Use these adapters with the „ZIP16“ or „ZIP20“ menu entries.

Use this adapter with the corresponding menu entry „2107 – 2107 Adapter“ (available in v.20beta4 and above).

Don’t use it with the „2107(!) – Vcc:11 Vdd:18 Vbb:01“ menu entry (firmware v.20beta4 and below), it might destroy the adapter. There is no danger for the RCT or the memory IC when the wrong entry is used.

Download MCM6605 Adapter

Use this adapter with the corresponding menu entry „6605 – 6605 Adapter“ (available in v.24beta5 and above).

TMS4050 has been tested. TMS4051 is still untested. Any feedback is highly appreciated.

Use these adapters with the standard menu entries for DRAMs. The adapter converts the ZIP pin assignment to standard DIP pin assignment. Don’t use the „ZIP16“ or „ZIP20“ menu entries with these adapters.

This adapter allows testing an Intel 1101 in conjunction with the Custom Definition for this IC.

Seems to work quite fine. Any feedback is highly appreciated.

This adapter applies +5V at Vpp, so these EPROMs can be realiable dumped. Only required when a 2716/2532 requires a higher current at Vpp (see manual). Alternatively, a simple intermediate socket can be used. This adapter can also be used with other testers.

You can also use a custom definition file, the EPROM is inserted rotated 180 degrees and so Vpp can be connected to Vcc. When you use the custom file the adapter is not required.

This adapter allows reading a MK28000 or TMS4800 ROM in conjunction with the Custom Definition for this IC.

This adapter can be used to dump 16bit EPROMs with 1-16 MBit size.

This adapter allows programming of 2708 EPROMs.

Note: The adapter is not required when you want to dump 2708 EPROMs.

This adapter allows programming of 2716 and 2532 EPROMs.

Note: The adapter is not required when you want to dump 2716 or 2532 EPROMs.

This adapter allows programming of TMS2716 EPROMs.

Note: The adapter is not required when you want to dump TMS2716 EPROMs.

This adapter allows programming of 2732 EPROMs.

Note: The adapter is not required when you want to dump 2732 EPROMs.

This adapter allows programming of 2564 EPROMs.

Note: The adapter is not required when you want to dump 2564 EPROMs.

This adapter adds non-overlapping and quadrature clock signals to the built-in simple clock generator.

From hardware rev.1.2k the Decoupling Adapter is not longer required. It might still be useful when an case is used. It can also be used with other testers.

This adapter is usually not required. It is used when someone needs an increased ZIF socket due to a housing.

Use this Adapter to „dump“ a 20-pin PAL (such as PAL16L8) using the 27C020 EPROM setting in your RCT. You need also the software from Charles MacDonald to convert the dump into a PLD file.
