Introducing Proteus - a new prototyping board

Introducing Proteus - a new prototyping board.

While Proteus does have MORPHBUS, EXP1 and EXP2 headers so that you can add it to a Morpheus system, it is entirely usable on its own, or in conjunction with any other 4″x3.05″ Parallax mounting pattern prototyping board - for example ProtoBoard, ProtoBoard USB, SX, Stamp and other boards.

Look at the JPEG image below to see the top of the board.

Special features:

- MORPHBUS connector
- EXP1 & EXP2 connectors (labels are reversed, sorry)
- Unique layout to optimize 0.3″ and 0.6″ dip spacing
- Interleaved Vcc/Gnd bus (the zig-zag pads that are connected on top are Vcc, the ones on the bottom are GND)
- single row header support on the bottom of the board
- easy to configure for servo headers
- easy to mount 2×5 (or 2xN) headers
- area for voltage regulation above MORPHBUS header

Cost:

Bare PCB only: $12.95 USD (plus s/h)
PCB with two 1×10 female stacking headers and one 2×20 stacking header: $17.95 (plus s/h)

Available: NOW

Want 10ns SRAM? Use Mikronaut’s SOJ36DIP32 adapters!

Morpheus and Mem+ were designed to burst memory at 40MHz … and even higher. In order to do that, I needed to be able to use faster SRAM’s (ideally 10ns), so I designed a small SOJ36 to DIP32 adapter.

I was not going to announce it until I had it available for sale with fast memory surface mounted on it, but since people want to play with faster memory, I’ll sell bare PCB’s for it.

Allow me to introduce Mikronaut’s SOJ36DIP32 adapter - specifically made to allow use of fast SOJ36 SRAM’s on Morpheus, Mem+ and any other board that takes JDEC standard DIP32 memory!

$7.95 USD + S/H for a pack of four, $24.95 USD + S/H for a pack of sixteen, higher quantities available :-)

SOJ36DIP32 Adapter - use 10ns surface mount memory in DIP sockets!

Hi Guys!

I was finally able to find the time to clean up the XGA sources a bit and upload them! It still needs some work:

  • the SYNC and ADDR cogs need to be combined
  • needs to be modified to use a separate palette register per scan line
  • writing needs to use VSYNC period, and do more than one write per HSYNC
  • startup synchronization of the video cogs needs to be improved

but this will show you to write other video modes for Morpheus, and also how to use the bus and memory!

You can find it in the Drivers section of the Downloads page :-)
