Has anyone noted this listing of what the seller is calling an "IBM 5100" on Ebay?
https://www.ebay.com/itm/IBM-5100-B1-Basic-Language-16k-Memory-Powers- on-monitor-works-but-no-text/112776476816 While it is listed as a 5100, it lacks the 5100 badging on the front center panel (to the right of the power switch). In addition, the indicia on the bottom (https://i.ebayimg.com/images/g/9VYAAOSwaC9aapB-/s-l1600.jpg) indicates both models 5100 and 5110, and the KVA is listed at 0.4 whereas 5100s are 0.336. Compare the typical indicia on the bottom: https://tinyurl.com/ybmvms7u. The serial number is in the 5100 format of 10-1XXXX, but this unit has the highest serial number I have seen on a 5100 (10-15687). I am guessing that this is some sort of transitional version or perhaps a 5110 "prototype". Any thoughts? -W
