You
are familiar with this MR413 produced by the former GDR based company RFT ? You
are right, this is a perfect copy of the early Texas Instruments Datachron aka TI-1790.
| Compare the perfection of the copy of the internals with the attached pictures. You'll find the MR413 always on the left side of the pictures. |
|
| The earlier MR411 from RFT uses the original Toshiba calculator chip, the MR413 uses a copy of it. |  |
