of the gunk had reached the pcb. I just removed it and soldered on a button cell holder and it's kept the time ever since.

That's the shiniest trapdoor expansion I've seen since the 90's! (Ohh, until the shielding came off, anyway. Poor thing.)

Hui.... ECHT mutig den Klumpen Kupfer in den Amiga zu stecken ;D Es haetten sich ja auch Kurzschluesse am Connector ergeben koennen :) Aber krass cool, dass SlowMem noch funzt!

Well done, I used to have one too but I suppose nothing lasts forever ...Ni ce memories though. I wish I still had all my old computers ( Vic 20, C64, Atari 400, A500,A1200 ) but I don't . I think some even ended up in the bin ... I have re brought them - but not the same, for 2 reasons...1st - they weren't mine and 2nd I tried to recreate a moment in time ... I never managed it

I love how you put down that painting surface, then just held the board up and sprayed it all over your oscilloscope 😆 Regarding fibreglass vs glass fibre, both are perfectly acceptable! For a little more context, in English fibreglass is generally treated as a mass noun with glass fibre(s) being for singular (or small-countable) instances. So that's why you get arguments about which term to use for the pen - are we referring to the bundle of hundreds of fibres _in_ the pen, or just to the pen itself? So yeah, both are fine. How are you liking those Adam Audio speakers, by the way? They're the base model, right? I've been thinking about moving-on from relying on headphones for monitoring, and wanted something more precise and punchy than your casual-listening 1.1 bookshelf speaker. (I also saw they came out with those tiny self-powered ones, but given the size I imagine those'd have annoying resonance in certain frequencies.)

I would be tempted to recreate the clock circuit on some protoboard and mount it as a daughterboard to the main memory expansion board. Feasible?

Great video, I hate making more e waste, and i like the distressed but working look, obviously if any sign of failure I would just reuse the chips on a new board though but cool nonetheless

Great Scott! Jan, you’ve really traveled back to the future with this one, haven’t you? Working on a relic from 1987, the golden age of computing, but also the dark age of leaky batteries! Your A500 memory expansion-it's a fascinating piece of history, yet like many things from that time, it suffers from the wear and tear of time travel, I mean, corrosion. But what you’ve done here is akin to pulling a DeLorean out of the junkyard and getting it to 88 mph again. Carefully neutralizing that alkaline battery leakage, meticulously restoring traces-it's like tuning a flux capacitor! Not to mention your decision to ditch the real-time clock. Let’s face it, who needs to know the time when you’re busy hurtling through different eras in style? Now, I have to admit, Commodore's soldered-shut design? Not exactly the pinnacle of foresight. Kind of like trying to lock the plutonium chamber-only to realize you might need to get back in there! And while I applaud your efforts in scrubbing down the corrosion, using white vinegar and a fiberglass pen, you’ve done something most people wouldn’t even bother with-restoring a piece of hardware that, in theory, you could just replace. You didn’t just repair an expansion board; you preserved a piece of history. And now, with that shiny conformal coating, this thing’s ready for whatever the space-time continuum throws at it. A job well done, Jan! Now, if only we could get a Mr. Fusion hooked up to that Amiga… you'd never run out of power! Keep up the good work, and remember: **The future is what you make it**-but I think you already know that!

Kinda silly that computer manufacturers couldn't figure out using better and safer battery technologies. Lithium coin cells were used inside game catridges to keep time and save data already back then.

They picked this because it was rechargeable and even non-rechargeable lithium cells were expensive in the 80's, rechargeable ones were absurdly expensive. And this leak problem did result in change, though for a large part it was "solved" with the Dallas clock modules that are a pain now too.

@@Nukle0n Game console manufactures could afford putting lithium cells inside individual game catridges and these weren't rechargeable either. Also these lithium cells last a long time. It's not a big deal changing them once in several years.

@@JendaLinda RTC modules drain a lot faster than something just for keeping SRAM alive, as can be seen from how all the Pokemon games with clocks have drained faster than all the others. But yes with the price of computers being so exorbitant you would assume it would be possible for them to pay the cost. But that's business, you cut costs where possible to make a larger profit and nobody at the time cared.

Would remove all the components and put it on a new PCB from pcbway. Wouldnt use that pcb again.. Its to far gone.
