I took out my A1200 today to remove the battery from its turbocard. Even though it is a sealed lithium battery, which usually don't leak, it IS over 20 years old, so, it was time to go. I have a replacement on hand, but, decided not to install it.
Specs: PAL A1200, in a NOS case and NOS keyboard I bought several years ago. At that time, I recapped the motherboard, removed the modulator, installed a CF card as the HDD, and an Indivision. A Gotek drive was installed into the machine via a 3D printed bracket and, I printed out a friction-fit OLED display to show me what image I am using.
It has a Blizzard 1260 with 128 MB of RAM in it, which started out as a 1240 -- I desoldered the 040 and installed a Rev 6 060 (as well as the required voltage change modifications (5v changed to 3.3 V) and replaced the angled SIMM slot with a flush mount one so I can close the trap door. I also changed the crystal oscillator to overclock the REV6. It runs at 66 MHz instead of the stock 50 MHz, and it flies. At 66 MHz, there's barely any discernible heat.
I am running WB 3.1 in DBLPAL mode, which looks gorgeous on my Dell U2410.
