Hey, I've got one of those somewhere (the delay line, not the terminal ;-) )!
I do still use the cabinet as a desk, as well as a few parts here and there; to think that today something like an Arduino nano can replace that desk-sized cabinet containing a substantial power supply and a card cage with at least a dozen cards IIRC... I'm still amazed by how far we've come in less than my lifetime... m On Fri, Apr 1, 2022 at 2:30 PM Chuck Guzis via cctalk <[email protected]> wrote: > On 4/1/22 10:27, Paul Koning wrote: > > > > > >> On Apr 1, 2022, at 1:25 PM, Chuck Guzis via cctalk < > [email protected]> wrote: > >> > >> Wasn't some of this glass delay line memory used in early raster-scanned > >> computer video displays? > > > > I don't know about that one, but a delay line is a key component of a > PAL (European) system color TV receiver. > > I know that the CRT display controller on the CDC 200 series terminal > (INTERCOM, Export/Import 200 software) used a 10 msec magnetostrictive > delay line.for image storage.
