MonSTer , neue Karte von Alan ...
Burkhard Mankel:
Naja - beim Atari müßten aber mAn 3-4 Geräte vollauf genügen dürfen - große HDD (wobei ich für mich ausrechnete, daß eine kleinere einstellige GB Größe ausreichend sein müßte um genügend Festplattenplatz zu haben, den man unter TOS ohne Hilfsprogs verwalten kann) - nämlich 1-2xHDD (oder Equivalent), 1xCD/DVD und evtl 1xWechsel-Datenträger zum Datentausch, wobei ich auch noch nicht weiß wie ich einen solchen zB am Atari Hotplug-fähig bekomme!
Lukas Frank:
Die SD oder auch CF auf IDE Adapter die ich habe an meinem Mega ST sind alle nicht "Hot Plug" fähig ...
Lukas Frank:
Meine Karte kam heute morgen aus England ...
Mal schauen wann ich Lust habe die einzubauen, da die Positionen der IDE Anschlüsse anders sitzen muss ich alles umbauen.
neogain:
Schick. Bin mal gespannt auf dein Review. Sind die baden TSOP's Flashchips für das Tos? oder ist das der Alt-Ram?
Lukas Frank:
Frage mich mal ...
- ganz links S29AL016 irgendwas (zu klein, kann ich trotz Lupe und Brille nicht lesen)
- mitte R1MV6416RSA
- rechts Xilinx XC9572XL CPLD

--- Code: ---The MonSTer board by Alan Hourihane (c) 2015
============================================
After many months of producing the IDE boards, it was time to move up
a gear to a CPLD and stop soldering the many TTL level logic IC's.
Additionally the seperate 8MB RAM module put additional strain on the system by
stacking more boards.
It was time for a new board.... The MonSTer was born.
The name came from the fact, it's small, but contains a lot of goodness.
Also, because it has ST in the name, the "M" too, and for the Megas, but
even better that it's "STe" in the name for all the ST, STe, MegaST and
MegaSTe machines.... Hoorah !
One thing was still missing though........... Flashable TOS.
So, I've added it.
But things don't stop there.
You can also attach an RTC module to the board too, that's if you need it.
If you have a MegaST or MegaSTE these machines already have RTC's so you
don't need this additional item, but for STE and STFM's it's great to have
an RTC.
The RTC module I have tested and produced the software for is the Dallas
DS1338. They are available all over the web. Find one that has 3.3V operation
and has the SCL/SDA lines and you are good to go.
The Xilinx XC9572XL CPLD is the heart of the system glueing everything
together, the Flash chip, 8MB RAM, and the IDE controller. But it also
controls the JBLOCK. The JBLOCK is both a jumper block and where the RTC
attaches to. See below for the pin information...
3.3V 3.3V 3.3V 3.3V 3.3V 3.3V
TOSSEL FLASHSW FLASHON IDESW SCL SDA
GND GND GND GND GND GND
TDI TMS TCK TDO GND 3.3V
PRIMARY LED SECONDARY LED ACSI ACSI
RTC connections - DS1338 module
-------------------------------
Connect your RTC voltage pin to the MonSTer 3.3V line (above SCL/SDA).
Connect your RTC ground pin to the MonSTer GND line (below SCL/SDA).
Connect your RTC SDA pin to the MonSTer SDA pin.
Connect your RTC SCL pin to the MonSTer SCL pin.
Jumper settings
---------------
TOSSEL - When set to GND, the system boots from 0xE00000 i.e. TOS 2.xx
When set to 3.3V, the system boots from 0xFC0000 i.e. TOS 1.xx
NOTE: It's even possible to boot an STE with TOS 1.04 :-)
FLASHSW - The MonSTer has a 2MB Flash chip, and only 1MB of the chip is
mapped for the system to boot at 0xE00000 or 0xFC0000.
This switch flips the second 1MB into the 0xE00000 or 0xFC0000
window, so you can flash the second part of the chip for
swapping boot images.
When set to GND it enables the first 1MB.
When set to 3.3V it enables the second 1MB.
FLASHON - This disables access to 0xE00000/0xFC0000. For recovery mode.
If you ever run into problems, you can install the original
ROMs and re-run the flash program which will write to the configured
1MB region to get this going again. Use the FLASHSW to select
regions.
When set to GND the FLASH is enabled.
When set to 3.3V the FLASH is disabled.
IDESW - This flips the primary and secondary IDE ports.
When set to GND the primary/secondary ports are as labelled.
When set to 3.3V the ports are reversed.
SDA/SCL - For connection of the RTC module.
PRIMARY LED - This is a two pin header for attachment of a drive activity LED.
SECONDARY LED - As above for the secondary port.
ACSI/ACSI - Two pins for attachment of the interrupt cable, and another for
daisy chained hardware (if required).
TDO/TMS/TCK/TDI/3.3V/GND - these are the JTAG pins for the Xilinx programmer.
512K EmuTOS
-----------
This works too.
Flash Disk
----------
Future possibility....
The MonSTer has 2MB of Flash, and there's potential space in the flash area
for a fast boot disk or upgraded TOS, like the 512K EmuTOS images. But even
with 512K EmuTOS there's space for other things, such as the flash disk.
There is no software currently to take advantage of this extra space, but
watch this space......
Software
--------
There are some supplied programs for the MonSTer, and kudos to "joska" aka
Jo Even Skarstein who has helped write the software.
M_FLASH.ZIP - The MonSTer flash program to write to the onboard flash.
M_ALTRAM.ZIP - Alt-Ram program for 2MB, 4MB, 6MB or even 8MB of Alt-RAM.
M_RTC.ZIP - The Dallas RTC clock module
Flashing
--------
Basically you can have four TOS versions installed. Two 192KB versions
and two 256KB versions.
Example...
TOS 2.06 (TOSSEL set to GND, FLASHSW set to GND - first MB)
EMUTOS 0.9.4 (TOSSEL set to GND, FLASHSW set to 3.3V - second MB)
TOS 1.04 (TOSSEL set to 3.3V, FLASHSW set to GND - first MB)
KAOS TOS 1.04 (TOSSEL set to 3.3V, FLASHSW set to 3.3V - second MB)
Please see http://emutos.sourceforge.net for more details.
Comments

I hope you enjoy using the MonSTer. And please let me have any feedback
on how you use yours !
Alan.
