Spezi is a softdrink in Germany, Even the colors match with the old colors from the 80s Spezi bottles. This Rom was a homebrew „Hack“ of the Speed DOS ROM.
Ha, nice catch, I thought it was a "Spezial" shortened and a hacked one, but I didn't think of Spezi. Are there archives and documentations? And for people not knowing Spezi: www.erinnerstdudich.de/wp-content/uploads/2020/12/400px-Spezi_bottle.jpg
I'd like to add that the word Spezi is much older than the invention of the drink. I'ts used to describe a close friend specially in the Bavarian and Austrian area.

Hey Adrian, the 6526A’s are fully compatible with the 6526’s (and 6526R4’s), the main difference is the A variant is rated for 1MHz. 6526B’s are rated for 2MHz and I believe the B’s are commonly found in the Commodore 128.
@nine there’s actually another variant that starts with the 85xx, that was intended, I think, for the C64c. I have one in a short board I have. I think it’s an 8502R0 or something similar.
@nine no, not the 8520. Yes, that was the part number for the Amiga CIA, but this part number was very similar. I’ll have to dig out that board and look at it in a little bit. Pretty sure is was 8502R0.
@@bretttesdall2155 The 8520 is the HMOS version of the CIA with a different TOD clock. The HMOS version of the 6526 is called the 8521 but most of the time it comes with the 6526 label and a subtle 216A sub label.
Its amazing the amount of boards one person can amass over time. Have fun at the repair a thon. I do like your methodical approach to testing these boards.
That is a C-64 board motherlode! You have the coolest, most generous viewers. It kinda made my week hearing that there will be another C-64 Repair-a-thon in the near future. I'm addicted to those Repair-a-thons. I can't solder worth a darn, so it is so cool to be a fly on the wall to your repair and diagnostic vids. Have a stellar week, Adrian.
Love watching your videos. I have learn so much. Got me through being stuck at home through this pandemic. By having something to look forward to watching.
@@rockapartie Apparently there are slightly bizarre "confectionary eating disorders" as I once knew somebody who loved Twix but always gnawed off the chocolate/caramel topping first. Finally, after the biscuit was "clean", he proceeded to eat it. When I asked him about it he said he didn't like the biscuit...
Opinions from a repair tech… if board number 1 is in fact burnt, I would scavenge the rare parts and e-waste the rest of the board. Burn damage usually results in carbon tracks between adjacent pins and in some cases excess heat causes the fiberglass layers in the board to separate, reducing the long term reliability. I would also suggest taking resistance readings of both rails on known good boards and then using that as a benchmark test before powering up any board to be tested. Also an infrared camera may be a good idea to spot abnormally hot chips when troubleshooting a dead board.
I remember back in the 80s in our classroom all 64-buddies had a modified ROM, custom color scheme, speed dos, turbo tape, custom keys, etc. I can still smell the odors of the old UV-lamp (that Mom usually used for bronzing) I've used to erase the EPROMs.
I've got a German friend who sends me a big box of treats and sweets every Christmas. Those Toffifee are my absolute favorites. Holy crap, they're so good.
Since these are caseless, checking out some after market replacement cases could be a cool end to the repairathon. I'd love to see all of them lined up with unique looks!
In Germany "Spezi" is a humorous term for "specialist/expert" or "special/custom" - someone or something is kind of special in the meaning of better than usual.
For straightening pins, maybe try putting the tip of a mechanical pencil over it and bend it back into place. Have tried that with CPU pins and works wonders!
A few months ago I got a brand new in box C64 plus 1541, never used, just tested once and put back into its box, still had the protective foil on the space bar. That thing was made in '85 and it was the variant in 9:38 and it did have the heatsink on. Made in UK. I had a C64 with an LSD PLA as well - all the colors were flashing all the time, machine wouldn't boot though. I kept the PLA because I found it kinda funny. And short boards with burning hot RAM, I had one and a friend of mine had one. He's like "why is the 5V rail only 3.8V? My PSU is known good." Then he noticed the immense radiation coming from the RAM chips.
