Minor changes, mostly cosmetic but I am print= ing a new set. If you want two sets you can have this version also.

Basically the patch i mention= ed when i sent the adapter board is built into another revision. It has been= do long since i did that, I don=E2=80=99t remember if I found any problems w= ith it or not. Basically, I got tired of programming 1702s when writing firm= ware

The adapter board plug= s onto the test pins that I brought to the edge. Not authentic, but one coul= d argue it is what Intel would have wanted if the EPROM were available. If I= ever release these intellect boards, I was not planning to release this alt= ernate purpose or the adapter. If you don=E2=80=99t have the schemati= cs for this version of the PROM board I can send them over so you can see ho= w it works.

The last c= ouple of slots do not have sockets installed, so I just use them for card st= orage. It is the 8080 cpu board.

Let me know if you are sending any parts my way for forwar= ding.

Hi Craig

I don't see prob= lems with the card guides. The result looks fine for my purposes.

I'm intrigued with the 2732 adapter providing a single-chip s= olution to the PROM board - and clear for access. I shall be interested to s= ee details when you are ready (just to mention you included one of these in t= he box with the other parts).

It seems unclear whic= h card you have in the last slot - I assume not the I/O board as I don't see= the pins of ribbon cable connectors.

I have looked= at my IPB - the caps (on the power rails) are 22uF 15v 10% with Kemet brand= ing - so a different part, although visually similar. No additional clues.

I have started to look at the Anchor price list - it= would be good to be able to fill some of the remaining gaps if they have th= e parts.

Regards

Fits OK, but correcting a few minor mistakes and then will print a set for y= ou.
