Q) Does Glenside accept credit cards as payment at the CoCoFEST?

  • A) Yes, but not all vendors do.

Q) What should I bring?

  • A1) Musical instruments.
  • A2) We hold two auctions, so bring stuff you want to keep out of landfills to go into the auctions, and bring some spending money or a credit card to spend on auction items to add to your collection that you didn’t have a chance to purchase when you were younger.  The money from the auctions goes to help pay for the CoCoFEST!  Buy books, manuals, software, cables, joysticks, disk drives, computers, fanfold paper, and such.  If you bring an item and it does not sell, then consider taking it back home with you.  Printers generally do not sell, and no one wants to be stuck with them.
  • A3) People are selling hardware and software (outside of the auction) so bring some spending money for that.
  • A4) Charge the battery in your camera and bring it.
  • A5) Bring hardware you want repaired or upgraded.
  • A6) Bring your ideas.
  • A7) Chicago has toll roads, but toll booths are no longer manned. Many toll booths no longer accept coins. If you do not have an electronic IPASS/EZ-PASS unit or sticker for paying tolls, you can pay by plate by signing up at or the Tollway Authority can mail you an invoice that you can pay online. Or use your GPS and avoid toll roads altogether.
  • A8) An ice scraper for your car, just in case.
  • A9) If you are driving, consider bringing a spare television (TV) or monitor. CRT monitors can be useful too.
  • A10) Do you have an old landline phone, phone wire, fax machine, or modem, that you can bring to the CoCoFEST!?
  • A11) Do you have some old items from Radio Shack or the 80s that you think people would like to see again? Like an old VCR tape of some old movie.
  • A12) Bring some 1980s-style candy to the CoCoFEST! Do you remember Moon Pies?
  • A13) Buy something in the auction, play with it for a year, and put it in next year’s auction as a tax write-off.

Q) What should I bring for AC power needs as a vendor?

  • A1) Bring extension cords, power strips, and tape to hold them down.
  • A1) Consider bringing a number of 8-inch extension cords. They are good for dealing with wall warts and other such things. For example:
  • A2) Consider bringing a straight-on 8-inch extension cord. They are good for when you need a plug to be straight-on and not at an angle. For example:
  • A3) Consider bringing a power squid. It will allow you to connect several wall warts, USB chargers, and other things, no matter the orientation of the plug. It should look something like this:
  • A4) Consider bringing a ground cheater plug.
  • A5) Consider bringing a smart plug with power monitoring capability, an AC voltmeter, or an electrical ground checker. to help diagnose AC power issues.
  • A6) Think about solutions to running a high power appliances like a 1500 watt hot air gun. This could cases cause a circuit braker to trip. But a simple power management system can be made with Home Assistant that could solve this problem. You will need two smart plugs with power monitoring and an Uninterruptible Power Supply (UPS). When the UPS output power exceeds 200 watts the UPS input power is disconnected. And when the UPS output power drops below 100 watts the UPS input power is restored.

Q) What should I bring for DC power needs as a vendor?

  • A1) Consider bringing a USB squid cable like this:
  • A2) Consider bringing a USB data blocker charge only cable. I always carry one with me. It is useful for when you need to use a public charging station but do not want your personal data to be stolen or have malware installed on your cell phone. Mine looks like this:
  • A3) Consider bringing a single port 100-watt or more USB-C charger with Power Delivery (PD) and a 100-watt or more USB-C cable. Retractable cables can be nice. And cables with more than one connector on the other end can be nice. You may be able to run a laptop computer off of this. And with a little work you can run a CoCo off of this. Also you can offer to charge someone’s smartphone.
  • A4) Consider bringing a USB power meter.
  • A5) Consider bringing a USB-C Power Deliver (PD) to adjustable power supply converter. Or bring a USB-C PD dummy breakout or USB-C PD. adjustable voltage power trigger module like this:
  • A6) Consider bringing an adjustable power supply.
  • A7) Consider bringing a USB power bank. I have a USB power bank that accepts four rechargeable 18650 cells and outputs a USB charger. I have extra 18650 cells for when the the battery of 4 cells dies.

Q) Is free Wi-Fi available to all at the CoCoFEST?

  • A) Yes! The hotel Wi-Fi may require you to agree to the terms of service and some devices like an ESP-32 serial-to-Wi-Fi may not be able to do this. Some smartphones can be used as a Wi-Fi hotspot to get around this problem.

Q) What kind of computer should I bring to show at the CoCoFEST?

  • A1) CoCos, Tandy, TRS-80, Radio Shack, and clones.

Q) Will there be an opportunity for non-vendors to swap/trade/sell hardware?

  • A) The entire event consists of trading, swapping, buying and selling software, hardware, other stuff, stories, anecdotes and knowledge. I think you would be hard pressed to not find time to do this.

  • A1) You can take a rental car, taxi, Uber, Lyft, or limo.

  • A3) Don’t speed through road construction sites even on the weekend when workers are not present, unless there is a sign that says it is ok. I think I am telling you right about this.
  • A4) In the suburbs of Chicago, I have seen a lot of beggars standing at an intersection with a stop light begging for money. I do not give them money. I want to be ready for when the light turns green.
