I've been making a debugging ROM board to test out the various
parts of the KIM-1. It is based on taking over the KIM at reset
and running test.
So far I've got two test working. One is a basic, is it running test
that just blinks a light on the debug board.
The next is a test of the first 1K of RAM.
A little tricky to do without RAM.
I expect to write some more for the RRIOT ics.
If anyone has interest, they can follow me on the Vintage
Computer Forum or contact me here.
The board has 3 ttl ICs, a 2764/27128 EPROM, a couple
LEDs and a dip switch. Also a few pullup resistors and capacitors.

Dwight,
That is a pretty cool project. May I suggest you break it out on VCF into
its own thread so people can more easily follow what is going on? For those
interested in the original thread:

I still need to post the final schematic. A new thread might be a good
idea.
I wanted to keep the board as simple as possible so one could just
wire wrap or point to point it.
It only has a 7474, 7402 and a 7404 as well as the EPROM.
It could easily be done with a GAL or PAL and the EPROM.
I think two schematics showing each would be best.

I've started a new thread.
See:
http://www.vcfed.org/forum/showthread.php?54850-Debugging-a-KIM-1-computer
I've created a simple debugging board that one can plug onto the KIM's expansion
buss that has debug code on it. It allows one to find out what is failing on the KIM so
they know what to replace.
While developing it, I found that my 6530-002 is bad. As we all know, these are custom
made and no longer available. There is a similar part, the 6532 that is similar, without
ROM.
It can be used with an adapter. I've reviewed both specifications and believe I've
figured out how to do it. Others have made them that are configured for the Gottlieb
pinball machines but they will not work for the KIM because the KIM selects are configured
differently.
I've begun making a hand wired adapter with a EEPROM. This will be in a stacked socket
under the 6532. I expect to use the debug board to program it in place.
After verifying that every thing works, I may create PC boards for the debug and 6532
adapter.
I know there are a number of dead KIM-1s out there.
I'm looking to see how many people would be interested in buying a set of boards?
I'm thinking in the range of $10 to $20 someplace, depending on volume. I expect to
have two small boards for each adapter and one for the debug board. I'll most likely
have them made as a set to save cost.
I can populate the adapter boards with the SOIC parts and leave the rest to the person
buying the boards.
Please let me know how many people would be interested??

Actually it'll use a EEPROM for the 6530 emulator. I've located
some small 28C64s. The advantage is that these can be programmed
with the debug board while on the KIM board. It should look good as
well because it will be tucked under the 6532. The registers are slightly
different on the 6530 and 6532 but they should work the same if one
ties the 6532s A4 a constant high. This looses half the 6532s 128 bytes
of RAM but the 6530 only had 64 bytes anyway so nothing really lost.
The only difference then is the interrupt. The 6532 has edge or level
interrupt but few people wire up the interrupt. It isn't clear but I believe
the 6530 is a level interrupt and that should be the reset level for the
6532.
I'm looking at board maker options.

I'd be interested, though I'd prefer something that was a drop-in replacement.
I'd be willing to pay additional for that.

This will be about as close to drop in as one can get.
The adapter will hide under the 6532 with very little hanging
out the sides. Unlike the adapter for the Gottlieb pins.
It'll be about 1/3 taller other than originally.
I doubt you'll find any originals, other than on another KIM-1.
