The M18 Mark IV

The ABS designed and built Mk IV.  (What I wouldn't give for a Mark IV with a Hawk Disk!)

The Mk 4 has the same processor as was developed for the 6ME

(The CPU datasheet for the Mk IV says it will support up to 128K words of core.  I think that is very unlikely as the backplane wouldn't support that many core memory boards, and there was no support for bank switching.  'Marketing speak' I reckon!)
