Can someone tell me a source for the Mappler (or something like it)? That is a device to convert Apple analog RGB to IBM TTL RGB. I have had several requests for info on that, but have not been able to find the device. The model I have, has one IC chip in it, and would be easy to reproduce if the chip ( a PAL) were availble (pre-programmed). Cyrus Roton croton@ridgecrest.ca.us Ridgecrest Apple User Group
