Yesterday i was invented to a old stock clearance of a nearby university. They had masses of electronics and measure quippment and some old computers. I paid too much for a car full of "old garbage" but i was very pleased to finaly find a Basis apple clone there in good condition.
This clone has a heavy weight german tank style case with EMI protection. It works very well with one exception: I cant activate the 80 char mode. There must be an incompatibility. I have a bad copy of the Base manual, but it refers to the original roms. The 80 Column problem could be solved with the cards made specifically for the II and II Plus.
I am not sure where you could find original ROMs for this. I will be going through my website information later today. I remember a site that had this type of clone listed. Speedy may know something. I am jealous. I had one of these aluminum bodied monsters back in the day, although I don't recall where I got it.
The Z80 "looked" like a Microsoft Softcard, as I recall. The Cherry keyboard was sublime Sorry for necro-posting in my first message, but I have two questions about the Basis on picture:. Where do the additional white DB25 connectors lead? I can't see any expansion cards, perhaps they were unplugged and outside of the picture. Of course it goes both for serial, parallel and disk controllers.
Which diagnostic software was used, or which one would be recommended to check the configuration? I believe the unknown card in slot 1 should be the internal RS, but based on what I could find on the Internet, few or no Apple ][ applications recognize or can use it.
I tried a few ways to get some action from the serial port on mybut didn't get any meaningful results. It appears mine is unusually fitted with two half height floppy drives instead of two full height ones. It means a huge chunk of empty space inside, to the point that I've toyed with the idea to install some Nano-ITX board or a Pi?
You have to consider the meaning of 'compatible'. The Basis has pretty good compatibility to 48k Apple II Software. But if you wanted to use the full k or the advanced Serial, Parallel and Video features, you had to use specially designed Software or a patched Apple DOS. There are serious problems with later Versions of ProDos and auto-patch Hardware would not work in some cases as well. I have yet to get my BASIS to work properly one of the ROMS seems to be corrupt.
Although i did not collect material related only to Basis The utilities for use of the parallel and serial interface and the utility for switching the memory banks this was quite similar structured like the kB Saturn Ram Disk card, and the "preboot" for the next disk - if you wanted to boot CPM You can boot CPM without that preboot Thanks for the replies! In my case, I haven't found any stash of ROMs inside the computer. I understand now that it technically has a lot of add-ons built in, but none that is addressed in the same way that equivalent add-ons otherwise would be used, thus all the patching you refer to.
That is a shame. Even if someone that had the original ROM, they could copy them, since original Copyright Hold would most likely not care anymore and then you could restore the machine to its original state. Oh, I completely missed that auction lot.
I hope it went to a good buyer. Hello to all that have a Basis "tank"! This current offer is really a precious "gimmick" to those guys I have a Basis and thankfully have a keyboard. Beautiful machine but I don't think I've attempted to turn it on yet as I had no software. This is great. There are pinouts of the connectors included in the manual, as well as a schematic of the keyboard controller in the last pages.
There should be a connector on the mainboard that is Apple II compatible. In the early 's, I wrote numerous technical articles for the monthly newsletter of "BUGS", the Basis User's Group of Sacramento CA. Out of the box, the machine had 64K of RAM. It had just enough code to boot a floppy drive.
Booting a 5" floppy called the "Basis Booter" wouuld load a modified version of Applesoft Basic into the top 16K of RAM and lock the ram range to emulate ROMs. The "booter" disk was created by a special utility that read a standard Apple 3. The net result of this process was the equivalent of a 48K Appple ][ with an enhanced version of AppleSoft Basic.
Basis Basic called FP8O supported several additional keywords beyond Applesoft. PR 1 Accessed the built-in parallel card, while "PR 9" accessed the buiilt-in serial port. Commercial Apple programs that accessed the ports at the hardware register level such as "Print Shop" or modem comms programs would find both devices in "Slot 1". FP80 also supported accessing the functiion keys across the top of the keyboard.
The Basis built-in column display paralleled the memory space of the Apple column display with 2K of static RAM. The Basis monitor under FP80 would bank-switch, with the odd columns in the main memory and the even columns in the second bank. Because no Apple-centric software written for 80 columns knew how to address this scheme, nearly everyone I know also had a Chinese-knock-off of a Videx column card in slot 3.
By inserting a full set of six Apple ][ ROMs or EPROM copiesyou could free the full 64K of RAM for programs. Or you could burn the Basis FP80 to the eproms instead. The sockets on the motherboard were actually pinned out for eproms. By the time the Basis clone arrived inall the Taiwanese and Japanese-made floppies were capable of 40 tracks.
The Basis "zapped" versions of DOS 3. There was a Basis-provided floppy formatting tool that could do either 40 tracks, or 35 if you needed disks that could exchange with Apple users. Later on, the Basis Users Group developed a modified track version of ProDOS.
With ProDOS working on thea modified version of AppleWorks followed. All of these were technically copy-right-violating derivitives of Apple OSes. By the way, there were two generations of the Basis The "A3" had a parallel keyboard interface simlar to the one on an Apple ][.
The "A4" had a serial keyboard interface. It wasn't obvious since both vesions used a DB connector for the keyboard. The A3 keyboards had black keytops. The A4 serial ones had tan keytops. I burned many copies of modified keyboard PROMs to map the common Apple cursor diamond to the cursor pad keys on the Basis keyboard.
