Still got a CNC milling machine on DOS 6.2 Works great and if I upgraded to say Mach 3 i would loose a few things like a one line G Code for thread milling. |

It was "programmed" through bat switches that lit up grain o' wheat bulbs -- until I finally got a Flexowriter hooked up to it... I suspect that your floppies were 720 kB rather than 720 mB. [My first floppies were 8 inch 32 kB beasties.] --- End quote --- ... oh no...not Friden Flexowriters .... they were a nightmare to work on. My first printer was a Creed 54N 'hunt and peck' - just post war, driven at telegraph signal voltages (80-0-80) which I interfaced using a home made opto-coupler - an OC71 germanium transistor with the paint scraped off the glass case pushed into a bit of Hellerman rubber sleeving with an led pushed into the other end :bugeye: Eventually I got my hands on a Shuggart 801 8" floppy drive with all of 128k kbytes but that wasn't until the mid 70's when I built my S100 / CPM system. |

Lew - I think you are right about the 720 kb. floppies. As I recall they were huge and would allow me to do any number of things. I also worked with a sliderule but haven't yet used an abacus - I have used my fingers and toes on occassion - does that count as old :D John |

Ok I will get modern 20mb HDD My first foray was a home brew zilog z80 beast with CPM I then home brewed a cuts interface for tape followed by a disk interface for the early single sided 8 inch floppy. Then hand coded a boot strap EPROM that lived at A hex address I have forgot and then bought poly dos on disk Printer a old Teleltype terminal hooked on to a spare keyboard bit again hand coded routine patched into the correct position Speed well it was a Z80a so 4 meg Those were the days Colossal Cave anyone Stuart |
