#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


60 CLOSE #1




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.

#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



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.



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.

#3737645 BASIC games that won't load?

Posted by russg on Sun Apr 9, 2017 6:23 AM

no wonder I can't get it to do anything.

where are lines 20000 to 32011?

Actually, my .BAS only goes to 19008.  Still hoping to get upper lines or a more complete .BAS

It's missing lines 20000 to 32011,  there are 4-5 more sectors that weren't linked.

#3737287 BASIC games that won't load?

Posted by russg on Sat Apr 8, 2017 3:00 PM

ok, maybe i spoke a little too soon.


SALVAGEX did work on one version of the EGYPT file and made it LOAD-able again, but it seems to only be a portion of the program.


On the other version of the EGYPT file the SALVAGEX tool runs much longer and recovers more of the program, but then it gets an ERROR 164 and doesn't complete successfully.   Even so, it recovers quite a bit more of the code as LOAD-able.  


In both cases, this is still much better than what I had before.  At least I get more to work with.

However, if you there is a way to get this to recovery the ENTIRE file, that would of course be better.   :)


This is the error screen I get.

 attachicon.giferror running salvage.JPG


Both versions of the "EGYPT" file I am attempting to recover are in the examples message above attached as ATR files.


Any suggestions?


Thanks!  I will keep playing with it.


I think error 164 means you didn't set the .atr image in your emulator to be writeable.


Anyway.  I did EGYPT.BAS and got a complete LIST and then a SAVEd BASIC.

Here's a .ATR with the two on it.

I didn't play the game, but it seems to be working.


edit:  As usual, when I don't test something before posting it, it doesn't work right.

don't try to boot that .ATR.  The LIST and BAS files on the .ATR are good, but load them

after booting from a good boot image.  ie. boot a good .ATR, then LOAD or ENTER from

my .ATR

...but it won't restore the original variable names (obviously). I'm thinking it was some other corruption than intentionally wiping the table...because why would somebody do that to their own programs?

Yes, I don't remember if SALVAGE assigns variable names for all files, or just those with a mashed vnt.  I think it restores

names if the vnt is right.

#3736358 Video problem atari 130Xe

Posted by russg on Fri Apr 7, 2017 3:52 AM

Hmm, picture is going to be difficult, because i took the atari apart and desolderd the rf-modulator.


Don't know how to say it in proper English, but it's like a major snowstorm on my (LED)screen. Through the snow, you can see the blue screen with the text ready, which seems to be ok exept from the snow.

It's a 130XE.  The MT memory chips are frequent problem.  Maybe if you touch the chips, you will feel one or more

getting warm.  I don't know another way to check those chips.  Well, you can see if they are MT chips by the

logo on the chip.

What would be great would be someone who knows what a logic probe or oscilloscope might tell you about

the MT chips.


OH! WAIT.   I do have a Sam's for the 130XE. Here's the page about video.  It won't help much unless

you have good electronics technician skills.

Another edit:  GTIA and Antic are important video chips.Antic U7 and GTIA U17. How you check them?

Uh, swap them with known good ones.  Or check the waveforms with oscilloscope.
