Chess, anyone? Any more H8T format archives?

[cole erskine]

Hi guys,

Just got my "new" H8/H9 up and running. I'm using Mike's tips from April to use the KCS utility to convert H8T files to WAV files (works great, thanks Mike!) and loading/running those.

Looking specifically for a chess program, but I couldn't get H8CHESS.WAV to run (tried hitting the space bar a couple times to no avail). MYCHESS on Mark Garlanger's site is only available in H8D format.

So far the only .H8T format archives I can find are the "Heath Tape" and the "HUG_885-1009 Tape", both on the SEBHC web site.

Any other sources for H8T files? Or cassette image audio WAV files besides those on Mark's site?

Thanks!

-Cole

I can help with this but am about to go on a road trip with my son to upstate NY. If you’re not aware we have some cassette software archived

https://sebhc.github.io/sebhc/software.html#Cassette_Tape_Images

We also have an ability to create new H8T files from .ABS executables. I even have some games for the HA-8-3 graphics card that I’ve written that can be run from H8T.

Take a look at the above URL and we can chat more when I return (Sunday)

Hi Glenn,

Thank you for the quick reply.

Wow, thanks, I’ll check out the .ABS threads!

I am aware of the Cassette Tape Images on the SEBHC site.

I’ve come to realize the simplicity and elegance of the original H8 tape-based loading (which ironically I never used in the old days as I started out with a disk-based setup) I was first inspired by Erik Ackerman’s clean demo

https://youtu.be/NC2BOBhqork

Which uses only the h8 plus a laptop to simulate the tape system and console. Then add Dave Runkle’s adapter that lets you read digital (H8T) images instead of audio (WAV) and you’ve got the basis for a nice easy demo setup. Mike Ladwig has built a cool digital replacement for the tape player and Joe Travis has added speed up and USB capability. Finally, add the new enhanced H8-5 board that Norberto is now completing and suddenly you don’t need a disk system at all to do fun stuff with an H8. Don’t need much RAM either, as there’s no OS. Hopefully this will open the hobby to more people who don’t have functional disk systems. Also makes for a nice simple, reliable way to do demos at VCF and other events.

But we need to gather up some software to make this all be useful, and some of the earliest games and demos have been hard to track down. We may only have hard copy of some, as the earliest HUG volumes were published in print format.

My atoh (ABS to H8T) program lets us build software on a disk-based (HDOS) setup and run the program via the cassette download, but of course the source code must be free of any operating system calls.

I look forward to getting a more complete collection of interesting games and demos, and to documenting all of this. We can also write new programs as I’ve developed the steps to compile C programs to H8T executables.

If you’re interested make sure you’ve read my REMarks write up, which is my first attempt at capturing some of this knowledge…

I did try H8CHESS.H8T in my H8 system and nothing on either console... It looks broken so far.

Thank you for trying it, I see you’re an expert here so I feel better now!  ;-)

[norberto.collado koyado.com]

No really! I'm just re-learning again. 

I depend a lot on this group's help and for their professional advice to keep me honest and on the right track.

As a team, a lot has been achieved.

Here's a copy of H8CHESS.H8T that runs on my computer.  It uses the H8-5 serial port.  If running it on a H9 terminal, when the program prompts you with "BIG BOARD?" enter 0 (zero) and <RETURN> otherwise the board will be too big for the H9 display.  Enjoy!

Regards,

Joe Travis n6ypc

Thank you, Joe! As Norberto and Rick have already noted, this version of H8CHESS.H8T that you uploaded works just fine. However,

it is NOT the same as the H8CHESS.H8T in tape-images.zip at https://sebhc.github.io/sebhc/software.html#Cassette_Tape_Images

File size and name are the same, but the one in the Heath tape archive is different than Joe's version and doesn't work.

Thanks, guys, for all the help! I'm using chess as my demo program for my H8 exhibit at VCF West this weekend in Mountain View!

-Cole

[Richard Davis Jr.]

The version I used is from the tape images.zip. Is this the one you say doesn't work?

Yes. I'm also using an H8-5, but I do have a Z80 CPU. Could there be something that only allows that version to run on an 8080?

-Cole

[Joseph Travis]

Cole,

There's no issue with the Z80 vs. 8080 in this instance. You probably had a bad copy of the program is all.

[glenn.f...@gmail.com]

The version that Joe posted differs from the one on the github site but almost all the differences are in the first sector, which is probably the I/O front end.  I was guessing that perhaps the version from the github site was for the 8250 (H8-4) console but I was unable to get it to respond (I didn’t hook up the H9 but Cole already tried that).  I’ll take a closer look to see if I can  understand the difference.  If both are worth keeping we’ll have to give them different names of course.

 

I don’t’ know how good a chess game this is but its impressive that it fits in 6k…

On Level 1, the computer moves very quickly but I checkmated it in six moves. On Level 2, it can take between 20-60 seconds per move, but the computer still only survives for 20+ moves.

I'm going to try to get MYCHESS running next. Written by David Kittinger (author of Chessmaster 2000), MyChess competed quite successfully in computer chess tournaments from '79 to '81.

-Cole

[Joseph Travis]

MyChess is disk based (CP/M or HDOS), can be run in ASCII text or H19 graphics modes and would be difficult to play using a H9.  You are correct, it was very well regarded back in the day.

There’s also Sargon. We have source for that…

I saw Rick’s post in January about his Sargon 8080 H8 port. Very impressive.
