What Happened in Russia in 1998?

"The third subseries, released in 1984, were analogous to System/370 with some original enhancements, and included 1016, 1026, 1036, 1046 and 1066. ES 1066 had up to 16M RAM and operated at 5.5 MIPS. The fourth subseries had no direct IBM analogs and included 1130, 1181 and 1220. The last machine in the series, ES 1220, released in 1995, supported a number of 64-bit CPU commands, 256M RAM and operated at 7 MIPS, but was not successful; only 20 such machines were ever produced, and in 1998 the whole production of ES mainframes was stopped."
