The System/36 used virtually the same RPG II, SDA, OCL, and other technologies that the System/34 used, though it was object-code incompatible. Its original displays (at 24×80) were the most popular, and used the same basic screen size used on a number of computer terminals, such as the ADM-3A, VT52, and VT100. A 27×132 display was supported c.1987, but never quite caught on. The S/36 was a small business computer; it had an 8-inch diskette drive, between one and four hard drives in sizes of 30 to 716 MB, and memory from 128K up to 7MB. Tape drives were available as backup devices; the 6157 QIC (quarter-inch cartridge) and the reel-to-reel 8809 both had capacities of roughly 60MB. The Advanced/36 9402 tape drive, c.1994, had a capacity of 2.5GB.
