Macintosh SE Superdrive (1.44) ROM flash service

[lem150]

Hi I am looking for someone to create the three ROM chips (hi, low, swim) so that my Macintosh SE can use a 1.44 superdrive floppy. I can pay for the chips or buy them, although I have no idea where to get them from?

The SWIM isn't a ROM chip, it's an integrated logic chip, so I'm afraid you're stuck looking for an original of that one.

I see! I thought you could flash them with a flash tool?

The ROMs you can, but the SWIM isn't a ROM.

Google AI has failed me again! Do you have one to sell me?!

"AI" doesn't care about Facts.

You can get a SWIM that will work in your SE from Kero's Mac Mods in Japan for $48: https://en.infinityproducts.co.jp/product-page/super-wh-iwm-swapper-plcc44-to-dip28-swim-adapter

For an extra $16, you can also get flashed ROMs, but they're not pin-compatible, so there's a little extra work required to install them.

It's probably better/cheaper/easier just to find an FDHD SE logic board.

For reference, here's a picture of an SE FDHD logic board (from oldcrap.org)

When searching for an FDHD logic board be sure the SWIM/IWM chip matches up with this photo