Toffifee is available in Canada for awhile since the time I immigrated to Mississauga, Canada in 2001. You can get them at No frills or Walmart. It’s so big in Dubai where I grew up I used to get them as gifts lol. One of my favs. I like to microwave them for 5-8sec to get them all gooey 🤤
Spezi, German, short for spezial or speziell meaning special. There's a beverage in Germany which is called Spezi. Spezi also means friend, short for special friend, i guess. It's pronounced spehtsee. So Spezi System could be understood as a special System or as a Friend's System. That's my half educated guess. It could also be understood as a specialist's System, maybe, but don't quote me on that ;-)
The "special friend" meaning of Spezi is mostly (only?) used in Bavaria, the southern part of Germany. This could be a clue about the person making it.
When I grew up in northern Germany (around the time of the C64), "Spezi" was actually a derogatory term for a dim-witted person. I took "Spezi-System" as self-deprecating humor by the author.
The C-64 scene was very active in Germany. There were many homebrew mods done and this "spezi system" might just be somebody modding the copyright notice to something more to their liking. Like another comment mentioned, it is also the start of the word "speziell" (=special) but I've never seen anybody abreviate it like that, so that seems unlikely. Given that "Amiga" means "Friend" and that was a well known in-joke at the time, it might be somebody's idea of a "backport", if only in words. Kind of like "Amiga OS" only in German slang. The "FREI" instead of "FREE" indicates that the intro message is supposed to be German. German Google also only sees lots of "specialists" and "special parts" related to the C64, so it doesn't seem to be common...
I always loved the Commodore 64 and all of it's variants. I had a total of 4 different machines; C64, 64-C, 128, & 128D, along with the 1541, 1571, & 1581 drives, and other attachments. My father has them now and I would like to get them all back if he wants to let go of them. All I can say is keep them 64's (& 128's) running
For bending pins back into shape, you can take a .05" or .07" mechanical pencil, take the lead out and slip the pin backwards into the pencil then use it to lever the pin into shape.
25:11 You borrow a fuse for #7, and start to turn it on. I'm half expecting the fuse to blow, you click the switch and everything goes black! Made me laugh, thanks.
Believe it or not, the short board will boot fine without the fuse in. But you won't get any sound and a few other things probably don't work. But it will boot just fine.
@@RayBrooks0 Haha, so you mean beer with cola? :D Yes, mezzo mix is called "spezi" here. Didn't know that mezzo mix is not a local product only for germany...
@@BilisNegra I had a Spanish friend in London, she taught me about it. Also brought me "mountain wine", in a plastic bottle. Like strawberries and fresh grass. Best thing I ever tasted.
Tofifee is very good, and very spread around these parts. You can sometimes buy a 5-pack for 5,50 €, which is a steal, I usually get them and then give them away, it's so delicious.
17:40 - If that's the C64C board, then it seems from the factory they only socket the VIC, 8701 & SID and nothing else. I have 2 other PAL C64C's and they are the same.
It's funny to see so many broken short boards. They are all newer than the long boards and don't burn themselves up with the 12v supply, so it's sad to see them start to fail, this might a sign that they are getting old too and starting to fail (have you checked on the field found C64 recently?)
So I bought the same magnifying goggles (they work really well, love the flip-down magnifier and built-in light!) but the adjustment at the back for head size doesn't stay put very well and the side adjustments for tilt stiffness also loosen over time. Any suggestions for how to make it work better? Where do you wear it on your head? Thanks.
Cant wait for the repairathons... very therapeutic for me, especially when its a c64. Pls dont forget to do a dance party if you ever fix a crt in the future!
You definitely need to examine SpeedDOS(Plus) more. It is litterally the best 'alternative ROM for the C64. I've used it for years! It has wedge commands similar to JiffyDOS and _requires_ that the connected 1541 and the C64 be connected over parallel (User port). SpeedDOS has proven to be very compatible indeed with most games on disk or cart.
Hi Adrian ... we have here in Germany a soft drink which is a mixture of Cola and orange lemonade called Spezi ..... but i doubt it has something to do with your Spezi System ;).
Your box of Toffeefee is also available in the USA here as ToffeeFay or something, both spellings are pronounced the same. Quite tasty but of course deadly sweet so moderation for you of course.
