[M100] REX Question: Flash Wear Leveling

I have been developing a number of programs lately on my T102 w/REX, backing up frequently, and was wondering if the REX control software was doing any "wear leveling" of the Flash sectors. Having worked with Flash memory in my previous job (Point of Sale Credit Card machines) I know that it is

Re: [M100] an unusual ebay T102

Strange that the seller claims that 10% of the sale goes to a charity, when the asking price is 300% of the going rate for an incomplete unit (no manuals, damaged box). Unfortunately most eBay sellers seem to know nothing of what they sell, having acquired stuff from garage sales, Goodwill, etc.

[M100] REX Question

I was doing some fine tuning on a BASIC program, and when I used the System Menu command key "CTRL-B" to refresh the backup image of RAM, I got the message "Rebuilding Directories" (or some such, I didn't write it down) after the RAM image was updated. Is this message due to "wear leveling"

Re: [M100] M100 compact embedded ML coding

But wouldn't the 52 byte buffer mentioned below be wiped out if you typed"Edit" while in BASIC, to invoke TEXT to edit your basic program? The T102 ROM used the directory space of the three invisible files ( Suzuki, Hayashi, Ricky) for bug fixes, so I am not sure how the ROM accesses these

[M100] Serious REX Problem

I was doing some BASIC programming on my T102 using the Text editor. I put it down to attend to the laundry, and came back 15 or 20 minutes later to continue on with the T102, where I found that typing on the computer produced garbage characters on the screen and then the computer locked up. REX

[M100] dsub 25 hood that fits

You must remember that the M100 was created at a time when it was "the norm" to use flat ribbon cable to make connections to computer peripherals. This was true for parallel and serial connections to external devices (modems, printers, plotters, etc) as well as connection between two computers.

[M100] REX question

In the REX Manager (looking at the RAM group for example), the [s] key is supposed to toggle the sort order. This seems to alternate between "first to last" or "last to first", with the active image (the starred one) always first (top left display position). The displayed list is not sorted

Re: [M100] 102 com port power drain?

My cable has a USB-A connector on one end and a DB-25M connector on the other end. The DB-25M end is wired as DCE (the equivelant of a null modem adapter attached). So no gender changers, no DB-9/DB-25 adapters, no null-modem adapters. Just one clean cable. I got it in 2006, when there were

Re: [M100] Display goes blank when plugged into power adapter

This is normal operation. My 102 does this, and my M100 did this when it was new in the box in 1985. When the unit is powered on and running on batteries, plugging in external power briefly interrupts power as the power jack switches from battery to external power. This trips the internal
