[sdiy] Mystery chips

[karl dalen]

The ay5 chip might be a 3 osc square wave "low pin count" chip.
Several AY chips was released as LPC variants of the 40 pin dip sound chips.
but it can aslo be a cpu pheriphial chip of some sort.
Then there is several logic chips 7408, 4082,LS38etc.

Ahh, a swedish RIFA chip!! Splendid! :-)... Have no idea what it is tough!

Some of the Signetic chips might be microprocessor pheripherial IC.
The fairchild is a 4011, you really got some very old logic here! .-)

The TMS4036 are a digital IC it might be a, "yet" another speach chip,
texas has made loads of them, i even have one that Texas them self was 
not avare of!!

But its more likely its an odd memory chip, eirther a DRAM or PROM 
for the speach chip!
The TL3741 might be a quad 741 from Texas!
The 320002 i have seen before, it might be a reference or a 
dual bipol tranny, cant remember wich!
