ENTERPRISE 64 On top of its advanced features the Enterprise had a nice design and good quality keyboard, even if one can reproach a little 'toyish' feel for the keyboard and joystick. /media/museum/photos/enterprise_64_system_s2.jpg

ENTERPRISE 128 Little riddle: Apart from the Enterprise label, what is the only external difference between an Enterprise 64 and a 128?\ See the next picture... /media/museum/photos/enterprise_128_system_s1.jpg
title subtitle text image
BOTH MODELS So, the only difference is... the joystick cap color ;-) Green for the 64, grey for the 128. In fact there is another difference between these two models, the 128 has a German keyboard, The 64 is a UK version. /media/museum/photos/enterprise_128_systems_s1.jpg

SIDES VIEW Notice the expansion connector on the right side, intended for the (vaporware?) dual floppy drive unit, and the ROM cartridge slot on the left side. /media/museum/photos/enterprise_64_sides_s1.jpg
title subtitle text image
CLOSE-UP The joystick replaces arrow keys in the Basic editor and wordprossor, it seems to be a bit fragile for action games though. /media/museum/photos/enterprise_64_closeup_s1.jpg

REAR CONNECTORS **(1)** Reset switch\ **(2-3)** Joystick connectors\ **(4)** printer connector\ **(5)** Serial or network connector\ **(6)** Jacks allowing to connect up to 2 tape recorders\ **(7)** RGB output connector\ **(8)** TV aerial jack\ **(9)** External AC adaptor jack. /media/museum/photos/enterprise_64_rearcon_s1.jpg
title subtitle text image
64'S MAINBOARD The delay in the Enterprise launch was primarily due to design difficulties with the two custom circuits which provide the Entreprise with powerful graphic and sound features. The general design of the unit is of good quality. **(1)** First custom IC, called Nick, from its designer's name. Controls the powerful graphic features. A rudimentary heat sink covers it\ **(2)** Second custom IC, called Dave. Manages 4 sound channels and 8 octaves.\ **(3)** Expansions port, mainly intended to connect the (vaporware ?) double floppy drive unit\ **(4)** 32 KB ROM chip. Holds the Wordprocessor program\ **(5)** Z80-A microprocessor running at 4 Mhz, here a SGS version\ **(6)** 64 Kb. RAM, stored in eigth 4164 chips (64000 cells x 1 bit)\ **(7)** Keyboard connectors. Notice also the smal loudspeaker, fortunately, an Hi-Fi sound output connector is provided\ **(8)** ROM cartridge connector, mainly used by the Basic language cartridge.\ **(9)** Power regulators heat sink. /media/museum/photos/enterprise_64_mainboard_s2.jpg
title subtitle text image
128'S MAINBOARD The mainboard is exactly the same as the 64 version, a piggy-back 64 KB RAM expansion card has simply been added. /media/museum/photos/enterprise_128_mainboard_s1.jpg

The Enterprise 64 was a very long-awaited computer, two years between its announcement and its marketing! It changed its name a lot of times: its first name was Elan 64, then Flan, lastly Enterprise.

It has great features, which wasn't found on all other home computers, like its interfaces, great graphics and sounds capacities provided by two special custom chips called "Nick" and "Dave".

The BASIC Interpreter is supplied on a ROM cartridge and can be easily replaced with any other language. This BASIC is a very powerful structured basic with great graphic commands and can store several programs simultaneously in RAM.

It has a small word processing in ROM and up to 32 computers can be linked together.

But despite its great characteristics and all its interfaces, the Enterprise 64 was a flop in the marketplace.

Several months later, a new model was launched: the Enterprise 128, which was nothing more than an Enterprise 64 with 128 KB RAM.
Unsold stocks of these systems (nearly all :-)), were sold to East-Europeans countries, and especially Hungary where it met great success. Thus, most nowadays Enterprise activity comes from here.


Kjetil T. Homme specifies:
The editing of the word processors was exploited during programming -- you could scroll up and down and edit the code with ease. You could hold down shift while moving the joystick to move by whole pages and quickly scan through the code. Contemporary computers required you to write LIST 100-200 so it fit on the current screen, and then you could move your cursor to edit those lines. The comparative ease of editing made the line numbers in BASIC much less of a hassle, which contributed to its higher level feel compared to other BASIC dialects.
EXDOS was the DOS which was in the ROM of the floppy disc adapter. It was sort of CP/M compatible, so you could run classics like WordStar and SuperCalc. It was surprisingly modern and used FAT12 as the filesystem, so I could easily transport files between my Enterprise and my Atari ST. I could even use the same DS/DD Cumana floppy drive, since it used a standard Shugart interface (the ST needed a converter cable to a DIN plug).
The RS432 serial interface could in theory handle greater speeds than RS232 (with which it is backwards compatible).

Andrew J King reports:
The Enterprise case was designed by UK product designer Geoff Hollington, subsequently more famous for his work for Herman Miller office furniture.
