It would be great if someone would like to review my effort and suggest improvements. I would be more than happy to do so if anyone is. I have not attached my code here as I'm not sure if anyone wold be slightly interested. It enables the use of a C compiler on the Prop !ДЇor that last point there is BDSC for CP/M written in 1979 which is now free and open source ( ) It shows off the Propellers capabilities.Дў. This must be the most useless project ever described in this forum however it does have some interesting points:ДЎ. My current hold up is actually getting a CP/M boot disk image onto an SD card.

There is still someway to go before I have CP/M booting up from my SD card. So far I have managed to get as far as getting the CP/M sign on message to display followed by the command prompt. The Command Processor (CPP) the Basic Disc Operating system (BDOS) and a BIOS. On top of that I have origanal CP/M components loaded from files into a DAT section. Amazingly I can fit an interpreter for the entire 8085 instruction set in one COG! The result is that my first ever Propeller program is an 8085 emulator written in PASM.

#ALTAIR 880 EMULATOR FOR MAC SOFTWARE#

Why not save all that hardware construction effort, junk the 8085 CPU, RAM and ROM chips and implement the whole thing in software in the Propeller ? Very easily it could provide the console output on TV or VGA. My first thought was to use a Propeller to implement those peripherals.

#ALTAIR 880 EMULATOR FOR MAC SERIAL#

This of course needs some peripherals like serial ports and disk drives which I really don't want to build the old way. Now, I have a 'retro computing' hobby project going on which is to build up a little sytem with an old Intel 8085 processor some RAM and some ROM and get running the CP/M operating system. Something that uses all it's power to the max. Something that it can do with ease that other controllers cannot. So I have yet to envisage the ultimate killer application for it. It's also has severe limitations in the lack of general purpose memory and the tiny spaces available for PASM in each cog. The Propeller is totally facinating in that the thinking that went into it's architecture is so far 'out of the box':The multiple processors, the spin interpreter, the lack of interrupts, the required use of (normally frowned upon) self modifying code in PASM, the deterministic timing etc. Having been involved in embedded systems since 1982 and hence been through many generations of microprocessors, microconrollers and associated operating systems I could not resist looking into this new fangled Propeller chip.
