Thank you for the information.

I have not found a proper comparable to establish a valuation on this for you.

I will opt-out and your question will open again to all the experts. If someone knows the answer they will post a response to you here. You do not need to re-list your question and this does not cost you extra. There is not a guarantee that you will receive a response.

I will not be able to respond back after opting-out

I do hope you find the information that you seek.

Hello, my name is***** am a certified appraiser and would be happy to help you. You have a very interesting item and I would be happy to research this and see what information I can gather for you. Do you know about when this was made? What type of computer was this built to use on? An apple or an IBM type of computer? Certain prototypes are formed for certain type of computers. I look forward to helping you and will begin on the historical aspect of these types of units. Thank you

Hi. My name is ***** ***** I'll be glad to help.


I think I recognize the main board on it. Is that what you're trying to identify or are you trying to determine what that board was used to make?.


Do you have more photos of it?
