Question
Prof
OK, starting to get into vector stuff and loving it.
The vector stuff so far
2 x Asteroids pcbs of ebay us (only pace to get them :D)
1 x LAI Vector chassis which suit a 14" tube or with a couple of parts changed, a 20" :) (Thanks to John JWG)
1 x Spacewar guts purchased from a Tim.
OK. First with the Spacewar.
PSU OK, Game pcb seemed to work. Monitor DOA.
First to get the monitor going. Time to scope around a bit. Seemed every transistor execpt 1 was dead in the dflection section. Also a TL081 on the x axis had no output. :(
Had a bit of fun trying to find replacements for them, but after sourcing from 2 companies overseas and 1 local, managed to get them all bar 2
Replaced all componets I had, powered up and a 1/4 of the picture!!
Finally sourced the last 2 transistors locally, poped them in and volia, full picture.
And witht the monitor workng I could now see the game pcb has problems. Seems to draw most vectors ok, but the ships are screwy.
Need to track down the fault now. But I should be able to hack it to take the asteroids signal :D.
Also, I would post a better pic if anyone can tell me how to get a good pic of vector monitors..
