You email the company? Looks good.

The HXC floppy replacement looks good also.

Maybe the Frostbox Labs guy might figure this out. He fixed the clock problem. Smart guy.

I once had a large box of brand new drives paired with new interface boards from SSL. I ended up making about 25 cases to house them. I still have a few if anyone wants new.

Wow Frank. Love this forum. Next thing you'll tell us you have extra TR computers 8)

What else do you have?

Funny thing is, I do. I also have most of the SSL computer pcb's in cad ready for layout. I wanted to remake the TR computer using CPLD's and bring it down to one new pcb instead of 5.

- 2mb memory board is finished - just have to optimize it.
- 4100C is finished as well, but I wanted to swap the memory on board out for a single newer chip solution. Use CPLD's to drop the size down and use the extra space for the 2meg card. Also add in the bus card since there is next to nothing to it.

I get into these crazy projects, then get distracted and forget about them. Those drives have been on the shelf since 2014.

I know there isn't much demand for these things, but it's fun.

If only it were this easy for SSL floppy replacement.

Saw this video today and thought Frank might know.

These floppy replacement units come in many flavors from USB to SD readers....Frank if you can get these to work in those SSL floppy units you have I'll buy one.

EDIT:

Also what about this unit?
