Hello everyone,

Good turnout with 19 attendees and lots of huddles-of tech-talk. $26 
collected and transferred to BR05 account.

The recently prompted email regarding equipment donations to the trading 
table has resulted in quite a pile of ‘new’ equipment. Just to 
reiterate; yes donations are welcome, but not CRT, printers or toner.

With thanks on behalf of the group,

Mark Atherton

===========

Ben brought in his freshly made plastic vacuum-former, along with some 
1mm PETG plastic sheet (Mulford Plastics), and a managed a successful 
live demo.

William gave us an update on his home-cooked (small scale integration) 
computer project. LDRs are due in anytime soon, and will form the heart 
of the paper-tape- reader. See GitHub WRFleete/DiscreteLogicCPU for 
further details of this project.

Rudy brought in a 2k bit core-store (~512 bytes); huge thing, about 
500x400mm. Unfortunately damaged by the previous owner, but fascinating 
as usual.

Andrew E brought along his PI-based battery management system. The 
original PASCAL has been translated into Python, and was demo’d using 
the video projector.
