Some mechanical issues we had to sort out first:
* Top & Bottom Teflon Lead Screw Missing, We found used ones in storage (lucky)
* # 6, #10 Cap screw missing, Mr J. bought some at HD and replaced
* Lead Screw shaft coupler missing, Found this one at Amazon and ordered it

Electrical Issues:
* Broken Limit Switch, We bent back into place, but it need to be replaced
* Spindle motor disconnected, We Reconnected back
* Missing ROM Memory Chips
ROM IC
Both High and Low EPROMS were missing, we found Ver 5.0 on the web. The EPROMs are 27C1001, 1 Meg 128K x 8, Speed is 70nS. To erase the PROMs we used a UV led pointed into the PROM window for 10 minutes, this cleared it for programming.
Here are the HEX files V5.0
HIGH ROM - Is located in IC12 (Marked with H)
LOW ROM - Is located in IC13 (Marked with L)

CPU
Inside the AMC2500 sits a very powerful Freescale MC68332ACFC16. The MC68332, a highly-integrated 32-bit microcontroller, combines high-performance data manipulation capabilities with powerful peripheral subsystems, Data sheet in link below
