RCT Pro – New firmware v.27 released

There are many improvements:

1. The ROM identification feature has been improved. Instead of
displaying the first database entry only, it shows all entries for a
calculated CRC32 now.
2. The max. number of entries for the Index Compiler has been increased
to 1,000,000
3. ROM dumping of VCS Cartridges supports F6SC and F8SC bank switching
4. some minor optimizations

A bug that nobody complained about has been fixed:
– The orphaned text “Search” in the help line for the “SERVICE” menu has
been removed

A few exotic memory ICs have been added:
– DM85S68 (16 x 4, SRAM)
– HN62312 (256k x 8, ROM)
– TMM2332, Ro9333, Ro9433, CDM5333, 2333 (4k x 8, PROM)
– Atari 23128 Cartridge ROMs (16k x 8, ROM)
The Atari “23128” is not a real 23128, it is a modified ROM with 24 pins
that is used in cartridges and has a build in bank switching. So you can
dump these ROMs without using the VCS Cartridge Adapter.

New and improved Logic-IC tests:
– 75361 (DIP-8 and DIP-14), DM9000, DM9001, 74381, 74382 added
– 74259, 74381/74382 renamed to 74F381/74F382 (improved/corrected)

The 75361 seems to exist as DIP-8 and DIP-14, you can select DIP-8 and
DIP-14 from the menu.

New beta firmware v.27beta4 released

After the major update regarding the ROM identification/testing feature
in v.26beta2 that seems to be stable, some logic IC definitions have
been improved and added.

Following the major update of the ROM identification/testing feature in
v.26beta2, which seems to be stable, some logic IC definitions have been
improved and added, e.g. DM9000, DM9001, 74259, 74381/74382 renamed to
74F381/74F382, 74381, 74382.

Also a strange IC has been added. The 75361 seems to exist as DIP-8 and
DIP-14, so you can select a DIP-8 and a DIP-14 from the menu now.

This will probably be the last beta version before the release of v.27.

We updated several sub routines to speed up
writing on SD card. Since this changes some code I add another testing
cycle for this firmware release.

RCT Pro – New firmware v.26 released

We are proud to present a new firmware release (v.26) after two beta versions.

„Joystick test“ (logic menu). Requires a simple adapter with DSUB-9 socket.

New Adapters
Joystick Adapter (a small adapter that allows to check the functionality of a standard joystick).
Intel 1101 (SRAM, 256 x 1)
The Gerber data for the current version of the adapter has already been published. The schematics of all adapters are available in the BOM.pdf now.

New Memory ICs supported
Intel 1101 and compatible (adapter required with custom definition, 256 x 1, SRAM)
DM85S86 (256 x 1, SRAM)
New Logic ICs supported
