'[OT]: Old Chips was [PIC]: Potato Powered PIC?'

What a great page! The same guy also has the datasheet for some ECL chips
from 1967. Which brings up an interesting point: who on the Piclist has the
oldest chips and what are they?

I have some 5400 series logic (mil-spec version of 7400 series IIRC) with a
date code in 1969 (at least if the datecode worked the same way then as it
does now), but I doubt that is the oldest among this group!

From what I've seen, monolithic ICs were invented in 1959(simultaneously
by Fairchild/National and TI), and entered commercial production in 1961
(but probably very limited production at first), so I am curious to see
what you guys have!

All,

I have some Fairchild RTL 914s, Single, Dual input OR gates, and RTL
923s, JK Flip flops(1 per IC)

from about 1967...these were in a plastic package with 8 leads.

So far, Vern takes the award for the earliest ICs :-)

It's great to see the replies already! I am probably one of the youngest
listmembers (born in 1980) but this old stuff really fascinates me. I got
my stock of "old chips" from a copier repair facility that was clearing out
its old stock. There was some _really_ old stuff in there, including nixie
tubes. It is interesting to see some of the technology that was used in
these copiers, office calculators, etc. Occasionally I use some of these
old ICs. It is interesting to see a breadboard with a PIC next to a 7400
from 1971!

I have several boards from them with ICs on them which have FOUR rows of
pins. They are like a plastic DIP package except that the row of pins
coming out each side splits into an outer and an inner row of vertical
pins. I have all this stuff back at my parents' house so I can't look at
the numbers on them now, but any idea what that package was called and in
what date range it was used? Must have been fairly late as these boards
look highly integrated (looks like a CPU, RAM, and ROM), so my guess would
be late seventies but I'm unsure.

That's got to be pretty hard to beat.

A quote from the Apollo Program Manager in 1966 "... building four
or five prototypes consumed 60% of the country's production of
integrated circuits...".

Integrated circuits were a single, 3 input NOR gate which in 1963
became 2, 3 input NOR gates (Moores law). These were surface
mount packages on multilayer circuit boards in the Apollo guidance
computer. I wonder if they had toaster ovens.

Well, maybe we can consider a vacuum tube as an IC, at least some of them has functions like a bunch of diodes and a triode in the same "chip".

I remember analogue ICs that were done like this. The one I remember
specifically was an RCA quad preamplifier IC, and there were 2 versions of
it. One version came in a 14 pin DIL on .3 inch centres, with all 4 preamps
having identical noise specs. The other version came in the same package,
but with the lead frame bent for .2/.4 lead spacing, but still on .1 inch
pitch, and the leads were staggered in such a manner that the pattern was
asymmetrical. Two amplifiers were spec'd for use as RIAA preamps, and the
other two had different noise specs. IIRC the part number was CA3054.

The packages you talk about in the piece I quoted have leads on a pitch of
0.050 inch I think, which was a means of putting more leads on the package
without the package getting too monstrous.

If you want to see a REAL 'hollow state' IC, check this one out, a
complete radio in a bottle, from 1926.....

While certainly not the oldest, I do have a collection of Intel cpu's
starting with the 4004.  They can be viewed at

Looks like the "Loewe Multi-valves' were forerunners
to the GE 'Compactron' tube series:

From:

http://www.geocities.com/portable_tubes/newtubes.html

In the late 1950's, tube designers still had a few tricks
up their sleeves. General Electric's engineers at Owensboro,
Kentucky introduced the "Compactron."

Compactrons are multi-function tubes, combining diodes,
triodes, and pentodes in various combinations, designed
to reduce size and component counts in entertainment and
industrial devices.

-snip-

GE engineers claimed a two-Compactron radio design
could replace a standard five-tube radio complement
(seven transistors were needed for the same
performance), or a 10-Compactron TV-set could
replace 15 tubes and three diodes or 24 transistors
and 11 diodes.