Hey Adrian, just FYI, the link for the Universal ZIP sockets: (clones, used on my ZIF-64 test machine) is dead. Also, where did you get that little Pry Bar with the red handle (I think)? Used to live in PDX back in the late 90's.
Nice, wasn't expecting a video today since you said you cannot keep up with mid week vids so thanks for the surprise. Also after watching you for 2ish years I only just realised your channel initials are ADB, was that intentional?
I like the quick cut to the screen when you power the system on and it gives a display. Is that a change from earlier testing / repair videos or have I just not been paying attention?
I recently started using a HDMI capture device along with OBS so yeah, in this video I was using three feeds -- two cameras and the HDMI capture. Allowed flexibility while editing.
Hi Adrian, what do You do with all the boards, when it's repaired. Thanks for many hours of good entertainment. Greetings from an old electronics repair guy, who newer could get a job in repairing. So must take the second best, I program instead.
I had a C64 with a blown fuse and the only things that didn’t work were the sound and the Datasette. Crazy how even with no fuse you could still use the thing.
I would love to discover Adrian has a store where he sells the systems he repairs. I'm not competent/knowledgeable enough to repair them myself, but I'd love to pick one up that I knew was (mostly) working.
Interesting that there are all these different ROM's for the C64. I was not aware of them until seeing this, I suppose it must have been the only way you could really upgrade the OS on these machines. Also seeing how full the dead chip box is getting, I am starting to wonder how long it will take until Adrian has to upgrade to a trunk.
When you do actual repair-a-thon, can you try #5 without anything connected to C66 to see it it acts "dead" without it? Also, why no deox-it in #6's power switch? It would have fixed it right up!
The power switch had a mechanical failure that won't allow it to stay in the on position. It's not a question of electrical conductivity. Likely a misaligned spring or some broken plastic inside is the cause.
No "Short Circuit No. 5" and climate change in a C64 @ Texas Instrument's RAM >> still too hot. SPEEDDOS PLUS is an 8-bit parallel floppy speed system. The ROM in a 1541 has also to change, and of course you need a 10 pin ribbon cable from the user port to the floppy's 6522. I think the "SPEZI SYSTEM" is a custom made SPEEDDOS PLUS system. It has the same function keys mapping.
This is all you need to know about 64 motherboards: Preferred: - 250425 (8 RAM chips) - 250466 (2 RAM chips) Avoid: - 326298 (64) - KU14194HB (64) - 250407 (64) - 250469 (64C)

Interesting that there are all these different ROM's for the C64. I was not aware of them until seeing this, I suppose it must have been the only way you could really upgrade the OS on these machines. Also seeing how full the dead chip box is getting, I am starting to wonder how long it will take until Adrian has to upgrade to a trunk.
Later in this series, we will see if NumBer FiVe really is alive.
#5 isn't missing a SID chip, it's missing a pair of them.
Missing twice!!

Adrian, the characters you have on the ZIF64 are custom made? They looks so good!
This is "VIC-20 Edition" if I am correct.
PA7 (CIA U1 Pin 9) is probably not working correctly. That's the column with the keys 1,
That German board Das Boot!
When you do actual repair-a-thon, can you try #5 without anything connected to C66 to see it it acts "dead" without it? Also, why no deox-it in #6's power switch? It would have fixed it right up!
The power switch had a mechanical failure that won't allow it to stay in the on position. It's not a question of electrical conductivity. Likely a misaligned spring or some broken plastic inside is the cause.
@@Nas_Atlas r/woooosh (I was joking, suggesting that deox-it is magical and can fix anything, even mechanical issues.)
No "Short Circuit No. 5" and climate change in a C64 @ Texas Instrument's RAM >> still too hot.
SPEEDDOS PLUS is an 8-bit parallel floppy speed system. The ROM in a 1541 has also to change, and of course you need a 10 pin ribbon cable from the user port to the floppy's 6522.
I think the "SPEZI SYSTEM" is a custom made SPEEDDOS PLUS system. It has the same function keys mapping.
I will have a side of hot RAM to go... with extra ketchup.
:D
Do you have a video on this cartridge you're using ? more details about it ?
