Welcom here!
I just bought an Enterprise 64 from a seller who seems to have several boxed computers which he's selling as new. Obligatory photo included ![Smiley :)](/Smileys/phpbb/smiley.gif)
Can I ask another one with the Serial Number? For the
big EP statistics.Does anyone happen to know if Enterprises were ever shipped without BASIC?
No. But easy to lost it under ~35 years...
Anyway I often see standalone cartridges at same Egyptian seller...
1) you can also load machine code programs from the WP, don't need a BASIC for playing most of games.
2) best way to get BASIC: upgrade the onboard ROM to EXOS 2.4, which have a built in. One 27C512 EPROM needed, and solder
one wire for the A15 address line.
This is ROM upgrade also highly recommended, because many of programs compatible only with EXOS 2.1+ but the EP64 just come with earlier 2.0
and am attempting to control my patience so I can see if the Enterprise is working ok?
You can also try it without display. Power on, wait few secs (memory test), then need to hears key click from the internal speaker when pressing keys. If this is done, then machine mostly working.
I'm also hoping to buy an SDcard adaptor from Szorg.
It is also including the BASIC in the default ROM pack. Then not need to look about cartidge, even if not upgrading the onboard ROM.
If do the ROM upgrade, then you can have free 32K RAM space in the SD cartridge, you can install other utility or programing languages.
I'm not sure how I got hold of it or if it works
For a first look I recommend replace the Philips electrolytic capacitors. The C9 are the most critical. If it is dried out then kill the TR2 transistor in the internal 12V circuit, then the video circuits don't get the 12V supply.
It is also possible this is happened with that board many years ago.
Later boards with a non Philips capacitors less problematic.
Another common failure (at unknow dead boards) when the machine tried with a wrong polarity PSU. Then the board look total dead, power LED still remain off. For a repair need to replace the two 7805, TR2 (BC337), and LM386 (amplifier for internal speaker, directly connected to the 9V). It is can be repaired less than 10 minutes
