In addition to equipment from Mercer Island, the museum's 5XB also has frames gathered from other offices as well, including:

* Completing marker 1 (CM1), a U & Y type marker that is an older design than the wirespring CM0

* [[Completing marker]] 1 (CM1), a U & Y type marker that is an older design than the wirespring CM0

* A "minibar" auxiliary line link frame with mini crossbar switches

* An older style number group from the RE-2 office

* An older style [[number group]] from the RE-2 office

* LAMA frames from an unknown office.

* [[Local Automatic Message Accounting|LAMA]] frames from an unknown office.

* Revertive pulse outgoing senders (OS's) and incoming registers (IR's) from New York.

* [[Revertive pulse]] [[Outgoing sender|outgoing senders]] (OS's) and [[Incoming register|incoming registers]] (IR's) from New York.

Since its basic initial installation, the 5XB has been expanded and augmented by museum volunteers in order to present a more complete view of the capabilities of the machine. In the 1990s, Steph Kerman donated the RP OS's and IR's mentioned above, allowing the switch to once again communicate with the museum's [[CMS:Panel Switch|panel office]]. The OS's feature a novel modernized counting chain circuit on a ~~PCB~~, manufactured by CMC Corporation to replace the 208 type relays and RP stepper that would have previously been used.

In the 1990s, Steph Kerman donated the RP OS's and IR's mentioned above, allowing the switch to once again communicate with the museum's [[CMS:Panel Switch|panel office]]. The OS's feature a novel modernized counting chain circuit on a printed circuit board, manufactured by CMC Corporation to replace the 208 type relays and RP stepper that would have previously been used.

In the late 2010's volunteer æstrid Smith wired up the Pretranslator (PRT) to allow the machine to translate on a varying number of dialed digits. (Before this was returned to service, a museum caller could not dial common three digit codes, like 411, 511, etc. They ~~would have~~ to dial a full 7 digits, like 511-1111 in order to complete their call). At the same time, æstrid and Sarah Autumn configured the machine to place calls to the [[C*NET|C*NET collector network]] via [[CMS:Kercheep|kercheep]] using 1+7D dialing.

In 2021, volunteer Sarah Autumn fully repaired the trouble recorder, which had not been working for several years. This was a substantial addition to the switch, as the trouble recorder was one of the primary diagnostic tools used by technicians.

In 2022, Sarah brought up the ANI frames, which allow the 5XB to outpulse the calling number to the [[CMS:Kercheep|kercheep]] tandem. For example, dialing KE7-1111 from the 5XB will cause kercheep to read back the phone number of the calling telephone which is sent out from the 5XB during the call setup process.

In 2022-2023, Sarah acquired further equipment from Steph Kerman and Steve Flocke which allowed the switch to complete coin calls, both on an Intraoffice (IAO) and inter-office basis. Steve Flocke's main contribution was the Coin Supervisory Link, which he designed and built for the museum.

In 2024 Sarah wired up the Automatic Monitor Register Sender Test (AMRST) equipment in the Master Test Center (MTC). This equipment allows the 5XB to monitor and test its own senders and registers for faults while in operation.
