Texas Instruments TI Professional Portable Luggable Computer for Parts or Repair
I cleaned the case, the compartments, and the keyboard.  I did not open the computer up to clean the inside.  I tested the unit by power it up.  The system does power up and the fan spins on the PSU.  On the front of the computer is a place for a green light to come on if functional, that green light did not illuminate.  The red lights on the two 5.25" floppy drives did not illuminate and the heads did not spin.   There was no image on the screen.  There are missing keycaps on the keyboard.  That is all the testing that was completed on the computer.
Basicaly, the TI PPC was the transportable version of the TI PC, with which it was entirely compatible.
It was one of the few transportable systems to be available with an optional built-in color monitor, back in 1983. The standard version had a classic 9'' monochrome monitor built-in.
Unfortunately the advantages of the PC Portable compared to IBM's offer was not obvious. It was not really compatible (IBM disks could be read, and that was basically all) and IBM expansion cards could not be used.
Despite this lack of real compatibility, some software were adapted to the TI Portable PC like for instance, Lotus 1-2-3 or VisiOn.
A few programming languages were available: Basic, Pascal, C-Basic, Cobol and RM-Cobol.
The graphical possibilities were quite different and significantly better than for the IBM PC, with for example, a maximum resolution is of 720 x 300 pixels. To make a IBM PC graphic program to run on a TI PC you would have to use BIOS or DOS calls.
The TI PPC had only 64k RAM that could be expanded up to 768k using quite expensive memory cards.
I am selling it as-is with no returns.
Please see photos for physical condition.
Please contact me prior to buying this item if you living in Alaska, Hawaii, or PR for exact P/H Charges.
As with all vintage items, there is no warranty.  I am selling this as-is with no returns.
eBay policies leave me with no choice but to mark each of my auctions with a “no return” policy.  This is being done to protect me against returns such as (buyer’s remorse).   After using the item for days and weeks, the buyer can submit a return and is not obligated to reimburse the seller for shipping charges and I have to pay for shipping charges back.  Even though it is marked a “no return, “a buyer can still submit a return if the item was not as described or the item was damaged during shipping.  Also, I do not need an eBay policy to do what is right and accept the item back if it wasn’t as described or damaged during shipping.  Keep in mind, that I mainly sell vintage computers and vintage computer accessories.  That said even though the box/item may not show damage, the internal mechanism may have been damaged or jarred from a rough truck and/or plane ride.  I will work with ALL my customers to resolve the problem.  Recently, I have had to take back items where the buyer didn’t check with mom/dad, husband/wife, or God prior to buying and did a return.  eBay forced me to take the item back.  Personally, I do not think that this is an acceptable way to return items.  Many of the sellers on here are just trying to provide for their families and this kind of previous return is not fair to the seller.  We are not Walmart or Costco that cannot absorb these financial damages.   Again, I will work with all my costumers to ensure that they are happy with the item they purchased.  Thank you for your patronage.
