1990 IBM Personal System/2 Model 30 286

The model 30 286 was on the low end of IBM's PS/2 lineup, with a 10 MHz 80286 processor, 1 megabyte of RAM (expandable to 4 MB), the standard ISA bus (not Microchannel), a 20 MB hard drive, and built-in VGA graphics. DOS runs fine, but Windows 3.11 is quite sluggish due to the slow hard drive and lack of memory. I also show how I replaced the original Dallas DS1287 clock/battery chip with a DS12887, so now it won't keep forgetting the time and date every time I turn it off. The DS1287 is long out of production, and the DS12887 is the replacement, which should work fine in most computers. You can also literally hack into the DS1287 chip, disconnect its dead internal battery, and install an external battery to get it working again -- see uxwbill's video for information and instructions: www.youtube.com
