S-100 RAM Cards |

I have gotten more confident with my ability to
conclusively test various s-100 RAM cards, allocate programs to specific locations, change memory values, etc using my IMSAI. I can also assign the memory pages (0000-1000, 1000-2000, etc.) so that there can be more than one RAM card installed without conflict. I have installed 32K into the IMSAI. As I identify good RAM cards, I can put some into the SOL-20 I also have on the table. I have a small pile or RAM cards that I have accumulated from various places. I also soldered up a cassette cable for the IMSAI. I broke down and bought a new Radio Shack tape recorder so that I can count on a reliable drive when testing cassettes on an S-100 system. I have some Altair BASIC tapes that I want to load. After that I plan to attempt a Micropolis controller card and 2 or 3 compatible disk drive. The Micropolis cards had their own monitor I believe. Overall, I am working at being a competent S-100 programmer, and hardware support person (but not hardware developer) Reply |
