PCBs received

[jltursan]

Yep, some friends and myself are going to try to build some Dreamdisk controllers; so I've just received some PCBs from JLPCB and we're ready to buy the components.

I've finished a parts list in Mouser; so if anyone is interested (it won't be 100% tested until the first controller work) I can publish here the link.

Aweseome

Do you plan to sell a ready to use board?

[jltursan]

Not really, it's only a small private run and everyone is going to build the PCB by himself.

I've 5 PCBs and 3 will be assembled; so 2 of them are spares, are you interested in one?

Hi All,

The mouser parts list that I ordered from to build my first unit (that works 100%) is located here.

File is Bill of Materials Spreadsheet (.XLSX)

For R5 - You will most likely want to use a 25 turn multi turn pot instead of a single turn 50K as R5 is for Phase comparator Adjustment (RPW Pin).

I used this one:
https://www.altronics.com.au/p/r2386a-r ... n-trimpot/

For the WD2793 chip - I got mine from Ebay. Do a search there are a few sellers around the world including China.

I have some spare PCB's from JLCPCB as well - if anyone doesn't want to order a minimum batch of 5 pcbs from JLCPCB.

I also have some spare pairs of 2716 EPROMS (2 x 2716) programmed with SCUAMONv3.4 (with Dreamdisk FDC support).

Don't forget you will also need a Gotek USB floppy drive emulator with FlashFloppy software loaded on the Gotek.

Thanks for the offer. As johnhalk got the PCB and the roms, I will take his offer, as I don't have the materiel to flash those roms.

Hi, I'm interested into a PCB + programmed EPROMS!

Any trustworthy sellers out there you can recommend?

Just in case, you can find WD2793s into most MSX Disk controllers and many Atari 1050 disk units. In fact I already have a WD2793 replaced from an Atari 1050 with a WD2797.

Hello,

Please send me a private message with your postal details.

I will send you via Australia post airmail a blank PCB and a pair of 2716 eproms already burned with SCUAMON 3.4.

I am not recommending them though so please make your own decision !
