If you are running Vista or Windows 7 you need a signed driver or disable signed driver enforcement, XP should not care.

ADD: I had to turn off driver signing enforcement in Windows 7.
It said iit couldnt load the driver either for my GQ-2X, it did once I booted with Signed Driver Enforcement disabled.

I'm using XP. It kept telling me that a segment of the inf was invalid. The downloaded version was identical to the one that they put on the cd, and the forum section didn't have much.

Here is the thread that I found. They didn't solve the problem; they only had him use the old driver.

I'm wondering how much speed I'm losing because I'm being forced to use the old version?

First, the main one. Think of an EPROM as a notebook. A 27C64 has one page, and the larger 27C256 has 8 pages. The address lines tell the EPROM which page you're looking at. Since the 27C64 only has one page, it doesn't have enough addresses for eight - those pins are still there, but used for other things and tied to fixed voltages. When you drop in a 27C256, those fixed voltages select one of its 8 pages, which is probably not the one you wrote on. So the trick is to use the burner software to copy the same data to all eight pages, at 0000, 2000, 4000, 6000, 8000, A000, C000 and E000. Then it doesn't matter which page gets selected, you still read the same information. Load the 27C64 one-page data - it goes in at 0000 - then copy it to all the others one at a time, then burn the 27C512.

I realize this is an old thread, but all of the talk of using 'offsets' etc. when using a 27C512 is overcomplicating things. The simplist way to do it is just use the copy command with the /b (binary switch).

Where 1.bin is the name of the source 8k bin and 27512.bin is the output file in the example below. Make it a batch file and one click and you have an instant 27C512 file with 8 duplicate pages.

copy /b 1.bin+1.bin+1.bin+1.bin+1.bin+1.bin+1.bin+1.bin 27512.bin /b

Sorry if this was already posted, but I scanned over most of the thread and only saw more complicated ways to do it.

Neat shortcut poppo! Thanks for letting us know how to do it!

Good suggestion poppo. I don't think it's been posted previously, mostly because we don't seem to have many members who are DOS literate.

For the most part, I've been suggesting using HxD to members who have asked how to create paged files.



For the more advanced users, if you know which page the hardware is reading, you can insert a single copy of the file on that page and set the rest of the pages to 0x00 or leave them as 0xFF.

For example, the Gamemaker v7000 mains (4mb) read the top page on an 8mb chip. I believe that the graphics files (2mb) do as well on 4mb and 8mb. In other words, all of the extra address pins have power.

The S+ reads reel chips (64k) on page 7 of 8 on a 512k chip.

Of course, it's not really necessary to worry about all this. Burning a file with 8 copies of the same data is no big deal. I'm just anal, which everyone around here already knows.

This is the specs on the blanks I'm using...is it fast enough to use for reel eproms on a 16MHz board?

ADD>> double-click to make picture larger...

Frequency is the reciprocal of time so using a device with an access time of 55 ns the maximum speed would be 18.18 Mhz. The slowest device that you would be able to use (without introducing wait states) is 62.25 ns

The short answer, yes 55 ns is acceptable for a 16Mhz board

Did we set a new reply record?      2 years, 3 months, 3 weeks, less a day.


As long as we're here, it also depends on how many clock cycles occur between reads. Otherwise, by a 1:1 calculation, a 10MHz S+ would require a chip of 100ns or faster, and 200ns chips work in that board. I'm certain that 110ns (and probably slower) chips will work in a 16MHz S+ board.

Holy Moly dhellis!!
I've been waiting for your answer for quite awhile...thanks!
When did they let you out of Alcatraz?

Just got out today LOL


Apparently I paid not attention to the date of your question and since no one gave you an answer, I though what the heck.

NOW I getting ribbed for being the quickest draw on the board

haha! Welcome to NewLifeGames dhellis!!!!  

It's not ALL serious here but we DO like to try to help out each other!

Dhellis, thought you could use a virtual towel to dry yourself off, so I gave you a karma for jumping right into the deep end of our pool.   

Oh, yeah, and

Thanks,
My wife said that she will scrape the egg  off of my face and that I can have them for breakfast.

Wow! Holy Thread revival fordsbs!
That was when that Statfreak guy kept picking on me...
