 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

For those of us who are beyond a certain age and still haven't succumbed to one of the various memory failures that abound with age, here is a story about CP/M. If you have to ask what CP/M is then this story may not be for you. This year is the 40th anniversary of the creation of CP/M. We have come a long way in those 40 years. The link is to an article by David Gewirtz from ZDnet and has a link in it to the Computer History Museum. That link is the one to follow after reading David's story. You will find that link part way through and also in David's last paragraph. |

I still have lots of CP/M books and a CP/M rom for the Microbee. Do you need a copy of Wordstar? Jim VK7JH MMedit MMBasic Help |

Fascinating read. How far we have come. Smoke makes things work. When the smoke gets out, it stops! |

Or maybe Visicalc - an American colleague of mine in Boston went to MIT with the bloke who "invented" Visicalc. Greg |

sh*t, Wordstar, visicalc.....I guess I am officially gettin' on. Don't poo poo conspiracy theories. Remember that everything ever discovered started somewhere as a theory. |

I also have lots of info on cp/m Jim, including a full set of the original Digital Research manuals. I also have full listings of zcpr2, an updated cp/m environment operating system. I had a fergusson bb2 with dual shugart dsdd 8" floppy drives and a honywell monitor and kbd but all the hardware got lost in a move some years back  except the 8inch floppies themselves which I still have (cp/m, zcpr2, wordtar, visicalc, a database of sorts, basic, forth, z80 assembler and full source for zcpr2.)
Anyone out there with a bb2 stiĺl operational? Doug. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

I thought they were 7" floppies Doug, or was that a later breakthrough! |

There actually were no such things as 8" floppies. All the guys with 5.25 inch floppies just claimed that they were 8 inches. Micromites and Maximites! - Beginning Maximite |

Oh boy - I feel embarrassed to say I'm used to 3.5" floppies 
Actually, I seem to remember they referred to them as 'Hard'  (that makes it even worse I guess!!!) For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

aka Stiffies ho hum. I wrote drivers for CP/M (*), i.e. BIOSes, more than once. Going from 48KB to 64KB RAM was so impressive. And single-sided 8" floppies to DS ones - luxury. Hard to believe. I rather liked DDT. I think PIP got its name from the DEC utility of that name. (Peripheral Interchange Program, ye gods what a silly name.) (*) also for MP/M, CP/M-86, MP/M-86, MS-DOS, UCSD p-System, Coherent, XENIX and various others. John |
