COUNTER ($09:0A)
The key timer element is a 16-bit free-running counter which is incremented by E (enable). It is cleared during reset
and is read-only with one exception: a write to the counter {$09} will preset it to $FFF8. This feature, intended for
testing, can disturb serial operations because the counter provides the SCI internal bit rate clock. TOF is set whenever
the counter contains all ones.

Here is a little more information about the 16-bit timer (counter) from the official MC6803 data sheet (attached below).

Just discovered another MC10 emulator.

Is this any better than Virtual MC10?

Re: Interesting Tandy MC10 link with software
I have just converted a few more games for the Dragon 32/64 but I need to know who is the author of KLONDIKE and SKYSCAPE (and the year they were first released) before uploading them.

Skyscape was published in Compute! magazine November 1985 and the author was Robert M. Simons.
I have no clue where Klondike came from. The original source code was probably typed in by me back in the 1980s.

Re: Interesting Tandy MC10 link with software
I seem to remember Klondike being scavenged from a PC listing (GWBasic), but it could have been from almost anywhere. Most of my ports are from basic code scavenged over the last 20 or so years ranging from old PDP systems to Atari magazines. All the card graphics and screen stuff is mine though.
Re: Interesting Tandy MC10 link with software
Thanks Jim! OK, I uploaded three of the games you recommended, and I'm willing to convert more if anyone asks.
BTW, You seem to have missed my post about the emulator.
Regards,
Steve

Re: Interesting Tandy MC10 link with software
I tried this emulator, but it is set up for the French AZERTY keyboard. This can be re-mapped, but this did not seem worth my while since James the Animal Tamer's emulators work pretty well. I especially like their ability to load ASCII listings of basic programs directly into the emulator using the "quicktype" function. This means I can easily edit the basic source in MS Wordpad, flip to the emulator and load the source in a second and run it, and then flip back to the source to make any needed changes, and so on. It's like working in the old Quick Basic/Borland Turbo Basic environments. It's perfect for basic programming work b/c there's no CSAVEing, CLOADing, LISTing involved and you can avoid the crippled editing capacities of the original MC-10 (there's no "Edit" command--you must re-type to correct a line).
That being said, I participate in several French forums for the Alice, and have converted a few programs to work with the AZERTY keyboard layout--my Sokoban, for example, and my Loderunner I think...

Here's a link to the Alice forum I mentioned:

By the by, I'm currently working on converting a listing from an old Aussie TRS-80 Model 1 mag ("80-Micro") for a text adventure called "Doctor Who."

Re: Interesting Tandy MC10 link with software
Just created a new game for the MC-10, which would be easily converted to the Dragon. It's for a basic programming contest. See: http://rsp.retrocomputacion.com/?lang=en
It's called "Penguino."
