All-day 'Virtual' Acorn session #4, Saturday 6th June 2020, 9am - 10pm - NOW FULL

Post by sydney » Tue May 19, 2020 4:07 pm

It'll soon be time for the next all day meeting so please respond in this thread if you are interested in attending. 9am - 10pm is the running time and we are aiming to cap the event at 50 people.
The all day events tend to be a bit more structured but there are still opportunities for general discussion amongst the attendees so if there is something you'd like to talk about let me know and I'll make sure everyone knows about it.

Talks summary


Session 1 - Morning

10:00 - 10:45
Floppy disc preservation: HFE & Greaseweazel (Daniel J)

PCB Design: Tips & Tricks from dp11 (Dominic P)
dp11 wrote: With lots of people designing PCBs some for the first time, I'm going to share some tips and tricks to help make your boards electrically better. Even though retro clock rates are low , actually one of the most important parameters is slew rate of signals. Modern chips even if clocked slowly have very fast slew rates which can cause problems.

Items I hope to cover :
  1. Loop area : Why it is important especially on 2 layer board
  2. I'll show a a few simple tweaks to a design to keep loop area to a minimum
  3. Via placement to minimize loop area.
  4. Decoupling capacitors
  5. 4 layer board stackups and why the traditional stack may not be the best.
  6. A few little design tips to increase reliability for boards being hand soldered.
  7. Questions
12:00 - 12:30
Dave Hitchins: PRES/ACP - Career before, during & after! (daveejhitchins)

I might not make it home until 7.30pm, so pencil me in for after that point, just to be on the safe side.

The first of the afternoon slots have been confirmed: expert Acorn Electron programmer 0XC0DE will give a talk and demonstration relating to the many, incredible graphics demos he's created for the "Elk".

He will also cover the conversion of Dave Footitt's beautiful arcade adventure Mountain Panic from the BBC Micro to the Electron.

This has currently been allocated a 45 min slot at 2pm.

Hi Can I also be placed on this list. I will visit the home computer museum in Helmond the Netherlands. We can ask the museum director if we can show the Acorn System one in detail and stream it live.

Oh, that sounds REALLY cool, Timo.

Do you think there's any way you could you get the necessary permissions in advance? As we could allocate a slot on the programme for you if so ...
