M: I have an old Samsung scd103 video camera. I’m trying to find a new memory stick for it. Unfortunately, the easy answer – do a search online – is being made difficult because it uses the old “memory stick” flash card, so any search for the item has at best come up with every other kind of flash card that has been developed since then and had words like “pro“ and “duo“ appended to it, not to mention that it seems every USB drive is now also referred to as a memory stick… Can you help me refine my search in a way that Amazon and Google will be able to distinguish from every other dam memory device available on the market?

G: TL;DR: Search for "Sony Memory Stick (not PRO, not Duo) 128MB -legacy original format" and use -pro -duo -micro in search terms to filter out newer types. eBay may work better than Amazon for this legacy item.

The original Sony Memory Stick (used by your Samsung SCD103) predates the Memory Stick PRO, PRO Duo, and all the other offshoots. Unfortunately, modern search engines now treat "memory stick" as a synonym for any flash drive.

Search tips:

To zero in on the correct product, try this search query on Google or eBay:

"sony memory stick" -pro -duo -micro -m2 -usb site:ebay.com

Or on Amazon:

"sony memory stick" -pro -duo -micro -usb site:amazon.com

Add terms like 128MB or original to improve chances.

Specific identifiers you want:

Look for Sony Memory Stick (non-PRO), model numbers like MSA-128A.
Sizes were typically 4MB, 8MB, 16MB, 32MB, 64MB, 128MB max.
It's longer and thicker than later Duo versions (31mm wide, 50mm long).

Alternative sources:

eBay and AliExpress are your best bet. The item is obsolete and out of production.
Try retro forums or camera collector groups; some users sell or trade them.

G: Short answer: No, the MSAC-M2 adapter won't work in your Samsung SCD103.

Why:

MSAC-M2 is designed to adapt Memory Stick Duo or Memory Stick PRO Duo to full-size Memory Stick slots.
Your camera, the Samsung SCD103, only supports the original Memory Stick format — not Duo, not PRO, and definitely not high-speed variants.
Even though the adapter fits physically, the camera likely won't recognize PRO or Duo cards, because:
- They use a different file system structure.
- Larger capacities (over 128MB) and faster transfer modes are not backward-compatible.
- Many older devices have firmware limitations and will reject or malfunction with PRO/Duo cards even via adapter.

What will work:

A genuine original Memory Stick (non-PRO, non-Duo), max 128MB.
Model example: Sony MSA-128A.

You cannot reliably use:

MSAC-M2 adapter with any PRO/Duo/Micro card.
Anything over 128MB, even if it’s a full-sized stick, due to the camera's firmware.
