Hi Richard I was just looking for Synertek stuff and came across your page on the R65 and SYM-1. I noticed that you had the manual for PL/65. I'd been looking for this info for some time. I have the PROMs but didn't have the manual. I think I have the Rockwell manual for the Forth. I'm not setup to scan stuff but maybe we can setup someway to get them scanned. I live in Santa Cruz Calif. I've been getting a floppy disk interface up and running for the SYM-1. It is a slow project that I've been fiddling with for some time. I have one of the PerSYMone ( I think that is the right spelling ) FDC-1 cards that is intended to work with the SYM-1 monitor ROM. The card I had came from Synertek and had all the socketed parts removed. I've been collecting the various pieces needed to get it running. I located a dump of the original ROM and also a modified DOS that can be used as well. I've been having problems finding a DP8303 bidi-bus buffer but I think I can work around that. I disassembled the code on the ROM and figured out what the address decoder PROM needed ( a 82S129 ). I'm at the point now that I just need to connect up a bunch of stuff ( powersupply, KTM-2, SYM-1, FDC-1 and floppy drive ) to try it out. Dwight
