I’m about a week away from being able to test (hopefully!) Todd

Thanks.

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. -Todd

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!

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.

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!

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.

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

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.

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! -Todd

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?

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.

Thanks. Where do people buy from?

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!

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.

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! R1000C-AA1.BIN

Can someone confirm what eprom I need for this? And which ROM image I need? Thank you!

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

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!

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! Print Shop Icons 1.pdf

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.

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... -Todd
