===== Presentations 2019 ===== Saturday and Sunday in parallel with the exhibition ===== Presentations 2018 ===== Samtags und Sonntags in Parallel mit der Austellung ==== Sa 13:00 Going out with a ROAR – Royal Precisions RPC-4000 ===== The RPC-4000 was launched in 1960 as the successor and big brother of the LGP-30. The manufacturer stuck with the proven formula for success, developing another compact, low cost “personal computer” based on magnetic drum memory. Too little, too late, as it turned out: While various clever design tweaks got more performance out of the magnetic drum architecture, the competitors launched new computers based on ferrite core memory at the same time. This new breed of machines left the RPC-4000 in the dust, technically and commercially. The talk will present the RPC-4000 as one of the last magnetic drum “dinosaurs”, and will briefly describe my project to resurrect this machine via an FPGA-based replica – and to locate its lost software.

( C64 sound interface device) A guitar controls the SID Chip i.e. the very dynamic Chiptune Sound. Recognisable but nevertheless a fresh Sound. You don´t even have to know how the play the guitar, just grab the snares and something musical will come out ! Overall we just want to show that the SID stills produces an impressive sound and are still being used in new developments. // Andrej Westermann // ==== Sa 15:00 / So 15:00 Gigatron Selbstbau TTL computer ===== Marcel demonstrates his TTL -bases 8-bit Computer,which he developed himselves. Despite being build from low level TTL chips hist computers sports a video-output and a BASIC-interpreter. This computer is available as a kit, details are on https://gigatron.io // Marcel van Kervinck // ==== Sa 16:00 / So 16:00 Silizium Planar Technologie ===== „Behind the integrated circuits stands a Swiss citizen“. I will talk about the development of the silicon planartechnology, how this is still the basis used today, and how it might develop in the future. // Robert Weiss // ==== So 12:00 Unibone ===== "UniBone" - a Linux-to-UNIBUS bridge, based on the BeagleBone Black. It is supposed to be a development platform for device emulation. At the moment it can emulate memory, emulate an RL11 controller with 4 RL drives attached, and act as UNIBUS hardware test adapter. There are some web pages at http://retrocmp.com/projects/unibone // Jürg Hoppe // ==== So 13:00 Super-Nintendo ===== Sven delves deep into the innards of the Super-Nintendo console. // Sven Huerlimann // ==== So 14:00 PDP11-Hack ===== Peter Schranz discusses the development of the PDP11-Hack : a recently developed PDP11 based on DEC`s J11-chip. // Peter Schranz // ==== So 15:00 16:00 ===== Repeat of yesterday´s talks. ====== Vorträge 2017 ====== //Saturday and Sunday in parallel with the exhibition// ==== Sat 13:00 Building bridges over 30 years of technological development ==== Marc describes his experiences on how to keep C64 and Amigas running, using newly developed hardware, finding spare parts and restoring machines. He will demonstrate a C64 with a SD-card adaptor, the Commodore 64 SD2IEC Backpack. Marc will also report on his current project of connecting a current USB-mouse to an Amiga, by using an Arduino DUE. Furthermore he will reflect on the problems facing computer restorers : fading EPROMS, leaky batteries and capacitors. Time permitting we will discuss usage of FPGA. // Marc Schaffer // ==== Sat 14:00 History of game consoles ==== The well known collector Robert Weiss talks about game console development. His poster documenting the computer development will be for sale in the exhibit hall. // Robert Weiss // ==== Sat 15:00 Logarithms as used in calculators ==== Stephan Schwarzmann discusses the development of the calculator, from the earliest beginnings until now. // Stephan Schwarzmann // ==== Sat 16:00 - 18:00 Programming the 8008, 8080 and Z80 microprocessors ==== Neil Franklin talks about programming the 8008, 8080 and Z80 in machinecode and assembler. // Neil Franklin // ==== So 13:00 Building bridges over 30 years of technological development ==== Marc describes his experiences on how to keep C64 and Amigas running, using newly developed hardware, finding spare parts and restoring machines.

(repeat of yesterdays talk). // Marc Schaffer // ==== So 14:00 Basicode ==== Martin Bijl shows Basicode, a means of distributing home computer programs via radio and TV-channel. Differences in BASIC-dialects were taken into account, such that programs could run on a multitude of home computers. // Martin Bijl // ==== So 15:00 Super-Nintendo internals ==== Sven Heurlimann delves deep into the innards of the Super-Nintendo games console. // Sven Heurlimann //
