In my family, my father bought the first Enterprise 128K, in May of 1989. This german version of EP.
In September I strated learning in programmer school. Few months later we bougth second EP128 for me.
Because we not have disk controller, I used the Enterprise network for software developing, I compiled the program in the first machine to NET:, and the second machine loaded it, this is many times faster than the tape

In 1991 purchased the first EXDOS card, this is one of the hungarian Exdos clones. This is
Microteam type card, contains 512K memory extension, and 3 socket for ROM extensions. The first floppy drive is Teac 5.25"/720K, few months later the second drive is NEC 3.5"/720K (but this is very special drive, can format the disk up to 90 tracks

)
In 1992 come the second EXDOS card, same type, with same Teac drive.
In this time we bought SMD Team's Turbo Cards, and make 4/6 Mhz (switchable) machines

I bought a not working machine in the EP club, and repaired it, and
extend the internal memory up to 320K.
I used this machine for developing hw tweaks, this is the
first 7.12Mhz EP in the world

after this, I tweaked the two main machines to 4/6/7.12 Mhz. The first machine memory extended to
704K (+512K on the Microteam EXDOS).
The EXDOS cards tweaked for handling HD floppy drives&disks.About the last ten years, I collected 5 other EP128
