Hi there,
i bought some breadboards and wasn’t really concentrated.
They have their advantages, though i decided to use them, too.
I couldn’t find them here. Maybe someone wants to help ?
Here’s a photo.
Many thanks in advance !So long

Not enough here to do anything with. There is no indication how this is different than the standard breadboard and no web site with data on what you want. Added to that is modifying breadboards is a lot of work, and it doesn’t look like this one is very different from a standard one.

Hi Peter,
all +/-lines are cutted in the middle.

When I looked closer it is in fact quite different than the standard breadboard (although the image is so poor it is really impossible to tell!) First from the image you provided the pin numbering is odd (starts at 0 rather than 1, 0 is not the left most row and goes to 60 which would imply 62 pins. A standard breadboard has 63 pins.
and starts at pin 1 on the right side
Here I overlaid you jpeg on the standard breadboard svg and blanked out the board background to allow the breadboard pins to overlay the jpeg.
The results are confusing. It is impossible to figure out what is going on without better imagery. A web site with decent images of the breadboard you have (preferably flat and square) may make this doable but at present it appears to be too much work to be worthwhile as it doesn’t appear to be a standard breadboard in any sense.

Hi Peter,
yes, of cause. Ii’s too much confusious stuff. For me, it would be nice, if you could take a standard breakboard and cut the +/-lines it would be great. 62 or 63 doen’t matter to me, but i will look after some photos from factory to solve the how-many-holes-question…

Hi Peter,
this is a MB-102 breadboard with 830 contacts.
More Pictures are appended. The difference between the holes is not 2,54mm. It seems to be 2,50mm. I will take them back. No need to build a part.

There are a few out there. A google search for “4 bus breadboard” turns up a bunch (mostly in multi board lots.) This one is the only individual one I saw anywhere though although I didn’t search that hard because I have no need of one.
If you come up with one that is available I’ll consider making a part for it. Easiest is one that matches breadboard2 in pins (but not power rails.)

You got lucky. I found one of these on digikey with a mechanical drawing (and the same odd numbering as all the rest I could find.) With that I made a custom part that should do for most any of these.
edit:
Typo on one connector (the bottom 1 should be a 0.) Part replaced with a corrected one.

the url in the part points to where you can get it from Digikey, but it is available on Ebay and the other common sites as well in various configurations (usually in 3 board sets on a base plate) but cheaper than Digikey.

hello peter,
When I looked closely I noticed that your board is not exactly the same. But this is just for your information that not everything worked during production:
look at the prints ‘55’ and ‘60’ on both sides. On one the distance between the numbers is 4 holes and on the other it is 5.
Funny !
And yours is better!

There is an error in the part (or more correctly was an error in the part as it has been corrected) but it isn’t the one you pointed out. The one on the bottom right should be a 0. Otherwise it exactly matches the board available on digikey (and should match all the rest that I have seen.)
edit:
The 6 holes between 0 and5 is correct as pin 1 would be 5 holes from 5, the bottom one is indeed incorrect as there are 6 pins between 55 and 60 (I assume the first one of these had these errors and all the rest copied them!)
