Hi there,
You have one of the older Development Jaguars. What this means is that it contains the debugger stub(ROM), if its blue its the '93 ROM not the '9$ and therefore cannot use Flash Carts.
You can't use this to develop on the Jag without at least some additional Hardware.
A. The hardware intended to be used with that kind of development Jaguar is the Alpine Card. B&C, BEST and maybe even 16/32 may still have versions of this. This was a car which simulated being a rom cartridge, whilst the debugger stub inside the Development Jag allows the memory/registers of the Jag to be communicated to the development computer. They tend to be expensive however. The cable from the Jaguar is used to connect to the Alpine STOP connector so that the alpine can stop the jaguar and allow interogation of memory and registers, one-step execution, etc.
Programs are uploaded to the card from the parallel port and can be loaded into Cartridge ROM space or machine RAM.
Lars Hannig at www.atari-jaguar64.de has some of the development tools for download and a CD full of the development docs, code and tools for ST/TT/Falcon and PC (DOS) and Linux.
I personally use the Falcon as i find it most stable, but most people are coding on a PC.
B. BJL would be a good method of developing too, but cannot simulate the ROM cartridge. This would also not take advantage of the debugging capabilities of the Development Jag that you have. Programs are then downloaded into the Jag RAM via a cable connected between your PC parallel port and the port 2 joystick port on the Jag.
BJL requires either a new ROM to be soldered into your jaguar or a copy of Protector SE from Songbird (NB Protector doesn't seem to work with my DevJag)
C. JUGS
Similar to BJL but less common as it requires you to gave a copy of Battlesphere Gold (instead of Protector SE), which I'm sure is a fantastic game, but which for many people is prohibitively expensive.
Jag CDs are NOT cheap. They are rather too scarce and anything below about £100 is not bad.
If you need any clarification on any of this, I'll be glad to help.
Cheers,
AtariOwl
