I own a Timex Sinclair 1000 (NTSC version of the ZX81) and it displays no video... from what I've researched, the ULA chip is to blame for this. Are their replacements out there or are there substitutes?
-
Just buy something like this http://www.mycablemart.com/store/cart.php?m=product_detail&p=121&gclid=CjwKEAjw07nJBRDG_tvshefHhWQSJABRcE-ZbXvrMZXry9f7H8d2rWSNrx1gQHt-w2Ev-jhpx3k8iBoCj73w_wcB set the ID on each device to be different and then make sure that the device on the end of the cable is terminated.
What do you mean by "terminated"?

Price drop to 20 CAD.

I have an Amiga 2500, and I want to be able to put perhaps a zip disk or a cd rom drive into it but its occupied with a HDD already. I have a A2091 SCSI controller and I'm not very familiar with SCSI. The SCSI ribbon cable doesn't have multiple connectors on it like a floppy or IDE ribbon cable has on it. Does this only support one device or do I need to purchase a SCSI ribbon cable with multiple connectors on it?

I'm selling a 25 Canadian dollar iTunes card that I got as a gift that I don't need because I don't use iTunes. The store doesn't accept returns on these so I'm selling it here. I can part with it for
2320 Canadian Dollars. Paypal gift or you're paying the fees.
This will only work on the Canadian iTunes store.
But I will keep it open to world wide (useful if you want to buy an app that isn't available in your country).
I will send the code through PM but if you'd like, I can ship the card itself for around 2 dollars, depending on where you live.
Thanks, -
I know that the ST was used a lot in the music industry and some people say that it's still being used today. But has anyone really seen one in action at a studio these days?

As to installing the drive... you're familiar with opening up your computer, drive sled and all that? Pretty self explanatory once you get in there. Slip the drive in place, secure with a couple of screws, route your ribbon cable, etc. Fun stuff!
Well I meant more so on the software side of things.
-
Yes, Zip drives are supported via SCSI:

When needing to transfer files from a modern computer with internet to the Amiga, I've found CD Roms to work quite well. Very fast too and will fill the 5-1/4" bay nicely in your 2500.
How do I install a CDROM drive? I have Workbench 1.3 btw.
-
Is there any good way for me to transfer data to and from the Amiga? It doesn't have IDE so a CF card is a no go. I've done a little research and I've come up with either a null modem transfer, a SCSI CDrom drive or a ZIP drive. The null modem seems to be the easiest although I don't know how fast it is compared to CDrom or the ZIP drive. The ZIP drive seems to be the best option (because of re writable disks) but I don't know if the Amiga supports the zip drive through the SCSI. Any ideas?

If you have used a soldering iron before, you can replace the internal battery yourself. Luckily, all you need to open a dreamcast is a Phillips head screw driver.
-
It will work fine w/o battery, you can remove the battery just fine.
also, get a q-tip and clean the leak area with a Vinegar to neutralize the spill, and then with alcohol.
So a little update, I tried to remove the motherboard from the case, one of the screws was stripped and was way too tight. So I decided to use a dremel to cut a slit into the screw so that I can get it out with a flat head screw driver. This won't hurt anything right? I'm being very careful not to touch anything but the screw but it is taking a far bit of time to cut a decent slit into it.
Another thing, the power supply problem I had before, it turns out that it was the floppy drive that was causing the problem. I unplugged the floppy drive power cable and it booted right up.
Which tells me, there must be some sort of short in the floppy drive's circuitry.
-
You need to wiggle it from side to side.
alright so I tested all the voltages and they seem to be fine. And the fan is spinning as well.
EDIT: Ok, for some reason, I plugged it back into the amiga to see if it was working... it seemed to work fine this time.
So onto the battery. Luckily the battery hasnt leaked everywhere and only leaked in a small area where the battery terminals are and the battery still holds a charge. But I still want to get it out of there so that there isn't any further damage done to the board.
I don't have a button cell holder on me for the button cell mod, so will the amiga still operate without the battery? (not keeping date and time of course)
-
No, don't assume anything, you need to find the pinout with the description.
Use this site for reference: http://wordpress.hertell.nu/?p=282
As for getting out the power plug off the mobo... How do I do it exactly? I noticed a white tab and pressed it down and the plug doesnt want to budge...
-
yes i understand that, but should I just assume that the color codes are the same on modern ATX power supplies?
-
Unplug the cables from power supply to the motherboard, and turn the ps on, does the fan spin? Check the voltages, use google to find the pinout and voltages.
What type of connector does the power supply use to plug into the mobo?
-
Is it flashing everytime you turn it on?
Check if you did not drop a screw or something metal inside.
The power led should stay on when you switch it on.
Yes everytime. I have tried a few times.
I checked, I dont believe I dropped any kind of screw but I will check under the mobo if there is something wrong.
-
Lift it from the front and be careful not to drop it in the back or you may damage the flat video chip.
Alright thanks, I will try that.
Also another thing, I tried the amiga 2 hours ago without a monitor just to see if it were to boot and the HDD was spinning and seemed to be working.
However, when I tried it just now, the power light flashes for a second and nothing happens... did the PSU just brick itself?
-
hello everyone,
I recently got an Amiga 2500 and I wanted to inspect the battery and get that thing outta there.
But I try to unscrew all the screws to the drew cage (and the ones on the back) that are visible to me but the drive cage will just wiggle. I don't want to apply too much force on it.
Any suggestions?

2600 with 30 or so games for 2000 dollars.
-
I think I'll do grant searle's design. seems to be well documented.

Generally speaking, it depends on two things. How fast you want it to run, and how much power you need it to use. The low current 20mhz models that are sold cheaply on various auction sites will be more than enough for most applications. If you want to simplify things, like James suggested, you can use one of the various flavors of the z180. Again, it depends on what you're trying to do.
Where on that z80.info site should I start reading?
-
Well, if you're looking at doing a z80, then http://z80.info is the place to go. It has most of the information that you will need. Another is Grant Searle's website, found here: http://searle.hostei.com. Obviously reading the datasheet for the z80 family is a must: http://www.z80.info/zip/z80cpu_um.pdf. As well as the actual datasheets for the devices, along with any third party devices you decide to use (as mentioned above, Grant's z80 uses the Motorola 6850 UART).
What it comes down to, is you have a lot of reading and research to do. And if you're going to design your own, you'll need to do it
what version of the z80 should I use?
-
What are some good resources to read?
-
Is it particularly hard to build one? Also I have a timex sinclair 1000 which is based on the zx81. That would be a good reference on how its made.

Atari Portfolio LCD replacement
in Atari Portfolio
Posted
Hi, I have an Atari Portfolio that was an LCD discoloration and the bottom left hand quadrant of the screen is not visible. Is there some where I can get an LCD replacement?
