The design of this late TI-30 SLR+ is slightly different from the original version. Note the added TI-logo and the missing stripes left from the AC/ON-key and seems to be identical with a TI-30 SLR+ introduced in 1989. We added it just for curiosity, according to the date code it was manufactured in 2000!

In more than 10 years of production we recognized in the meantime four different designs of the TI-30 SLR+:
