I posted a message on a Microsoft community forum, and got back a reply saying to try turning off some of the Windows Services such as Superfetch. I tried this and discovered there are some services which slow the 1802sim down significantly. This is weird given that the CPU is showing almost no activity (98%+ idle time) in Task Manager - which in itself warrants further investigation. What made the difference for me was 'Tablet PC' Service in Win 7 and 'Touch Keyboard and Handwriting Panel Service' in Windows 10. You can also wring more speed out by turning off Windows Search service, but that slows down things like searches for apps and Control Panel items etc. I've now gotten the Windows 10 Toshiba Kira into sub-second territory like the older Win 7 machines. I also set it up to dual-boot into Win 7. Win7 is still slightly faster than Win 10. WPF is still unbearably slow compared to WinForms.
User Manual For The Cdp1802 Cosmac Microprocessor Software
The RCA CDP1802 (aka RCA COSMAC) is an 8-bit low power microprocessor introduced by RCA around mid 1970's. It was used by many popular early computers (like all the COSMAC ELF variants & VIP in the USA and Telmac in Finland) and has also gone to space controlling satellites (military version is highly resistant to radiation and ESD). The RCA CDP1802 COSMAC microprocessor is a one-chip CMOS 8-bit register-oriented central processing unit introduced in 1976. The 1802 is interesting for a number of reasons, not the least of which is the fact that it uses static CMOS circuitry, meaning it has no minimum clock frequency. The RCA-CDP1802 is an LSICOS/MOS 8‐bit register-orientedcentral-processingunit (CPU)designed for use as a general-pufpose computing or control element in a wide rangeof stored-programsystemsor products. RCA CDP1802 – as 2013 version. Probably the first 8Bit CMOS Processor, introduced about 1976. But how would a time warp of 37 years from 1976 to 2013 affect performance? Hardware description languages like VHDL and Verilog can describe functionality for hardware for implementation into FPGA and ASIC.
