Rex = no ram. just backups of whatever is in ram to a nvram storage
I have ram chips in stock.. so you can expand to 32k..

the QUAD used to be available that replaced internal ram but it's no longer
being made

Re: [M100] question regarding floppy disks.

the controller and fat probably are not.. they were designed before that

Re: [M100] question regarding floppy disks.

[Gregory McGill]

likely the floppy controller doesn't support 80 tracks or high density..
most of the controllers of the era are ds/sd 40 track or dsdd 40 track..
 are you able to format 720k? ds/dd 80 track?

Re: [M100] Greetings to the M100 community.

[Gregory McGill]

Welcome Tim!

I recommend using mcomm on an android device such as the android tv boxes I
sell pre-configured with all the cables needed. Also there is mcomm for
windows, laddiealpha for dos/linux/mac and others..if you need something
portable a cell phone with android will work as well with an OTG cable and
the same cable setups for the rs232 and null modem.

Re: [M100] REX in a sub-standard machine

[Gregory McGill]

bucket = 24k
flash image = 32k

you can't put 32k in 24k so it will truncate at 24k..  or saving flash
images from that machine will only save 24k of data. because that's all
there is

easy fix: I sell 8k ram at arcadeshopper.com

to totally cold boot the 100 to get it to work if you have used any other
rom software or bank system with it.. Try that!

Also there are two dead keys x and l both are in different scan rows so I'm
thinking it is the switches themselves I can't seem to test the switches
with a continuity tester and hesitate to try to yank the key caps off until
I confirm they actually come off

I have not looked at the M200 schematic but I’m assuming it uses the
Hitachi type LCD drivers like the M100/102 does. I seem to recall these
take a command word, like to set the ‘cursor’/write position and then the
data to write. Since half of the screen is working properly the data lines
are getting there OK as are any shared chip select and R/W signals. Any
chip select from the main board that is unique to each driver would be
suspect as well as any traces/logic on the LCD board to the affected areas.



I’m not sure that helps, it will be a case of tracking down signals I’m
afraid.

[Gregory McGill]

Yes well make an offer worked out this time. And I didn't pay 125 for
either of them. An offer is better than "you can fix it" to these sellers
as if they could fix it they would have already. They are pricing these way
too high for not working and no box etc.. letting them know what they are
really worth will help other sellers see reality. Then there's always the
hold outs there's a recycle place in town trying to get 175 for a broken
386.. sigh

Yep me too, but I did set up a firewall on the BBS that blocks the 'bad
countries' that most of the attacks come from..
port 23 open is way too exciting to the morons..

Re: [M100] List of capacitors

[Gregory McGill]

woops wrong group he posted in my other group:

A while back we did a server upgrade, and the new FTP server tool we use
requires a non-encrypted FTP (no SSL or TLS) connection with the user name
'anonymous' and no password (not even your email). That is the only way
anonymous FTP works any more. If you use a browser and go to
ftp://ftp.whtech.com, you can use 'anonymous' as the user, with no password
as well.


Alternatively we set up an http/https connection too...
http://ftp.whtech.com and https://ftp.whtech.com . Both of which mirror the
FTP just like you were connecting via FTP.


The new FTP server was in response to the constant barrages of bots trying
to break into the server via insecure known FTP exploits. Not that they
could have done any damage since everything from the public site is
read-only, it was quite annoying. Sometimes we'd see 20-30,000 failed
logins a day with all sorts of dictionary attacks. Now, if any IP fails
logging in 5 times it's banned.


Hope this helps for everyone!!

yep and as I stated in a post in this group it is because the haxxors are
