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
We don't found EXDOS card in the official shops
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
Now I have these serial numbers:
009007
04380
024487
019565
025525
014900
02944 (not working, possible Nick error
)
020169 (not working, many missing components
)
Other hardwares: 2
BUS extender cards,
Real Time Clock card, EPROM/SRAM extension card,
RS232 port card (for mouse),
ZX Spectrum Emulator, parallel port connected Eprom programer
And my own cards:
prototype SIMM RAM interface Prototype 512K FLASH ROM cardAnd the most important:
The IDE controller card
