|C=Y TM=1 BM=66 LM=2 RM=80 J=NReadme First>C=NREADME/TXT01/20/87  This is a disk that contains some mods for the LNW TEAM-MODEL 4/4P.  The model 4 mods are for the Non Green screen type. The Lnw mod has been in use for about 1 Year now and works well. The Model 4 Mod for about 8 Mo. and the 4P mod 3 Mo.  The Lnw is Different from the rest Because Both the Z80 & the HD64B180R0P is in the Machine. This Provides software compatability. I choose not to do this on the model 4 or 4P but can be done with little effort. Just follow the Lnw ExampleI will warn you that anything you do to your machine is your problem !!!!  The Team runs at 6.67 Mhz in the Z80 Mode and 6.144 Mhz in the HD64180 Mode.  There are some limitations on the Model 4/4P machines. The people at Tandy used some low grade PAL chips and there is some unessary propagation delay that causes problems at 6.0 Mhz and above. So if you have a model 4/4P the fastest you can run with the HD64180 is 5.066 Mhz.  Yes I know that you will try the faster clock ad it will apear to work fine. But when you start using the DMA controller the system controller PAL wont keep up and the system will crash..  Mods for the Lnw: LNWFIG1/TXT LNWFIG2/TXT LNWFIG3/TXT LNWFIG4/TXT LNWFIG5/TXT HDLNWMOD/TXT Mods for Model 4 MOD4HD/TXT MOD4FIG1/TXT MOD4FIG2/TXT MOD4FIG3/TXT MOD4FIG4/TXT Mods for Model 4P - Memory Mod Only MOD4PMOD/TXT MOD4PFG1/TXT MOD4PFG2/TXT Mods for Model 4P - Memory with HD64180 MOD4PHD1/TXT         ALL programs were created for use with NewDos/80 by Apparat Inc.The /asm programs were created with Zeus but are in the EDTASM format. RAMV364/ASM - RDEQV364/ASM  These two files are source code for a ramdisk that is used with NewDos/80. MULTV1/ASM - MULT3V1/ASM  These two files are source code for a Multiple operating enviroment. You can Have 4 copys of the Operating system Resident at 1 time. You switch between each copy using the F2 Key. SWAP3Z/ASM  There seems to be a number of programs that use Illegal Opcodes. now the Z80 will find the corresponding Mask equivelent and execute it. This add some NEAT register operations. However the HD64180 will Trap to Address 0.  So this program will place it self at the top of memory. This is a temporary solution that we will use until Jerry Johnson finishes the NEW Model 4/4P rom.  To use this program You Must have run SYSINTV2 to Load a Rom Image HDROM4/CIM HDEMULV2/ASM  This is for the LNW that Emulates the Illegal Opcodes SYSINTV2/ASM  This Program is for the LNW-Model4/4P  We can load a rom Image in the lower 14K ram on both machines.  To create a rom Image o the FollowingDump HDROM/CIM,0,3600H,0,8000H       ' For LNWDump HDROM4/CIM,0,3800H,0,8000H      ' For Model 4/4P  For the 4P Jerry Johnson Has a 7.5 second Boot disk for NewDos80. He wrote a Sector loader as apposed to a Byte loaer the 4P Rom uses. Also the disk can be copyed using CBF as the Modela/III is now SYS22/SYS. I will pass on any Inquires.  If anyone has some interest in the new Rom drop me a lie an I will send Info when it is done.  Jerry moved around routines and removed the unnessary stuff in order to get room for the Emulator and also the Ramdisk to Reside in the Rom , as we both hate to wast HIMEM.                                                               
