Unlike my floppy drive box, only a single goat has pissed on my PCjr box

The most important port on the IBM PCjr is the LP port, which is for the light pen.
From left to right, we have the joystick ports, J J, after which JJ Abrams was named.
Nobody knows what the L port is for. If you hook a speaker to it, sometimes you hear voices in forgotten languages.
The K port is for the keyboard.
The T port is where you connect a better computer, your Tandy 1000
A strange property of the gaping M port is that no light can escape it. This is normal.
The M port was for a modem but this was a stupid move on Ibm's part because the Internet hadn't been invented yet.

@gloriouscow JJ's namesake is not hard to find in good condition, and often still BNIB! #retrocomputing

The D port is where you can connect a display. You can use a special cable to attach a normal CGA monitor. You can purchase such a cable for $20 from someone who got it from Computer Reset for $3

@gloriouscow I wish I knew why I was spending so much time and money trying to save my flood victim PCjr

@gloriouscow that's the "manicure" slot. You can drop fingernail clippings in there, just like you would put razors in that slot in your medicine cabinet.

The most famous orifices on the PCjr though have to be the cartridge slots. They're a pair of dust magnets located directly under the floppy drive.
Inserting a cartridge into one of these will immediately reboot the system without confirmation. Be sure to do that while Daddy is working on a spreadsheet.

@gloriouscow Thank you for the memories

The first thing a new PCjr owner is going to want to do is remove the frungus modulator. You don't need this, it was only added for compliance with French law

Oh wait my bad we do need that, put that back.

I may be way overthinking things here. But reading between the lines I almost suspect you may not be 100% satisfied with the design decisions and manufacturing execution of this piece of hardware. -

The peanut is the best thing people with MBAs ever forced engineers to make

@gloriouscow This thread on the Tandy 900 is amazing!

@gloriouscow i don't believe i've ever seen a PCjr cartridge in my life, not even online. i think i searched to see what they look like and got no results -

@gloriouscow nah, the first thing a PCjr owner is going to end up doing is ordering a replacement keyboard (assuming they got the chiclet style one)
and the second thing they're going to do is order a tandy 1000 -
Here are the two IR Leds and the jack for connecting a keyboard cable. Let us look closer
@gloriouscow ah, that's right, IBM really did think they could pull off a wireless keyboard in the 80's -
Look right in here. Right up in this connector that can make your terrible wireless keyboard a terrible wired keyboard
@gloriouscow or you could plug a phone handset into there to presumably talk to your keyboard! -

@timixretroplays @gloriouscow we really did think as a species that this was an acceptable joystick design, huh -
@gloriouscow I tried to make my pcjr keyboard wired, using the cable. But it turns out the protocol is deeply stupid so I never got it working
@foone @gloriouscow i have no idea why IBM thought using what looks like an RJ11 port but probably isn't actually wired like one was a good idea for connecting keyboards. my IBM 3151 terminal is similar, but it uses an RJ45 cable instead. thanks to it, you can buy an IBM model m keyboard with a fucking ethernet cable coming out of it -
@timixretroplays @gloriouscow we really did think as a species that this was an acceptable joystick design, huh
@mjdxp @gloriouscow honestly it's more comfortable and ergonomic than many significantly more modern controllers
