As far as I know, there are no acids coming out from a leaked alkaline or zinc-carbon battery. It's actually potassium hydroxide in the case of Alkaline batteries (which may react to potassium carbonate on the air) or ammonium chloride in the case of older zinc-carbon batteries. Both are pretty strong bases which let metals and electronical components corrode; that's why many people think it's acid. So why is this important? Because you can actually use some household-acids like vinegar concentrate to dissolve the residues of the leakage, even when everything is completely corroded because of the leakage. In case of these battery contacts or springs, you may simply remove them from the case and put them into some household acid for a few hours. You could also use some paper towels and clean "attacked" parts of PCBs using some not-too-strong household acid. Of cource, this will not bring back completely destroyed traces of a PCB, so you should do this, before it happens. Simply scratching the leakage often isn't enough, since there will most likely always be some inivisible residues left. Luckily, in your case the leakage didn't seem to have attacked too much. Sorry, english is not my mother tongue. Hope I could help with this :)

+martravi Good to know. I have done the opposite and cleaned car battery terminals and such with baking soda, since those are actually acid. I assumed the alkaline batteries were too.. but now that I think about it, I guess that's why they are called alkaline batteries. I guess it is a "duh" moment.

I had one of these in early 1984 - it cost me £150. I'd just started working, and this was the first really expensive thing I ever bought. I used it for years, and very soon after I got it, stopped using the pre-set everything on it. The Multi-menu meant that you had a programmable drum machine, bassline, etc. I ran it through various effects pedals, and got it to make some nice dark crunchy sounds, which was great, as I was a fan of the 'darker end' of the electronic music spectrum (still am, actually), like Throbbing Gristle, Fad Gadget, D.A.F., Gary Numan, etc. Then I got rid of it. And, hearing it again, I wish I hadn't.

I bought one here in the UK in early 1984, and it cost £150. It's a brilliant keyboard, and once you have mastered the 'Multi Menu' function, with it's programmable drum machine and bassline, I very seldom went back to using the preset sounds. The tape dump worked pretty well, but wasn't very quick. It sounds fantastic if played through effects - I had a load of guitar fx pedals, and an old Tandy (Radio Shack) reverb unit. Alas!

Great cleanup job! You are correct that it's not FM. The MK-100 used digital waveform sample based synthesis. However, Yamaha was indeed using FM synthesis back when this came out, just not on their cheaper porasound lineup. For example, the MK-100 came out the same year (1983) as the most famous FM synth of all time, the DX7. Portasounds started using FM around 1985.

Wow, yeah, 7 bucks for this little beauty is a great bargain! Yes, a keyboard's only really yours once you've cleaned it. XD The MK-100 is one of my favourite keyboards from that time. I was happy to find it for 40€ ten years ago :) Lovely organ sound, great percussion, and loads of features that make this a real little workstation (rhythm sequencer, bass sequencer)... Tape storage was by the way noot that common feature for home keyboards with more complex sequencers in the early 1980s. Casio PT-30/31/50, CT-7000 all had it, even the CZ-5000. And yes, the first home keyboard with FM seems to be the high-end PS-6100 from 1984, with "standard" PortaSounds following in 1985. But... when's your in-depth review coming? ;)

I am really enjoying these videos. You do a great job of making them interesting and entertaining.

Pro-tip: Vinegar (acid) makes a wonderful cleaning agent for leaking alkaline (base) batteries. It's best to remove the batteries first and properly dispose of them. Putting leaking batteries directly into vinegar could lead to volatile results. Always take caution when mixing acids and bases.

4:30 ‘it’s actually pretty amazing’. I don’t know whether David always thinks thinks this and follows with ...’for a cheap 1980’s keyboard’ or whether he genuinely thinks it is amazing full-stop - even in 2019! I think a part of him never left the 80’s.

Wow this sound *really REALLY good* for 1983

The piano is really awesome, I could actually feel it vibrating in my floor

I can't see why Yamaha stopped using that technology. This keyboard sounds incredible!

