[M100] batteries...

[Gregory McGill]

so I decided to take apart my m100 that has 8k of ram to see what's in
there and what I find is acid it looks like it may have not left the
battery just yet so snipped that thing out of there and cleaned up with
some vinegar etc..

need the battery source now :)  also is there a ram module source since we
can't get quads?

yeah I threw it on cloudt to try it :)

 Ahh, that's how you are emulating the 2.4MHz speed.  I was wondering.
 What do you use to determine the number of cycles to dynamically delay?

Well it’s basically on cpu cycles per instruction. There are definitely
some inaccuracies beyond just the JavaScript event driven model (I don’t
get to be the only code on my thread or get a guaranteed time slice).  But
it ought to be close enough.

The JUMP game seems to work off how fast inkey$ runs. I am guessing the
issue is that CloudT does some queueing beyond what the model t provides
due to some very fancy keyboard stuff going on in mobile browsers
(predictive text and such). So keys batch up and allow the man run faster
than he should.

Ahh, that's how you are emulating the 2.4MHz speed.  I was wondering.  
What do you use to determine the number of cycles to dynamically delay?


VirtualT works a bit differently.  It has two threads running:

1  Thread T (throttle) wakes up every 20ms (10ms for Windows) and 
calculates the number of emulated CPU cycles the emulation thread is 
allowed to execute.  This number will vary dynamically depending on the 
number of FLTK window updates during the previous 20/10ms period.  It 
then wakes up thread E and goes to sleep.


2.  Thread E (emulate) wakes up and executes the number of allowed CPU 
cycles for this timer period as calculated by Thread T then goes back to 
sleep.  So the throttled emulation (2.4MHz, 8Mhz, 20Mhz) modes actually 
execute 8085 code in short bursts every 10/20ms.

Ah. Well, CloudT dynamically inserts delays to simulate the Model T
processor speed. If you look at the number at the bottom of the screen it
should over around 2.4Mhz. But being written in Javascript and running off
timer event callbacks, I can't get cycle accuracy.

It may actually have nothing to do with cpu cycles but instead keyboard
emulation.

That was my original plan but when I was testing in in CloudT the timing
was way off.  The code increments a counter while looping for key presses
to determine how fast you are running so it's pretty sensitive to differing
clock speeds. I tuned it on my real Model 102 and VirtualT locked to 2.4MHz
gives similar results but CloudT was running either too fast or too slow, I
can't remember which now.

You could try it like this

Browse Chrome or Safari to

Open another tab to

https://github.com/ksbex/basic-longjump/raw/master/JUMP.BA

This should download the JUMP.BA file

In the CloudT tab, select Choose File

Navigate to your Downloads directory and pick JUMP.BA

Notice at the bottom of your CloudT window that "JUMP.BA" is now on your

Enter BASIC

Type CLOAD
