Retro Chip Tester Professional (RCT) (English)

Zur deutschsprachigen Version dieser Seite!

The Retro Chip Tester (RCT) was developed to test „old“ memory chips from the 1970s and 1980s, which are often no longer recognized by today’s programming devices.

It is often recommended to use chips in the same device to test the functionality. It is forgotten that the rest of the hardware is also correspondingly old and frequent switching on and off can provoke further errors.

An ideal memory tester should of course recognize

  • Defective memory cells,
  • Timing errors due to material fatigue (e.g. with DRAMs), and
  • Incorrect signal levels due to material fatigue.

The Retro Chip Tester Professional is able to identify defective memory cells very reliably. A memory card can even be used to precisely determine the defective memory cells by storing the test results. In addition, the Retro Chip Tester has many other useful functions for repairing retro hardware.

The RCT can save the contents of ROMs, PROMs and EPROMs to a memory card. If the memory chip is known, the name is shown directly on the display. A database with 300,000 entries is available for this purpose.

For questions about the tester, I can be reached via the contact form.

If you are interested, I am happy to give you a board pre-assembled with the ATmega2560 at cost price (⇒contact form).

Video about the Retro Chip Tester Professional (Rev.1)

The Retro Chip Tester has now become very extensive in its functions. The video from beginning of 2021 still talks about 400 supported logic ICs, currently there are over 1200 ICs supported. The number of supported DRAMs and SRAMs as well as ROMs has also multiplied.

The following video shows the basic functions:

YouTube: Introduction Retro Chip Tester Professional Rev.1

In the meantime, the firmware has been significantly expanded. Among other things, the possibility of reading out protected PALs and GALs (under certain conditions) has been added. Even some exotic EPROMs can be programmed.

Examples for supported EPROMs and (P)ROMs

The firmware also allows the identification of countless (E)(P)ROMs (e.g. from Commodore, Sinclair and other manufacturers). The following chips, among others, are supported here:

(P)ROM: 2308, 2316, 2332, 2364, 23128, 23256, 23512, 231000/231001, 232000, 234000, 6540, 2513

bipolare (P)ROM: 7488, 188, 288, 187, 287, 387, S271, S371, 470, 471, S270, S370, 570, 571, 472, 473, 476, 477, 572, 573, S450, S451, 82S23, 82S123, 82S126, 82S129, 93426, 93427, K155PE23, HM-7648, HM-7649 (nicht getestet)

If you connect an inexpensive micro SD card adapter to the Retro Chip Tester, the contents of the memory chips can also be saved on an SD card. A binary file is created with the contents of the memory chip. If the ROM is known, a text file with the known information is also created.

SIMM/SIPP modules

30-pin SIMM and SIPP modules (via a simple adapter) can be tested.

Since the test is quite slow, only 256k x 8 (256 kByte) and 1024k x 8 (1 MByte) modules are currently supported. Memory modules with parity bit can be tested.

Also special IBM SIMMs with special pin assignment to identify the memory size can be tested.

Bipolar SRAMs 7481 und 7484

The bipolar SRAMs 7481 and 7484 (16 bit) can also be tested with the usage of an adapter.

The adapter for these chips is a little more complex, but it can be built inexpensively due to the simple components.

This memory is so small that it could be tested manually on a breadboard if necessary, but the Retro Chip Tester is much faster.

Multivibrators 74121,122,123 et al.

The RCT can also test multivibrators in such a way that the duration of the triggered impulse is checked. No „pseudo“ tests are performed.

ZIP RAM

Using an adapter you can also test ZIP RAM.

ZIP RAM was only manufactured for a short time and is e.g. been used in the Amiga 3000.

This memory can be tested in sizes 64k x 4, 256k x 1, 256k x 4, 1024k x 1 and 1024k x 4.

Intel 2107

With this adapter the Intel 2107 and compatible ICs such as MM5280 and TMS4060 can be tested.

 

MK4006/MK4008

The MK4006/MK4008 is a DRAM that is organized 1k x 1 and requires +5V and -12V as power supply. This memory can be tested with the help of the MK4006/MK4008 adapter (the MK4006 has not yet been tested).

 

EPROM CDP18U42

There are some adapters available for exotic ICs like the RCA CDP18U42 EPROM (256 x 8).

 

 

EPROM Intel 1702

With this adapter the Intel 1702 EPROM (256 x 8) or Intel 1602 PROM can be read.

A special feature of this memory chip is a supply voltage of +5V and -9V.

 

EPROMs MM4204/5204, ROM uPD454/464 and ROM 2513

Adapters for the National Semiconductor MM4208/MM5208 EPROM (512 x 8) and for the 2513 ROM (512 x 5) are also available.

A special feature of these memory chips is a supply voltage of +5V and -12V.

 

C64, VC20, VCS/2600 and MSX Cartridge Adapter

With these adapters, Commodore C64 cartridges (2x 8 kByte), VC20 Cartridges (up to 64 kByte), Atari VCS/2600 cartridges (2 kByte, 4 kByte and 8 kByte) and MSX Cartridges can be dumped.

 

 

Programming Adapter

Though the Retro Chip Tester is not a programmer, as a little extra it can program some EPROMs with the help of an inexpensive adapter. The EPROMs 2708, 2716, TMS2716, 2532, 2732 and 2564 are supported, which are no longer supported by current programming devices due to the high programming voltage.

Breakout Adapter

A breadboard or oscilloscope can be conveniently connected with the breakout adapter.

With the help of this 28 pol. adapter, both the chip and the output of the Tester can be easily contacted. The direct connection between the tester and the IC to be tested can be interrupted via jumpers.

Available Adapters for the RCT

Supported logic ICs (TTL and CMOS)

It is also possible to test over 1200 logic ICs. The following ICs are currently implemented (not all have been tested so far):

Supported PALs and GALs

The 20/24-pin ICs of the PAL and GAL families have a security bit which is supposed to prevent the chip from being copied. However, the underlying logic equations can be reconstructed with more or less effort if all possible input combinations are gone through and the associated outputs are logged and then analyzed. In this way a copy can be made that is logically identical to the original.

However, this approach does not work with the following ICs:

  • all „registered“ PALs (PAL16R4, PAL16R6, PAL16R8 etc.)
  • all GALs that have been configured as „registered“ (GAL16V8 etc.)

Basically only pure combinatorial logic ICs can be analyzed in this way. Purely combinatorial logic ICs that implement latches using combinatorial logic cannot be analyzed either.

Power supply

The tester offers the following options for power supply:

  1. With a DC/DC converter as a plug-in module. This module can then be used to test 4116/4108 chips. Power is supplied via USB or a barrel connector (6-9V).
  2. Without DC/DC converter, using a barrel connector (then a linear regulator must be fitted).
  3. Without DC/DC converter, via USB.
  4. The three supply voltages 5V, -5V and 12V can also be supplied from e.g. a PC power supply unit. 4116/4108 chips can also be tested in this way.

If no 4116/4108 DRAMs or 2704/2708 EPROMs are to be tested, you save a few more Euros by eliminating the DC/DC converter.

 

CPU NOP-Tester

The following PCBs are not part of the RCT. They are independent of the RCT and allow CPUs to be checked quickly and easily. Although it is not possible to completely test the CPU with a NOP-Tester, you can at least quickly check whether a CPU is still “starting”.

When inserted in a NOP-Tester, a CPU only executes NOP commands (No Operation). The lower address lines can be observed using eight LEDs. If the CPU executes the NOPs, the addresses should be permanently incremented.

There is more information about the CPU NOP-Testers here.
