NEW KEYPUNCH INTERFACE DEVELOPMENT
Did more work on the PC side program for my round of enhancements, most of which support card images used with the IBM 1130 Simulator. I haven't worked out a 'ruler' capability that satisfies me, which would make it easy to determine the exact card column in which each character on screen will be punched.
QUICK BUILD OF BRIAN'S CARD READER INTERFACE
I had the interface about 85% wired by mid-afternoon, although I still need one socket (for the 28 pin SX28A microcontroller) as I don't want to directly solder the chip onto the board. The major remaining wiring is the connection of the leads I installed that connect to the Documation card reader cable - just a matter of stripping the ends and soldering them onto the physical connector board I have inside my 1130 replica card reader controller enclosure.
I proceeded to verify the lack of short circuits, the correctness of connections, scanned for any missing links, and prepared a mounting location for the interface I build inside the enclosure. Once I received the last socket in the early evening, I soldered it in,
I had a party to attend at night, but was almost completely done wiring it into the enclosure. I could be ready for power up test and programming of the microcontroller on Sunday morning after just a few final connections and checks.
DATACENTER SHED CONSTRUCTION
I used a 2x4 and a hydraulic jack to push the shed into correct alignment, then retightened all the screws I had loosened for the upper portion. It bent back partway, so not yet good enough, but the problem is down to about 20% of the magnitude of the original problem. I will continue battling until it is reasonably close.
