oh thanks for sharing. I landed in this channel coz I got FX-840P in my online local shop for just 17 usd.

Incredible adventure. Yay for HC-80/PX-8

very good job!

Hi Jeff.About the CASIO FX-502P that was my first calculator (my dad passed it to me when I was 12 beginning high school) and yes, it's fully programmable and it came with a thick nicely printed manual containing listings for hundreds programs you could type in the calculator, then save it to cassette tape via the adapter.I remember it was even a "biorhythm" program that was kinda cool thing in the early 80s (inputting your birth date and current date and having a computer telling you how you'd feel LOL). It was one of the first scientific-engineering programmable pocket calculators in South America; and this one had the extra capability of composing music, using one of the overlays your received and making your own music cassette!.A truly vintage one of a kind.

To save on paper, use a 10" Tablet better; helps save nature Good job, your friend will be pleased, specially after months, he probably thought: it's too old, no parts, it's a gonner. I was thinking, to take any small dirt on the parts: Blower, or compressed air can, or small vacuum cleaner, then Ultrasonic Cleaning & WD-40 wash up

Hey Birt, I hope you see this comment, as I'm wondering about an aspect of your setup. I'm currently prepping to recreate your 12% H2O2 heat mat setup to do some retrobrighting of my own. I've got a similar setup; same size mat, roughly same size container, the only difference being that I'm using a 30 watt heat mat that has a maximum temperature setting of 45 degrees Celsius. I was wondering how close I could get to the 40 degrees, so I'm testing with tapwater. I've got a polystyrene base with a small sheet of aluminium insulation foil on top to reflect the heat back into the container. The container I've got covered with thick blankets to provide a little bit of insulation as well (not ideal, I know). I've got the heat mat set to 45 degrees, and put a temperature sensor in the water hooked up to a multimeter. After roughly 12 hours the water only gets up to 30-31 degrees with an ambient temperature of roughly 21 degrees. I double checked and the multimeter is accurate. So, for my question to you: I've gone over your video multiple times, as well as the data you've uploaded to OneDrive, but I cannot find if in your tests, by 'temperature', you're referring to the temperature you've got set on the heat mat, or if you've also got a temperature sensor in the hydrogen peroxide. Thanks in advance for answering! It's a really great and insightful video, and an awesome contribution to scientific research on this topic.

A masterful repair, young Skywalker!

Wow! Amazing work! This thing fascinates with its ability to create a directory on tape! I want that for my C64!

Bravo! Nice save! Amazing to me. PX-8 is a nifty computer.

FANTASTIC! NICE KIT

It is becoming increasingly difficult to obtain these computers in Japan. I am very surprised that there is such a wonderful collection so far away from Japan. My FX-860PVC/PB-100/Z-1 also has LCD problems and can no longer be repaired. I feel a little sad that there is no way to repair these. The back panel of the FX-860PVC states S-7 荷重計算 Load Calculation S-8 体積計算 Volume Calculation S-9 コスト計算 Cost Calculation It may have been used in places like construction sites. I enjoy watching your show every time. Thank you.

Hey Jeff! Careful in handling that equipment! Some of it is Sharp!

The Nagus would be pleased. Though his ears might not be with the tape.😁

It works, "Excellent!" Dig it

Looking forward to seeing that printer work!

Sorry, Birt, but Jumpman is *not* a game to test c64 video quality with! ;-) Try something with good graphics, expecially hires gfx with black! Head over Heels comes to mind f.ex., or Amaurote...

Hello. I am the guy that actually invented the c64 Svideo cable waaay back in 1996! ;-D /dk/crest

Practical question, these seem to have a German keyboard layout here in Belgium, and as I type blind, I loathe the swapped Y and Z. Can you pull the keycaps and remap them with a ROM mod? I don't mind the eu's and the ringel-S.

Very cool machine. Do you know anything about what you can pop in the 4 slots at the bottom. Two are filled in mine. I also have no idea how to set the clock.

Dr. Egon Spengler's pocket computer of choice. 😊

The CE-125 and a 1250/1260 was a really neat combo!

46:35 What's that button and spring for anyway? The service manual refers to it as an "earth knob"... 🤔 I have a CE-122 with major corrosion that couldn't be saved anymore, despite major cleanup. Too far gone.

I have a CoCo 1 and everything works but it has a black screen. I even installed a brand NOS RF modulator.

