I have a weird old ROM from the late 70's that I need to read the data off of. If this is a one-off job, and is not on a low budget, you might want to consider getting it done by some of the device programmer manufacturers. Alternatively, a device tester can be used for the same job. OK I suspect these are NOT really options... Jan Waclawek |
