I never had such a computer so very nice to see you make it work again. MSX could have been the standard to rule the world - but then came other computers and eventually PC. ;) You are the expert. This power board was a really nasty one. Many thanks for excellent entertainment one more time.

[@jumhig]

Nice fix. I've done some repairs on cracked boards, and i superglue plastic "ribs" to the board afterwards to prevent the board from flexing.

[@djpirtu2]

My first ever computer, SVI-728. Got it somewhere 1986 summer if I remember right... Had one game with it, Mopiranger module.

[@watchmakerful]

To fix all the traces along a crack, first take a marker and draw a line along the whole crack, then fix every trace intersecting that line. And always do this with all components removed from the board. Also if the crack is extremely long, it can be easier to split the board into two parts, prepare all the traces, then glue it back.

[@miked4377]

i like the msx disk drive and joystick you have plus the games you have very nice!

[@Arcticretro]

Ok, thanks!

[@Breakfast_of_Champions]

A replacement board design could or should be available, but that's a huge project.

[@ahmad-murery]

It's always good to see another MSX machine being salvaged. Thanks Tommy!

[@Arcticretro]

You bet!

[@yucelbilik]

We'd like to see more footage of Norway. Very nice video, thanks ❤

[@Arcticretro]

Thanks you. I have another channel with drone videos. Search for "Tommy Ovesen"

[@yucelbilik]

I watched them all. They are very beautiful. Thank you very much.❤

[@jasmijndekkers]

Hi Tommy. Nice begin of a repair of this MSX computer. I have a lot of these machines and have them repaired. Now they work great again. I wil looking forward for your new video. Greetings from Steven from the Netherlands

[@Arcticretro]

Thank you very much!

[@snowysnowdon5584]

Nice work Tommy. 👍

[@Arcticretro]

Thank you! Cheers!

[@frostykyogre]

6:34 after MSX 2+ there was MSX Turbo R, only Panasonic made any widely available units (supposedly there were some bespoke machines tailored to customer needs such as a car auction computer). I believe the short of it is that sales were dwindling for MSX and even though a MSX 3 was drafted most manufacturers pulled out, Panasonic wanted to keep making MSX computers so they introduced the upgraded Turbo R standard and went on to make only 2 machines.

[@networkg]

God jul Tommy and all Artic Retro fans.

[@Arcticretro]

Got jul!

[@BigBadBench]

That poor board! Impressive effort!

[@Arcticretro]

Yes, thanks

[@bonno666]

What a nice gift, but what a project. Someone probably smashed very hard on the keyboard. That also might explain the broken keys.

[@Arcticretro]

Maybe

[@RBRetroBunker]

Ohhh sorry Tommy i didnt know it was so bad chape. 😢

[@Arcticretro]

Thanks ok, makes it more challenging :)

[@miked4377]

i love msx tommy ! i will wait for the next one!

[@Arcticretro]

Next year :)

[@terosaarela4555]

I had a 728 with a black screen too about 20 years ago. Now, I probably would be able to repair it, but back then I sadly didn’t have the skills or equipment.

[@madigorfkgoogle9349]

wait, you didnt have the idea to search the youtube for fixing tutorial? Hmmmm...

[@terosaarela4555]

@ KZbin was founded in 2005, one year after I had the 728. I did ask around at forums.

[@madigorfkgoogle9349]

@@terosaarela4555 you dont have much of a sense for humor, do you? That was the irony in it, back then we had to work hard to find out solutions to our problems, read some books, get magazines regularly and ask around. Unlike today when we simply go to youtube and find many video solution for our problems, so even a monkey would be able to fix it.

[@madigorfkgoogle9349]

@@terosaarela4555 wow, so my comment got removed for no reason, thank you youtube.

[@andrewdunbar828]

I might be wrong but I seem to recall the Spectravideo came out before the MSX and wasn't exactly one but the MSX machines were very very similar to it.

[@Arcticretro]

Yes. I think so. The first ones where almost MSX compatible. Very similar. But still, you could not use MSX software.

[@JoCrt]

Great video and result

[@ghosthuntergr]

You can replace the 9929 with the pico9918 that produces vga output

[@Arcticretro]

Looking into that.

[@tenminutetokyo2643]

That has the same RF modulator as the TRS-80 CoCo 1.

[@Arcticretro]

Ok, thanks!

[@AK-vx4dy]

I don't rember exactly but 728 or 738 was almost my first computer, somewhat dream from computet magaizne... but wasn't

[@RobertoMartinez-lj4qx]

que desastre arreglando esa placa

[@hollgo626]

All These cracks and broken components, i would get a meanwell rpt 60 and rewire the Video circuitry rather than fiddoing around with the old Power Board...

[@Arcticretro]

Exactly what I will do

[@lifeisrealactiva05]

❤❤❤❤❤❤❤❤🎉🎉🎉

[@horusfalcon]

You might get with Noel Llopis (Noel's Retro Lab). He's something of an expert on SpectraVideo equipment. His video on the SVI-728 is at: kzbin.info/www/bejne/gZ3OkJ-Oaqaoj8k When there are large cracks that may not seal or mate properly, baking soda sprinkled over the CA glue can accelerate curing. You might experiment with it on non-critical PCBs first, just to get a feel for how it works .

[@Arcticretro]

Thanks. I already know Noel. Might ask him

[@EgoShredder]

Missing keycaps? Maybe have a word with Sayaka on her channel. She recently interviewed in person Kazuhiko Nishi, the man behind the MSX kzbin.info/www/bejne/m5nKlmahnLhkjdk

[@Arcticretro]

Ok! He still has keycaps ? :-)

[@EgoShredder]

@@Arcticretro She also has a 3D printer and went to a festival devoted to that recently. So yeah, she might be able to help you! I do not know if MSX guy has spares, but you never know.

[@madigorfkgoogle9349]

he must be like 100 years old, I think he was old already when he worked on MSX back then.
