Spirit Technology Inboard 1000 w/ Amiga 1000 Daughterboard and PALS - PARTS ONLY
This is a Spirit Technology Inboard 1000 memory expansion for the Commodore Amiga 1000. This item is not working correctly and should be assumed as parts only. The included daughter board does appear to work when used in a stock Amiga 1000 alone, but when the expansion board is installed as well, it only turns on to a red screen. The A1000 daughterboard has the sockets that were instal...led at some point in the past along with the PALs for the Inboard (and grounding modifications). The memory board has two clips which attach to the daughterboard and there is a 68000 CPU installed as well as well as fully populated DIP sockets. One of the CPU extension pins is bent slightly but can be easily straightened. There are some marks around the solder points for the sockets, I don't know if that has anything to do with why its not working but please see pictures for details. This needs someone who knows what they are doing to go through it all or could be used as parts.
