I got a book with a CD a while back and a friendly forum member with the same one uploaded the CD to dropbox so I could download it. I'm old enough for 8 inch floppies, cassettes as storage and not quite old enough to have to toggle the boot loader in, thank goodness :) Agree with grey beard icon --- End quote --- Ask and you shall receive: --- End quote --- I like that. Needs to be added. The irony here is that Bob would have tossed all the computers from a roof :) |

They get a lot of attention from people who are seeing my place for the first time. I wish I had an old 8" HD or two to do the same with. Lots of old time geeks among my friends. I never used paper tape, but I did use punch cards for a short bit. As for toggling in the boot code, the first computer I used needed it to be done. Until I added a paged EEPROM storage bank to it and gave it a resident OS. Oh, I also eventually reimplemented the whole thing from discrete resistor transistor logic and core memory on hundreds of 100mm x 60mm cards to TTL logic and SRAM chips using 4 12" by 18" wire wrap circuit boards. Had to retime the whole thing because it was running much faster. |

TI980 minicomputer around 1976. The way it was set up, one toggled in a minimal boot sequence to read from the paper tape reader. The paper tape loop then loaded a program to read the first sector of the single platter 14 inch cartridge disk drive. That in turn loaded a proper operating system and the TTY became the console. Another minicomputer (Sigma 2) I also had access to had a literal patch panel for the cold boot sequence. No toggling required. Not that I ever had to actually reboot that one. |

These beasties: The controller for these was one of these big cabinet things and it took an 8" floppy and some toggling to get it up and running. Mind you, the 3370 series was introduced in 1979 and had a capacity of over 500MB. later models had over 700MB. --- Quote ---Agree with grey beard icon --- End quote --- +1 |

I had a circular saw that looked less scary than that :-DD |
