Probably a core memory board?

Motherboard, I think.

When I asked Jussi (in July, 2016) he pointed me to http://www.ebay.com/itm/1000x-VINTAGE-RAW-FERRITE-CORES-5221...

Googling the board number returns this page http://www.oldcalculatormuseum.com/al1kck9l.html

The photo shows a shipment containing a “computer memory module”.

It’s likely assembled on a different module / daughterboard to the main board, I would assume.

The second-last pic in the article - there's a couple of 6-pin chips on the board.

Looks like Hardware peripherals

I can only that's the daughterboard; might be a TPU.

That's a TWL6030 power management chip, used for charging and powering the board from the battery. There are no side photos, but sometimes there is a trick you can do with the OMAP: put it under the RAM. It can provide pins for the RAM to be soldered on.

It looks like a test card for testing chip programming. Notice the interface pins.

Could be, yeah. I know that his kb had some tiny switches on the underside to configure some things, so you're probably right.

>Something about this...

I reckon it's probably the SIMM soldered to the breadboard.

Teal squares on right: CPUs

Teal rectangles on right (in between squares): L2

Orange mass on left: GPU

Blueish rectangle on bottom: DDR interface (?) Possibly L3, I forget if these actually have L3.

It looks like a pcengines Alix board. I am using kne as a router.

db48x | karma 6953 | avg karma 2.05 · | 2022-12-18 09:42:58

And there were a few more boards for the disk controller, and another couple for the display controller…

shermantanktop | karma 1484 | avg karma 2.46 · | 2024-02-16 15:57:12

Yeah, this looks like an Apple IIe logic board to me.

thsksbd | karma 1111 | avg karma 1.38 · | 2023-09-28 14:26:57

Thats just the board, I think

Narishma | karma 3253 | avg karma 1.67 · | 2020-01-03 10:06:29+00:00

No. It's a microcontroller board.

wmf | karma 46152 | avg karma 2.46 · | 2024-04-23 00:21:45

Maybe VRMs (although I've never seen VRMs that look like that).
