>It's not complicated to come up the first time when you have the Original Compupro Masters for 3.1 or 3.1DM. 8-bit boot Loader is sysgened on Disk #1 and 16-bit boot is Loader sysgened on Disk #2.
I read that in the docs but my copies weren't that way.
>If you haven't noticed already, CDOS comes up noticeably much faster with the 286, than it does with any of the dual -processor boards.
Yes I did notice that. Boots in a flash !!
>Have you set your SW! program yet? Do you have a SPU-Z 8mhz Z-80H slave processor board, or are you running the EM8080 8-bit emulator since you don't have the Dual Processor board in the system anymore?
Hmmm - haven't thought about that yet. I have two CPU-Z boards, one is 458B from 1985 and the other is marked 160K from 1981. Would one of these co-exist with the CPU 286 board?
No, both the 160K and the 458B are both Master Processor Boards. You cannot install either of those Processor boards in the system at the same time as the 80286 board is installed. Compupro manufactured both Master Processor Boards, and Slave Processor Boards. Masters cannot be used as Slaves, and Slaves cannot be used as Masters. Control of the bus is switched between Masters and Slave Processor Boards according to IEEE-696 Specifications.
The 160K is a 1st Generation Z-80A/Z-80B board capable of running 2-6mhz. It is Imsai Front Panel Compatible. The 160K is the most common and most successful of the Compupro Z-80 processor boards. The 458B is a IEEE-696 2nd Generation Z-80H Processor board with a 8mhz Z-80H onboard, not Imsai Front Panel Compatible. A very fast board, it may require some speed modifications to the original Compupro support boards for reliable operation. Also requires wait states with all but the fastest Compupro memory boards.
Compupro manufactured two Slave Processor Boards. The SPU-Z was a 8-bit 8mhz Z-80H with dual onboard serial ports (early versions of the SPU-Z were single-user and 64K only, you could only run one in a system) and either 64K or 256K of dram (single user or four-user slave processor), and the SP-186 16-bit 10mhz 80186 with dual onboard serial ports and 512K of dram (two-user slave processor). Users on Slave processors could have Console I/O on the onboard serial port (unloading the main processor), or use a System I/O port such as available on a Interfacer-3 or Interfacer-4, or SPIO.
CDOS was set up to run up to eight of each of these slave processor boards, addressed as a 64K window (a single 64K block for the 8-bit slaves and a single 64K block for the 16-bit slaves) at the top of the 1st 1Mb block of memory.
I've been running three Ram-22 256K static memory boards, and one Ram-23/128K static memory board for a total of 896K of main memory to make the necessary 128K hole for the slave processor boards, since the Early-1990s. I'm getting ready to switch back to a single Ram-24A 1Mb static ram board to save three S-100 slots, some power, and get some heat out of the mainframe ((1) memory board with (1) 5V TO-220 regulator, to replace (4) memory boards with (11) 5V TO-220 regulators).
CDOS includes three switch programs for 8-bit slaves SW!XXXXXX (8085, EM8080, SPUZ), and the 16-bit switch for SP-186 slave processor boards.
