+
+The BR1000Ms were Brazilian professional computers.
+
+The BR1000M's hardware was the same as [Cromemco's](/museum/cromemco-system-i-ii-iii/), and the so-called BR1000 operating system was in fact Cromix, a UNIX flavor designed to run on Cromemco's hardware.
+
+Two models of the BR1000M were available: one with a Z80A processor at 4 MHz, capable of handling up to 4 dumb terminals, one of which was also used as the system console; and a "high end" model with a Z80B processor at 6 MHz, capable of handling up to 2 more terminals.
+
+RAM size was one 64-KB system RAM board plus one additional 64-KB board for each terminal, all plugged into S100 slots. The first machines used 8-inch floppy drives, later upgraded to 5-1/4-inch units and, eventually, to 5- or 10-MB Winchester hard disks, keeping a floppy drive for data backup.
+
+The picture shows a late-model (1985) terminal; that casing, designed by Brascom's industrial director (nickname Bubby), earned him a prominent design award. Unlike previous models, this one was capable of displaying graphic characters such as lines, corners and blocks.
+
+In 1985, Brascom introduced a 6-MHz Z80B-based microcomputer running the CP/M operating system. This computer, called Foxy, was equipped with the above-mentioned late-model encasing and two external 5-1/4-inch floppy drives. This product never quite made it, due to Brascom's increasing financial problems and its final closedown in about 1986.
