Hi Kevin,
I don't have technical manuals for the 150's like I do for my earlier 8-bit
Heath machines (H-8 & H-89). Perhaps another listmember has one to refer to
(Tony?). Chips were socketed on these machines so try carefully pressing
them into their sockets in case there is an intermittent connection causing
the problem. Place the board onto an antistatic bag upon a firm padded
surface which will help you do this.
What's the status of those lights (the LEDs on the CPU board)? Have an
Operating Manual? I think I recall something about interpreting the LEDs in
that book. I've got one somewhere up in the library.
I've got a big heap of 150's down in the back garage which I am planning
to: (A) Hammer together working systems and maybe sell for cheeeeep, (B)
provide parts for folks like you, or (C) scrap that which is not
desired/useable. Methinks (C) is the ultimate fate of most of the pile
nowadays, (A) is somewhat folly, butcha never know ;-)
Seems item (B) is just for you. Email me. I think there's at least 15 Z-150
boxen I've got -all from work when we moved up to 386/486 and later machines.
Regards, Chris
