- Arrives May 1962
- Features:
-
8-bit byte, 64-bit word
- 8 bits: Hamming error correction, used the same memory as the 7090 (two 36-bit 7090 words became 64+8 bit 7030 word)
- Decimal, binary and floating-point arithmetic
- Reliable: acceptance was 90% uptime over a 5-day period
- Instruction look-ahead (four levels deep)
- Branch on bit
- Address indirection to any depth
- Scatter/gather fields in word
-
MCP: Master Control Program ran one job at a time plus input/output wells
- Rented for 2 shifts, 7 days per week
- IBM's Fortran IV compiler hopelessly inefficient, machine runs slower than IBM 7090
- Alick Glennie's team at Aldermaston write three Fortran compilers in period 1962/63:
- S1: Fast Compilation
- S2: Basic Block Optimisation plus Fortran enhancements
- S3: Global Optimisation
