Checking the status of the Zip drive
TIP.EXE is a Zip disk surface quality test. The principle of the program is as follows: this program reads each sector of data from the disk, enters them into the…

SPD EEPROM: Functioning Algorithm
With the advent of the new SDRAM standard, a new I2C interface has also appeared. The interface was developed by Philips and is used as an internal auxiliary bus of…

Excellent coprocessor (FPU)

This time it turned out with a floating point. In time, apparently, they lured the team of Dirk Meyer, one of the creators of Alpha 21264. Now the floating point computation unit contains three separate blocks: addition (FADD), multiplication (FMUL) and storage (FSTORE) (see Fig. 1).

The addition and multiplication blocks are fully pipelined. The FPU architecture is such that it can take every clock input: one addition instruction and one multiplication instruction. Continue reading

Golden Disks and IDE
The problem of recording "golden" discs has already been covered on our website (as well as in the journal CHIP, No. 8, 1999). However, the problems continue. Only, if earlier…

Our tips
Tip 1 Turn on the Zip drive only for the duration of discarding information with constant monitoring of its operation, so that when clicks appear, inspect the drive in a…

DIMM EEPROM test program dimm.exe
A quick analysis of the type of DIMM module installed in the system unit can also be done with dimm_id.exe. The program is subject to all the restrictions discussed above:…
