þa‹RþwQþ m^9þhý oPþ nSystem-wide To: John Ellenby From: Bob Wulff Subject: Release of Midway "-17" boot eproms Date: November 19, 1984 cc: Carol Hankins, Dave Paulsen, Monty Boyer, Phil Ydens, Tom Hall Jack Aiello, Ken Dulaney, Paul Hammel, Larry Gravelle, Gary Brownen, Betsy Rice, Bob McFeeters, Kevin O'Neill, Dave Wurster The boot proms for Midway are now ready for manufacturing to release. If you don't care about boot proms (or don't even know what they are) you may ignore the rest of this memo. The part numbers and checksums for the Midway boot proms are: EVEN 300442-17 7BB6 ODD 300441-17 848E The proms actually have the exact same code as the boot proms for Compass II. The only difference is the prom data segment has been moved because of the larger screen. For Midway the prom data segment goes from 440h:0 to 47Fh:0, whereas on Compass II the prom data segment goes from 298h:0 to 2D7h:0. To reduce the risk for this project, we did not make any other changes to the proms. The code listings that manufacturing currently uses can be used with the new prom map. If anyone you know depends on certain part numbers or version numbers to make their software work, please have them test it on Midway.
