From: Larry Seiler <Seiler@mit-xx> There is a company called SVC (Silicon Valley Corp, in Sunnyvale CA) that sells a program for the Rainbow 100 that formats disks. It sure beats me why DEC didn't make disk formatting available if the hardware is capable of it. Details on request. Larry -------

DEC didn't include a formatting program with their PC's and this permits them to pick up the profit in supplying disks. At $6.50 a throw, there is a lot profit per disk. They further enhance that by having the system allocate space in 2K chunks so that on average there is 1K waste space for each file, and of course, they don't push use of SQ/USQ or LU to compact things. Their latest rip off of their customers was to remove the initialization of the communications port in the boot-up of the Rainbow. Thus, only the expensive DEC supplied communications programs work. On mine, TERMINAL READY to the modem is set on boot; on the latest models it's not. The TERMINAL READY signal can only be brought up by an 8088 assembly language program that hits the secret hardware registers with secret codes (DEC does not supply any technical information at all for the Rainbow). There is no CP/M call or program offered to initialize the port. [the grapevine says that you hit 8088 port 02H with a 05H, and then port 42H with an E0H] Mel Haas , houxm!mel
