Now I'm a happy owner of 4 "SVI-709 MSX Network Interface Card".

According to this page http://www.faq.msxnet.org/hardware.html#Spectravideo :

"This cartridge transforms your computer into a station in the SVI-609 Local Area Network. These stations are given access to the mass-storage and rapid printing resources of the SVI-609 Master Station. Each slave station can make use of a portion of the SVI-609's 10M-bytes hard disk for its own file storage, and all stations can share a common storage area, printer spooler and software library."

So... Do I really need the "SVI-609 Master Station" to connect some MSXs?
Is there a manual available on web?

Finally I had some time to dump the SVI-709. The dump was done with the MegaFlashROM, the SVI-709 inserted in slot2 and SAVEROM with parameters "Normal" and address interval 0000-FFFF.
Strangely I found these texts:
MSX-DOS ver. 2.2 Copyright 1984 by Microsoft ... Disk-BASIC version 1.0 ... AUTOEXECBAS RUN"AUTOEXEC.BAS" and other stuff
I cannot understand if these texts come from pieces of MFR firmware, or maybe these DOS is a spin-off of the official MSX-DOS releases. Will try on a MSX1 without diskdrive to investigate if Disk-Basic comes from the SVI-709 alone.

That is some old and very rare piece of hardware I guess! Evil

Indeed... I have one of these as well and you are right... This cartridge includes a version of Disk ROM to use the hard drive and other functions like printer from the server.... The server was not done on MSX, but on SVI-328. There was special version of SVI-605B super expander that had two extra cartridges. (I guess that is the SVI-609) The actual server software was on ROM of RS-422 card (using Z8530) that was connected to the SVI-709 clients on the ring network. AFAIK there was also separate card with WD1002-SHD to actually boot from ST-212 HDD, but it did not contain any software. It may be that some part of the functionality was running on top of CP/M operating system.

Unfortunately I've not seen or heard that any of these server devices would have survived to this day and AFAIK these cartridges are useless without the server, so I bet you have quite a useless card in your hands... and no, I've not seen manual either.

Thankyou Nyyrikki for the additional infos. A friend of mine owns the SVI Expander and SVI-328. I don't know if this expander is a special version for the MSX network, but worth meet him to try...

There is always that 1% change, but I'm not holding my breath. Smile

A I can see, there's room for expansions and upgrade of the cart.

The SVI-709's wiki page claims that connectors are 10BASE-T, but they are RJ11 see here:
