- Clean up, Review, Test the TOP 2004 Universal Programmer. It is USB based and claims to do 21v and 25v chips but this one fails to do that. Overall, it would be fine for lower voltage programming but not good for Arcade Game purposes.
Decent review of the programmer.

I binge watched your chip programmers playlist yesterday and today. Great stuff and very informative, thanks.
Darn, lost a long text mesage because the playlist moved to #14 automatically grrr. Stupid TH-cam should pause the playlist when someone is typing a message.
I am no expert but have learned quite a bit just by using all the different ones. Glad it was informative.
great video.
can you test a bunch of TTL chips to see how it works?
i was hoping you were going to do that in the video.
that would be what i would use it for.
it being USB only would mean it is plug and play quickly without having another power source to worry about.
i don't need it for programming any eproms or other type devices.
i have other programmers for that purpose.
i would be cool if it works good on TTL chips so i don't spend money on another USB programmer to do the same thing.
thanks for testing it and making an interesting detailed video.
Hey Buffett! Yea, I didn't do TTL testing in the video but did just test several 74xx chips (04, 367, 02, 32, 151, 157, 175, 86, 174, 386, 00, 153) and they all tested fine in the TOP2004. There were false negatives on 74ls163 and 164. Actually, both my bk864 and the top2004 had false negative on 3 different ls163 chips and I had to go to my TL866, which tested them fine. The lesson here , on any of these programmers that do ttl testing, is try to test known good as well as suspect bad to give you a clue. Not all the programmers have good vector tests for all ttl chips. I might do a future video on this TTL testing feature, as it drives me crazy when test equipment has errors leading you to not trust results.
I would say the top2004 is fine for testing eproms and ttl chips. Nice handy USB powered that can easily go on the road. Save the 25v chip programming for the older or external/beefier power supply ones.
Your XP computer has many icons on the desktop that can lower the overall responsiveness. I would recommend putting these icons in dedicated folders, so you have 5-6 icons on the screen max. Large number of icons bogs down explorer.exe, given that it's an old computer and old video card with low VRAM. Some cases explorer.exe can crash, resulting in momentary freezes and then icons on the screen refreshing and all the open windows disappearing.
If I recall correctly, you have 768MB Ram (hopefully 2x256MB plus 2x128MB). You can upgrade for peanuts to 1GB or even 2GB with matching sticks (make sure the RAM is not lower frequency than what your mobo/CPU can support). If RAM is matching with the RAM in one of your other computers, maybe you could use 2x256MB somewhere else?
Also, I would recommend checking all the caps for bulging and black mass leakage on top of radial ones in your computers (including power supply). There was a lot of problems with Pentium IVs and Core 2 era caps. Same probably was with Pentium III era (didn't repair many of these and didn't replace caps back then, people just changed motherboards). Optiplex GX280 was especially notorious for bad power supply due to crappy caps. Many Dell Dimensions suffered as well, but it was not limited to Dell.
I must have missed this comment. I will clean up that desktop :)
@@jacklick With the amount of computers I use and all the stuff I do here, I struggle with these darn icons all the time as well lol.
Btw, you will be just fine with 1GB RAM in Windows XP (pushing it to 2GB is not that necessary). 1.5GB is doable as well (so you could get either two sticks of 256MB or 2x512MB) and replace the 2x128MB. I'm sure you know this, but find out what's the fastest RAM your old system supports and go from there. PC2700 DDR was my sweet spot for laptops and either PC2700 or PC3200 for desktops. If you use serial/parallel ports, faster is not always better, so I would just match the speed your 2x256MB sticks have, even if they are PC2100. You will benefit from having more RAM over the speed with the stuff you do on that computer. Preferably find the exact 2 same sticks that you already have for peace of mind. Certainly go with major brands and beware of "Brand new", as these are some Chinese knock-offs. Some of them use major brand name with questionable stickers and are "Brand new", so stay away from these as well.
Old systems liked lower density chips, so you are better off with 4 sticks instead of 2 for the same amount of RAM (with the new Ryzen and Intel systems it's the opposite lol).
Upgrading 2 of the sticks shouldn't cost you more than $10 these days.:)
I'm trying to burn some super Nintendo roms on a 27c801. and it always gives this error: 008000:error!(file=e2,chip=00) My label is top2049...I've been there for a week and I haven't been able to find the error. do you have any solution?
Sorry. I don't have this programmer and probably don't have the software installed. I assume you have verified the eprom is blank and are programming on slowest speed? I might try a selecting a generic 27c080 12.7 VPP chip and seeing if it programs.
The software is the same as the video, TOPWIN.
It always gives the same error:
008000:Error!(file=e2,chip=00)
I've already used 5 different eproms.@@jacklick
link do aparelho do driver donlowds
I showed in the video but here is the link and look for top2004 www.mcumall.com/downloads/
How do you install that "reload usb driver"?
IIRC, it was installed with the exe file that was downloaded from mcumall.
What is determining the Data Length? because sometimes it says 800 or 1000 or 2000 depending on the IC chip. I'm not sure if all universal programmers have that FILL Option on the start address and end address to FILL in 01. Does it say in the manual or somewhere how many milliamps of current for each voltage setting when testing IC chips at 5v,9v,12v,21v,25v to know what the milliamps of current at each voltage test?
The type of chip is determining the size 800 = 2KB, 1000=4KB. Most programmer software have a buffer editor and fill option. The manual doesn't say what voltages are supported only one device types are supported.
@@jacklick How do you test if a Universal programmer can output 21volts and 25volts because most Universal Programmers will drop the voltage or can't test IC chips at high voltages like 21 volts and 25 volts. Do you measure with a DVM meter to check if the universal programmer is testing the IC chip at 25 volts? The EEPROM and EPROM chips need a certain current for them to get charged and recharge for programming them. I thought the manual would state the current millamps for each voltage tests because I'm not sure how you can measure the current while the IC chip is being erased and programmed.
@@jacklick What calculation formula did you use to come up with the size 800 will be 2KB and 1000 data size will be 4KB?
I just use windows programming calculator but if you want to know how to do it manually see www.rapidtables.com/convert/number/decimal-to-hex.html
I am sure there is a way to measure it more scientifically but my test was just trying program the eproms. We could also look at the voltage upconverter and probably do some math on whether 500ma @ 5v (stated input spec of device) would be enough to provide required amps (i think @ 100ma) at 25v. I am not an electrical engineer but this why many usb programmer struggle to program these high voltage chips without external 12v 1A power supply.
