Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical technology relics that the Frank Sharp Private museum has accumulated over the years .

Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.

Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

Every CRT Television saved let revive knowledge, thoughts, moments of the past life which will never return again.........

Many contemporary "televisions" (more correctly named as displays) would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities..... and without considering........picture......sound........quality........

..............The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory........ . . . . . .....
Don't forget the past, the end of the world is upon us! Pretty soon it will all turn to dust!

Have big FUN ! !

SDA 9380-B21
Enhanced Deflection
Controller and
RGB Processor

1 General description
The SDA 9380 is a highly integrated deflection controller and RGB video processor for CTV receivers
with 15 to 19kHz or 31 to 38kHz line frequencies. The deflection component controls among others
an horizontal driver circuit for a flyback line output stage, a DC coupled vertical saw-tooth output
stage and an East-West raster correction circuit. All adjustable output parameters are I²C-Bus controlled.
Inputs are HSYNC and VSYNC. The HSYNC signal is the reference for the internal clock
system which includes the=χΝ=and χΟ=control loops.
The RGB processor has two YUV/RGB inputs and one RGB input. One YUV/RGB input and the
RGB input are for SVGA and text/OSD with fast blanking. The RGB output stage has two control
loops for cut off and white level with halt capability in vertical shrink modes. An overall Y output and
an adjustable delay of the RGB outputs related to this signal are suitable for a scan velocity modulation
The supply voltages of the IC are 3.3V and 8V. It is mounted in a P-MQFP package with 64 pins.

1. Introduction
The Micronas SDA 55xx TV microcontroller is dedicated
to 8 bit applications for TV control and provides
dedicated graphic features designed for modern low
class to mid range TV sets.
The SDA 55xx is a microcontroller and single chip teletext
decoder for decoding World System Teletext data
as well as other data services as Video Programming
System (VPS), Program Delivery Control (PDC), and
Wide Screen Signalling (WSS) data used for PAL plus
transmissions (in line 23). The data slicer and display
part of the SDA 55xx supports a wide range of TV
standards including PAL, NTSC as well as the acquisition
of the above mention data services as VPS, WSS,
PDC, TTX and Closed Caption data.
The slicer combined with its dedicated hardware
stores TTX data in a VBI buffer of 1 kByte. The Microcontroller
firmware available from Micronas performs
all the acquisition tasks (hamming and parity checks,
page search and evaluation of header control bits)
once per field. Additionally, the firmware can provide
high end teletext features like Packet-26-handling,
FLOF, TOP and list page mode. The Application Program
Interface (API) to the user software is optimized
for a minimum SW overhead.
The on-chip display unit used to display teletext data
up to level 1.5 can also be used for customer defined
on-screen displays (OSD). The display generator is
able to handle parallel display attributes, pixel oriented
displays and dynamically re-definable characters
The SDA 55xx provides also an integrated generalpurpose,
fully 8051-compatible microcontroller with
specific hardware features especially suitable in TV
sets. The microcontroller core has been enhanced to
provide powerful features such as memory banking,
data pointers and additional interrupts, etc.
The internal XRAM consists of up to 16 kBytes. The
microcontroller provides an internal ROM of up to
128 kBytes. ROMless versions can access up to
1 MByte of external RAM and ROM.
The 8-bit microcontroller runs at 33.33 MHz internal
clock. SDA 55xx is realized in 0.25 micron technology
with 2.5 V supply voltage for the core and 3.3 V for the
I/O port pins to make them TTL compatible.
Based on the SDA 55xx microcontroller the MINTS
software package was developed and provides dedicated
device drivers for many Micronas video & audio
products and includes a full blown TV control SW for
the PEPER application chassis. The SDA 55xx is also
supported with powerful design tools like emulators
from Hitex, Kleinhenz, iSystems, the Keil C51 Compiler
and TEDIpro OSD development SW by Tara Systems.
This support provided by Micronas leads to:
– Shorter time to market
– Re-usability of the SW also for future Micronas
– Target independent SW development based on
– Verification and validation of SW before targeting
and improved SW test concept
– Graphical interface design requiring a minimum
effort for OSD programming and TV controlled know
