838-PEB

[shift838]

I have designed a new PEB for the TI-99/4A and Geneve 9640 computers.

I have made a video explaining what is on the new 838-PEB as well as a short demonstration of it working.

It's almost 28 minutes long between both videos that I combined.

I have posted it on my YouTube channel link below.

Wow Chris, it looks like you thought of everything on that new board.  I especially like how you thought of TIPI placement and it's power requirement.  Will the board come with all the necessary cables and power on controller?

[shift838]

All cables would be included.  the power on controller will be an option to purchase as some users may just want to add a new power switch or swap out the existing momentary switch that is on the current PC case.

Introducing the new 838-PEB Board from SHIFT838!

Pre-orders will start very soon! Keep an eye out here and on AtariAge for when the pre-orders open and close.

This board allows the user to replace their aging Peripheral Expansion Box with a PC style ATX case and ATX power supply which provides a more stable power supply along with much quieter.

Works with your existing cards.

This board comes with features to include external Gotek expansions, pass through power, internal PC fan connectors (4 x 12v), voltage breakouts for 3.3v, 5v and 12v! USB passthrough and standby power. Use of front USB ports for supply powering to USB devices or use with new MicroGoteks to USB storage media for the Gotek drives! 838-Latching Relay module to allow current PC momentary power switch to act as a latching switch. Press to power on, press again to power off!

Check the two videos out below for more information.

I wanted to post about the new 838-IO Plus vs 838-IO Plus ATX versions for use with the 838-PEB.

I have redesigned the 838-IO Plus card that needs to be used with the 838-PEB.

The ATX version is a bit shorter to allow for the cable to snake into the IO Port hole in the back of the PC case and plug directly onto the card without causing uneeded stress.  With the 3 Mid tower cases I have, none of them would allow this with the standard 838-IO Plus card for the TI PEB as it was too long and put the cable in too much of a bind.  So the ATX version was born.

If you are planning to purchase a 838-PEB and will be using a  mid tower case then you will need the 838-IO Plus ATX version of the PEB card.  it will work with the sideport 838-IO Plus card as it has the same pinout requirements.  If you id not purchase the origin 838--IO Plus card at all but plan on getting the 838-PEB then you will need the 8380-IO Plus ATX and the sideport version along with a cable to go between the two cards so the 99/4A and the 838-PEB card can communicate.

You can see the difference of the PEB cards in the attached photos as the ATX version is more than 2 1/2 inches shorter.

This is a real cool project to be sure, sadly I've invested too much time, energy and money in my current P-Box system to switch over.

the Preorder closed and all boards and components have been ordered.  I should see the boards in 2 - 3 weeks.
