Re: SCSI as a MSX link ?
I havent wathed the thread (so forgive me, if I'm a latre echo), but the SCSI-specification requires termination at the both ends of the SCSI bus. If you can have so called active termination on every device. (Passive termination is made od resistors .Active termination regulates the voltage of the bus lines) Sincerely Kari Lammassaari PS. I have noticed several times, that if SCSI-bus is not linear (ie. looks like letter Y, you must terminate each end of the SCSI-bus. Actually I an just now using this Y-shaped (plopably illegal) SCSI-bus. SCSI-bus shoulb be daisy chained and linear !

At 03:23 AM 10/11/98 +0300, you wrote: How about can I use forexample same HDD at a same time, or do I have to be sure, that it is not used that time by other computer? Unless the SCSI interfaces have a DOS2 modified for sharing harddisks (does this exist?), you will get troubles. The type of problems you'll get are very typical of parallel computing. Example: both computers want to create a file in the same directory. That process includes the writing of the file name in the directory sector. This consists of 3 actions: 1. read directory sector 2. add new filename 3. write directory sector When computer A performs these actions, I'll call when A1, A2, A3, when computer B performs them B1, B2, B3. If the two computers perform the sequence one after another, like A1; A2; A3; B1; B2; B3, there is no problem. But a sequence like A1; B1; A2; B2; A3; B3 is a problem: A1: A reads directory sector B1: B reads directory sector, which doesn't include A's file A2: A adds filename B2: B adds filename to directory which doesn't include A's file A3: A writes directory sector B3: B writes directory sector, which doesn't include A's file The result is that the file A tried to add, is erased from the directory only moments after it is written. So while some of you might think that writing a partition by only one computer is a restriction, it might actually be a safety precaution which will ensure correct writing of data to your harddisk. The sequence 1, 2, 3 is an example of what is called a "critical section". The execution of a critical section by two processes should never overlap in time. A way to fix this is to make a process (computer) lock a sector before it is allowed to modify it. This would add actions 0 and 4 to the sequence: 0. lock the directory sector 1. read directory sector 2. add new filename 3. write directory sector 4. unlock the directory sector Does anyone know whether the BERT interface has a DOS2 inside which properly addresses these concurrency problems, or whether using it with 2 harddisks is simply "hoping such bad things will never happen"?

SCSI as a MSX link ?
But if one really wants to make a network, then you should just use SCSI or so... it is developed for it, is much faster and a lot easier to use. So, can somebody tell me more about this? I have two Novaxis SCSI controllers. Is it possibble to connect both of them to different computers, put a cable between these computers and add a HDD too? If this is possibble, then do I need some special software or can I just use MSX-DOS2 and same SCSI devises in both computers ? How about can I use forexample same HDD at a same time, or do I have to be sure, that it is not used that time by other computer? Do I get a probblem, if computers use SCSI at different speeds?

If you're not using the BERT on a turboR, you can upgrade to BERT v3.0 which works faster than Novaxis. I'm not sure how the situation is right now, because work on BERT is always progressing, but last time I checked the v3.0 didn't run on turboR because of timing-problems, it was going TOO fast or something...

Approximately at the same time is good enough to get into deep troubles. And on the MSX turbo R, approximately is not even necesary because of the sector buffers of DOS2. They keep copies of the most recently used fat and directy sectors to reduce the amount of head movements necesary. Ideal scenario to get concurrency problems when both systems have write access to the same partition. Just try the next thing on your MSX turbo R: 1) Start DOS2/command2.31 2) Set the amount of sector buffers as high as possible, for example BUFFERS=18 3) Go to one of your harddrive partitions 4) Enter a directory 5) Enter the dir command 6) Turn of your harddisk and pray that your computer does not crash because of the possible powerpeaks 7) Enter the dir command again, and voila, you will see the contents of the directory again...

So, can somebody tell me more about this? I have two Novaxis SCSI controllers. Is it possibble to connect both of them to different computers, put a cable between these computers and add a HDD too? I dunno about Novaxis, but I had 2 computers and a HD connected with 2 BERT interfaces. If this is possibble, then do I need some special software or can I just use MSX-DOS2 and same SCSI devises in both computers ? You don't need any special software. How about can I use forexample same HDD at a same time, or do I have to be sure, that it is not used that time by other computer? With the BERT you can read/write to the same partition with both computers. You can't write both at the same time, because of FAT-caching. AFAIK interfaces other than BERT have restrictions, like assigning specific partitions to either of the 2 computers. So never 2 at once on one partition. Also, my experience with the BERT was that sometimes the SCSI-bus would stall. If I used a special DOS which had a hotkey to reset the SCSI-bus, I could continue, otherwise reset one of the computers. Do I get a probblem, if computers use SCSI at different speeds? (R800 3.5MHz Z80) One of my computers was running 3.58 MHz and the other 7.16Mhz, so it doesn't matter at all. I wanted to ask this, to avoid burning any of my computers or pheripherals. That probably won't happen :) Unless you got an active terminator on your HD though, you have to have BOTH computers activated on the same time. Or more correctly: both SCSI interfaces have to be on. My solution was to place one of them in a slot-expander with seperate powersupply. (The other computer was always on, it ran my BBS) I hope you succeed with you Novaxis interfaces!

Re: SCSI as a MSX link ?
I dunno about Novaxis, but I had 2 computers and a HD connected with 2 BERT interfaces. novaxis can do so too, but you have to use a unique ID for each computer.

I don't have a place for external power suply in my expander... And I'll overload the SCSI bus, if one SCSI controller is offline? Hey this is getting ugly... :-( Another possibility is to remove the terminiator resistors from the interface. your chain will look as follows: interface with terminator - harddisk or computer without terminator - hardisk with terminator You mean, that I have to open SCSI controller and take some resistors away? How about, if I do not do that for both interfaces, then I still can't use both computers independent of is another computer on or not? I mean, that only modifyed controller can be off?

How can I upgrade to v3.0 and how much money does it cost? You have to contact Hans Oranje, but I'm afraid I don't have his e-mail address. :( Someone please tell us what his address is! About the costs, you just need a EPROM replacement which AFAIK is NLG 25,-. Greetz, Patriek [EMAIL PROTECTED] ,-. ,. ,-.

Re: SCSI as a MSX link ?
:SCSID.COM. the /K option allows you to save the info in the :clockchip. WRONG! You CAN hold number 6 while booting to give BERT SCSI-ID 6 and hold key 6 to give BERT SCSI-ID 7. No, I am not wrong. May be your way is also a good one. Greetings Maico Arts MSX Mailinglist.
