ZX Interface 2 problem

[ScottC2010]

Hi,
When i plug a joystick into an interface 2 the number 3 comes up over and over again: 333333333333333.... If i push the joystick to the right it stops - any ideas on this problem?
Kind regards
Scott

This indicates a problem with your joystick’s wiring—either it’s the wrong type, or it’s faulty. The Interface II takes the standard (Atari) joysticks. The SJS-1 joysticks (used in the Spectrum +2 and later models) are incompatible with the IF2. They’ll have to be rewired in the following manner:

Code: Select all

Pin 1	Up
Pin 2	Down
Pin 3	Left
Pin 4	Right

Pin 6	Fire

Pin 8	Ground

The so called Sinclair joystick did not see the light of day until after Amstrad bought Sinclair. It is wired so it works in the non-standard joystick ports on the later Amstrad manufactured models.

The Interface 2 was designed and sold by Sinclair long before the Amstrad take-over, and as pointed out in the post above, uses standard "Atari" standard digital joysticks. Yes, Sinclair used a normal standard connector

Thanks for the extra info mark - it is rather odd of Sinclair
Joystick now working so that is good - i got the interface at a radio rally along with a microdrive, tape player some games and a mk1 speccy with the rubber keys (Just no board inside but keyboard ok - all for 50 pence so a good bargain
I have a plus3 as wekk as the 48k+ - along with other comps such as the atari 800xl and amiga 1200 and a couple of megadrives etc