The C book is very expensive to buy - is put of print. I downloaded a well scanned pdf copy for free from somewhere, then printed and bound my own copy on 100 gsm Mellotex paper, at A4. It will last well beyond my own lifespan. ❤😊

I was in university in the 1990's, and I recall the textbook for a physiology course I took. At the end of the course, I went to the professor and told him that if he used the same textbook again, he should tell the students to ignore the first 3 1/2 chapters, because they were garbage. He told me he was writing hi own textbook. The one specific example I recall that shows the problems with the book is that it had at least the professors as authors, and at least three editors. And between them, they didn't know the difference between mass and weight. There was a place where they gave kilograms as the unit of weight. (A kilogram is a unit of mass, the correct unit for weight in metric is the Newton.)

K&R brings back lots of lots of memories. I had the white cover version. Great video as always.

I have a book for chip reference its very useful

One of my professors retired while I was in college for EE. I snagged a bunch of really cool old books on computer engineering and tube circuit design. I still have them.

Sure wish I could get a BPD+ for my Tandy Model 102. Do you have any idea when they will be available again?

I totally agree with your opinion. The information in yesterday's books were much better than what's available today. Not only was the content better, also people cared about correct spelling, grammar, and diction. Today I shake my head at how bad writing has become.

FREE, like in the land of the FREE, not in the way of a FREE lunch, for old book you have to pay to get them. Some useful books cost a fortune and are only available in PDF in the store of some monopolistic merchant of scanned books.

I have some stunning old books - and even some interesting PDFs of 100 year old books - the language reveals so much about attitudes of the time... Reading them is a joy - like travelling in time... 🙂

Old manuals and books are awesome. I found "Metals and how to weld them" that someone threw out. I'm not a welder by trade but it is full of all kinds of useful information.

Great books! Thanks for sharing this collection.

I love vintage and antique books!

Excellent collection!!

Now I'm jealous! I do have quite a lot of electronic books from early '70s but those are really difficult to find here in EU in recent years!

The Kernighan Ritchie is „the“ C language book. I use mine quite often, because I sometimes have to look up something, that I rarely use in my „normal“ microcontroller programming. Unfortunately, I have the German version of the book, which sometimes gets lost in translation, a bit. Actually, American text books are my favorite, because they are usually, like you say, getting to the point. German text books are usually not that way. They are written in a pretty abstract way and one has to get along with long and complex sentences. I always hated to read the books from my professors about their lectures.

What a treasure trove! ❤

Thanks for the Tutorial. Added to my Calcs Playlist. Sorry about the passing of your friend, stay healthy

Do you sell those Casio VX-4 or why do you repair them?

Totally agree about the Kernighan and Ritchie C book, I have one as well.

I have CE516P, I dumped the ROMs and did little bit of reverse engineering (e.g. what is connected to which MCU port). I also have 3 or 4 of Mera Poltik's "clones" of CE515P, the MDG-1/MDG-116 (they were based on the Z80 though, not on the Hitachi's version of Motorola's 6803).

This is an awesome piece of kit. I had a VIC 20 with a loose and rattly case, and several parts broke when I tried to insert a cartridge. The case saver was easy to install following these instructions and now the VIC feels solid as a brick! Awesome stuff and super cost-effective. I’m new to Commodore computers and vintage computing in general. I have been taking a deep dive into this channel, trying to glean as much information as I can. Great stuff and keep it up!

39:45 - Bleaching your socks rapidly accelerates the breakdown of the fibers in exactly the same way it brightens them. You're literally arguing that a single bonded molecule isn't significantly weaker than a double bonded one. I have a pile of shirts with bleach holes in them that I'd like to offer up as evidence to the contrary. Overall, a very informative and interesting video, but don't underplay the weakening effect of bleaching action on plastics. On ABS, it's not nearly as noticable because ABS is already so tough, but it will totally embrittle nylon, acrylics as well as vinyl compounds and many others.

Old man glasses.... HEY! I resemble that remark! ha ha From one old nerdy fart to another. Nice video. I fixed a lot of video games in the late 80's and 90's. Later video poker machines for the mob in bars LOL and cable descramblers with my trusty eprom programmer. Thanks for sharing. God bless. The KlodFather.

I think if you mix a little baking soda and water, and use a q-tip to apply, drip a tiny bit of the solution onto the superglue, you'll get a faster cure and a stronger bond. (Do it after the piece is in place where you want it, or the glue might cure right away.)

Nicely done!

Those machines are so coool! I think they would be successful nowadays, too.

Very cool! And, thanks for gathering those links (although at least one of them has since moved -- the YACM site -- it's still up at a new address). They should be helpful to me (when I get the time), as I got one of these fascinating little machines second-hand (and, thankfully, already restored), myself.
