I would think it's a programmer issue likely, they couldn't even figure out the correct fuse order for the input terms after all. I program them with a Data I/O 2900. I know other two persons using regularly the soviet clones and programming them with another Data I/O 2900 and a Hi-Lo All-07. Both of them never reported to me any failure after programming, but I've been told that some ICs fail programming like I've experienced myself. > > Had two of them in the 1551-Paddle, both of them died after some time. > One of them took a 8501 with it, unfortunately. :-( I've never seen a good 8501 in my whole life so far. I have made a replacement for it with a 6502 and 2 x ATF1502 CPLDs, this is barely larger than the 8501 itself. But I only have one C16 that was donated many years ago by a friend. > But this is just my humble experience, not a valid wide field study. > However, this took me to the idea of the redesigned paddle. > > Am 22.02.25 um 17:46 schrieb Francesco Messineo: > > On Sat, Feb 22, 2025 at 1:56 PM Mario Kienspergher <contact_at_kinzi.net> wrote: > > The soviet ones seemed very unreliably to me. > Programming was fine, but they suddenly failed after some time. > > I haven't seen one failed yet.
