Is anyone interested with the Z80?

COMPACT

The Z80 is still manufactured today and I was wondering whether there is any interest for a community or discussion group.

  • Omg. Doesn't sound like much, but I actually have a working serial interface working with basic working. Thanks for everyone's help but asking my somewhat dumb questions.

     

    Where do you people usually get your components and parts from?  I live in Connecticut, USA. I have been ordering from jameco. They are located in California.  Shipping is usually 4-5 days. Mouser is closer being in the mid West . Also digikey is in the same location. What area your experiences with these places or others in the us?  Shipping is usually $5 from jameco.

     

    Thank you again. I'm sure I'll have more questions, but I finally have something working and doing something.

    That's really quick to write your own BASIC!

    Did you know that 8080 Microsoft BASIC was written on a PDP-10?

     

    Please post some pics, vids and schematic diagrams of your new system in action.

     

    I get many of my components from Element14!

    I hunt around for obsolete components that are not stocked by Element14 but beware of Chinese counterfeits!

    Hi everyone,

     

    I stumbled on these old beauties today,

     

    Good ole 68,000uF 16VW capacitors with screw terminals as used for S-100 Bus systems.

    These capacitors are the size of Soda Pop Cans and are used as filter capacitors for the unregulated +8V power supply.

    Back in this era the power supplies were comprised of a giant transformer, full wave diode bridges and large filter caps.

    Transformers had 3 sets of secondary windings. One for 8V with a large current rating (anywhere between 5-30A) and two 12V outputs with about a 1A current rating.

    Every S-100 board had its own onboard voltage regulators that decanted power from the common -12V, +12V and + 8 V power supply lines.

     

    It could take next to forever for an unpopulated S-100 frame for the power to dissipate.  It was common to install bleeder resistors across these capacitors on test S-100 power supplies for faster power dissipation.
