TI-99/4A Related -- Image challenge thread

[Omega-TI]

The rules are simple:

 

1) The winner gets to pick the next photo.

2) The first one to guess correctly wins that round.

 

I'll start the ball rolling with this...

 

[GDMike]

Rs232?

[+FarmerPotato]

Supersketch

 

The ADC and connector are the ringers.

I tried to go change my answer, but was kicked out my internet...but maybe I'll get the next

Dang, I thought that would last a bit longer!  Well, you win that round, your up! 

[+Ksarul]

One note on that one, the PPI on the board, with Irving, TX under it would have been the most obvious clue. . .I do have to laugh at the fact that they had to redrill the central hole in the cartridge board though. They must not have had their calipers set right when they laid the board out.

[+FarmerPotato]

Must guess what it's from and its function!

 

[Stuart]

Well that would be the console keyboard connector.

You are correct Sir! Your turn to post an image.

[Stuart]

OK, lets step it up a bit - where would you find this?

 

 

You're more likely to see it this way round:

 

 

Hint: it's an item manufactured by TI.

The serial connector on the RS-232 card!

[Stuart]

Correct!

[AwkwardPotato]

Okay, what is this a picture of?

 

[Stuart]

The PEB cable 'foot' that plugs into the console?

 

(With some questionable soldering quality bottom right ...)

[AwkwardPotato]

Correct, and good call on the soldering quality.  That was a quick fix a couple years back when I was touching up the PCB (rubber piece underneath it started rotting), should probably hit a lot of those joints again with some flux.

[mizapf]

Not my turn, I know, but what about this one:

[JB]

It is a circuit board and some chips!

[AwkwardPotato]

The TI 32K card?

[mizapf]

Correct! How did you know?

[+Ksarul]

I recognized the capacitors--TI used them everywhere on their memory boards--and the 32K was the most likely one, based on the part number of the visible memory chip.

I couldn't think of any other TI hardware with 4116s on it (besides the motherboard, but it doesn't look like what's in the picture). Also the black silkscreen on green soldermask, the only place I can remember seeing that is on the PEB cards.

 

I'll let somebody else go after me since I posted a picture only a couple days ago
