DIY SIO Hub - Is there anything I'm missing?

[NISMOPC]

I plan to build a 3 connector SIO hub using an old Axiom AT-846 case (and parts).

 

Is it as simple as just running all pins in parallel or is there more to it?

 

Seems simple enough and feel it should just be a pass-thru with no extra connectors or parts.

do it just like you see in the back of an Atari disk drives pcb.....

Have you seen Best Electronics' Apelink? It's available in kit form.

 

Take note that some plastic cutting is required if you wish to use the 3rd SIO port and if you wish to have 3 available ports you must supply your own SIO half cable. Otherwise all the parts required are included in the full kit and yes, just straight thru wiring to each port. Just solder the SIO jacks and the SIO half cable.

 

I bought 3 of these long ago but have so far only assembled one and not quite for the purpose intended. I hacked in a barebones (no buttons, no LEDs) SDrive which left room for only two available SIO ports.

Yes I'm aware of that kit. Not too fond of the triangular layout. I already have all the SIO parts and the AT-846 case seems to be a perfect unit in size and use.

[a8isa1]

Fair enough. I'm looking forward to seeing your completed project.

 

When you have the extra SIO ports you'll wonder how you ever managed without them.

[NISMOPC]

Getting parts together. Removed female SIO and SIO cable from board to re-use. Goal is two SIO ports on backside and one SIO cable on front.

Might add SIO2PC/SIO2150 internally. Plenty of room.

Hello NISMOPC

 

If you have a extra SIO connector, I'd leave the SIO cable as is. Since they are all just connected together, it doesn't matter which SIO connector you use to connect your device to the computer. Devices without cables hanging from them are easier to store, plus you can use the SIO cable you're not cutting in half for other purposes.

 

Sincerely

Food for thought. Thanks!

some more food for thought is putting all the connections on the back, its a lot easier to manage cables when they all point the same direction

Reason I contemplating one front connection was to run directly from computer to splitter, then peripherals connected to the back, but still in build phase and haven't hacked up the case yet.

another option in a split shell is run one from the side, take a hacksaw to cut the up and down parts, then score the sideways parts with a utility knife, pair of pliers should snap it off extremely clean (tidy up with a file or light scrapes from the knife edge)

that is an axiom at-846 parallel adapter..... wow sorry to see it hacked to bits.... oh well, that was a decent adapter.... they made nice serial converters at one time too...

I attempted to sell it on several occasions, but there was no interest. Came in a lot I purchased a while ago. So I decided to make use of it.
