Ron: I will post the RamBlade pinouts for RossH to see what is required. It should not be a major deal, but Catalina will NOT run without changes to the pinouts and Ram drivers. Note the I/O for the RamBlade is P23/22 NOT P31/30. You can use a propplug upside down on the bottom 4 pins.

1. What do I do with the zipped files (from my website www.cluso.bluemagic.biz )?· Unzip them to a folder on the pc. Format the microSD card with FAT16 and 32KB clusters (IIRC this is the default for 1GB & 2 GB cards). 1GB & 2GB cards are probably the best. I use SanDisk. Then just copy the files to the microSD.
2. How do I connect to the DemoBoard ?· At the beginning of this thread is a pinout for the various connections. Provided you have nothing in the prototype area, using the outer row of 12 pins on the RamBlade,·I suggest you solder the first 4 pins and the·last 2 pins with the pins facing down (i.e. solder the pins on the reverse side to nomal). This means you will have (from the top) 3, nc, O, I, and skip 6 pins (can be added later) and solder the last two as nc, G. You also need to solder a wire link joining the upper 2 pins of VR1 (see photo on page 1 of this thread). Now you can plug the RamBlade into the Deom Board. P0 will be the SO (serial out P22) on the RamBlade and an input on the Demo Board. P1 will be the SI (serial in P23) on the RamBlade and an output on the Demo Board. Later you may wish to also connect R, pI, pO for resetting and·programming the RamBlade but this should not be necessary.
If you do not understand my instructions, please ask.

Is this assuming any particular software is loaded on the Demo Board? Is the intent to use the USB connection to the Demo Board as the terminal interface?
You can use the Demo Board as a Terminal - will require terminal software either on OBEX or roll your own. Alternately you can use the USB and a PC. Soon you will also be able to use the 1-pin TV (works) and 1-pin PS2 keyboard as well.
The RamBlade software on uSD expects a terminal on P23/P22 at 115,200 baud. The eeprom software just boots from uSD, so this does not need to be changed (hopefully ever) - if it does, remember you must short the link labelled WE to enable writing to the eeprom.

Style and grace : Nil point
Here are photos of making the 1-pin TV (video) cable and the 1-pin PS2 Keyboard cable. The circuit and connections are described 2 posts above.
I have used old computer cables except for the RCA plug and the PS2 Keyboard (6pin) socket. Note if you have a USB keyboard that supports PS2 mode you can use a USB socket instead of the PS2 socket, although not all USB keyboards can do PS2 (they autodetect).
TV (composite video cable)
Original cable was a speaker cable. Also shown is the purchased RCA plug.
Solder a 100R onto the yellow wire. Also shown is yellow heatshrink.
Heatshrink fitted over the resistor and wire joint.
Resistor soldered to centre pin and black wire to outer pin if RCA plug.
Finished cable.
Keyboard cable (PS2 1-pin version)
I used an old computer CD cable. I cut the extra mounting clips off the 4-pin plug. My 4-pin plug had another set of finer cables connected to another smaller plug. I carefully cut those wires off.
A: The white wire has 100R soldered with yellow heatshrink covering the joint. The other end of the 100R is soldered to a 10K. A 10K is also soldered to the PS2 socket (clock pin) and then covered with heatshrink.
B: A larger piece of red heatshrink is ready to be placed over the 2 resistors.
C: Red heatshrink is fitted over the 100R & 10K resistors but not shrunk yet.
The resistors are then soldered to the PS2 socket (data pin) and the red heatshrink is slid over the joint and shrunk.
E: Next the black (GND) and red (+5V) wires are soldered to the PS2 socket.
F: The exposed leads from both the 10K resistors are then bent back ready to be soldered to the red wire/PS2 socket.
G: The 10K resistors are soldered to the red wire at the PS2 socket (+5V).
H: Completed cable.
Power cable (+5V regulated power pack)
The cable was made from an old power switch. The 5V supply is from an old camera charger (neither shown).
CPM in a matchbox·· Here is a photo of the RamBlade (SBC mode) in a matchbox. Propeller & 512KB SRAM on the pcb underside.
While I was out buying the connectors today, I saw a rollup keyboard. The keys were backit. It·was·USB & PS2 compatible with·a USB plug and came with a USB to PS2 adapter too.·Cost in the shop A$50 (about US$45). (Jaycar for the Aussies).

4-pin interface
power out (3V3 and GND)
2-pin I/O interface
circuit for 1-pin keyboard (resistors) & PS2 connector
a USB connector can be soldered instead of the PS2 for USB keyboards in PS2 mode (saves an adapter)
circuit for 1-pin TV (resistor) & RCA connector (B&W only)
DC input connector (for power pack 6V-9V DC or 5V regulated)
5V regulator & capacitors (not required for 5V regulated supply)
3V3 regulator & capacitors
Optional additional interface & circuitry for
full 2 pin PS2 keyboard
additional·3 resistors for full 4-pin TV (color)
If so, PCB only, or kit of parts?

BTW I could easily halve the size of the RamBlade using the smaller ram and prop packages with the uSD over the top. My point was to make a pcb to plug into other pcbs including the Prop Proto Board. But of course it can run standalone with the modified keyboard and video cables.

Got my Ramblades the other day... Now, I'm going to put one on my PSB accessory board and see what possibilities that opens up...
My first thought is to see if Beau's high speed serial link will allow me to us the Ramblade as a frame buffer, so as to do a better job showing a full-screen 6-bit image.
Right now, I can use an SD card as a frame buffer, but I have to drop the refresh rate down to 11 Hz, which causes noticeable flicker...
Second thought is to use the PSB as a terminal for the CP/M system they have going...
Yes, the terminal idea would be the first step and that is fairly simple.
For the framebuffer idea, yes Beau's code would be the best approach. I am presuming that it is sequential reads of the SD file, so the RamBlade could forward buffer 512KB into sram.

I think somebody has taken up the challenge on small computers. It will be a right B****** to fit a 15 pin to it though.

For me, the past is not over yet.
BTW I could easily halve the size of the RamBlade using the smaller ram and prop packages with the uSD over the top. My point was to make a pcb to plug into other pcbs including the Prop Proto Board. But of course it can run standalone with the modified keyboard and video cables.

With a blink-based character input and direct optic nerve output, CP/M could be run strait from the eyeball.
You would have to spend most of the day staring at the sun (not·so good, for half of the year, in your bit of the World)

My first thought is to see if Beau's high speed serial link will allow me to us the Ramblade as a frame buffer, so as to do a better job showing a full-screen 6-bit image.
Right now, I can use an SD card as a frame buffer, but I have to drop the refresh rate down to 11 Hz, which causes noticeable flicker...
Second thought is to use the PSB as a terminal for the CP/M system they have going...

Yes, the terminal idea would be the first step and that is fairly simple.
For the framebuffer idea, yes Beau's code would be the best approach. I am presuming that it is sequential reads of the SD file, so the RamBlade could forward buffer 512KB into sram.
