hi @ All,

i have implemented the 16-Channel-System on my ES32-Simulator for the Pidp1, not only the Software, the Simualtor has now 16 real Channels and can handle these with the origin Opcodes.
i created a SBS-Indicator-Panel in Kicad, but it's not finished at all.

i try to include these Feature (includes the Hardware-Pins and the replica of the sbs-indicator-panel with all the Leds) later to the simh-Software.

to test the functions from code i wrote a small programm wich reacts to channel 0, but it seems that macro1 cannot handle the asc Opcode to connect the channel 0 to my programm. 

i will try Bill's AM1 to solve this problem, but i tought that macro1 can handle the sequence-break-system :(

have anyone a idea how i can assemble the mac-file with the asc-opcode in macro1 ?
And i have no idea, that the program is correct :)

Just use the numeric equivalent, 72nnnn51 where nnnn is the channel number.
And, that reminds me, I need to add some of those opcodes as permanent symbols in AM1, not just as defines.

i have i working program to test my sbs ...

the program counts in a never ending loop,
when a break accoures at channel 0, its calculates another variable and send the result to iot12
then it goes back to the point of return .

i'am happy for now :)

i have added a chart with the 16 memory locations for all 16 channels, if anyone needs this :)

Hi,

I've never used MACRO but for asc Channel 0 will it accept:-
iot 0051
Regards,
Garry
