Forsale, lot of 3 NOT working Asteroids PCBs. Sold as a group. Asking $210 $135 USA ONLY. Paypal only. PP Friends and Family get FREE shipping, else pay actual shipping. Will discount Asteroids Multigame kit if ordered at same time (very limited qty left).

For all 3 boards, the 4 ROMS have been verified as correct in my eprom programmer and labelled. See pictures and notes on individual boards. I tried to test these boards multiple ways, mostly using the Asteroids Multigame as it has much better diags and isolation features than regular Atari test mode. I've had these boards for many years in storage. Not my area of expertise for repairing them, will leave that for the experts.

Ast-6 No CLOCK, so nothing runs. No video. Loud audio hum.
Ast-7 No Audio (or faint), No video. Using AST Multi diagnostics mode got some life and LED codes (6-p1, 1-p2) which indicates fault in the Vector Engine Go/Halt/Go test. Ast Multi completes the power on selftest with an error, but since no video can't see what the error code is. Without the AST Multi kit, game continually watchdogs. Missing coin counter Transistors.
Ast-9 No video. Testmode 4 high beeps, 2 low beeps, would normally indicate bad Vector Ram. The Rams are in sockets and I moved them around and still get the same codes so does not follow the chips.

Sold AS-IS, no returns, no refunds. I'm selling off all my remaining boards.

PM me with any questions.
