The manual was hard to find, I had to purchase a Racal Dana collection CD from eBay to get it, but at least I now have a load of manuals !

I’m not home at the moment otherwise I would add others now, I did post it on my Patreon when I did the pre release video post.

Some small hardware differences with yours .

If the keyapd goes bad an ALPS brand SKEGACA010 fits perfect, no lead bending, no stem adjustments, no nothing, just solder in.  However, the finished button height may be 1mm or so higher (barely noticeable, or not noticeable if you replace all the switches).  The caps fit only slightly snug, maybe even "good enough", but who wants to lose one ?? So add a drop of rubber cement & you will be in the winners circle.  This switch has recently been discontinued in 2021...so buy them while you can.   I bought 100 for $23 (& then another 100 more) from onlinecomponents.com (they are supposed to get more of them in stock). Arrow's pricing is next best.   https://www.mouser.com/datasheet/2/15/SKEG-1371040.pdf   Mouser prices is $$$.  Apparently the style is called a "joint stem" type, which may help in more searches.  https://www.eevblog.com/forum/repair/racal-repair-idea-quick!/

Hello,

Maybe someone can help me with Racal Dana 2101 counter GPIB board EPROM dump?
I have fitted GPIB board from model 1998, but does not work, different firmware.

Many Thanks
