Setting up the Horizon Ramdisk

2016-08-29T03:29:20Z

Chris Schneider:

The Horizon Ramdisk 4000 can be emulated within MESS/MAME 16MiB of SRAM! The data that is stored on the RAM Disk is actually saved in the '''"\nvram\ti99_4a"''' directory within a file.

'''Note: The directory is usually classified by the current machine type being emulated'''

The emulation will respond to the equivalent speed of the ram disk on actual hardware.

This process was created using MAME0176b 64bit and ROS version 8.32e.

'''Note: If using ROS 8.14f or earlier, sector sizes will be limited to 1600. ROS 8.32 and higher allows for 3200 sectors per disk.'''

== Procedure: ==
 
1> Boot into ''MAME'' and the ''TI-99/4A ROM'' 
2> Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
3> Configure your '''System Devices''' for your wanted configuration. For this example I will be showing PEB Slot #5 as the Horizon RAMDISK.

4. '''Reset''' the machine for the settings to go into effect.
The default CRU address for the ramdisk is 1200. If there will be multiple HRD's then the CRU address will need to be changed for each additional HRD to a CRU that does not conflict with any other expansion card. 

5. Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
6. Select '''Machine Configuration''' to configure RAMDISK installed RAM.

[[File:HRD2.jpg]]

 
9. Select the '''Horizon''' ram disk slot 
10. Select '''Horizon CRU base''' option and change the CRU appropriately 
[[File:hrd3.jpg]]
 

You will need to do this for each ramdisk within the system if you have more than one. 

11. '''Reset''' the machine for the settings to go into effect. 
12. Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
13. Select '''File Manager''' to select cartridge and disk images.

19. Press '''2''' to go into Extended Basic and the ''HRD ROS'' Loader should load. 

[[File:hrd6.jpg]]

 
20. Select '''1''' for ''CONFIG Loader/Editor'' 

The ROS CONFIG will detect the currently installed expansion cards. The below image shows two Horizon Ramdisks. 
'''Note: The larger the RAMDISK card size the longer it will take to detect the cards.''' 

[[File:hrd7.jpg]]

 
21. Press '''ANY KEY''' to start configuration 
22. Press '''L''' to load configuration file 
'''Note: If using ROS 8.32 or earlier then select the appropriate configuration file for the disk controller installed into the system (Myarc/TI/CorComp). ROS 8.34 has the configuration for all floppy controllers built into one file.''' 

[[File:hrd10.jpg]]

 
23. Press '''E''' to edit configuration 
24. Keep all defaults but change '''Power Up''' to '''N''' ''(NO)'' 
To cycle through selections press '''ENTER'''; '''FCTN-9''' when done (ALT+9 in ''MAME'') 
[[File:hrd8.jpg]]
 
25. Press '''D''' to configure RAMDISK drive assignments and sizes 

'''Note: Use cusor keys to move different disk drive numbers''' 
26. Select Disk Drive # to assign 
27. Assign a Disk Name of the disk (based on TI Disk Naming criteria) 
28. Select N for No Write Protection 
29. Select Y to format the drive 
30. Select sector size 
'''Note: 1600 max sector size for ROS versions earlier than 8.32 3200 sectors size for version 8.32+''' Drives can be denfined from '''DSK1-DSK9''' and '''DSKA-DSKZ''' 
[[File:hrd9.jpg]]
 
31. Press '''FCTN-9''' when done (ALT+9 in ''MAME'') 

[[File:hrd8.jpg]]
 
If there is more than one Horizon Ram Disk installed then hit '''N''' for next to configure the next HRD. 
'''Note: The ROS does not verify selected Disk Drive numbers/letters that are already in use. The user will need to keep track of what is in use.''' 

'''Now the HRD should be accessible.'''

Chris Schneider:

[[Image:mess_logo_n.png|150px|right]]
MESS (Multiple Emulator Super System) is a multi-system emulator which emulates more than 400 computer systems, many of them from the good old days of the Home Computers. Among them are also a number of TI platforms:

* TI-99/2 (not working)
* TI-99/4, 50 Hz and 60 Hz
* TI-99/4A, 50 Hz and 60 Hz
* TI-99/4QI, 50 Hz and 60 Hz
* TI-99/8
* Geneve 9640

A number of peripherals are also emulated, ranging from various disk controllers (up to HFDC), to serial interfaces, USB interface, IDE interface, HSGPL, and also SGCPU.

Since version 0.162, '''MESS is an integral part of MAME''', the Multi-Arcade Machine Emulator.

The emulator is currently available as [http://www.mamedev.org/release.html version 0.172] pre-built for Windows systems, and as a source zip archive for all platforms.

You can download and work on the MAME source codes, since all MAME components have been relicenced under an open-source licence (BSD or GPL). If you want to contribute, you should get in contact with the maintainers, though. A good location for that is the [http://forums.bannister.org/ubbthreads.php?ubb=postlist&Board=1&page=1 MESS message board].

