If you have roms but no burner, drop one in the mail and I will burn it for you and drop it back.  No charge, unless you want to send me another blank rom, which I will be happy to accept but which is not neccessary.  PM me for details.

 

Best,

 

Jeff

Jeff,

 

That is really cool of you to offer and I do appreciate it. However, for me, actually doing the burning is half the fun.

 

I just ordered some NMC27C32Q-45 that have a 12.5 V programming voltage. I am hoping I will be able to use those. If not, I will wait until I can get Dropcheck's burner which does work with 21V chips.

 

Thanks again.

So. I've decided to get @Dropcheck's burner when she gets more available. In the meantime, I assume that replacing the crystal without replacing the ROM is a bad idea?

 

Correct?

 

Thanks!

ok, i will do that. It is true that I asked for it a while back. Sompe people promised to help me but didn't hear from them anymore..

 

I think that was criticism directed at me. To be fair, I DID help you, but you kept asking for more and more. We discussed this in private and I thought you understood that I did not have unlimited time, but apparently not.

I'd investigate the loose power jack and solder it nicely, then I'd check power and exercise the dip switches... after that it's down to selection/sio chip fun.... make sure it's on the sio all by itself, and if you have all that new fangled stuff, that your config doesn't confuse the indus or vice versa

You are the king of trouble-shooters. I removed the 850 interface and plugged directly to the 800 and it works fine.

 

Not sure why the 850 causes the issue, and not sure why it got half way through booting paperclip before it said, "Wait, I'm not supposed to work this way" and stopped. 

 

Thanks!

[Rana ROM images]

This is really annoying. I mean, I know this stuff is old, but how can there not be a way to program these things? It's just crazy.

[Rana ROM images]

Sigh.

 

Anyone have a reasonably-priced recommendation for a 21V (or higher) burner?

 

Thanks.

[Indus GT Weirdness]

it wasn't an original disk. I made it from NOS blanks and an .atr. Why do you ask?

 

I actually bought paperclip off eBay a while back, so I have the original somewhere.

[Indus GT Weirdness]

Hi.

 

I have an Indus GT I was thinking of putting the sram charger in and updating the firmware. before starting I hooked it up to check it out. I have the Databyte 11.5 volt power supply. It fits very loosely, but it does power up. I put in what I thought was a dos disk and it booted to a black screen. At that point, I realized it was paperclip and I was running in 800 mode, so I was like no problem.

 

Turned off the computer, put in a dos 2.5 disk and turned it back on. It spins up, makes about a half SIO chirp and then ... nothing. It starts to spin down and then tries again, but doesn't do anything.

 

Anyone got any ideas?

 

Thanks!

I found some 2732's I had laying around, they are blank, but they do not burn.

error! address:0x000000 buffer data:0x01 verify:0xFF

 

I looked at them and they say 21V FAST on them. I assume that means I need a 21V burner? Mine only appears to do 18.

 

Am I interpreting this correctly?

Sp. What about a 16mHz or 32mHz crystal? Can we get this thing up to modern hard drive speeds?   

[EPROMS To Order?]

1 hour ago, R.Cade said:

It's much easier to just buy a bunch of cheap Winbond or ATMEL W27C256 or W27C512 EEPROMS. They can be used in place of any 28 pin EPROM. Make or buy some cheap 28->24 pin adapters and you have everything covered. To make smaller ROMs you just have to duplicate the data up to the size of the EEPROM.

 

Plus, they can be instantly reprogrammed- no waiting to erase and having old programmers with funny voltages, etc.

 

I’m having trouble finding 28 to 24 adapters. Is there a term I can search for to find it?

 

do the w27c512’s burn with the same eprom burner? How do you erase them?

 

thanks.

Yeah. It’s not a fun place to shop for multiple things. I’d rather pay a little more for a little more ... organized store. 

[EPROMS To Order?]

Thanks. Where do people buy from?

[EPROMS To Order?]

So, I decided I wanted to upgrade the firmware in my Rana drive and needed a 2732 EPROM.

 

I was faced with the familiar option. Spend more to get something relatively fast or pay next to nothing but wait forever.

