#4130200 The best type in magazine programs

Posted by russg on Tue Oct 9, 2018 1:12 PM

Where can I find it?

Issue 5-2 I think, issue 33

 

Has 'slalom', but maybe that's not the one.




#4129623 1050 DC in plug size

Posted by russg on Mon Oct 8, 2018 12:56 PM

Can anyone please tell me the diameter of the centre pin on a 1050 disk drive please? I've bought a couple of new 3a 9v AC transformers and the plugs supplied are slightly too small and i'd like to see if I can get a small adapter for the plugs instead of cutting them off and soldering on new one's  :)

You have a 1050, so you can see it's approximate size.  I would guess 1 mm.  I don't have a micrometer to measure it with.

Cutting off a 1050 AC adapter plug would be straightforward.  You don't have a stock1050 power adapter to get the plug from.

Wait..  you have a busted 1050 power supply,  Using that would be easier than getting an exact plug.




#4105850 problem with Atari basic

Posted by russg on Tue Sep 4, 2018 7:36 PM

As for inkey$ - A quick google search

As mentioned earlier, the version of BASIC for Atari's eight-bit computers has no built-in statement designed specifically to retrieve a single keypress. However, you can achieve the same effect by first opening a channel to the keyboard device with the statement OPEN #1, 4, 0, "K:", then using GET#1 to retrieve character values. (Any unused file number in the range 17 can be substituted for the 1 in these statements). The main difference between the Atari's GET#, and the INPUT$ and GET commands described above, is that GET# returns character code values rather than string characters, so GET# must always be followed by a numeric variable. If characters are desired, the CHR$ function can be used. Also, note that GET# waits for a key to be pressed.

To modify the first example program segment in this article for eight-bit Ataris, you must first add lines to open the channel for input and set up the testing variable:

100 OPEN #1, 4, 0, "K"
110 DIM K$(1)
This needs to be done only once in the program, but it must be done before the first GET# command. Then replace line 210 with:

210 GET #1, K : K$ = CHR$(K)
You may find it easier to simply check for character code values rather than characters. Refer to your BASIC manual for a complete list of Atari ASCII codes. For example, you could test for a RETURN keypress with

300 PRINT "PRESS RETURN TO CONTINUE."
310 GET#1, R:IF R< >155 THEN 310

line 100 needs a colon in the quotes  OPEN #1,4,0,"K:"

 

devices for OPEN are:

C: recorder

D(n): disk drive

E: screen editor

K: key  press

P: printer

R(n): serial port

S: screen  (how?)  you can only output to the screen

 

I think E: and K: do the same thing.

no E: can only 8, output,

12 keyboard input & screen output

13 screen input & output  (from Poole and McNiff 'Your Atari Computer"

 

You had it in the paragraph correct.

I think, don't use "E:"




#4105371 Atari XL White/Cream Paint Color

Posted by russg on Tue Sep 4, 2018 7:59 AM

sorry to sidetrack, but does anyone know a good match for the XL brown?

I don't know anything about spray paints.

But the XLs are white and black.  The 400/800 are brown/tan.




#4082114 Picked up my first orginal 1979 Atari 800 computer, need advice on parts

Posted by russg on Mon Jul 30, 2018 6:26 AM

Best Electronics (408-278-1070) sells entire keyboards.   I doubt you can buy just

individual keys.

 

Best Electronics

408-278-1070  1:30 PM to 5 PM Pacific Standard Time (PST)  Mon - Fri

I don't work for them.

 

It might help if you show a picture of the missing key place.




#4020580 Rana 1000 - loose part inside

Posted by russg on Thu May 3, 2018 3:10 PM

Here's a pic of mine at the motor like yours.

Uhm...   can't seem to add a pic.

keep trying.

that disc in yours just looks like it came off the top of the motor.

It doesn't do anything.

