On PEBs and power, I have the necessary data to do a 3- or 4-slot mini-PEB based on one that the Hunter Valley User Group did. The board is pretty straightforward and already has the flex-cable logic on it, so it would be another way to get expansion possibilities in user hands. I haven't looked at what they were using as a power supply yet (or the little board they put on the TI end of the expansion cable). It uses standard PEB cards too.

 

On cards that send audio to the console, there are several: The CorComp Triple Tech, The Berlin Speech Card (from Winfried Winkler, about 20 of these were made), the SNUG SPVMC, The Rave Speech Adapter, Marc's SID Master, the TI FORTI card, and the TI Video Controller. Greg's Speech Adapter will soon be on that list as well. I have all of these boards except for the Video Controller and the Triple Tech.

If you design an intelligent system with cashing and such, then why have a PEB at all?

 

First, because a bolt-on side-car expansion is likely not going to emulate every possible card a user could want or have.  Secondly, because it's there.

I recognize the SID Master as needing a better codec.  The speech cards should be handled by something like AMR (though even MP3 looks doable,) but anything which generates "real" sound will need better than a codec designed for speech (AMR only codes up to the 3400Hz area, IIRC.)

Actually, thinking about it, the FORTI card sends its sound out the back of the card to give 4-channel stereo sound. . .I'm not sure it uses the Audio line to the Console at all. I'll have to do some experimentation on that one.

I'm also nearly finished with a layout to set up a "Y" for the external bus. It has the utility of rotating the foot for the regular PEB cable 90 degrees to make that a little less of a hassle. The second connection is still to the side, but it should be OK for folks wanting to put something else there. It was a way-station to the finger-board with 44-pin connector layout, so I'll be able to finish that one really quickly too. . .which would make this board work well as an extender and/or a splitter.

Do I understand that it would take the place of a P-Box Y-cable?

You have any pictures?

Not yet--I just started on the layout this morning. It is basically a rectangular PCB with one set of connector fingers towards the back of the console, a connector that mates with the 44-pin console connector fingers, and another set of connector fingers that is on the far right side of the rectangle (opposite the TI connector).

 

And Atrax, it does indeed replace the "Y" cable. I made sure it was spaced out so that two PEB cables could easily connect to it, if needed.

 Now this is more like it!  Best post I've seen all week!

 I'm a bit paranoid about supplying the all the card data they require though, especially after all the hacking and identity theft I've read about lately.  PayPal makes life easier for the shopper as the company your are purchasing from never gets your personal financial data, thus limiting your personal exposure.   I've never used one of those 'throw-away' pre-loaded jobs before, but this just might be the ticket for this purchase.

 

And a third price with the same SKU.

Any further developments to the ideas brought up in this thread? My simple but unobtainium extender cable continues to work. The TIethernet concpt was very intriguing. Could multiple consoles access one PEB in a network? Or even cross-platform?

That is/was my plan, to make the protocol point-to-point or switchable and addressable.  The problem as noted by a few others, however, is that the protocol will not only push, but could even exceed, the limits of gigabit.

 

Maybe I could with 4gigabit fiber, instead ;)

Many years ago someone showed me at the West Fest a project of a SCSI cable with Snap on ends like a RS232 Printer clips.

 

He had a modified Interface Cable Card and the end was a Speech Synthisizer that plugged in to the TI. 

(Cable could be removed at both ends.)

 

 

It had a bunch of switches on it too. (It looked longer then the normal cable but less bulky to use.)

Since I recently posted this question anew, I figured I may as well dredge up the original post I made in 2014. Did anyone ever take their conceptual ideas further? There were some interesting ideas, some of them foreshadowing today's expansion options.

 

A lot of discussion was generated by my innocent little post. Fast forward to today, with more options on the table to make our imaginations a reality, is this worth revisiting?

 

Meanwhile, my ol' low-buck original still works as good as when new some 30-odd years ago. I don't set up my TI and PEB without it!
