PropCade is a self-contained, affordable Propeller platform for:

• writing Spin and Pasm code right on the Propeller with Sphinx
• emulating old computers (Z80, 6809, etc)
• emulating old game consoles
• making arcade cabinets
• serial terminal replacement
• running virtual machines (ZOG, Java and others)
• running FemtoBasic
• VT100 replacement

The possibilities are endless!

Sapieha PCB layout is amazing – this board was designed for 100Mhz+ operation!

Kit #1 – “PropCade 128″

PropCade PCB, *COMPLETE* kit with 128KB SRAM for $109+s/h

Complete means complete – the only empty sockets on the board will be two of the 8 pin dip memory expansion sockets – please see the feature list at the top for what is included.

Add $30 if you would like your PropCade assembled and tested.

Kit #2 – “PropCade Essentials”

PropCade Essentials kit for $39 + s/h

Since a lot of Propeller enthusiasts will already have most of the parts needed to populate PropCade, I thought it would be useful to make a “Bare Kit” consisting only of the parts that are not readily available from DigiKey.

This kit includes ONLY the following parts:

• PropCade printed circuit board
• 6.25Mhz crystal
• uSD socket
• power switch
• triple RCA socket that PropCade is designed to accept
• two of the RJ45 unshielded connectors I use

You will have to supply all of the other parts.

Shipping and handling should be between $28-$35 for XpressPost, and $17-$25 for Expedited Parcel (best guesses, more outside US/Canada) to the continental U.S. including tracking and delivery in 3-5 business days to major urban centers. Please send me your exact address for an accurate shipping quote.

Here is an example of a PropCade complete kit 128K

• XpressPost shipping to California: $28 s/h, includes tracking, 3-4 business day delivery
• Expedited Parcel shipping to California: $17 s/h, includes tracking, 4 business day delivery