#3909252 Help with converting a Microsoft Basic line to Atari Basic

Posted by russg on Mon Dec 11, 2017 6:26 AM

10 CLOSE #1

20 OPEN #1,8,0,"P:"

30 FOR N =1 TO 10

40 READ A:PUT #1;A

50 NEXT N

60 CLOSE #1

100 DATA 1,2,3,4,5,ANY NUMBER TO 10 ENTRIES

 

THE DATA SHOULD BE THE ASCII CODES FOR THE CHARACTER YOU WANT TO SEND.

EG. 65 FOR A "A"

 

 

It has been a long time, so I think it is correct.

 

The 850 should recognize the "P:" device.

 

You don't want to use "LPT"s.

 

The 'A's in line 40 could be any letter, like "X"




#3854633 Atari 8-Bit Cartridges - A Big List!

Posted by russg on Sun Sep 24, 2017 7:16 PM

I have the SpartaDOS x and R-Time 8 carts.

I have a 800XL with Omnimon, so I can dump any cart.

What I don't know is the memory ranges and execution locations.

I can insert the cart, hit SELECT RESET (if I remember) and then dump any

cart code to file(s).

If someone knows the code locations, I think I can do them.

A simple cart, like BASIC, is $A000 to $BFFF. and executes

at $A000.

I don't really  know if my SPX and RT8 carts still work.

And I forget where the INIT and RUN codes are.

A little more:  I think SpX is a bank switched cart.  I don't

know how those work.




#3844186 G: Handler (SDX compatible if poosible). :)

Posted by russg on Sat Sep 9, 2017 12:34 PM

Thanx, I'll try.

Here's an .ATR from Oct. 1985 ANALOG that has the 'G' device source and .BAS executable.

It was by Charles F. Johnson.

 

It has to be a 100% compatible to Epson or Star dot matrix printer.

I don't know if it will work with a  modern inkjet.

#3804927 Bad news about myselve (Stormtrooper /Richard Vermeulen)

Posted by russg on Thu Jul 13, 2017 12:34 PM

BAD NEWS: I am forgetting things. Today, i didnt know my Facebook pasword nor my e-mail pasword, while I use the pasword every day more than 5 years. Also sometimes when I went to the toilet and then go back to my computer, 5 minutes later i cant remember if i actually went to the toilet. sometimes i dont remember words for ordinary things like a basket or newspaper. Korsakov / Dementia ? I might even forget my family and friends... but do my my dear friends and family remember me ?

---------------
In Dutch

SLECHT NIEUWS : Het gaat niet zo goed met mij. Ik vergeet veel dingen. Ik wist vandaag niet eens mijn wachtwoord meer voor e-mail en faceboek, terwijl ik dat elke dag al meer dan 5 jaar gebruik... Ik heb ook regelmatig dat ik naar de WC ben geweest en dan ga computeren en 5 minuten later niet eens meer weet of ik uberhaupt naar de WC ben geweest. Soms weet ik woorden niet meer voor alledaagse zaken. Zoals het woord "vensterbank", "asbak" enzo... dat is foute boel. Korsakov / Dementie ? Dadelijk vergeet ik mijn geliefden ook. Of zijn ze mij ondertussen al vergeten ?

 

I will talk with my doctor about having a memory test in the hospital. I also have headaches since 3 months. I fear the bad things. Wish me luck.

I can't remember my facebook password, or just about any passwords.  I have a five page spreadsheet with 137 usr and pswds.  Speedcalc, MS Excel are good spreadsheet programs.




#3775966 Paperclip Dongle

#3775695 Paperclip Dongle

Posted by russg on Sat Jun 3, 2017 5:53 PM

An LFSR maybe? Might make sense for a simple dongle, as it's easy to simulate in software (clock in a few random bits, check the output against the software version) but still reasonably non-trivial to replace for a prospective copier. Probably about as good hardware protection as you can get on an 6502. These boxes certainly won't be doing RSA.

here's the inside of mine.  I doubt it still works.

#3771351 Atari 600xl green and beige screen

Posted by russg on Sun May 28, 2017 1:23 PM

Still get the blank screen, in fact, the first thing I did when I got it hooked up was to try to boot it into self-test.

