Bit of a step forward in terms of REXCPM for T200.
In experiments on a real T200 (not virtualT), I get the following nice
result.
Question: What memory is accessed in the "address hole" from 8000-9FFF"
when Option ROM is selected (BANK3)?
- ideally CP/M needs a full 64k
- we have ram from
Henner, thanks for that measurement. That's good data.
So yeah it does seem unreasonable to pull A* around.
Seems to leave only RAMRST.
I did create a circuit that uses ALE to generate a signal "ram active"
indicating when the processor is running. It works as a ram protect ckt.
I will post
I think A* is on the system bus for exactly this purpose. /RD and /WR are
both there, so why bring out RDWR?
Other memory products used this like to disable internal ram.

Henner,
I have taken both approaches.
I have a few comments:
1) RAMRST serves to protect RAM during power events. So, I think you can
for sure use it to disable the internal ram, but then you need to take some
precautions on whatever RAM you add. I don't think it's purpose was to
disable ram
It is a timer interrupt hack to check/ redraw the date 250 times a second!
Which works fine.

If you consider saving the .DO file over serial, or loading it over serial,
it is even more tricky.
here are the cases I trap:
= 34 or =127 or <= 32
I encode the data to avoid these values If the byte matches the above
criteria, I use "/" to denote "encoded" and then I follow with the value of

I've often wondered about the purpose of the A* signal on the M100.
A* is used to control the internal RAM. It drives the timing for the RAM
chip selects. Also, since the RAM are wired with OE grounded, whenever A*
is high, the RAM will try to immediately output data, unless the processor

Is there a "best design" to use?
thanks
Steve
I've thought a few times about using that area. I never have because to
access the data requires more work and code that the system ram.
So far I've decided not to spend the code.
For Rex, that space isn't available on T200 so I've not used it on that
project.
I guess it's not a lot of code
by
adding a wire.
Which puts the T200 install on the same page as T102, with a single wire
required.

Hi
At this time, no. It would require some changes due to the unique memory
map in the T200 relative to the M100.
I think the biggest issue is that an all ram mode is not clearly possible.
There would be a hole fro. 8000 to 9FFF. That's not great for CPM.

When I have looked at the buzzer circuit circuit in the past, I was always
wondering - could you drive 2 audio signals into the buzzer?
There are 3 signals that drive the buzzer.
Port BA pin 5 - direct drive
Port BA pin 2 - on/off control for the "sound" tone
Timer signal - tone generator
It is possible to do tx and rx serial over the BCR hack.
But to do it you need to take into account the following..
1) the computer can only either send or receive at any one time. When
receiving it is 100% dedicated to the serial port. Same is true for Tx.
2) this limits the utility to

On a 27C256, I have always thought you could ignore Vpp for normal use, and
only use it for programming.
So, you could plug a 27C256 where the main rom lives in a T102 or T200, or

Hi Stehano,
I went into the file to take a look, hoping to learn a bit more about

Hi Bob,

you don't really have to install it, you just go into the folders, and run

you could set a breakpoint at the final return, and then try calling the
