That page shows a picture of the H214 core memory board that you mentioned
and I was thinking of. It is at: http://www.compsy.de/moduls/gifs/H214.jpg.
I remember the handle color as lighter than the G cards and that picture
does show the color that I remember but the colors on that site are often
off. You'd probably remember if the H card had a different color than the
presumably adjacent G cards of the set however.

I've seen A cards, the handles are yellower than orange. That site doesn't
show the color well. The "yellower than orange" color would match the
"A=amber" definition I heard.

Cruise around that site and they have a few pictures of cards with gray
handles, which apparently didn't have any numbers.
