I have a Cincinnati Arrow 500 VMC with a Acramatic 2100 (A2100) control Pentium 1 (75 mhz) with dual motherboards. I want to convert the PC portion to a modern Intel 775 CPU Motherboard. The Control is Windows NT based.

I changed the Cmos batteries last week And suddenly the machine wont work. i did flash the bios on the rt board. I also reloaded the current software in the control from the hard drive

This is a portin of the Siemens Email (they auqired the control from Vickers then stopped making it)
A failure here usually means the WSCPU (1st motherboard) $2300 is at fault - it cannot communicate with the (2nd motherboard) RTCPU..

(My controll errors)
The NC Engine Base test failed every time.

Hardware Diagnostic Startup Status

Bridge board (RI) #0 Results Unkown
High Density I/0 #0 Results Unkown
Pendant Panel #0 Results Unkown
Read Time Processor #0 Results Unkown

I think updating the motherboard to modern low cost parts would be a good investment. My machine uses Kollmorgen servos and servo amplifiers it has about 10 serial ports and two or three larger ports. I have been looking on the web and theres a lot of specialty pci serial port cards. Im not sure if there will be driver issues also.

Anyone out there thats done something like this before?

Thanks Mark

Hello there, I ve been playing with a vickers pc for the last 10 days so here is something you can try

1-take the RT MB off the machine

2-find an old ISA VGA card and push it in one of the slots

3-find an old power supply and attach it to where you give MB power

4-old keyboard or a converter so you can use the MB

when you flashed the BIOS of the RT MB it back to default settings waiting for a floppy drive and a keyboard

so get in the Bios and change the settings to

1-NO Floppy
2-Halt ON NO ERRORS

that will make it go fine and the led on the right hand side on your bridge board should go off in a 5 secs during start

wish that helps you mine was a little bit further problem

Any news mate?
