Hi
I did some searches. First I found a company
that is listed as having DTL devices form one of those
master list of companies:
http://www.mathiselectronics.com/
The only thing is that they do not list them on their
web page.
A little nore in depth search ( remembering that I might
have actually posted information to this group in the past )
revealed:
http://lansdale.com/homeprod.htm
Of course, I was wrong, they were in Arizona and not Texas
( it was the desert that fooled me ). They have quite a
listing of DTL parts in the Motorola section. If anyone
does contact them for prices, could they let me know?
I see they have a minimum $1000 order.

Hi
By the way, there is a company in Texas some place that
is actually making DTL and most likely RTL as well. They
make parts for obsolete equipment. I've lost the url
but I found it with a search on the web. I was always
afraid to even ask what they were charging for the
parts ( most were mil spec as well ).

I am looking for some DTL chips to make a repro
W706/W707 TTY
interface set for my Straight-8 and PDP-8/S (got *no* serial
I/O for them. :-( )

http://www.pdp8.net/w-boards/pics/w707.shtml?small
The chips there are:
W707
MC799 Dual Power Buffer (1)
MC790 Dual J-K Flip-Flop (8)
MC724 Quad Input Gate (5)
MC789 Hex Inverter (5)
W706
MC790 Dual J-K Flip-Flop (9)
MC789 Hex Inverter (6)
MC724 Quad Input Gate (5)
MC799 Dual Power Buffer (1)
The MC7xx were RTL, not DTL. Motorola made them. They typically used a volt power supply, like the Fairchild uL9xx RTL
series of the same era
(late
'60s I think).
