Dan O'Quinn's Turbo Pasc 99 Tutorial

[Dan O'Quinn's Turbo Pasc 99 Tutorial]

I might try writing Dan O'Quinn and see what happens. 😃

 

FWIW - There is a PDF of the manual on the CYC, that Mike converted, and I added fixes to, with the approval of LL Conner.

[reading/writing floppy sectors from Basic]

18 hours ago, Tursi said:

I wonder if there is more to it than that?

 

The issues I see there:

- what do you put into N$?

- how do you get around the need to match the file type?

- FIXED 255 gives you only 255 bytes, sectors are 256 bytes long

Yes, there was much more, the article was published in Micropendium, or is on the Cyc. But that was one line of defense in the copy protection, essentially Mike had to figure out what that line of code was doing. And essentially it matched with the question was in this thread, if not a perfect answer. It's as close to being done as can get in raw basic.

Speaking of Michael Becker. He had a number of my items in the magic basement in for repair.  He stopped answering emails all together.

My last communication with him was - If you don't want to do the repair thing anymore, please let me know, I understand.

I'd ask only that you take all my stuff to a shipping shop. Let them package it all at my expense, I will call or write them and pay for the packaging and shipping for get my stuff back. (tried that by both email and snail mail) - never heard back. It was all very odd.

Thanks,

Dan

Hi,

 Dan O'Quinn released a two diskette set called Turbo Pasc 99 Tutorial.

 Does anyone have a copy, that they would be willing to make available?

Thanks,

Dan

 

[reading/writing floppy sectors from Basic]

OPEN #1:N$,UPDATE,RELATIVE,INTERNAL,FIXED 255
with an FDR as set up above, essentially allows Basic to read and write disk sectors!

 

From Mike Wrights excellent article called Cracking Doom of Modular.

I'll be happy to investigate what package is in the cartridge. What the best way to determine such?

Thanks,

[PDS Sports [CC-40]]

 

I bought a cc-40 from ebay / salvation army. It works pretty well, I was lucky, in 2011 someone had put in Duracell batteries, which don't seem to leak as bad.

I pulled the old batteries out, and put in some new amazon branded batteries and everything came up.

I don't know if any has a list of software that was made exclusively for this machine, but would be happy to let someone dump PDS Sports - as this was a purpose built machine.

Even the carrying case is very high quality.

 mizapf - I've never seen it done in real life, but it seems like one should be able to plug a Hexbus floppy HX5102 in to a CC40. Does that work in mame?

Thanks,

Dan

 

[cc-40 / TI-74]

For a brief time, I had the development system for the cc-40. It was a Video Interface - I think it was composite out and gave a vt100 like typing experience.

 That coupled with the editor assembler module, and a hexbus drive (ti used those with all hexbus systems) made a solid e/a development platform for the cc-40.

 

  I believe these were given to a university in texas for their interns to develop all the modules for the cc-40. (Kind of like developing on your macbook air or your iphone! 😃 )

 

  O'well, maybe one day Michael Becker or Michael Bunyard will awake and say - you know I could make one super hexbus device with a Raspberry PI! 😃

 

Maybe I should be looking a cross development. Is there a software emulator for the cc-40?

 

Thanks,

Dano

[cc-40 / TI-74]

Supposedly the 99/4a was hampered because of it's display.

My question is what could you use the one line display offered up by the CC-40, and how would you use it?

dhe

[cc-40]

I've read a good bit on 99/4 (and perepherals) and TRS-80 Model 100 repairs but never seen much on CC-40 repair.

 

Anyone have in experiences they can share on CC-40 repair?

 

Thanks,

Dano

How about the psystem?

[ti994w for development.]

ti994w looks perfect for 99 development - in either c or assembler. I'm close to getting the tool chain complete, but could use some help from someone already working.

 

I put a sample hello_world.c99 file in /utl.

I'm able to compile with c99c.bat hello_world c99 - that creates /obj with assembler source code out of the c compiler.

I'm then able to do c99c.bat hello_world a99 - that create another /obj in obj with the assembled output.

 

There is another file l99.bat.

 

Questions: Where should my files live.

Assuming I have a perfect, non-problematic c program, what would I need to type to Compiler, Assemble, link, (hopefully) copy files to a /dskX directory and autorun with ti994w?

 

Thanks,

Dan

 

 

[Identify this card repost from reddit]

Mike Maksimik had one of those. It was an A/D card with battery backed up time clock (similar to the MBP card). I believe Mike wrote routines to interface mice and routines to set the data and time for the p-system.

[TI Review - magazine]

Yep... That's the one thanks.

[TI Review - magazine]

When I was in German, I saw a couple of editions of a German language magazine, I think the title was TI Review.

 

It was filled with boards, schematics and assembler code, not the usual TI stuff of the time like here is a Basic program that displays a star on the screen and scrolls it up one line.

 

Does anyone know if scans are available for purchase?

 

Thanks,

Dan

I can't remember. Did anything get worked out so 9640 Guys can run UCSD Pascal on the Geneve?

We have the same desk!

In my closet is my console with the Top Radio Supply of Chicago mod - w00t daughter board technology.

Also, on my desk is my trusty HP 16C. I like it much better than TI's LCD Programmer, which always had double bounce key problems.

Thanks for the photo.

[Pascal on the 99/4A]

I have found that the main limitation of working within the p-code environment to be the editor. Indentation is inherent to good Pascal programming, and thus the 40 col screen is poorly suited for this, and for long programs, the 24 line screen makes it very difficult to follow the program logic.

Using emulation helps alleviate some of these limitations because, at least with Classic99, you can code using a modern editor like Notepad++ and paste the source directly into the p-code editor for compilation and testing. This does mess up your indentations however, but it wouldn't matter (there might be a way around this within Notepad++). Emulation also is far more reliable, and in my case I only use the real hardware for testing purposes. I just transfer the work disk to the TI using HDX.

That said, for shorter programs, the native editor is fine, and at least for me, I still very much enjoy the experience of using real hardware

 

Your comment about indentation is also aprapo to c99.. I remember Mike Maksimik of the Chicago TI Users group had hacked an old 80 column terminal in to the P-System. So that might be one route, serial cable, PC and a terminal emulator?

Mike Wright has one, maybe someone could get him to document it in the cyc?

[HRD (Horizon Ramdisk) 2018]

Opry99er,

Thanks for the memories, it was a nice looking board and the guy that produced it Mike Ballumm (sp?) - was very knowledgeable. I was at the Chicago fair when these where released. Bud Mills about stroked out. I think the source of contention was that the original Ron Giles board and software was public domain the enhancements the Bud Mills service made where not.

Tim,

What file contains the PDMA - or is it a setting spread out amongst multiple files?

Thanks,
