| 24-Apr-08 JDB Added calc_defer() prototype | |
| 20-Apr-08 JDB Added DEB_VIS and DEB_SIG debug flags | |
| 26-Nov-07 JDB Added extern sim_deb, cpu_dev, DEB flags for debug printouts | |
| 05-Nov-07 JDB Added extern intaddr, mp_viol, mp_mevff, calc_int, dev_ctl, | |
| ReadIO, WriteIO for RTE-6/VM microcode support | |
| 16-Dec-06 JDB Added UNIT_2115 and UNIT_2114 | |
| 16-Oct-06 JDB Moved ReadF to hp2100_cpu1.c | |
| 26-Sep-06 JDB Added CPU externs for microcode simulators | |
| 16-Aug-06 JDB Added UNIT_EMA for future RTE-4 EMA microcode | |
| Added UNIT_VMA for future RTE-6 VMA and OS microcode | |
| Added UNIT_1000_F for future F-Series support | |
| 09-Aug-06 JDB Added UNIT_DBI for double integer microcode | |
| 21-Jan-05 JDB Reorganized CPU option flags | |
| 14-Jan-05 RMS Cloned from hp2100_cpu.c | |
| CPU models are broken down into family, type, and series to facilitate option | |
| validation. Bit 3 encodes the family, bit 2 encodes the type, and bits 1:0 | |
| encode the series within the type. | |
