 |  Re: [eBay] Teszter
It's Commodore's own test cartridge, part number 325062-01, which was sold to repair centres. I knew something like it existed before I started developing Diag264, you even have a picture of it here on the forum but the owner never replied to me so I built my own.
During Diag264 development I found the ROM for this via one of the guys on cbm-hackers but it's rather basic and completely useless without the dongle set. What the seller does not show is the tests 'hanging' at the next step when it tries to test the I/O loopbacks. Here's a screenshot of what it'll look like a few seconds later, grabbed when running it in yape.
Here is a ROM image you can try yourself in yape or vice but it'll hang as described above.
If people are *really* interested I can disassemble the code and figure out the dongle loopbacks. They'll be something similar to what I did for Diag264.
cheers, Rob

To answer csabo's questions more explicitly.
> Was it commercially sold?
Yes, to repair centres, but unlikely it was advertised in public magazines.
> Why is the title spelled with Hungarian spelling?
Most likely because a Hungarian user burnt the ROM himself, replaced the ROm in a game cartridge and printed his own label. Most original commodore diagnostic cartridges I have come across have dot-matrix or hand written labels or none at all.
> What does it actually test?
From a quick scan through the code, RAM, ROM, I/O ports (cassette, serial, user port, uart, joy ports), timers & TED registers
> I don't think we'll know until someone gets their hands on it.
Well now you do. :-)
> Anyone going to bid?
No - if anyone wants one I'll make them one for the same price.
