       | I bought an Apple ][e recently at an estate sale. Loved playing
       | with it and worked fine at the sale, but failed (monitor is fine
       | but main board no longer turns on, no hard drive grind on
       | startup, etc) after ~15 minutes of use. I found some
       | troubleshooting manuals and got, then replaced, a bunch of main
       | board chips. Still no luck, so I replaced the PS.
       | 
       | So I'm giving up my sunk costs on getting this actual Apple ][e
       | into working shape, but I've decided to settle for hollowing it
       | out as a sort of classic computer arcade cabinet? (with the help
       | of a apple-keyboard-connector-to-USB dongle I found online),
       | putting in a rpi4, and perhaps running an emulator to start
       | (since I'll be specifically reharnessing the original keyboard).
       | This means I'll trash the main board (and perhaps disk drive
       | enclosure, which I have no use for) and also need to find a
       | flatscreen to very safely and carefully put into the A2M2010
       | monitor enclosure after removing the CRT component (lovely green
       | phosphors, sad I won't get to see more of it).
       | 
       | Anyways, all of this is to say that this device is lovely and I
       | might get when if another piece of classic hardware falls into my
       | possession. :)

         | Spend a few hundred dollars and find someone to recap it and
         | get it going for you again.
         | 
         | An old Apple 2 is a classic machine - it shouldn't be trashed.
         | At worst sell it on to a collector for parts.

         | your hands so you don't have to mess with shipping). Apple
         | IIe's and Disk II's aren't particularly rare, but there aren't
         | ever going to be any more made.

       | It'd be really cool if a device like this tried to simulate the
       | CRTs that would be connected (blur, diffusion, persistence,
       | composite color artifacts, etc) to the vintage equipment. With
       | that, it'd be perfect to restore old equipment where the
       | irreplaceable CRT needs to be replaced.

       | 
       | There have always been adapters and multi-adapters because of
       | hand-held video recorders, various entertainment units, and even
       | overhead displays. Even HDMI comes in Standard, Dual, Mini, Micro
       | and a specialized Automotive connectors.

             | I thought that at first. But if you need to translate

             | 
             | For someone with a lot of retro gear mixed in with new gear
             | (like me), it's probably not such a bad price. Especially
             | businesses that digitize home videos etc.
             | 
             | I wonder if there is surge control on the inputs. The
             | number one reason I have to replace video adapters is the
             | input buffer frying. Ironically that often results in a
             | not-blue screen of death.
