Now we know - where Woz go his idea from !!!

and the best joke is:

it´s NOT a COMPUTER - not even a "homebrew" one....

it´s just a simple clock......

the amazing thing in this clock: the counters have been made instead with couters / dividers with simple gates....
the entire stuff in this freezerbox was later integrated in a single RTC-chip !

but it´s a great graveyard of old TTLchips...
and it´s for sure not worth that price....
100 TTL-chips worth about max. 100 bucks
transformers another 50 bucks
but you´ll get a lot of wirewrapsockets....

Hello Steven,

WOW for what ? For the wiring of that graveyard of ICs
or
WOW for identifiying what the graveyard is good for if it would powerup correct ?

I´ve done something similar in the end of the 70´s when i built an electronic roulette table with
combined logic to display the winning fields of the table.... i spent nearly one week on that project
and we made the fields with colored plastic and 24 volt light bulbs driven by transistors.....

press a button once a second and the generator lets the light bullit spin about 200 to 250 seconds more
ending with a random generated number between 0 and 36

and the the logic contained about 80 ICs as logic gates and more than 200 diodes to decide which fields in the table light up as winning fields....

the powersource requested 4 Transformers
2 transformers 6 Volts regulated to 5 Volt DC / 10 Ampere
and 2 transformers with 24 Volt AC regulated to 24 Volt DC / 12 Ampere ........

i would be amazed if that table still exists....

"WOW" to the amount of older chips.
