Nice to meet you. I'm from Japan. The first PC I owned was a SHARP-X1 (Z80-4MHz). I also own several X68000 computers (including one modified to MC68060). Ever since I was impressed with the original Athlon, I've almost exclusively used AMD machines. I'm currently tinkering with a junk RYZEN laptop that I bought at an online auction. I came here looking for information on repairs. I look forward to your continued support.Comment
