Windows 7: Can you ID this circuit board?

Can you ID this circuit board?

I found this circuit board in our dumpster and I wonder if anyone know what it is. I've Googled some of the number without much luck other than hints at it being from aviation. With the REV being handwritten it must be a highly specialized piece.

The chip here has a window through a small chip with several tiny wires is seen. Maybe it is a EEPROM, Electronically Erasable Programmable Read Only Memory. They were truly flashed to erase them, with a beam of, I think, UV light.

It will be interesting to see what our Windows 7 forum experts come up with.

Who does their dumping in that bin? Could that be a remoter control card.

Correct on the chip with the window, we used to use them at Thomson in Indy. They could be erased and reprogrammed with the latest version of the micro software before the software was written to a read only micro. Spent many happy hours wiping and programming chips.
The Toshiba chip TMP is a programmable interval timer micro used in consumer electronics. The date of design is 1982. The M80C85 OKI is a master Micro and the Hyundi is S RAM. The OKI 3MHZ MICROPROCESSOR. The SN 74LS244N chips are switching buffer chips giving outputs depending on the inputs on pins. BP is a Samsung part number. This looks like a controller board for a washer, dryer or a dish washer IMHO.

I thoroughly washed and disinfected this thing when I brought it in.

Thanks for the replies so far. This would have been a fairly fancy board for a washer, dryer or a dish washer but who knows? It obviously went into a big slot and locked in, hence the white release levers in the upper corners.


I suspected the Hyundai chip were memory of some type since there is RAM bearing that name still out there, usually OEM types.

The eprom and CMOS chips are only 8 bit. The Hyundai chip is 8K x 8-bit CMOS SRAM, 85ns. It also has some timer chips. Perhaps a printer or other office machine. It's not PC related. A Guy

Is there anything that suggests it can generate frequencies, say for a radio of some sort, or radar/sonar?

The red square is a 10 position DIP switch, from 0-9.

An Eprom, some logic, and a bunch of timer IC's mostly. I doubt it does anything with much complexity. A Guy
