Cisco VCO4K quick overview, looking for a CPU card

Описание: This is a rough "quick" overview video on a Cisco VCO4K telephone switch I've recently acquired. These were originally made by Summa Four before they were bought out by Cisco, and are predated by the SDS-500 and SDS-1000 switches. It is basically a digital switching platform that can handle all the telephony functions for call processing on TDM and analog circuits (including tone generation/detection and signalling), but completely controlled by your own custom software on an external host computer. They were widely used for calling card processing but can of course be used for pretty much whatever you can come up with and write into your host application. Other "real world" uses included directory/operator services, assisted dialing, call queuing/custom routing, and based on comparing some audio prompts it seems one of these is in use at a friend's nearby CO for an internal line and trunk testing application. The one I have here is mostly complete, just missing the CPU cards (of course) so until I can find them, I can't exactly do anything with it. It does have the SCSI hard disks installed on the rear I/O cards, one of which was functional and I was able to image, all the files are present for a basic system including a bunch of audio prompts that I'll be posting in another video shortly. The overall plan once I get the switch itself booting is to write host software to make it into a little class 4/5 central office. It won't be perfect as it has no native support for Bellcore caller ID generation, the DTG leaves out the stutter dialtone and call-waiting beep for some reason, and unless I get a SLIC card for on-switch FXS ports it won't be able to recognize a hookflash or rotary dialing over ports on a channel bank. It should be able to more closely emulate an actual central office than anything else I have however, it also will be able to more fully support MF signalling so I could have "real" FGB/FGD trunks. Once I am able to get it working and have a basic telephone switch application written, I'm thinking I should also be able to make a custom board that does the extra tone generation and FSK encoding for proper Bellcore caller ID and call waiting, and provide it to a T1 port that could be routed to phones, but of course I need to do a bunch of testing to make sure that it even behaves as I think based on the manuals.

Things I forgot to mention:
-"VCO" stands for "Virtual Central Office"
-The administration console isn't actually a command line, but is a "graphical" field-based interface similar to the Adtran Atlas
-CPU redundancy is implemented but isn't required for operation
-The "4K" is referring to it's maximum capacity of a little over 4000 timeslots assuming all the card slots are full
-The ICC cards are not used with the rear FXS, FXO, E&M, or drop and insert interfaces, they have their own specific versions

TL;DW:
-I got this VCO4K here's what it looks like they're really cool!!
-I still need a CPU card for it to be functional
-If you know anything about these or have ever worked with them please leave a comment
-Approximately 36% incoherently getting off topic and losing track of what I've already covered...
