It was specific for the MC-II.

FYI, if you open up an EPROM module you will find that it contains an standard EPROM.
Hitachi HC27C101AG-20 (1Mbits or 128Kx8bits, 200ns) [datasheet]
Any standard EPROM programmer can program them.

Emmanuel a French member here (3e0_rtn) has done exactly that.
He has successfully reprogram the module and has posted his pictures on the HP-41 French users group site here
You must be logged in to see the pictures, if you cannot, I am sure if you contact him he can send you the pictures.
