The commercial life of the TI-99/4 was however short with the announcement of its replacement with the 99 / 4A which would then be presented at the "Consumer Electronics Show", on June 30, 1981.

In order not to disappoint its customers, Texas Instruments offered to replace the old computer / 4 with the new Texas Instruments TI-99 / 4A totally free of charge but on the condition that the purchase of the / 4 had been at least 6 months before. of the release of the new model, only the shipping costs were charged to the customer.

The company T.I. tried to market the Texas Instruments TI-99/4 also in Italy and France, but due to delays, its distribution was immediately interrupted to make way for the / 4A already present in the US market. In any case, in Europe the 99/4 found no interest in the market also precisely because of the monitor alley which had a US NTSC standard and therefore problematic for European standards. Texas Instruments, strangely, never officially announced the discontinuation of the TI-99/4. In total, around 25,000 units were produced.
