I thought the 8031 had an option to boot externally if you tied a leg low... On vacation and too lazy to hunt for data sheets to view on my phone, as I will be wandering around Oxford (UK) for the next two days. Then London on Sat and back home Sunday. John :-#)#

Will copy the binary code there too, makes more sense as it is not actually part of the adapter project.
In case it's not obvious (given the Subject line) the above OAK keyboard was used on the earlier 9100A. I don't have an A keyboard but I believe you can use an A keyboard on an FT and vica-versa.
I de-soldered and dumped the ROM of one of my 9100FT keyboards (they are all the same).
Attached are some pics of the 9100FT keyboard and a Keytronic KB-101 I got for $20 off eBay (it had been mentioned previously as being a possible conversion candidate - http://seven.pairlist.net/pipermail/techtoolslist/2017q4/002920.html)
This is the standard KB-101, not the Plus version (which has a different LED layout). The cable feeds in from the opposite side than the Fluke otherwise it's very similar, ignoring of course the keycap labeling.
The KB-101 is unfortunately a different board version. There is a socket for an EPROM which is unpopulated. The microcontroller has slightly different markings (20417-65/8031) than the Fluke (20417-36/8031). If I connect the KB-101 to a PC it works which is interesting as normally the 8031 has no internal ROM.
The KB-101 cable is pinned out differently and there are more DIP switches on the KB-101. Populated with the Fluke data and using the Fluke cable, unfortunately, it's not recognized by the 9100FT.
I only had 20 mins to look at it. Hopefully I'll have more time this weekend. It's possible one of the additional DIP switches selects the external ROM. Anyways, here is a link to some pics and the ROM data which I know Andrew Finn was looking for -- https://drive.google.com/open?id=1eow5jZ0RXSx4OVqG05EAQvBJIj_DSySA
