Is there someone who makes MSX HW today that could produce a new batch of 8x slot expanders, with cable and external power plug?

I know that I can put 2 of supersoniqs expanders together but, these are out of stock and not available now.

AFAIK Sunrise and L.Padial did make 8 slot expanders in the past. Did anyone else??

Anyway, who still carries a stock of 4x expanders today (Reprofactory has sold out as I see)?

Sunrise expander?

Do you know that 8x slot expanders have only 4 real slot and 4 I/O slot ?

Reprofactory's new 4x expanders will be available in january.

Yes I know Smile. Since you write 'new' expanders, are we talking about different model or restock of the 'old' one?

What influence did lack of above had on the previous version? Just curious. I have the old one, but I'm not too technical with slot expanders.

No problem with the old one.
These signals management is useless for me.
If someone thinks different he can explain why.

/INT- Without /INT cartridges which generate interrupts (example: MSX Audio, Moonsound) won't work properly and the programs using them may crash.

/WAIT- Without the wait signal cartridges can't inject wait states on the computer, to slow the computer down on special cases. May cause crashes or malfunction of the cartridges connected without this signal.

BUSDIR- Matters if you connect the expander to a computer with buffer on slot. No BUSDIR, MSX computer cannot read input from I/O ports on the cartridges connected to it.
