Data I/O Unisite Ebay Gamble
https://www.ebay.com/itm/188120717650 Seller
Seller had this listed as an XPI with 8Mb Ram anyone thats been in the programmign business knows this is not an XPI photos showed that it it did not have a Mini-Centronics port on the back so not an XPI, it was Equipped with a 48 pin Socket so Min 40 Pin Drivers Hope for 48 (2 Extra Cards Form Standard) Maybe 1MB Ram. With this equipment geenrally sellers will say it works if it powers up. Most don’t understand how to actually test them.
So Knowing what I know and that it was not an XPI Unit and a Gamble on the Pindriver Amount and Ram actually how much was installed. I made My offer for an ammout i would be willing to gamble. The Seller Accepted My offer.

Well, it was Kind of a Bummer it did not have 48 pin drivers only (40) or the 1MB of ram (128kb) but I knew going in it was not XPI so was a gamble if it would even work or not 🙁 but I am happy with what I received. it will be a good base for some basic refurbishment. I will only use it for the rare device older devices that requires a Unisite but i believe it will Support every device the 29B does and then some ill need to verify that.
Data I/O Unisite Boot W/ Flash Floppy V3.6 (The V3.6 IMZ Image From this Site)
Inside the Data I/O Unisite… PCB #701-2012-008 it has 10 Pin Driver Boards for a Total of 40 Pin Drivers. No Additional Memory Just the 128K base memory. 
This unisite will get a nice refresh made in 1988 and it’s pushing 40 Years old. Ill get the thing opened up further and add the photos and BOM of items replaced as I do it.
There is a Maintenance manual with schematics for this version of unisite so will be rather straight forward. Maintenance Manual later version Rev 12+. The Unisite was the last of the “Repairable” Data I/O programmers. Back in the day it company’s like Data I/O once prided them selves on serviceability. even though they charged for the manuals and repair documents service tech or owners were happy to pay a fair and reassemble amount. Knowing that they were not going to be held over a barrel for repair or service from the manufacture.
