I know there was a modification that could be done to get the Foundation 128k to be upgraded to 512k. Anyone have a link to the modification documentation?

either should work

That was me. I actually found these and was able to get a sample and they work good. https://www.te.com/usa-en/product-5530843-7.html

make sure you do not have the disk (or disk image) with the LOAD-TIP mounted in DSK1.

I've been looking for a 44 Position Straddle Mount Card Edge Connector for a project I'm working on. Like the one that is soldered onto the PCB of the Speech Synthesizer. Does anyone know a supplier?

I have not seen this posted in the repository. I created a module for use with the FlashROM and FinalGROM of HardMaster both 40 and 80 column versions. HM80.bin HM40.bin HMASTER4080.bin

I can't tell from the photo of the card but ensure your dip switch has all 4 position open (off). Also if your photo originally had the 10k resistor and now it does not, chances are the PEB cage hit it and ripped it off. I always will put a piece of electrical tape over this resistor as it's just too close to the cage. One thing to note. the clock chips control writing and accessing of the SRAM. If your battery is dead in the clock chip you will see errors when testing. i've gone through a Frankenstein battery replacement on these HERE

yes, it works with all Rasbperry Pi's. I have tested it as of today on Raspberry Pi, Pi2, Pi3 and Pi4

Thanks! i'll order some Samples. TE.com lets you order samples of that part and many others..

Nice. So I see the 2 xtra keys. What would these do, i'm thinking maybe a vote for those for most common used keys.. maybe insert and delete? Also like that you included the alpha lock/joystick fix.

I have a blank PEB backplane board for the PEB cards to plug into but it is not populated with the edge card connectors. Anyone have a source for the edge card connectors that they know works so i can purchase 8 of these. I think this one will work, but would like a 2nd or 3rd pair of eyes to verify. 5530843-7 by TE Connectivity | Connector Card Edge | Arrow.com

There is a Samsung 910mp up for sale on ebay. Looks to be a good price including shipping. Samsung SyncMaster 910MP S LCDTV Monitor With Remote* | eBay and for those that don't mind waiting for a 710mp from Poland: https://www.ebay.com/itm/193877156488?hash=item2d23faa288:g:O48AAOSw8KRgGmUp

To get the traces to work for the size i needed I had to make the board a little bigger than I originally wanted, but it will work. With the custom cable assemblies of course added to the price. I am estimating an assembled board with cables ready to go to be around $85 to $90 USD
