I have been using PALASM during the last 20 years, and only last year swicthed to Abel. I still consider PALASM one of the best tools around, since it allows me to program at the gate-level, not at a logic level removed by many layers from the actual gate level as more modern tools force you to do. I also have a running copy installed on one of my computers. Just drop any questions you have. Maybe you send me privately your PALASM file, and I look through it ? Regards John G. Zabolitzky
