Hi all,
After a very successful day finalising and testing the computer, I have come across an error which I cannot find any reference to.
When generating SMPTE to tape, it stops after around 30sec to 1min with "Error: Code 23"
Prior to this, I have noticed that the SMPTE is generated clocking x1.37 faster than the tape machine counter. I had put down 62sec of SMPTE (by the tape machine counter), though it had generated 1min 25sec on the SSL computer. I suspect a clocking error here in the SMPTE generator, though cannot work out where its master clock comes from, other than pin 63 on the edge connector.
In addition, I have been getting the odd error on booting : "System timer is too slow to control Tape Machine" , and once or twice "System clock not working"
As there is no schematic for the processor board, I'm not sure where to start. Has anyone come across this before??
Any help is massively appreciated.
Anthony.
