oldest 41c???

[Geoff Quickfall]

Wow, you had money at 17! :-)

Mine is Spring of 1980 and the board still works but the has been replaced with a CL board. The CL now contains my 600 Line program complete with synthetics that I wrote in 1984. The cards that hold the code worked flawlessly when I loaded the program to the CL and now is saved to flash. This 41c tall keys (with charger contact balls) was expanded to CX status minus the clock and finally replaced by a 41CX in 85. I do have a 7922Axxxxx but that came much later.

The CX effectively replaced the 8088 PC we had at the lab (with two 5mb stacked hard drive!) in 84 as well as run some lab equipment via HPIL. Still have both but installed the CL the 41C and use it at work.



Line 042 is PRTON from the IR Print module. The HPIL TO INKJET was used therefore XROM 29,33 as the 'BLINKY' module was removed to print the code with the HPIL PRINTER. You can see some simple synthetics at lines 14, 16, 68, 219, 226 but I cheated and used the ZENGRANGE ROM image from the CL board and not the byte jumper of old.

PS the labelling on the blank overlay is done as follows:

1. Create a file on word processor of choice.
2. Set font 9 or whatever works for your eyes and the blank overlay fields.
3. Format, space and print until labels correctly spaced on blank paper.
4. Once happy, print on laser/inkjet clear label stock.
5. Slice with ruler and blade to fit lengthwise in the blank rows
   

Certainly easier then the Letraset we used in days of old.