I would be happy to see more people from the TI community helping to improve the TI emulation in MESS.

Setting up the Horizon Ramdisk

2016-08-28T22:50:42Z

Chris Schneider:

The Horizon Ramdisk 4000 can be emulated within MESS/MAME. This selection will emulate a two MEGABYTE ramdisk which is actually saved in the '''"\nvram\ti99_4a"''' directory within a file.

'''Note: The directory is usually classified by the current machine type being emulated'''

The emulation will respond to the equivalent speed of the ram disk on actual hardware.

This process was created using MAME1076b 64bit and ROS version 8.32e.

'''Note: If using ROS 8.14f or earlier, sector sizes will be limited to 1600. ROS 8.32 allows for 3200 sectors per disk.'''

== Procedure: ==
 
1> Boot into ''MAME'' and the ''TI-99/4A ROM'' 
2> Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
3> Configure your '''System Devices''' for your wanted configuration. For this example I will be showing PEB Slot #5 as the Horizon RAMDISK.

[[File:1.jpg]]

4. '''Reset''' the machine for the settings to go into effect.
The default CRU address for the ramdisk is 1200. If there will be multiple HRD's then the CRU address will need to be changed for each additional HRD to a CRU that does not conflict with any other expansion card.

The Horizon Ramdisk 4000 can be emulated via MESS/MAME. This selection will emulate a two megabyte ramdisk which is actually saved in the '''"\nvram\ti99_4a"''' directory within a file.

'''Note: The directory is usually classified by the current machine type being emulated'''

The emulation will respond to the equivalent speed of the ram disk on actual hardware.

This process was created using MAME1076b 64bit and ROS version 8.32e.

'''Note: If using ROS 8.14f or earlier, sector sizes will be limited to 1600. ROS 8.32 allows for 3200 sectors per disk.'''

== Procedure: ==
 
1> Boot into ''MAME'' and the ''TI-99/4A ROM'' 
2> Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
3> Configure your '''System Devices''' for your wanted configuration. For this example I will be showing PEB Slot #5 as the Horizon RAMDISK.

4. '''Reset''' the machine for the settings to go into effect.
The default CRU address for the ramdisk is 1200. If there will be multiple HRD's then the CRU address will need to be changed for each additional HRD to a CRU that does not conflict with any other expansion card. 

5. Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
6. Select '''Dip Switches'''

7. Select the '''Horizon''' ram disk slot 
8. Select '''Horizon CRU base''' option and change the CRU appropriately 
[[File:hrd3.jpg]]
 

You will need to do this for each ramdisk within the system if you have more than one. 

9. '''Reset''' the machine for the settings to go into effect. 
10. Bring up the ''MAME'' menu by pressing '''SCROLL LOCK''' then press '''TAB''' 
11. Select '''File Manager''' to select cartridge and disk images.
12. Mount the ROS disk image

13. Select '''Cartridge''' to load ''Extended Basic'' 

[[File:hrd5.jpg]]
 
14. Press '''ESCAPE''' twice to exit the ''MAME'' menu 
15. Press '''SCROLL LOCK''' to disable the ''MAME'' menu 
16. Press '''ANY KEY''' to go to ''TI-99/4A'' menu 
17. Press '''2''' to go into Extended Basic and the ''HRD ROS'' Loader should load. 

[[File:hrd6.jpg]]

 
18. Select '''1''' for ''CONFIG Loader/Editor'' 

The ROS CONFIG will detect the currently installed expansion cards. The below image shows two Horizon Ramdisks.

19. Press '''ANY KEY''' to start configuration 
20. Press '''L''' to load configuration file 
'''Note: Select appropriate configuration file for the disk controller installed into the system (Myarc/TI/CorComp)''' 
[[File:hrd10.jpg]]

 
21. Press '''E''' to edit configuration 
22. Keep all defaults but change '''Power Up''' to '''N''' ''(NO)'' 
To cycle through selections press '''ENTER'''; '''FCTN-9''' when done (ALT+9 in ''MAME'') 
[[File:hrd8.jpg]]
 
23. Press '''D''' to configure ram disk assignments and sizes 

'''Note: Use cusor keys to move different disk drive numbers''' 
24. Select Disk Drive # to assign 
25. Assign a Disk Name of the disk (based on TI Disk Naming criteria) 
26. Select N for No Write Protection 
27. Select Y to format the drive 
28. Select sector size 
'''Note: 1600 max sector size for ROS versions earlier than 8.32 3200 sectors size for version 8.32+''' Drives can be denfined from DSK1-DSK9 and DSKA to DSKZ 
[[File:hrd9.jpg]]
 
29. Press '''FCTN-9''' when done (ALT+9 in ''MAME'') 

[[File:hrd8.jpg]]
 
If there is more than one Horizon Ram Disk installed then hit '''N''' for next to configure the next HRD. 
'''Note: The ROS does not verify selected Disk Drive numbers/letters are already in use. The user will need to keep track of what is in use.''' 

'''Now the HRD should be accessible.'''