 

So, does anyone have a list of EPROMS I should just order to have on hand for 8-bit stuff?

 

I'd love to have a little stockpile of chips so I can do these types of projects on the spur of the moment without having to wait for an order.

 

Thanks!

From the last line in the rom, I see that it is the same version as the one I just replaced the other day.

 

Best,

 

Jeff

Cool. Thanks. I just ordered some 2732's from Jameco. (Paid too much, but didn't want to wait forever to get them from China, which is kind of weird, since this drive has been sitting on a shelf for a long time.

 

Jeff, graciously is sending a crystal to me, it's clear I have a 8 MHz crystal and will need the change and I have to ROM that I need to burn saved off. So, I'm all set! Thanks, everyone!

 

Also, I loaded the ROM I need to burn into my burner and it does not have any RANA or other copyright information. Is that right? (It seems to have a lot of blank space at the end.)

 

Thank you.

[Rana ROM images]

I "think" I dumped the rom from mine. (This is the first time I've tried it.)

 

Did this work?

 

Is this different than what we already had?

 

Thanks!

the 40-pin chip at top-left is the intel 8031 type

the crystal is at top-right - the silver component with 2x wires coming out of it's left edge

the chip with the sticker is the EPROM

Can someone confirm what eprom I need for this?

 

And which ROM image I need?

 

Thank you!

[Rana ROM images]

Also, any idea why the one chip has a sticker? Think it might have been upgraded already?

[Rana ROM images]

Hi. I took mine sort. Not sure which drive I have. 
 

how can I tell?

 

here is a picture. 
 

also, where is the crystal?

 

thanks!

And here is the obj.

 

I just ran it.  I guess I liked flashy titles.  It's got a color strobing title.

 

I didn't even remember writing this thing until this thread popped up.  It's been 33 years, after all. 

 

Anyway, I don't have a printer hooked up, but I ran it and it will look for a Print Shop graphics disk.  If it finds one, it will load it (screen toggles between Loading and Thinking, 8 times, I think once per pic across the sheet) and then I get a long fart as it says Printing.  It repeats this for a long time, and then goes back to the main screen so that you can print out another disk.

 

I hope someone finds this useful.  If you print out some PS graphics disks, show us a pic of them.  I'd like to see what the results were.

 

Enjoy!

So, I'd love to use this to print all of the disks I have and share them, but it adds an extra line feed on each text line. Any chance that can be fixed?

 

Thanks!

So, I had a Rana 1000 and an Indus GT BITD. I got the Rana first, but other than just sounding feeble compared to the Atari 810 a friend had, it seemed to work fine.

 

Was this issue something that I might not have noticed? Or if it would have been noticed and I didn't have it, any idea why? (Unfortunately, the original Rana I had was lost long ago. the one I have now, I have not used much. 

 

I was thinking of going down to look for the issue, but not sure what to look for.

 

Thanks.

[Could Cassettes Have Been Faster]

Okay. Atari Cassette decks were based on industry-standard hardware, but they were custom for Atari.

 

Would it have been possible to alter the deck to use a head that could access both the "front and the "back (Both the top half and the bottom half of the cassette tape) to double the transfer speed?

 

I realize this could have created all kinds of other problems, like if someone doesn't realize how it works, fills the "front" of the cassette, turns it over and then obliterates what they just wrote while filling the "back".

 

But aside from that, would it have been possible? Would it have made the cassette decks terribly more expensive? Could the Atari have been able to handle decoding both streams at the same time to where it would truly be twice as fast? 

 

Could speed have been doubled again if it supported stereo tapes?

 

Just thinking out loud...

I was just thinking, should the Print Sheet utility that I posted here be posted to another thread or location?  Maybe to the Programming forum?  It really has nothing to do with this thread topic.  It's just that this thread jogged my memory about this tool that I wrote back in '87.

 

Apart from the usefulness of the tool, the source code is useful to show how to interpret a Print Shop graphics library disk.

 

I'm still pretty new here, so I'm not sure what the etiquette is for duplicate posts / spinning posts off into new topics.

 

I think that is not a bad idea. Maybe link back to this post in case anyone wants more information?
