Hi,
I have an Intel iUP-201 EPROM programmer which is giving a 'Power Supply Failure' error. I think it is failing a self check for one of the output voltages from one of its uA723 precision regulators, which are set from resistor networks and multi-turn pots. I have checked all the electrolytic caps and they seem fine, and voltages from the linear power supply look reasonable. I have a user manual but no schematic or service manual, so am a bit in the dark as to where the problem is. I found a range of similar manuals here: http://www.intel-vintage.info/inteldevelopmenttools.htm Please can anyone with further documents for the iUP-201 (or similar iUP-200) please get in touch, Regards, John Intel Development Tools - Intel Vintage<http://www.intel-vintage.info/inteldevelopmenttools.htm> www.intel-vintage.info This Site about Intel old staffs like ICs ,Manuals,Tools
