It's an interesting time warp we
wtile columns in. As I w rite these
words, the Blizzard of '93 has just liniShed
ravaging the East Coast This
"storm of !he century" diSnJpled many
plans, including a family affair we had
been planning lor several years. Our
event has been rescheduled lor June,
just as this column will be published .
Strange but true? YOIJ be the Judge!
Anyway, thai aside, here is a little
note from Tom Vicinanza WA2UCH of
oaerco. Florida , sent over the CompYServe
network. Tom states thai he
read, with Interest. my February 1993
column o n getting an old Model 28
Teletype mactine ba(;l( on ~ne. He has
a Model 28-KSR about whiCh he has
some questions. Tom has a loop sup.
ply. made lor the US Navy. whiCh delivers
20 mA al 130 VOC. This loop
supply appears to be an lntel'face , and
is labeled a "rete'rermrnat." At any
rate, his p roblems are wh ere to putme
current and where to connect the signal
line. The machine has a polar relay,
so the wiring will be different lrom
that pubUhed In Itle Feoruary colurlYl.
He believes that il the current Is appIiecllo
terminal C5 (Black +) and C15
(Red -I that should be correct. but he
doesnl see where to put the Incoming
signal from a decoder. Still C1 and
C2? He asks how he can gel his machine
to run local. postulating that he
couk! provide a closed loop to create
the "sitting idle" eneci. men connect
the loop 10 the outputs 0 1 the 1eleTetmlnal
(or similar de'lic8) to print data.
