Hi Craig

I'm highly impressed with the photos of the card cage. It looks entirely
appropriate. I shall enjoy putting it together and using it.

It's interesting to see your arrangement of the cards - where I still have
decisions to make about the 4k RAM and PROM positions. Details such as the
heatsink for the 7909 are good to know about.

I have a Tauntek 8080 in-circuit emulator which may be useful in the early
stages of bringing up the system (assuming I get to that point - also,
there are some limitations of the unit). Eventually, I'm hoping to be able
to make use of the I/O board for paper tape reading and writing - although
also aware of the limitations of this for data entry and storage. I realise
the importance of minicomputers and time-sharing for development via
cross-assemblers when the Intellecs were being put to use for engineering
tasks.

I received the USUS tracking number from Anchor - USPS
9405511206239389486502

Regards

Jon
