Re: Another Classic Ported to TRS-80 MC-10

RESTORE, as Pippa said, just returns to the beginning. Normally you either load arrays or simply do a number of "dummy" reads to get back to where you want. Alternatively, sine the MC-10 is a machine in the same vein as as the ZX81 and memory is at a premium, you load data directly into arrays from ...

Re: Another Classic Ported to TRS-80 MC-10

Pippa

The crown is mine!

What does these POKEs do? You say you don't know much about the MC-10 but it seems that you have figured out how to reset the RESTORE point for use by the READ command. Have I got that right? If so, this is a very useful set of POKEs.

Re: Another Classic Ported to TRS-80 MC-10

Not bad news -- great news! And thanks so much for tracking down the solution.

Ta,

Sorry to bring bad news, but your port of Atlantis has a bug in it. If you type HELP the program crashes with:
?UL ERROR IN 471

Anyway, I've tracked down the original source code in the Captain 80 Book of ...

Re: Solaris, Sinclair Spectrum text adventure - Softel 1983

Thanks for the source Pippa. Sounds intriguing. Maybe I can backward engineer a verb list by guessing and create my own parser subroutine. Ta.

Re: Any Sherlock Holmes BASIC Adventures?

Completed my port of The Search for Sherlock Holmes to MC-10.

Noticed using Alex's playthrough that the phrase "BUY MEAT" didn't work. Don't think BUY is one of the verbs. GET MEAT works (and subtracts the money from your wallet).

Thanks again to everyone for the help and Alex for the playthrough.

Thanks so much. Never thought of the wayback machine. I'll have to remember that trick. Ta.

Re: Any Sherlock Holmes BASIC Adventures?

Can't find "The Search for Sherlock Holmes" for the C64 anywhere on the Net. All the Latif pages are 404. Has there been a massive sweeping of old software for the C64 from the Net?

Re: Any Sherlock Holmes BASIC Adventures?

I'd looked at the one for Atari, but it turned out to involve multiple files loading from disk. Didn't look at the others cause they came later historically so I assumed they would be m/l or be for powerful machines (i.e. too big), but the one from Lodestar (C64) actually looks promising. Thanks ...

Jörg Walkowiak's "Gold Fever"

Anyone have a copy of Jörg Walkowiak's "Gold Fever" from the book "Adventure Gamewriter's Handbook for Commodore 64?"
Its for the Commodore 64. Can't seem to find a copy on the Net. I'd like to port it too MC-10 and try to solve it.

Re: Solaris, Sinclair Spectrum text adventure - Softel 1983

Does the machine code do anything important in the game or is it from window dressing? If I could see the Basic code I could perhaps help you out. Any chance you could send it?

Any Sherlock Holmes BASIC Adventures?

I'm wondering if anyone is aware of any Sherlock Holmes themed BASIC language adventure programs? I'm aware that there are a number of fine M/L and higher level language games. What I'm looking for is something simpler, written in BASIC that will fit in a 16K machine. I have been quite surprised ...

Re: Another Classic Ported to TRS-80 MC-10

Neat. Funny about the improperly exited FOR/NEXT loops. MS Basic is tolerant of such. But I still often do something like the following with them:
455 IF C2$<>"" THEN TMP=I:I=L:NEXTI:I=TMP:GOTO 490

Sometimes the program expects to know what the value of the loop counter variable is, so I save it to ...
