From mboxrd@z Thu Jan 1 00:00:00 1970 From: ghisolfo.m@gmail.com (Michele Ghisolfo) Date: Fri, 1 Jan 2016 18:42:06 +0100 Subject: [TUHS] Unix Circuit Design System In-Reply-To: References: Message-ID: It compiled fine in 4.2BSD (inside simh). I telnetted in with an xterm in Tektronix mode and draw works like a charm. I even got the xterm to graphically display some logic gates. There's only some minor fiddling with environment variables to be done. 2016-01-01 16:45 GMT+01:00 Michele Ghisolfo : > Yes, but earlier you pointed out that it does not emulates two wheels > of the terminal.
