The links to CP/M-86 sources are interesting. Thanks to previous participants in the discussion.
I have various Intel iSBC-86 boards and will try to boot the disk mentioned below.
Following the links on robdaemon’s post #3, I located a Teledisk image of a DRI boot disk (8 inch) containing CP/M-86 v1.0 for the iSBC-86/12. It’s disk 23 in the collection listed under the heading MP/M-86. There a jpg of the disk and BIOS code files.
It should have been obvious that DRI would have a version of CP/M-86 for Intel’s systems. An Intel document, Article Reprint 286 (AR-286, June 1983) has the title: Software That Resides in Silicon. It describes the Intel 80130 and 80150 40-pin ICs. The 80130 contains “The iRMX-86 Kernel in Silicon”. Similarly, the 80150 contains “CP/M-86 in Silicon”.
The text continues: “CP/M-86 is a single-user, single-tasking system written in position-dependent code. The 80150 contains the entire CP/M-86 operating system; for many configurations, it requires no off-chip code. Intel’s goal was to use the configuration-dependent CCP and BDOS elements as a base, and add to them a BIOS that supported a variety of peripheral components but was still configuration independent”.
The article provides further discussion of the implementation. What it doesn’t mention is which Intel boards were designed with the 80150 in mind.
Intel publication 230786-001 Software Handbook 1984 contains a Datasheet detailing the 80150 and 80150-2 with iAPX 86/50, 88/50, 186/50 and 188/50 processors. The Datasheet is publication 210705-002 dated September 1982.
“CP/M-86 is a single-user operating system designed for computers based on the Intel iAPX 86, 88, 186 and 188 microprocessors. The system allows full utilization of the one megabyte of memory. The 80150 stores CP/M-86 in its 16K bytes of on-chip memory. The 80150 will run third-party applications software written to run under standard Digital Research CP/M-86”.
However, it appears that the ‘Software in Silicon’ experiment was short-lived.
Further discussion (March 2017) of the 80130 and 80150 is at
“A similar part was made by Intel called the 80150-2. The 80150 was merely a 80130-2 with different firmware. In this case the entire CP/M-86 Operating System was squeezed into the 16K ROM of the chip. This proved to be even less popular, likely in large part to CP/M being a rather expensive and unpopular OS at the time. To date, I have never actually seen a D80150-2 part”.

“Intel stopped making the 80130 before 1988 however, leaving them in the position of needing a chip that they designed, but no longer made. It wasn’t worth making runs of them in a fab, as this was capacity they needed for other, profitable chips, and likely the process they used to make it originally was a relic of the past. So Intel did what InnovASIC does today…. They recreated the 80130 in a gate-array, in this case a uPD65040 series from NEC”.