I looked for Red/brown screen in my docs.  It said the following:

U2 thru U5, U18, U19, U28, U30.  and I would guess Antic or GTIA U7 and U17.

All those mean swapping chips with known good ones.

 

U2 Decoder ; 74LS138

U3 Memory manager

U4 OS ROM

U5  BAS ROM

U18 CO17097

U19  CO61850

U28 Latch 74LS37S

U30  And/Or inverter 74LS51

 

That's not much help, but what I researched about it.

You could take out the BAS ROM and see if you still get the red/brown screen.

It would boot to a blue screen.

I'd start with the OS ROM, Antic and GTIA.

 

If you have socketed chips, that would help a lot.

 

I just tried it, taking the BAS out of a good board.  It boots to the self test like you said.

I don't feel any of the ram chips getting hot.

If the DRAMs are MT on them, they are bad.




#3743931 Antic Magazine ATRs

Posted by russg on Tue Apr 18, 2017 4:18 AM

It's not the link, it's the attachment below it that has the 8-bit ATR's for the 6 issues of Start.

 

I do not have a list of the the exact issues and programs that are missing. I just know some of them are missing. The early issues might have one or two of the games in the issue but other stuff is missing. For example, they did programs in other languages like LOGO and PILOT and those are not on those disks usually.

 

Allan

Complete list of Antic Magazines
 
Antic began publication 4/82, Volume 1, Issue 1.
They were bi-monthly for the first Volume, six issues.
Starting 4/83 (Vol. 2:1), Antic became monthly.
They published monthly until 9/89, missing only one month
(5/84), making the volume year end with April issue instead
of March issue.  That's 65 consecutive monthly issues from
2:1 to 8:5.
 
Starting 10-11/89, Antic became bi-monthly again (issue
8:6), and were bi-monthly for only 5 issues. Volume 8 only
had 8 issues.  10-11/89 (8:6), 12-1/89-90 (8:7), 2-3/90
(8:  8 ), 4-5/90 (9:1) and 6-7/90 (9:2), <-- the last issue of
a separate Antic.  There was no 8-9/90 Antic. Then Antic was
put as a section of STart magazine for 4 issues (10, 11, 12,
1/90-91).  Then STart, still with an Antic 8-bit section,
went bi-monthly for the last 2 issues (2-3/91 and 4-5/91)
then STart folded and that was the end of Antic and STart.
 
List of Issues/Volumes:
Vol. 1 -  Six issues (4-5/82, 1:1) to 2-3/83, 1:6)
Vol. 2 -  12 issues, all monthly
          4/83, 2:1 to 3/84, 2:12
Vol. 3 -  12 issues, but no 5/84, so Volume year now ends
          April instead of March.
          4/84, 3:1, (no 5/84), 6/84, 3:2 to 4/85, 3:12.
Vol. 4 - 12 issues, 5/85, 4:1 to 4/86, 4:12.
Vol. 5 - 12 issues, 5/86, 5:1 to 4/87, 5:12.
Vol. 6 - 12 issues, 5/87, 6:1 to 4/88, 6:12.
Vol. 7 - 12 issues, 5/88, 7:1 to 4/89, 7:12.
Vol. 8 - 8 issues.
         5/89 (8:1), 6/89 (8:2), 7/89 (8:3), 8/89 (8:4),
         9/89 (8:5), then bi-monthly 10-11/89 (8:6),
         12-1/89-90 (8:7), 2-3/90 (8: 8 ).
Vol. 9 - 2 issues.
         4-5/90 (9:1), 6-7/90 (9:2) <-- Last issue of
         separate Antic.  No 8-9/90 Antic.
Then Antic was put as section of STart magazine for 4
monthly issues (10, 11, 12, 1/90-91). Then STart went
bi-monthly (2-3/91 and 4-5/91) <-- Last issue of STart with
Antic section.
That's 94 issues total, including issues in STart, 88
separate issues of Antic.
