After over a year of market stagnation, I have found a TI-82 with ROM 1.0. It is expected to arrive here before 28 February 2017.
Serial number 0500730 (!); date code I-0593.
Image Image Image

ROM 1.0 was speculated to exist as a United-TI member claimed to have a TI-82 with such a firmware, but efforts to contact the user failed. After a year and a half of searching, a calculator confirmed to have this ROM version has been found. At this point, only 3* remains undumped.

----

I also blindly purchased a TI-82, serial 0510400 I-0593. We'll see what it has when it arrives (hopefully 3* :D ). Notably, the serial number is lower than the TI-82's with ROM 3..

Great, congratulations ! :bj:

Unlike the 1.0 TI-81, I hope the 1.0 TI-82 can be dumped the usual way this time. ;)

Fortunately, the only thing we know about 1.0 is that the assembly loading exploit still works. It exhibits the same behavior as 3. when executing a shell: it loads machine code with incorrect addresses, leading to a RAM clear.

Well, I just blindly purchased a bundle of 4 graphing calcs (2x TI-82, 1x TI-83, 1x TI-83 Plus) + a TI-BAII, all for around 50euro :P (thank you for the tip, btw)

We'll see if there's anything interesting, otherwise we can hope there is going to be some resell value in this...

I think it's also worth noting that the two TI-82s purchased by Adriweb are potentially interesting; we never got to see any serial numbers but the physical characteristics are consistent with other prototypes.

@CVSoft You got the TI-82 1.0 ? ;)
Could you dump the ROM the usual way ? :)

It is already done. And some photos are in its dedicated album.

BTW from EFNet #ti:
04:15:48 <notipabot> TI-82 ROM 1.0 has been dumped.
04:16:29 <notipabot> it behaves exactly like 4* as far as bugs go
04:17:09 <notipabot> which means, interestingly, that ROM 3. introduced a bug