And to remap common WordStar keystrokes to the function keys. I always wanted a BASIS They were one of the coolest clones. Unfortunately I never got one, and now they are hard to find and expensive, so I probably never will. I'm sure there are many people who would be interested in seeing the ROM images.
If you could post them to the file library here, that would be wonderful, or if you'd prefer to email them, I could post them for you. Go to:. The six binary files in this zip file recreate "double-decker" firmware ROMs or EPROMs for the Basis The six pin sockets near the front of the motherboard originally held a single 2K eprom in the "D0" position.
This provided the ability to boot a floppy drive, or enter the Basis version of the Apple "monitor" with the classic Apple "CALL " command. There was no BASIC interpreter on board. Or, if you are a truly hard-core historic hardware enthusiast, the "Integer Basic" ROMs of the original non-Plus Apple ][. FP80 added keywords to Applesoft BASIC. The command "FP80" activates the column display mode. The most-significant-bit address line of a is brought out to the 6-pin header "J10", just to the right of the sockets.
The 2x3 six-pin header has. By connecting a single-pole double-throw toggle switch to this header, you can select either the lower half or the upper half of eproms. Just power-off, flip the toggle switch and power back on to switch modes. The files are straight binary images of the ROMs not Intel hex files that nearly any EPROM programmer can read. Use any flavor ofA, 27C32, etc with an access speed of nS or better. Once programmed, all of them are READ during operation with the same voltages and are essentially identical.
Since these ROMs are never going to be erased and re-written again once programmed, you might want to use the less-expensive one-time-use equivalent of the These single-use eproms are encased in plastic instead of ceramic, and don't have the erase windows.

I guess different to my issue. Day one my panel looked like this: View attachment I freaked! After one compensation cycle it now looks like this: View attachment R1DDS Well-known Member. JohnnyFireOne Novice Member. The panel has not been bonded properly. Had it on my E7. Swap needed I am afraid. Hi All, Very much enjoyed reading the entire thread and thanks to all the people that post answers and info. Joining the club!
Really hoping to be wowed, judging by the comments on here. ArthurSlough Active Member. ArthurSlough said:. Last edited: Oct 28, Just had the OLED panel fail. Had the TV on for about an hour this afternoon, was just logging into Netflix when the TV switched off. After four or five attempts I managed to get it to switch on again only to have a blank screen with the occasional slightly visible vertical line moving across.
Now got to uninstall it off the wall etc and re-box to return to John Lewis to get it swapped out. Just had the same thing happen to me. Updated to the latest firmware, watched youtube via app and nvdia shield via hdmi for hours and when I switched to Netflix via app the screen went blank. Now I have greyish forms moving when I change the channel or the source. Unfortunately the update via the LG TV Plus Remote app only checks online where there is still the I'm pretty pissed right now as I was looking forward to the next few days for gaming and tv and now I'm stuck with nothing.
Kotatsu Neko Well-known Member. My TV grabbed the latest firmware a few days ago and now my AVR is complaining that it's not compatible with the version of Dolby Vision in the TV. This has nuked DV for my Apple TV 4K, as it's routed through the receiver. Nice job LG, thanks for that. And for your next trick? Bittern said:. Quick question regarding ATMOS via ARC? Why is it my Denon XW can recieve a ATMOS signal when watching some content on Netflix The Wheel Man for example and the clips from the Dolby App, BUT ATMOS will NOT work via a external hard drive going into the USB at the back of the TV.
It just comes out as DTS? Any ideas why? Bittern Well-known Member. Here's a pic i did earlier. Chrissywis said:. Thanks for that. Bit of a pain to have to switch as I like the Dolby atmos on the internal speaker but hopefully they'll fix it in due course. PulsedHalo said:. Hey all. I soooooo need help here. I got my B7A TV last week with an SJ8 sound bar. The sound sync issues are driving me CRAZY and it has nothing to do with the SJ8. If I use the internal speaker on the TV I still get sync issues with the sound.
The Video is slightly ahead of the audio. I think I did all of the necessary troubleshooting steps mentioned on other forums. I've used bypass. I turned off Dolby Atmos. I'm running the latest firmware. For the life of me I cannot get the audio to sync with the video. Right now I'm currently using the SJ8 with optical cable. I'm using an Apple TV 4k as my main source but the issue also happens with my Chromecast Ultra.

Last edited: Oct 29, JoeSepi Well-known Member. I will say it again Which is NOT a TrueHD signal. Hence why that works via ARC! I give up i just keep repeating myself AndySmith Active Member. Got ya I thought it could send it back down hdmi Arc. So pretty pointless then really as who uses the internal speakers anyway. And even if you did you are not going to get any Atmos effect. Although as the above post suggests you will still get some kind of Atmos down the hdmi Arc just not full high bandwidth.
But anyone with an Atmos supported Avr will most probably wire thier UHD Blu-ray player etc straight through the Avr anyway. Kadajo Standard Member. You must log in or register to reply here. Similar threads E. LG OLED B7 Help. Elward27 Jan 31, LG TVs Forum. Replies 3 Views Jan 31, Elward
