Testing Adapter for sram 62256 in SOP28 (flat pins)

[TheDeath]

I literally cannot find a proper adapter, it's driving me crazy.
All my programmers can test srams but i can't find a socket adapter for 62256 srams in SOP28 package.
All i was able to find was a sop28 adapter for "curved" pins/inner bent and nothing else for the flat version of them, used in many stuff, most likely neo geo mvs.

Do any of you have ad adapter that fits these?? Where i can find one?

I had the same issue and ended up buying the proper ZIF socket and wiring the adapter myself.
I can send pics tomorrow so as the socket ref.

P.S.: the "curved" pins are called J leads

Thanks, i appreciate I was worry to be ended up like that, now i'm pretty sure about it haha.. let us see your creation then!
PS: i think i might have finally found it https://it.aliexpress.com/item/1346454981.html?spm=a2g0s.9042311.0.0.139a4c4d4ItWgB

If that's 300mil you're after.
I remember I already had a SOP28 or 32 adapter but for a different package size.

I've used a SOP32 socket, ref. OTS-32-1.27-05 (ENPLAS).

(Yes I know I've inserted the chip backwards in the 3rd pic )

Nice, thank you!
Is it 1:1 pin ratio? From what i recall the pinout is the same exact as the DIP package. So then the socket actually do exist I think the one posted from aliexpress will do since it's the same part number, i'll buy one and if does not work i'll rewire that bastard

 

[Apocalypse]

Yes 1:1 pinout.

The one from alieexpress is dirt cheap, but when I did search for such adapter I couldn't find one at that time.

[EDIT]
That's 450mil I was after, not 300mil.

Apocaypse one is more useful because can handle to 32 pins , but what comes from China belong other this kind adapters as present with my Top3000 , looks like the same in the aliexpress link . Hope i will need it to use it sometimes

That one won't work for the RAM chips we're targetting, width is too small.

[EDIT]
Just checked and I also have this adapter, which is 300mil thus can't be used for the RAM chips discussed above.
It's probably the reason why I ended up building one of my own.
It's 450mil you need.

I have found this one but holy crap is it expensive!!
