Reminder to any pc with Windows 3.1 out there My 33 Mhz 486 with 200 Mbyte harddrive and 3½/5¼ floppies are not hearing the end of their service lives. Boots up as always, and never ever had a harddrive error. The CMOS battery is original, never been replaced. (rechargeable) Actually every part is original, even the power supply. Yes, it has a Turbo button. :)
