Corcomp RS232 problem

[Astharot]

Hello every one Corcomp rs232 board is strange..

i discovered that no work if i have corcomp FDC card.
This is PEB configuration:
PE cable Slot 1
TI-RAM 32K Slot 2
Horizon 2000 Slot 3
CC rs232 Slot 7
CC FDC Slot 8
Computer go in crash at power on.
Leave CC FDC at insert TI FDC and computer is working and if i write command OLD RS232 the CC rs232 card light on.. at now seem that CC rs232 and cc fdc have equal address / irq or that go in conflict.. every one have jumper info for cc rs232?? I think is release one.

Had a strange upgrade maybe for use with geneve computer??
Thanks at all

Could be the Horizon is infact crashing the system on power-up with the corcomp FDC, not the RS232.

Forget.. for test i first leave all board.. only PEbox cable and rs232 and working.. after i insert cc fdc and TI99 go in crash, after i leave CC fdc, insert exp 32k ram, horizon card and TI99 working. Finally i try at insert again CC-FDC and TI go in crash. Leave CC fdc and insert original TI fdc and TI work perfect.. Then CC rs232 and CC FDC no working together and it is strange!!

 

If i leave CC rs232 and insert TI rs232 and insert CC FDC ti99 is working!

Wasn't there an issue with the earliest CorComp RS-232 cards causing this problem? I seem to remember a mod in one of the Smart Programmer's that resolved it. . .
