- HARDWARE
-
- CD-Joy is a small PCB (printed circuit board) that plugs into one of
- the CDTV I/O chip sockets on the motherboard, the displaced chip then
- plugging into a socket on CD-Joy. The PCB is about 2 inches square, and has
- a 20-way ribbon cable coming off the side which splits into two 9-way
- ribbons with a standard joystick socket on each, where port 1 is the ribbon
- with the coloured edge. It's an elegant system, as it needs no extra chips
- or components on its board.
-
-
- DOCUMENTATION AND INSTALLATION
-
- The A5 instruction sheet contains assembly details as well as
- installation instructions and diagrams. Originally, GoldTech sold the things
- in kit form as well as pre-assembled, but stopped this after user problems
- during assembly. *NOTE*: due to the design, installation VOIDS THE CDTV
- WARRANTY, so you MUST be reasonably comfortable with "Hacking by the seat of
- your motherboard" tactics.
-
- Installation is straightforward enough. Removal of the CDTV top
- panel is a game of 4 side screws, 2 back screws and a couple of metal tabs
- that lock under the front panel. There's no RF shielding in the way -- the
- motherboard is well-designed and easy to get at, with only one flying lead
- across the board <From the PSU> and all I/O interfaces on ribbon cables that
- plug in at the edges of the board.
-
- The instructions make no mention of static grounding, although I
- earthed myself beforehand anyway. From then on, it's a case of
-
- <1> removing the CSG 252609-02 (lovely memorable name) chip at the
- very front of the motherboard,
-
- <2> plugging it into CD-Joy's board (aligning the chip and socket
- notches as usual),
-
- <3> plugging the CD-Joy board into the empty motherboard socket (it
- will only fit one way - the CDTV case sees to that), and
-
- <4> trailing the 9-way ribbons across to the backplane of the machine
- and hanging 'em over the back edge.
-
- My only complaints with the fitting are the usual ones. Every socket
- extender I've seen uses circular pins. Chip sockets are designed for flat
- pins. Wooooo. You've got to use some force to get the board in, but you
- mustn't bend the pins either. The chip was pretty stiff to get out, too, and
- a proper chip extraction/insertion tool is a must. Gripe off.
-
- Because the CDTV is well packed into the box, you can't get the lid
- back on unless the CD-Joy board is pushed fully home into place. I recommend
- you leave the lid off until you've tested the interface. When you reassemble,
- the 9-way ribbons won't get cut on the backplane, although I keep the lid a
- little loose just for the cables' safety.
-
-
- CD-JOY IN ACTION ('Back to work. Boot Lotus and fire up Angel Dust...')
-
- Games used for testing: Lotus Turbo Challenge II, Llamatron
- (Robotron 2048 clone on Fish 560) and DragonCave (SokoBan clone on Fish 395
- -- may have been withdrawn from the Library) amongst others.
-
- According to the operating instructions, you can plug in 2 joysticks,
- or a joystick and mouse. To activate, you press RIGHT on the CDTV remote
- control once the CDTV is switched on with program loaded. I've never had to
- do this - the ports seem to work from power-up anyway.
-
- Effectively, the widget gives you the normal Amiga joystick ports
- OVERLAID onto the action of the CDTV mouse and remote control. In test, the
- joysticks (Zipstick Super Pro and Cheetah Mach 1+) worked normally, port 1
- being combined with the CDTV mouse, port 2 being overlaid onto the IR remote.
-
- Of course, you can use the 'sticks or mouse normally, but if you've
- got a sick and twisted mind and really want to try to confuse the system...
-
- In DragonCave, the mouse can be used for selecting icons and the port
- 1 'stick fire button for confirming, whilst the port 2 'stick or IR remote
- works the fallback movement system. (Download the game and play it, if this
- isn't too clear.)
-
- With Lotus 2 in two-player mode (one 'stick on each knee... sad or
- what?), player 1 can have the port 2 'stick for control, with button A on
- the IR remote for accelerate, and for player 2, the port 1 'stick in
- combination with accelerate on the left mouse button.
-
- There was a dodgy period when the port 2 socket played up with
- constant RIGHT signal, but that was quicky cured by opening the socket up and
- pressing the 9-way ribbon cable firmly onto the connection. (It's a
- press-fit, and it just got a bit loose. I've not had any problems with it
- since.)
-
- Because of the way CD-Joy works, you can leave the joysticks or mice
- plugged in if you wish to use the CDTV's nice-but-nonstandard wired mouse.
- According to Ralph at Goldtech, more than one mouse online through CD-Joy may
- confuse the widget, but I've yet to give it a try. (Anyone for 2-up Lemmings
- on CD?)
-
-
- OTHER COMPARABLE PRODUCTS (Or 'Take the money! Open the Box!')
-
- Another way to get round the joystick problem is via the Brickette,
- which retails for around 50 pounds, and sits on the mouse port on the back
- of the CDTV. It's constructed more robustly, is intelligent (read: has its
- own chip for signal processing), and costs twice as much. It acts like a
- normal pair of Amiga ports, so you can't leave both sticks plugged in and
- use the mouse at the same time. And you don't lose your warranty. The
- choice is yours. High cost, retained warranty, or low cost, high
- performance.
-
- And finally, there's the CDTV IR Trackball, which, as well as the
- trackball, has 'stick ports and genlock control and plugs into the mouse
- port. But it costs around 75 pounds. Again, your choice.
-
-
- CONCLUSION
-
- Pricewise, it's a great bit of kit, although the CDTV should have had
- proper joystick ports as standard anyway. Being able to leave everything
- plugged in is a boon, and reduces the chance of blowing CIA chips if swapping
- devices when powered up. The joystick sockets could be a little stronger re
- the ribbon cable fixing, but you can make your own holes and mount them in
- the CDTV box if needed -- they've got screwholes on each side, and Ralph at
- Goldtech said he'd done such modifications for a couple of customers.
-
- Since my first CDTV review, it seems that Goldtech and Almathera were
- designing joystick dongles simultaneously, and it was Ralph's unit that went
- into production. The best dongle won? A lesson for us all, methinks.

- DISCLAIMER
-
- THP is not connected to Goldtech apart from being a paying,
- harassing customer, listens to Faith No More a lot, and is only vaguely
- connected with the real world. So no surprises there. Oh, sod this, I'm
- off for another crack at level 85 on Llamatron....
