So yeah, the conductive ink got somewhat conductive (about 400 ohms, which I find a bit high but well), and it worked.

If you want to see if the keyboard got fixed: https://youtube.com/live/aZ1rp5uP32s

Turns out there's a cut trace on the membrane. I tried conductive ink but it didn't work, I'll see tomorrow if it just needed to dry out.

Let's reassemble the keyboard on that #eMate ! https://youtube.com/live/y6ntLRxJCCk

I got the touch screen working on today's stream: https://youtube.com/live/ZUPeucoKURc I torn down the keyboard to clean it up, it's drying now:

So, one spring broke after I added the washer. I suppose that washer was a bit too large and so didn't push the spring inside the cavity properly… Or maybe it just needed more grease… I added a smaller washer under that one for good measure.

Let's work on that some more on a live stream: https://youtube.com/live/BHuCcFBdOKU

I got distracted because… because people :mad: Today I cleaned up the bottom case on Dave's stream: Still needs a lot of work, but I made sure it's working. Just the touch screen doesn't yet, but the screen ribbon needs more cleaning due to spillage.

Like new from factory, but I'll need to fix that :)

I acquired a second eMate recently, and this one needs a bit more work than the previous one… First, it needs a good clean and has some rust in places… I'll handle that later, first I had to fix that burnt zener diode that shorts the power input. Likely a protection diode (12V when the input...

Well yeah then it's logical than the larger RAM, the slower it gets on average, if more of it is in the one waitstate section. It doesn't explain the slowdown for only 4MB though…

Having more chips on the card increases the current pulled on the bus and likely the access latency, but likely not by that amount, and unless the chipset compensates for this programmatically it shouldn't see anything actually… IIRC these are synchronous, so it's not like they reply when the...

Its working fine btw, though the hammer method is probably not a great idea, if anyone tries heating, let us know!

We have this EMU Graphic Equaliser here that are missing the knobs on the gain pots, and one of the pots actually has a broken axis, and it has an unusual diameter of 4mm. So instead of searching for replacement pots that would probably require me to drill a larger hole in the face plate, I...

There's no reason not to have both option if the model is done properly, as I did for the 5xx ones.
