Subject: RE: CGN boards


I have a couple of the CGN wire wrap modules.  I have two versions. One 
is the single chip version, the other is the expanded version. All of 
the pins from the CPU are extended via wirewrap pins. Everything is 
aligned on .1" centers, so you can insert the module right into a 
standard perfboard. After having tinkered with this stuff for the past 
10 years, I have to admit the CGN wire wrap module is about the coolest 
ideas I have seen.

While I think everyone should do a complete wire wrap CPU at least 
once, just for the sense of accomplishment, it gets pretty old once you 
have done 5 or 10 of them. The CGN module is the basic CPU circuit 
prebuilt, and ready for wirewrap. Its really a time saver. The modules 
run from $19 to $38. Since it takes me about 4-5 hours to build one 
from scratch, I find it cheap.

I am not aware of a version that actually has the RAM built in, though 
they may have one. They have several options, including a MAX232, 
external memory latches, etc.

You also might consider one of Peter Dunsters 'F1 boards. Personally, I 
don't need all of the motor driver stuff on the daughter board, but the 
'F1 gives you expanded memory without loosing any of the I/O ports.

Now that I have said all that, I don't have CGN phone or address here.  
The address is 1000 Chula Vista Terrace, <somewhere> CA <some zipcode>, 
but that don't help much.

| Hi all;
|
| 	Does anyone have a CGN board? Do you like it? Do you have
| their phone number?
|
| 	I understand the board kit comes with a 6811, 32k RAM, a
| christal and the latches. I also understand it has wire wrap pins
| that connect to the 6811. Do I understand this correctly? What
| else is on the board? What is the part number for the kit?
| How much is it?
|
| 	I love my miniboards, but I need more memory. Thanks for
| your help.
