In March 1982, Hewlett-Packard announced the HP 3000 Series 64, an ECL implementation with a WCS.[1]
September 1985 brought the announcement of the Series 37, a low-cost gate array implementation which eschewed the usual separate control processor for booting and
used an initial bootstrap from the 32-bit wide ROMs to load the 64-bit wide boot microcode into the WCS.[2]
It's unlikely that the MPE based HP 3000 Series 64 microcode development system (MDS) software has survived, but an HP internal 543 page assembly listing exists.[3] The Series 37 Design Capture and Documentation (DCDF) tool for capturing designs for simulation in FTL (IBM 370) on an Amdahl V6 is also unlikely to have survived. Unlike the Series 64 listing, only a single line example is shown in the HP Journal for the Series 37 microcode.
The WCS data needs to be recorded on the backup tapes. The System Tables manual describes the Sysdump (Backup) format describes the tape format and the WCS data can be included as part of the first file on the tape, but I haven't seen that in the tape images I've seen. The second file is a concatenation of a list of essential system files and does include the WCS files. The files seem to be dumped as they would be in the Store part of the backup, including the 256 byte (MPE sector) file label. So SYSWCS64.PUB.SYS for Series 64, 68 and 70; SYSWCS37.PUB.SYS for the Series 37 and direct successors. WCSLE1 and WCSLE2 for the Series 37 successors. The files are single extent with 128W FB (256 bytes) records, and a zero file code. The first 256 byte record contains the version and probably a checksum. Assuming the data is 64-bit horizontal microcode the maximum is 10240 entries.

Between the first dated and last dated versions, excluding the first 256 bytes containing the version and checksums SYSWCS37 47 64-bit wds, WCSLE1 44, WCSLE2 49. Between the first and last WCSLE1 and WCSLE2 versions 186, less than the 600 between the first 2 SYSWCS64 version. Assuming that 0xa5a5a5a5a5a5a5a5 is a NOP, the first SYSWCS37 has 8867 64-bit words and WCSLE1, 9019. When including offsets the SYSWCS37 and WCSLE1 differ by 6330, but excluding offsets only by 462. This suggests that SYSWCS37 and WCSLE1 & WCSLE2 share the same 64-bit microcode, but perhaps the code was restructured over and above any necessary changes for the new machines between SYSWCS37 and WCSLE1.
