Diagnostics were developed on them, too. Do you mean PDP-10 I/O bus (TD10) connected DECtapes? Of _course_ they had them on their front ends! Anything with a serial number below 2100 (or so) was manufactured as a 1090 (or 1080), in bright blue "high boy" (rack height) cabinets, with "external" core memory that had multiple ports, and could be used for SMP. The higher range were either 2040/2050/2060's (orange) or 1091's (a paler blue), in "corporate" (VAX height) cabinets, with "internal" semiconductor (MOS DRAM) memory. 2065's (and 1095) were manufactured in the FCC RFI safe boxes (designed for Jupiter) were any of the FCC cabinets blue??

The Jupiter microcode people had a system "IO - One of Jupiters Moons" -- I suppose that could have been #2530... On the topic of low serial number KL's, here are two other famous systems: 1038 ITS Macsyma Consort MIT, Cambridge KL10 1075 SAIL SAIL Stanford, CA KL10
