This Olivetti PC128 definitely needed some general cleaning! (and a recap just to be safe) I’m glad the power switch issue was only mechanical and the tape deck belt was probably just loose from age. I’m a bit sad I couldn’t test the optical pen though. As soon as I get my hands on a CRT TV, I’ll update you on whether it works or not! (Sorry for the nasal voice and red nose lol, I still have a cold)

I shall be watching this as soon as I am home from work 😄 Undoubtedly, you can fix it 💪☺️🥰

I love how you often have items that I'm not familiar with, I am aware of the brand but not the computer so interesting to see something new again. Great video as always.

Very cool! I’ve never seen one of those before! If that power button breaks again-I’ll bet you could print a new one! I’m sure you couldn’t model that in CAD! Also-I love what you did with your hair! Very subtle and nice!

I mean this in the nicest way possible - you have the scraped up hands of a bench technician. I salute you!

Nice work Sayaka. It is always interesting to see the last minute fixes made to production designs, like that bypass cap which was added by hand to the bottom side of the main circuit board. We still have to do that sort of thing with modern products, though it is more common to update the design and fabricate new PCBs. I didn't realize that the PC128 also used the Motorola 6809E processor. That was what powered my first computer, a Tandy / Radio Shack Color Computer. I first learned assembly language programming on that by reading a book. The 6809 has a very nice and (relatively) high-level assembly language, and it was easier to program than some other 8/16-bit of that time period. With just a 16-bit address bus however, systems like the Olivetti needed to use bank-switching to address more than 64K of memory.

Got my scars in the PC trenches in the 90s. :)

*boink* 😁 The beauty is always in the details 🥰

I absolutely loved your early access video on bringing the Olivetti PC128 back to life! 🧡 Watching you carefully clean and restore such a vintage machine was so satisfying — every little detail showed how much care and passion you put into it. The power switch fix, the recap, even the note about the tape deck belt aging — it all made me smile. I also really appreciate that you still filmed even while you weren’t feeling 100%. That dedication means a lot. I can’t wait to see the follow-up once you get a CRT TV and test the optical pen — I’m genuinely curious to see if it works! Thanks for sharing such a cozy and inspiring piece of tech history. 💾✨

Are you looking for a specific model of CRT TV or just whatever you can find available? I have a 13" Sony PVM; the picture quality is very good and it is a nice balance between screen size and weight. Unfortunately prices have been driven quite high as the PVM and BVM series are very desirable for retro gaming.

Awesome job Sayaka! Thank you for the overlay pictures as they go far to teaching newbies. I too loved looking through the ram/rom to see what was in them, although I never found anything as cool as what you did.

It is obvious to me, that you enjoy working on these retro-tech gems and the rewards of making these projects work again! Work is not really work if you love what you are doing.

I’m mostly just looking for whatever I can find in good condition! PVMs are amazing, but yeah, the prices have really gone up lately 😅

Thank you so much! 🧡 That really means a lot to me. I love taking the time to bring these machines back to life, even if it’s a slow process sometimes. I can’t wait to test the optical pen too, it’ll be fun to see if it still works after all these years!

Watching the video back, it doesn’t look like it, but I really thought I’d hit the cartridge hard 🤣😰

Sayaka's Digital Attic

Thank you! I agree !! It’s always fascinating to spot those last-minute design tweaks, they tell a lot about how the system evolved, and yes, the Motorola 6809E is such a nice CPU! It’s really cool that it was also in your first computer

I’ll definitely keep the 3D printing idea in mind if it breaks again, that would actually be a fun little project. And thank you for the hair compliment too!!

I really enjoy showing lesser-known systems it’s always fun to share something new and a bit unusual
