Eichin) Newsgroups: comp.os.cpm Subject: re: Z80 emulators Message-ID: <9011021956.AA19611@E40-008-11.MIT.EDU> Date: 2 Nov 90 19:56:21 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 17 So how many people are interested in collaborating on CP/M or Z80 emulator development? I had a Z80 emulator on my todo list for years, and then Nick Sayer came along and announced his, so I went and helped him test and debug it, rather than duplicate effort; however, there are a number of different strategies one might use, and there's room for many other designs (in its current form, with all of my additions, Nick's is quite useful for debugging, but it is dismayingly slow. A faster implementation might use a different strategy but not be as good at debugging.) If you're interested in actively coding or designing and discussing strategies for particular instructions or for the overall implementation, send me email (eichin@athena.mit.edu) and if there is enough interest, I'll set up the list. _Mark_ MIT SIPB Member/N1DPU/Z88 Hacker ps. My motivation includes possibly doing a simulator of the Z88, for development there too. If you're interested in that, consider joining the z88-hackers list .
