Oh, I take it you mean in a separate chassis with it's own power supply then.
(I thought you were referring to the interface boards in the CPU chassis).?
Per the OP's machine, the early HP21xx machines were based on CT?L, for which the
main supply is +4.5V.
DTL and TTL chips in these machines ran off that 4.5 supply.
The DTL I referred to in my posting are in a third-party (IOMEC) disk
controller, not the HP 2114 CPU.
