ENTERPRISE Code-Book (and Part-List for foreign versions):
The code book is very interesting, because it shows all parts and suppliers of ENETREPRISE Computers UK. It is very accurate and shows the state of June 1986. The handwritten things were done by myself. Unfortunately there is no original version anymore and my printout has faded, but everything is readable.
 
The Part-List for foreign version is also very interesting, because it shows only one foreign computer (Model 408, EC 128k German). ENTERPRISE UK has never produced other specific versions apart from 64k/128k UK English and 128k German. There were some model-variations with/without manual, with/without cassette, with German power plug, with European power plug, ...) but no other keyboards or system-extensions like :BRD. The company in Cairo made the keyboard printing by themselves and the cyrillic computers we've made simply got transparent stickers on the keytops.

Space for the keyboard connection cables to "curl up" when the top is on?

now the details about the MIDI-cartridge:
 
When Vimos Kopacsy was in Munich in autumn 1989 he presented me a MIDI-catridge for the ENTERPRISE. The cartridge was longer than a standard EC cartridge and contained an eprom, an EF6850P async I/O chip, some Ics and two MIDI-connectors for MIDI out/through. The software was far away from being ready, but the cartridge was already able to play some midi-files. He brought a Roland MT-32 digital sequenzer to show communication and the result was impressive.
 
He told us, that they would develop a software with a full graphical user-interface and promised that within 1990. A few months later I visited Budapest and he presented me the cartridge with a software package called "ScoreTrack 1.0". It looked complete, and ready for use, but he told me, that the software would still have some stability problems, which they were working on. He gave me a sample cartridge, incl. the software.
 
The software reads and writes *.SND, *.MID, and *.ENV files, but unfortunately not compatible to the common standards. To show the file-format I have added the file "OKTAVE.MID". The copyright in the files and in the software says "ENTERPRISE Computers Ltd. EED". EED stands for "East European Division". This was a joke, because it should have been "VTGe Electronics Ltd.", which was a joint venture between us and aStudio.
 
A little bit later he told me, that all development on this cartridge/software has been stopped, because there would be no market for it in Hungary or anywhere else. Instead of this they were working now on equipment for the ATARI ST series.

And now something very special!
