Last time was a blast, I'm definitely going to be there again. The larger room had plenty of space for more people and tables too. I'll be able to add a couple of things :) On Fri, Sep 27, 2024 at 1:19 PM Ryan Stapleton via vcf-midatlantic < vcf-midatlantic(a)lists.vcfed.org> wrote: > Hello All, > > I now have a date for a late fall Computer meetup in Chantilly, VA. 17 > November 2024 @ 1-6pm > > The Chantilly, VA Public Library. > > A link to my website that has some information.

Folks, I’m looking for a case and keyboard for an Amiga 500. I have a very nice Amiga 500+ motherboard that needs a home, and I don’t see a lot of good options available. If anyone has spare that they would be willing to part with, please let me know. Thanks! – Alex

Re: [vcf-midatlantic] OT HAM LICENSE

It's hard to find time to learn as I'm doing so much for VCF, my job, etc. as it is. I will put it on my list of things to do which is extensive. I will start with the M.O.R.E. project which is run by Dr. Rebecca Mercuri: https://n2re.org/m-o-r-e-project I can make it happen when there is a lull between events or days where schools are closed and I'm not working.

Repair workshops for 2024: Sep, Oct, Nov, Dec.
by Jeffrey Brace 22 Sep '24

22 Sep '24

Yes. There are two repair workshops in October. First one is Oct. 5 & 6 <https://docs.google.com/spreadsheets/d/1onB9_JVSdS3xCxQSOitBgIXSe6K2dbcCtjq…> Second one Oct. 26 & 27 <https://docs.google.com/spreadsheets/d/1tnPdmCYFA6-Y3y28tVcdzTXKqHaArx_1VFl…> Normally I space these things out, but I had to move it twice: the second one was originally on Nov. 9, then Nov. 2, now Oct. 26. So since there is interest and there is space in the schedule, I will schedule one for November on Nov. 16. This is 3 weeks after the Oct. 26 one and 4 weeks before Festivus. So it should be space as well as possible. Nov. 22 is an alternative date if anyone feels like that would be better. No repair workshops for December. Any questions? Comments? Ponderings? Take care!

Yes. There will be a repair workshop Oct. 26 & 27. As stated by others the website was updated, but not the Google Sheet. Sorry I missed that and for the confusion. I also was waiting to announce the *that* repair workshop because I didn't want to overload people with information with three different things. I've found some are easily confused. I always do a repair workshop with the swap meet so it makes it more worthwhile for those driving from far.

This page says workshop on 26 & 27th so now have two workshops in October. https://vcfed.org/repair-workshops-at-infoage/ Spreadsheet itself says nov 2-4. https://docs.google.com/spreadsheets/d/1tnPdmCYFA6-Y3y28tVcdzTXKqHaArx_1VFl… My take was the workshop moved with swap meet and no event now in November. Think spreadsheet is wrong but letting someone official correct.

Next Repair Workshop Oct. 4 & 5
by Jeffrey Brace 22 Sep '24

22 Sep '24

There is someone looking to make 8" disks from images that he has. He recently acquired a fully functional IBM 5110-3 (or 5120) with dual 8-inch disk drives. He found the image files to make 6 disks with various applications for this computer. Is there someone that can make the disk images for him and bring to the repair workshop? Thanks! Jeff Brace VCF National Board Member Chairman & Vice President Vintage Computer Festival East Showrunner VCF Mid-Atlantic Event Manager Vintage Computer Federation is a 501c3 charity https://vcfed.org/ <http://www.vcfed.org/> jeffrey(a)vcfed.org
