IBM PS/2 vs PC

The IBM PS/2 line was a fairly radical departure from the older IBM PC line. This was deliberate, as IBM wanted to disrupt the clone industry, which it saw as a threat to its business. Here’s a look back at the IBM PS/2 vs PC, the line it replaced.

IBM succeeded with the PC because it created an ecosystem, not just a PC. IBM’s misstep was creating an open architecture and then trying to close it back up after the fact with the PS/2. In IBM’s defense, it’s not clear whether they knew this at the time. If nothing else, in the case of the IBM PS/2 vs PC, IBM created a classic case study of open architecture vs closed.

Proper wiring for the LW transformer is a bit of a safety issue. It’s not just about preventing voltage drop to keep your train running smoothly. A smooth running train is nice, but safety is a must.
