Notes:

In some cases newer (or bigger) CPUs may be used in place of older ones, i.e., use of a 2100 or 2116 as an I/O Processor in place of a 2114.
21MX can be M-series or E-series.
2000/Access processors must either both be 2100, or both be 21MX.
Fixed head discs are:
- 2770A
- 2771A
- 2766A (2000C, High Speed 2000C, and 2000F only)
Fixed head drums are:
- 2773A
- 2774A
- 2775A
Some additional disc devices are supported in some versions of the software.
The "old" terminal multiplexor is the 12584A.
The "new" terminal multiplexor is the 12920A
High Speed 2000C is also known as 2000C' (prime), and uses the same IOP code as 2000F
2000/Access can use 7900, 7905, 7920, or 2883 disks, but can't combine 7900 and 2883 on same system.
2000/Access IOP memory required depends on features and device support configured.
