| 12 | 12 | It consisted of 25 keys and 8 LED digits, and was programmed in hex. |
| 13 | 13 | The Mikrolab is a Russian clone which appears to be almost completely identical. |

| 15 | TK85 seems to be the same as TK80, except is has a larger ROM. No |
| 16 | schematics etc are available. Thanks to 'Nama' who dumped the rom. |
| 17 | It has 25 keys, so a few aren't defined yet. |
| 18 | |
| 15 | 19 | When booted, the system begins at 0000 which is ROM. You need to change the |
| 16 | 20 | address to 8000 before entering a program. Here is a test to paste in: |
