The PC Engine was an 8-bit console that was designed with CD-ROM support in mind from the very beginning. It also used a very unique add-on system.
The PC Engine and the CD-ROM drive were completely separate devices, and you even had to purchase a separate interface unit to connect the two and play CD-ROM games. Because you needed to buy all of these components, the total cost was quite expensive at the time.
I never actually saw one in person back then, but even today, I think the build quality, design, and especially the modular add-on concept look incredibly sophisticated.
What’s even cooler is that the CD-ROM drive could also be used as an add-on with NEC computers. Pretty cool, right?
