Bull****. The technology in a PC today is quite different than that of
a PC made in 1988. Nothing in a PC from 1988 would even "plug into" a
PC bought today, except maybe the keyboard and mouse. And the PC today
is literally orders of magnitude faster.


The original mice I first saw plugged into a special jack on a card
that plugged into the PC. I had mine on a combo card with video. The
technology to allow a mouse to run on the low power in a serial
connection came later. And serial connectors vanished around Y2K. I
don't know how the data signals in the PS2 mouse connectors compared
to the 9 pin serial connectors.

Keyboards plugged into a large DIN connection. This was gradually
replaced by the smaller PS2 connection, then again with USB
connections.

I don't know if any desktop computers still provide PS2 connectors. I
don't think so.

I'm still using my 1994 laser printer. It plugs into a
centronics-parallel to USB adapter. I guess similar adapters are
available for serial ports and PS2 connectors.

Hmmm, come to think of it, the Centronics port was designed for the
1988 TRS-80 computer. A printer from that era would probably plug
through my adapter into any modern Windows computer. And at least the
MX-80 and its clones are probably still driver-supported.


Not quite.

The Centronics connector, also known as IEEE 1284, was designed by
Centronics in the 1970's as a general parallel port interface.
