Currently the unit is in pieces and at some point will need to be restored after reassembling the unit.
Do you know if it's a 32K or a (bank-switched) 64K RAMBOX? The 32K is easier to re-initialize.
Actually, it seems that I have two RAMBOX'es !!! there were with my other vintage MLDL units (ERAMCO ESMLDL1, HHP-PE, HHP-16K, etc)
The first one is a RAMBOX32 that seems to be fully functional and the second one (currently in pieces) seems to be a RAMBOX64, but I will know for sure when it's back together.
When I insert the RAMBOX32 in a 41CX-HN and I do a CAT 2, I see "-RAMBOX 32" plus some other global labels loaded in one of the banks.
Reading the user manual, I have a hard time understanding the switches functionality.
For sure, I understand group A, but the explanation of Group B and Group C is not very clear to say the least.
