RS's collection of IC's was always very strange. Simple TTL, a little CMOS
and then some high-integration devices like the 76477. Same for discretes.
Part of getting old is not remembering things.
Today I was looking for something (A Cipher 525 tape drive) that I bought
NOS years ago and left in its original box. I thought I'd found it, opened
the box and discovered a Sinclair ZX80 with the "A Course in BASIC
Programming" book. The problem is that I don't remember getting this
thing--I'm sure I didn't buy it. Maybe Dave McGlone tossed it in when we
were swapping junk years ago. (P.S. I did find the Cipher and discovered
that I bought two of them).
I don't know if it works, since I don't know the polarity of the 9vdc
adapter. Either way, is this just common trash or is this actually worth
something?. My wife suggested that I throw it out; she figures that if I
didn't even know that I had it after all these years, that I certainly
don't need it now.
Cheers,
Chuck
