This was the first computer I used as a kid. It most certainly ran standard PC software, although it didn't take standard ISA adapter cards, just like the PCjr.

When we got this computer, it ran DOS 2.11, which made the 3.5" drives "pretend" to be 360kB drives. We later upgraded to DOS 3.21, which supported 720kB disks. It also supported an external 10MB hard disk. It was binary compatible with all manner of DOS software as was common during that day, such as Flight Simulator II, IBM PASCAL compiler, etc.

The article states that it only accessed the first 40 tracks. Did it really use only the 40 tracks or did it double-step and use only the odd tracks on 80 track drives? --Matthiaspaul (talk) 23:09, 16 August 2012 (UTC)[reply]

The JX was my first ever computer. In 1984, it was well known that Flight Simulator was the standard test for PC compatibility. So I made certain that this machine could run FS before I bought it. The article is wrong on that point. It definitely ran FS. —Preceding unsigned comment added by 220.253.93.113 (talk) 11:59, 17 March 2011 (UTC)[reply]
