Description
Congratulations on your purchase of the new 838-PEB board.
This board allows a user to be able to build their own 838-PEB to be used with the TI-99/4
and TI-99/4A home computers as well as the Myarc Geneve 9640.
The 838-PEB board has a standard Micro-ATX board footprint with all mounting holes so
that it can be placed directly into a ATX PC case and is designed to be used with a standard
24 pin ATX power supply.
Disclaimer
This unit has been thoroughly tested with many original and 3rd part
peripheral expansion cards for the TI-99/4A and Geneve 9640 computers.
By purchasing the 838-PEB board the consumer agrees that SHIFT838
(Chris Schneider) is not responsible for any damage to your system,
cause of fire or any issue resulting in injury, death or dismemberment!
Many of the original TI and 3
rd
party expansion boards may need to replace their voltage
regulators. I recommend at minimum a 1.5-amp voltage regulator as they will run a bit
cooler and with the newer regulators, they are more efficient.
Be aware that the ATX power supply will deliver 12v to the 8v line of the original expansion
cards and the voltage regulators will take over to reduce the voltage to the 5v required.
For all 12v required boards, the 12v will be delivered to the +12v and -12v line.
