Reports about the RCT
RCT helps repairing an Apple I
BasicGallery, the historical archive of BasicNet, switched on the Apple-I on Friday, October 15th, after replacing two non-working components. Marco Boglione acquired the Apple I at a Christie’s auction in 2010 for 157,245 euros.
Marco Boglione is an Italian entrepreneur and the founder and president of BasicNet, which includes the brands Kappa, Robe di Kappa, K-Way, Superga, Jesus Jeans, Briko and Sebago. The computer exhibition is located in Turin, on the first floor of BasicVillage, the headquarters of BasicNet.
RCT on YouTube
I am pleased about the many positive reports on YouTube:
- Noel’s Retro Lab: The Ultimate Retro Chip Tester? (English)
- Nils Retro Hobby Room: Let’s Build the Retro Chip Tester from the 8Bit Museum (English)
- Redled: Retro Chip Tester Professional (4 Videos, over 12 hours, German)
- Nagy Attila AT-Vlog: RetrĂł Chip Teszter (Hungarian)
- ShadowTron Blog: Retro Chip Tester (8 Videos, over 2 hours, English)
A playlist with all reports can be found here.
RCT programs 2708 EPROMs
The RCT can now also program the EPROM 2708. This requires a simple, inexpensive adapter that provides the programming voltage. This feature is currently classified as experimental and I would appreciate your feedback on it.
Detection of Page Mode and Static Column Mode for DRAMs
- The full version of the used firmware is displayed in the Info menu (e.g. v20B5, when a „beta 5“ is used).
- Logic menu: The 100-step jumps after a while have been reduced to 20-step jumps.
Use the adapter only(!) with the corresponding menu item „2107 – 2107 Adapter“ from firmware v.20. Otherwise the adapter can be destroyed. However, there is no danger to the RCT or the memory IC. The „old“ entry for direct testing of 2107 ICs has been removed.
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 Display Driver for OLEDs
The display driver has been optimized again for OLEDs. Now OLEDs should also work reliably with the WS0010 controller (e.g. from Newheaven). If problems arise anyway, only a small modification of the display will reliably help (see manual).
New Hardware Version
Based on suggestions, I have modified the board a little. In rev.1.2k („j“ was skipped due to the similarity to „i“) the following ideas have been included:
- There is a fourth button (it corresponds to pressing SELECT/JUMP at the same time to jump back one menu level).
- The decoupling Adapter was integrated on the board, i.e. there are now jumpers next to the ZIF socket.
The fourth button is not absolutely necessary, but makes operation maybe a little more convenient. It can also be retrofitted to all boards (see sec. „Tweaks“ in the manual). Whoever packs the tester in a housing will probably continue to use the Decoupling Adapter and not assemble the jumpers.
New Logic ICs supported in v.20
New Custom Definition Files
There are new definition files for special memory modules.
The manuals have been updated and can be downloaded from my website.
The interactive IC comparison list has also been updated, as have the PDFs with the supported ICs.
