Technobytes, known for their new hardware for classic computers like our beloved MSX system, has put up a pre-order page for their upcoming slot expander. As the Slot Expander project is expensive to be produced, they need a minimum quantity of sales to be viable.

Price: US$ 139,00. Shipment Prediction: February / March 2017.

  • 4 Expanded slots that can fit even large cartridges
  • 60cm buffered flat cable
  • Exclusive plastic cabinet (in development)
  • 5V External power supply (included)
  • You can easily disable a slot (you don't have to remove the cartridge). Each slot has one key and one information LED
  • "DC IN" Status LED: The main board and the cartridges are protected against incorrect voltage (low or high), any problem with the power supply, even if you forgot to connect one. The DC IN Status Led will blink in any of these cases;
  • High quality board

Check the Technobytes pre-order page

Update 16 December 2017: The slot expanders are currently in testing phase, and Technobytes is currently expecting everything to be shipped before Christmas.

It's worth mentioning that this slot expander is a reproduction of the famous NEOS EX-4, which is sought after for it's excellent quality and long data cable. The per-slot LEDs and disable switches were a nice addition by Tecnobytes.

The final product will have a plastic case made by QuickPlast, the same company that made the cases of the Zemmix-BR computers. Tecnobytes said that they'll soon publish some 3D previews of the case so people can have an idea of how the finished product will look.

BTW, they hope to have a plastic case soon, in order to protect all components.

For the shipping you have to add 30$ more.
It is quite expensive, but worth it !!

Are you sure? Because the product page states "Paypal fees & Shipping not included".

And, if you consider that the original EX-4 was priced at ¥29,800 some 30 years ago, and this one costs ¥16,264, maybe it doesn't sound that expensive.

Is it designed to work only at 3.58Mhz? Or can it also handle higher speeds?

If you want to order it then order it. If everybody is waiting for the goal to be reached before ordering the goal will never be reached. I just ordered mine.

A question, just how does this work? Of course, you can insert multiple modules, but are those true additional slots? Or do you have to select which slot the MSX will see as the "active" one? Suppose I have an FM PAC in one, and a MEGAFLASHROM in another, I think I will have to select one to be active before powering on, correct? There will be no "run-time" switching? Like, I start a demo that will use FM PAC from the MEGAFLASHROM and then quickly switch to the FM PAC. Just making sure I understand before ordering. Smile

Yes, I have also ordered somewhere in March, and ... nothing, it's indeed long, maybe it takes time to do it, I'm ready to accept to receive the components and assemble it myself if it needs (I'm not joking).
I'm so desperate by this that, I'm currently investigating how to build a slot extender myself in order to make coexisting opl4 + v9990 (pure IO accesses).

I got mine. See it here:

Works like a charm and looks even prettier than I expected. I'm quite fond of the little details, like connectors both in front and in the back of the expander, with eject tabs for the flat cable. The slot openings have a good wiggle room for bigger cartridges and the expander itself is very sturdy. Please have in mind that international S&H can take a while. Also, Brazilian mail services were at strike recently.

I bought MSX products made by Tecnobytes and I can tell you that no other MSX manufacturer gave me as good service as Tecnobytes. Their product are really good and they always deliver what they sell. You will receive your slot expander and I'm sure you will be satisfied with it.