Yamaha's Electone ME series used the same menusystem, but with more options, i had the ME50 back in the day, greets Levi

I loved these sounds as a kid and always wondered why the music industry stopped using them. Its sad, imho, that obsolescence seems to be a sufficient reason to turn your back on what feels good.

Impressive, you can actually play the keyboard well! Love your channel man.

7USD is unbelievable for this beautiful synth. Congratulations

That multi menu is so cool! I want one now.

I love your videos, dude. Great work!

I really like your videos. I'm not usually interested in synthesizers or such. But this is great.

The Rolodex-style Multi-Menu was originally used in the Yamaha Electone MC/MR series home organs, then the HS and HC/HE series. Both a great way to save space and a horrible idea. It made playing the Electone a much more complicated task.

This is still a great channel. Infant even the video runs smoothly on my iPad 1 which is quite rare for some videos.

This was my very first keyboard when I was 13 and I loved it. I then decided to get my first synth and traded the MK-100 for a Casio CZ-1000. When I sold the Casio, I then moved up to a Roland D-10 and then a Kawai K-4. Today, I still have the K-4, found the VST version of the CZ-1000... and was so happy to find the Yamaha MK-100 online a few years ago! After all, It was my first love! Thanks for the video. Great you got it cleaned up.

Wow what a fantastic price at $7. I really love these keyboard demos. You should do a video of you just playing different pieces.

How didn't I notice this channel before?! This is awesome XD I subbed

I used to have one of these and could not remember the model number. It's nice to know that it sounds as good as I remember!

That is a great keyboard. Nice sound too.

I have seen a custom rotating selector like that before. Back when I played the organ, it was on the late 1980s Baldwin home organ in my (parents) house. The features on the Baldwin were different, but the rotating selector was very similar.

nice job of restoring it.

I love, love, love, LOVE videos like this! I like seeing the whole process of how you bring things to life in an interesting way. Very interesting keyboard and in some ways maybe sounded more like the Casio models of that era? Hard to say but it definitely does not sound like FM.

The closest I can come to this era with ownership of anything electronic is a random MS-DOS era RAM stick, previously belonging to a computer my brother had for about a week before it sparked, let a puff of smoke out the ventilation holes, and never worked again. (can't remember what type or size this RAM stick is, but it uses flat pins like an NES cartridge as opposed to actual pin-shaped pins yet.)

@luisneitzke106

The PSS-450 is indeed the same "base" keyboard, but it lacks so many features that in the end it may not be worth it. Not only it lacks the synth section, but also all of the custom options (custom drummer, bass lines, accompaniment, dual voice, etc), trio mode, sequencer, transposer and even the tremolo and vibrato effects. It's a very basic keyboard, with only the main MK-100 voices and rhythms (including the three or so variations for bass and chords), just the essential effects (sustain and stereo symphonic/chorus) and duet mode. I'm not sure how much they cost over there in good ol' USA (and good ol' all over the world), but it would be wise not to pay much. It has some lovely sounds, but it's very basic. The MK-100 really has it all! Thanks for all your videos, by the way. I really appreciate your channel! PS.: A few days ago I asked here in the comment section if anyone was willing to sell a MK-100 so I could use it in my lo-fi projects and thankfully I found not only one but two of them! I'm really happy. I've been looking for it for a long time.

That's really cool to see the multi-menu on a smaller keyboard. Saw the same sort of multi-menu arrangement on a Yamaha Electone organ, specifically the model MC-200T.

+8-Bit Keys I haven't plugged this one in for a few months but my recollection is that you can't play the drums manually.

You can then play a new pattern for that individual part. You need to do that for all 5 drum parts. It's tedious but it works. The manual for this keyboard is still available on Yamaha's website which helps tremendously!

It cost £200 back in 1983, yes I'm British, I still have my MK-100 in the box with instructions, it was my first keyboard and it became part of the family.

Having a keyboard with interchangeable waveforms and being able to customise them is neat... Also I noticed button number 12 at 6:17 when selecting a waveform. I don't know if it's unused or has a function for the waveforms.
