OT: not that classic but already old: Cubieboard2

by Holm Tiffe

Hi all, I've got 3 pcs. Cubieboard 2 SBC's with the Allwinner A20 SOC Chip on them. That's kind of a RaspberryPi SBC with an 2 Code Arm7hf on it. The boards are equipped with HDMI, USB, Ethernet (100Tx), SATA, SD Card slot and some 4G NAND Flash Cip on it. RAM is 1 Gbyte, CPU Clock is 996Mhz. Additionally I've bought some Base Boards for them, that's the DVK521 from Waveshare..contains the Baseboard, an Camera Module OV670, a 7" LCD with LVDS, a thermo sensor and other things.. Good HW in my eyes, but already outdated. I wnt to use the boards for some Home/house related stuff, PV, heating, Light control etc. and for that they should be more than enough. The Chips even have an graphics accelerator in the SOC. Now the Problem: as far as I know Allwinner has made some mistake using gnu/Linux stuff without any respecting the GPL. Because of that (if no other cause) most of the support Software on the net seems to be gone. There where some different Linux distributions for it, (Linaro, Cubieez etc) but most of the stuff isn't available anymore because of dead links. I've successfully build an modern Armbian image for them..but have endless trouble. The Xserver configutres an not existing Video Output, the LCD is unknown at all and if I manage to switch the X-server to the HDMI output using xrandr (only with tricks because it needs a session) the performance is like some old thick glue... Besides of that I had to fix an already for 8 years known Bug in the A20 Ethernet driver (it simpy has a more modern ethernet Unit as the A10 inside) that was'nt fixed at all. Armbian has only "community Support" fo those chips..which means that there is no support at all. If one asks for help the answer is more or less "find it yourself and provide a patch". I have an Linaro disk image that seems to be working, but there are some parts missing. The base distribution seems to be ubuntu 12.04 LTS (precise Pangolin) for armhf. I can't find a package repository anymore..(since that's long outdated). I've managed to install ssh by using an tarball of an ubuntu 12.04 armhf image for another board..and it works..but sshd is still missing. There are more modern disk images at https://mega.nz/folder/ZtwxCCJC#AIYHcTqz-ucjuzKnE9qD7A/folder/t0p2SBQD but mostly they don't even boot..possibly they using an newer/other uboot and uboot-envirnonment... Now the question: Is someone in the world still using those boards and has disk images/software for them? Again: I'ts not that much interesting that this is old linux, because I'll use that only inhouse in the lan, not browsing actual websites.. I'm a BSD guy and not know that much about Linux, especially such things as configurations for uboot etc. and there is none that I could ask for such things. Kind Regards, Holm -- Technik Service u.

Fwd: SBC6128

by Doug Jackson

Hi Dave, I'll send this to the group, I suspect my email made it into your spam. Doug ---------- Forwarded message --------- From: Doug Jackson <doug(a)doughq.com> Date: Tue, 14 Jan 2025, 6:05 am Subject: Re: SBC6128 To: <dave.g4ugm(a)gmail.com> Hi Dave, I was just researching the IOB6120 (I had an 8 at the end of the model.. sigh - memory is often faulty) WOW - I had no idea that existed. I also had no idea that the community picked up Bob's designs and ran with them so enthusiastically - I feel like I have been under a rock for quite a while. I would be very very happy to purchase your board + IOB that you have put together - If the enclosure is not ideal, I am very happy to update that - these little boards are awesome. Just let me know a Paypal address and shipping details.

New DRAM (SIMM) board works but gives a parity error, only on cold powerup

by Anders Gustafsson

Hi! I have been mostly lurking here, but I have been designing a DRAM board for the HP1000 A-Series, using a more modern 72-pin SIMM. The A400 can adress 32Mb of parity ram so I use 17 bits on a 64Mb SIMM. I have taken inspiration from the original HP12103X boards and tried to keep away from esoteric parts. The board prototype works now and passes all tests, except that it gives a partity error in one of the first addresses (ie 2,7,10 octal) when booted cold. If I then run a %T it works fine, and also if I reset by bringing PON low. I have tested with different SIMMs and the two different types I have tested both exhibit the same issue. The 64Mb one has Samsung KM41C16000C chips. As this is for hobby-use, it is not a big deal as the board works, otherwise, but it is annoying. If anyone here, and I expect there are several that have worked with DRAM chips, have any suggestions on this issue or the board in general? Schematic is here:www.dalton.ax/hp1000/Memory/HP1000RAM_SIMM_Buffers_20241130.pdf Yes. I have also written protocol decodes for the KingstWiz LA5032 32-bit LA to analyse the HP memory bus if anyone is interested. -- Med vänlig hälsning Anders Gustafsson, ingenjör

DECtalk for Digital UNIX

by Cameron Kaiser

Anyone out there collecting Digital UNIX or Tru64 stuff? I'm trying to find the Alpha version of DECtalk V4.2A that ran on Digital UNIX. The readme file is easy to find but not the actual package. If you know where it is or have a good guess, I'd be much obliged (and so will this AlphaPC 164LX running Tru64 5.1B). -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser(a)floodgap.com -- The surest test of discipline is its absence. -- Clara Barton --------------

Not Try Algol 68 on Windows

by Lyndon Nerenberg (VE7TFX/VE6BBM)

Could we maybe change the subject headers here? Neither Fortran nor IBM terminal controllers has anything to do with Algol :-)

Re: Try Algol 68 on Windows

by Paul McJones

This sounds like FLACC (Full Language Algol68 Checkout Compiler) by Chris Thomson and Colin Broughton: "You know, we only ever got 22 copies installed, and less than 5 of those in North America. Even though it ran on 370's under MVS, CMS and MTS, and was cheap and reliable. Talk about a marketing disaster.
