The Starlet comes with a number of programs that run from ROM. MicrPro’s Wordstar and CalcStar are included in their mobile, “To Go” forms. WordStar was the de-facto word processor back in the day and so it’s inclusion here is logical. In addition, there is a terminal emulator and personal filer.
The terminal emulator is worth a special mention. It emulates the DEC VT-100 terminal. This is one of the most popular terminals and being emulate one allows the Starlet to communicate with most available systems of the time. In addition to emulation, Telecom offers file transfers both as plain text or with modem7/xmodem protocol. There is even a switch on the file that allows it to convert WordStar files on the fly as they are being transferred. This must have been quite a boon at the time.
The Starlet had a variety of add-ons available there was a 3.5″ floppy disk drive, a CRT/disk adapter, a 32K RAM cartridge. I don’t have any of these so can’t really comment but they look to be well thought out.
