For Sale 1581 Replica board smd

[pazuzu72]

I made the SMD version of Commodore 1581 board starting from the service manual I brought the schematic to Eagle cad and then I created the SMD version.
The PCB measures 100x80 mm.

Look how small it is compared to a floppy disk (see photo)

The idea of the card was born mainly to be used for a personal project (I'm trying to place a slim drive and the board inside a C64C) but it could be inserted in a 64SX or inside a C128 for example . Or you could create a mini case to 3D print.

On the board there are headers for power, IEC, status LEDs and drive power.
Then there are a jumper for double kernal and 2 jumpers for selecting the Device ID (8,9,10,11).

There are the standard connector for the drive (34pin) and the connector for flat cable (26pin) for the slim drives (not included)

In addition to the complete and tested board, the cables for the power supply (not the drive one but the board one), the IEC bus (only cable not DIN) and the status LEDs are also included (see photos for details). Nothing else is included.

Only 5v are required for power. So if you have any units that need 12v (never found one honestly, maybe just the older ones) you need to supply them separately.

Eventually you will need:

- A way to power the board (5 volts)
- A data cable for the drive (normal 34-pin or flat 26-pin for thin drives).
- A drive power cable (only if using the 34-pin data cable).
- LED to be used and positioned at will for drive activity.

Assembled and tested... Are you saying that the 8520, 1722, and 6502 are all on board? I just want to be clear before I order one.

 

[pazuzu72]

Yes. Assembled as shown in the photo. Included MOS8520 and WD1770. The only components through hole, the cpu is SMD.

 

[pazuzu72]

In short, I send the assembled card and the 3 cables for the respective header connectors.

 

[dhoelzer]

Sounds great. DM me the details for payment and I'll send you shipping info and make payment today! Thanks!

Does the design also include the extra READY signal generation circuitry, so standard 3.5" FDD's can be used?
And will you ship the board and parts (at least the MOS8520, WD1770 and CPU) as a DIY kit, so I can assemble it myself?

Great work by the way! I have been thinking about an SMD board myself, but haven't found the time to design one.
(Have been busy drawing the schematics of the 1570 drive, including the modifications to the original 1571 board.)

 

[pazuzu72]

Thank you, standard 34 pin connector requires an amiga drive (or a modified pc drive), the flat connector instead a slim pc drive (obviously without any modification).
At the moment I can only send you a PCB if you need it, maybe a wd1770 but nothing more.

 

[MNM(tm)]

Ah, okay. I wasn't aware that the slim FDD already supplied the READY signal, but then again, I haven't had the time to do the proper research yet. ;-)
Would've been nice that your design already incorporated the READY signal circuitry, because there are way more standard PC FDD's available than Amiga drives.

Do you expect to have the MOS8520 and the CPU available again soon?

 

[pazuzu72]

Modding a pc drive is a matter of a couple of minutes. And at the same time if you want, you can use an amiga drive or use an adapter. You know I haven't really considered it? I saw it as the better solution.

I ordered 8520s but now their price is constantly increasing. I can't tell you when they will arrive.
CPUs are available from Mouser so they're not a problem.

 

[MNM(tm)]

I understand. I am more a plug-and-play kind of person, so my design would have the circuitry on board, which could be enabled or disabled via a jumper. ;-)
But hey, at least your design is finished and mine is still "under construction". LOL

Want would the price be for PCB + 8520 + WD1770 ?

Will you send me the BOM, so I can make an inventory of the components?
