Not sure if you saw my original reply on the other thread before I removed it? What I said was basically...
I can read bytes from the sram at the same speed as from hub. However, writes are slower, and of course words and longs are slower again.
Ram requires A0-18 (for 512KB) + D0-7 + either -WE & -CE or -WE & -OE. I tied -OE to gnd. If you do not do this then there will be bus contention on the data lines. So, for 512KB, non-latched, requires 29 prop pins. I use one for the microSD -CS (the rest share common pins), so that makes 30 pins.
Two more for serial I/O or 1-pin video (monochrome TV 80x24/25 works on LCD TV)·& 1-pin keyboard (PS2) for SBC.
Using latches slows the access even further.

Yes, I was thinking a separate -CS on uSD would be necessary in your design ... I never checked your implementation. Yes, latches are annoying, but there is a place for that too ... everything is a trade-off when dealing with constraints. I've always liked puzzles though.
I'm sure your board will bring much hobby joy. Best of luck.
I have just sent out parts kits to a few who are capable of assembling them for testing. I have included 6.5MHz (104MHz)·xtals as standard (they also have the xtal socket pins attached so don't miss them!) Also are 2 xtals, 1 x 7.3728MHz (~118MHz)·and 1 x 13.5MHz (108MHz) for testing.
Note U3 was incorrectly ordered so it is SC70 instead of a SOT23. You will need to spread the outer 4 legs slightly to avoid shorts.
Where am I up to? Well, I had a power short on the SDA pin which caused the eeprom to fail the write test. It also causes the ram to fail the test. I have removed the short, but either the prop or eeprom has suffered a failure. · I soldered these at night on my boat where I do not have the best of tools for smt.
I am hoping to return to Gosford later this week at which time I can get my son to solder up a batch of boards for sale. I will email those who have ordered shortly.

Bovril USED to be great. It used to be beef extract. From real cows. Now it's made out of yeast and is hardly distinguishable from Marmite. I guess the real stuff was killed of from fear of mad cow disease.

For me, the past is not over yet.
My RamBlade has now been fully tested... Ram, microSD, eeprom
I am just debugging the drivers for ZiCog. It is partially booting.
Debugging is a bit of a pain as compiling and downloading has to be done on·seperate pins to the serial interface once booted. This is because I have optimised the ram for speed, so the download pins are shared with the ram data bus.

Notes:
1. RN1 & RN2 footprints are extremely small. You will need to meter them after soldering.

3. X1 has 2 socket pins that allows the xtal to be replaced.

Toby: Well it will fit into 2 (end to end) DB25 to RJ45 backshells
The current pcb is 0.2" wider and 0.1" longer than it needed to be. I did this because of the various connector options I added to J1 for flexibility.
To get a feel for the size, I have them in panels of 10 which measures 3.8"x6.5". So 5 pcbs fit into less size than the Prop ProtoBoard (well 2x2.5 pcbs).
I did toy with doing 1 pcb for myself at half the size. However, I cannot get the ground planes right for overclocking. I can of course use 4 layer but I still cannot get the decoupling correct. I did find a microSD conector that places the uSD card over the top of the chips. Since the connectors take up more cubic (3D) space than the pcb, pin-stake connectors are required.
I am really pleased with the ground/power planes and decoupling for the prop. Maybe this afternoon I will get a chance to try some overclocking
Tonight I collect the assembled pcbs from my son.
BTW There are no pcb errors other than the resistor network pads could have been larger for hand soldering. U3 footprint is incorrect due to me purchasing the wrong footprint part.
To Do (before I can ship)...
1. Finish the eeprom bootloader code
2. Incorporate the latest ZiCog instruction emulation additions from Drac
3. Build a new set of files for the SD card (including CPM3 and Dracs Xmodem)
To Do (later)...
4. Get 1 pin Keyboard working

Cluso, got my first one up and running. Had a minor issue the tantalums (could have been installed backwards - isn't the bar positive? Not clear as it has a black square in the middle that may indicate negative)
Apart from the tants the only thing I had to look up was the orientation of the U3 gate IC - perhaps you could add that to your list for others doing self assembly. Couldn't quite tell from your photos!
All quite exciting... look forward to getting a uSD or image thereof to really start playing
Tantalums: The white bar with black square is +ve on the tantalum and the bar is marked on the pcb closer to one pad.
U3 pin 1 is closest to the "U" of "U3" overlay. i.e. the "U3" is the correct way up.
U4 has the indent on the chip outline. The legend "U4" is the correct way up but is at the bottom of the IC (closest to pins 4 & 5).
Attached is a program to check the ram, uSD and serial I/O. You will need to recompile with the correct xtal setting (I am currently using 5MHz). It will also be necessary to remove the propplug once the code is downloaded to hub ram and connect to the serial I/O on P23/22 (you can use a propplug upside down to the lower section of J1). The code has an inbuilt delay of·25 seconds to swap serial ports over - you must do this as you will have a conflict with the propplug download pins P31/30.
It does not check the eeprom as this can be tested simply by the propplug and proptool. You can however, download this program into the eeprom and it will spring to life on powerup if all is good after the 25 second delay on the new serial port.

I had installed the prop tantalum backwards - forgot the copper pour is +ve in that area. The bars closer to one pad are a better guide!

For me, the past is not over yet.
I have some posted info about the board. I will leave heater to the software section.
Must update my website - time!!
Tubular: Here is the latest ZiCog code for the RamBlade.
Update: Here are SD files required. The RamBlade code will have to be modified for the change in filenames (done in version _rr141 now posted)·I suspect a problem with the RamBlade driver code and am tracking it down.

Check out our $25 SMT Stencils!!!
www.ohararp.com/Stencils.html
My son has done a nice job without a stencil (must have been the instructor LOL). I am not sending them out as kits, except a few to get some testing done.
Thanks for the kind offer. I have just bookmarked your website for future reference. I am sure there is other interest here also.
