New Reproduction PCBs Available!!

Post by darcoza » Fri Oct 26, 2018 10:17 am

Hi everyone!

I've just finished up work on some PCB designs and thought some of you here might be interested in them. I've got a handful of designs that I will be posting over the next couple of weeks but here is the first:

These are for 8Mbit Hirom or Lorom reproductions using the popular M27C801. This is especially handy for those who only have the popular Tl866 programmer as larger EPROMs are not supported. They come with Super CICs preprogrammed and soldered on as well as the capacitors so all you have to do is program the 801 slot it in and solder it. No swapbinning, no PIC programming, no wiring required. It's a huge time saver!

Here is a video of me demonstrating their use to a friend of mine:

I've got a small batch of them on Etsy here:

But I'm getting ready to place a much larger order very soon so if you are interested in this or other boards please let me know so I can more accurately order.

There is space on the boards for various LEDs also for transparent shells, I plan to assemble some with and without these. I also am finishing the final touches on a PCB that uses the 801 but also supports up to 256K of RAM for save states, a board that uses the M27C160 EPROM for 16Mbit games, and another that uses M27C322 with built in decoders and up to 256K RAM all coming very soon.

It might help you save a few pennies to use my port of the supercic key to the pic10f322, which is a little smaller.

Also, 27c800s are really amazingly expensive :( it might be worthwhile to include with solder jumpers to support the SST39 series of flash.

Wow! Thanks for the tip on the 10f322 I may have to make another revision to start using those in the future! and being able to program it through the cart slot would be super convenient!

Can you tell me a little more about these SST39? How much can they hold, what packages do they come in, operating voltage, and general price range? And can they be programmed on a TL866?

I can usually find M27C801s for about $2 and M27C160s and M27C322s for $1 are these that much cheaper?

Sorry for all the questions you just have me intrigued :) If these meet my design goals then I may have more versions I need to design quickly!
Thanks!

SST39SF010A, SST39SF020A, SST39SF040. 128KiB, 256KiB, 512KiB. DIP, PLCC, TSOP. 5V. Prices on the order of 80c/ up to $1.40/. Yes.

Cheapest prices are often direct from Microchip.

Apparently not. I'd heard much worse prices for the 27C800s.

The problem with selling only one board is that it costs about $3.50 to ship these in a padded envelope, so selling just one at $5 is a loss.

That leaves two options however, if you really just want one I can sell it to you for $8.50 to cover the shipping, or if you're willing to risk it, it can try shipping one of these in a regular envelope for a stamp. I haven't tried sending these this way and so I can make no guarantees about what might happen to it, and it won't have any sort of tracking or anything.

If you want to risk it we can try it :)

Yeah, I don't think I need padding for anything fancy just a regular envelope, I just want to check out the board itself. Send me a PM with your paypal e-mail. thanks.

Here's a link to the new boards using M27C160s!

https://www.etsy.com/listing/661906505/ ... ve_1&frs=1

I also received a batch of boards that take M27C322's and come preassembled with decoders to make the 322 8bit compatible, and they can accept up to 256k of SRAM. I just haven't had a chance to assemble any yet and get the listing posted. I'll get that up soon though, and if you can't wait just PM me and I'll get started on it faster!

How much would cost to ship it to Brazil?

Hmm, I went to enable international shipping on the listing but I noticed Brazil wasn't on the list of countries served. So looking around most shipping countries are telling me that shipping even a small padded envelope costs like $100 or more dollars! Do you or anyone else know of any cheaper ways to ship to Brazil? This is crazy I had no idea!

Because of Brazil's attempt at import substitution industrialization through customs duties, the cheapest way to ship something to Brazil is probably to license a company in Brazil to manufacture it on your behalf in a Brazilian factory.

Hmm that's problematic. Fisher, do you know of any board houses in Brazil? It may be easier to work out a deal for the PCB design files and then you can get them made locally instead of paying this crazy shipping cost.
