1) What's the specification of the MSX slot connector (both straight and "right angle" models)?
2) Where can I buy those connectors?
I have a friend with a Hotbit with damaged slot connectors. Both the upper and side slots are in a quite bad condition and need to be replaced. As I compared, both the Hotbit's slots are identical to the MSX Turbo-R slots: both include the flanges, one slot is straight and the other is "right angle".
What you're looking for is called a "card edge" connector, 2 x 25 contacts, in 2.54 mm (0.1 inch) pitch (=regular). And you want it with contacts meant for soldering to a circuit board (through hole). Although the 2 x 25 pin version is hard to find, I've still seen them in several online shops recently (like here). But mostly they're not for soldering, but for connecting to a flatcable (floppy/HDD style), so watch out for that!
I'd try some Google searches with varying search terms, and check lots of results to find a shop (that delivers) in your area.
Good look with finding an angled version of that oO - consider ripping one from another, broken down machine. Also it's possible to use a longer one, saw off a piece, and block/solder together the contacts right next to the last ones to be used. Ugly, only recommended as last resort.
Btw. are you sure it's the connectors themselves that are damaged, and not the connector <-> circuit board solder points?
Thanks for the tips!
I'm sure the slots are damaged. Many pins are bent or missing. Pretty sad.
