The mystery of the jaggies solved. It's apparently due to the filter applied.

About the PDP-502R, there is a card located under the lid. The memory chip has cold solders. I have fixed a few by reflowing the NEC branded memory chip.

I'll be joining the Pioneer HM-D101 club soon -- fingers crossed the caps are not dead -- with this YAJ listing:

No remote, only tested for power, but it reached a price reasonable enough to give it a shot.



Assuming it works normally I'll do A/B tests with the MSC-4000 (2x MUSE outputs on a HLD player and 2x RGB inputs on the R2144) and keep whichever seems the best to me.

The HD-M101 is well known now but the SD-D101 NTSC down-converter listed in some MUSE sites seems impossible to locate today.

It certainly looks a cosmetically tidy example, and I would happily love to be the recipient of one of those so I’ll admit to being just a little bit envious! hope it’s in good working order for you

I'll start by removing the dust inside (the heat fan can only bring some inside and looks dusty).
And detoxit'ing the connectors that looks quite oxidized before anything else.

Won't be around to try it before Dec 2nd though.

Got it. Typo copied/pasted from site to site.

It's a Pioneer SH-D101.



Released in September 1992, the HM-D101 was released in November.
