I'm having problems programming a VR memcal. The chip is a 014 67633 which I believe is a 27C512. I have erased it using UV and it shows up as empty but when I try to program using a Willem programmer it just keeps giving an error. I have selected the 27C512 as the device and reset all the dip switches and have hit a dead end. In the past I have programmed around 25 of the VN style memcals with the 27C128 chip without problems using the same gear. Any ideas would be helpfull or even someone around Brisbane that could take it on as a job.
