As far as 8bit computers go the electron was a poor perfomer really the graphics where easy and the programming was easy which made up its market ...keen bbc enthusiasts......its creased in its ula to exe code or retreive memory thats why its 2mhz, its not the most efficient method....i use to have 1 when i was at school, i would bit map mums knitting patterns into its vdu and color was somthing its behind the curve with being a 1983/4 computer, it should of been at least 32 to 64 colors ,commodores ted was producing 121 colors in 84, atari had 256 nintendo 64 on screen colors the electron technology was still in the 70s it was a cut down version of the bbc b which evolved in the late 70 early 80s the electron was just a system to cater for people who wanted to learn bbc basic.....and they was late with it .they had warehouses of machines that were disregaurded for sinclairs that was a high selling product

could one of these be used as a shift register or somethin, or what can ya do with GALS?

This programmer gives me nothing but problems. It keeps telling me "check device ID" when i flash the chip, NOT when i read it. If i uncheck the check ID, it will flash but it will not flash properly. If i remove the chip from the board, it will flash ok no problem. I dont get it.

One of the worst repair videos ever. Changing all the chips to find a fault is meaningless, and not the way to operate: you have to study first, and if you don't know the job leave it to others who know how to do it, instead of publishing similar things (watch some repair videos of "Noel's Retro Lab" to see what it means "Repair")

Thank you. This is such a thorough and helpful video. I dug my BBC out of the loft and turned it on and although it ran okay it was obvious from the smell that something was amiss with the PSU. I followed your video carefully and now all is well.

I love it. I will use it to test my bad PLA. Thank you.

That machine might be liked or not :-) I‘d probably leave it broken. I have recently trashed a Santa Clause, which looked completely tasteless. He was shaking his ass and playing horrible music.

I was a little apprehensive about configuring my PC2014 Pro and powered up for the first time. Your videos have been so helpful (and interesting). I've so enjoyed putting this computer together so to finally see it come to life was wonderful. Thank you for talking the time to make thus brilliant series!

There's a patched version of Elite that runs on the ARM with filled in polygons. Very impressive. Check it out!

Посмотрел и это видео и обрел опыт. Использовал и тут яндекс перевод при просмотре, хорошая работа.

I have a tl866 ii plus , and there is no chips 74 in the menu at all, I added one of the chips myself. But it is strange that 74 is not there at all(

My friends and I often made cassette audio mixtapes of all our favourite 8-bit chiptunes back in the 1980s, and Tim's music was a particular favourite of mine on the Amstrad CPC. Nice to see his work being preserved and better understood.

Do you have permission to share Tims source onto Github? Would be nice if they could be shared.

God, please do 🙏

Do you have any details of the FTDI adapter you are using. I didn't get anything in my RC2015 Pro kit, so need to source one.

You skip Part 4 of this series. Is that intentional? or a mistake. The last video in the series is part 5, Also, how far did you get w/ building an MSX compatible computer? (breadboard or pcb?)

I have a blown Atari ST supply. I added up the price of replacing components and it cost more than just popping in a complete Chinese power supply. Not original doing it that way but if you are not well to do then needs must. Luckily I have a lot of Atari St units so i just swapped one over and added the ST to the spare parts collection. I only have one BBC model B and its blown so I will have a think on that. I may have to just label it and put it away.

I really wanted you to show a parts list.

I am just about to try and fix mine for sentimental reasons. How did you get voltage to the motor did you connect batteries? What did you do

Ula+ spectra zx hdmi vdac2 zx evo?

Where do you download the games from .I don't get it

Hi mate, you said in the intro that you used this to test PALs? I've had mine a while now and not really played around with it until now, but I can't find any PALs in the search list? I've got some old PALs and GALs that I wanted to check, but can't find them listed. I'm running the very latest version 12.63, on the TL866ii PLUS. Many thanks.

Watching someone else solder can be quite relaxing; brought a smile to my face whilst doing the washing-up. Thank you.

I asked ChatGPT to convert some python 2.7 to python 3.8, it failed miserably, although people have demonstrated ChatGPT writing programs I don't think this is one of its strong points.

can but every answer need check. AI not know is it correct or wrong

I just ordered one of these, looking forward to building it, thanks for your videos, most helpful.

I know these computers are from another country so will it work on my American tv?

I find making the resistors such a tight fit puzzling as there are so much unused space on the PCB.

Any updates on this? Is there anything there we've not heard, or different versions/demos of the ones we have? Thanks.

Mine works better in the EAR socket on the ZX Spectrum. I can use jumper 2-3 then,

Very interesting, I'm doing some research into Einstein cross-development, with a view to possibly basing a computer museum exhibit on it. I came across your introductory on the Einstein forum and followed the trail here. I'd be interested in any insights you have regarding the hardware and software you used for cross-development back in the day, and whether you think it might make an interesting use of a museum Einstein.

Did you cut the trace per the instructions? Thanks. " However, between slot 3 & 4 and slot 10 & 11 on the standard bus, there is a double row of holes where the copper joining them is exposed on the underside. "

I loved eliza. I was a schoolboy then. Had emotional connect with it....those golden teenage days

I just build the breadboard NOP test circuit, works great, found out A3 and A15 are dead on my 6510 😞

nice always liked the ELK never had one of course but they look like a computer should...was a spectrum lad, amstrad CPC 464 then atari ST, amiga.

Sometimes a via is needed from one layer to the next … they look like holes …

hi , i recently bought one of these and all the domes are split in half i have removed all of them im having trouble finding them can you point me in the ebay link thanks x

A very cool game, I like it most !!!

Hi Can u help me for programing

I'm told it is possible to use 4164s to replace 4116s. Bend out pin 1 and 9 so they don't connect to the PCB, then connect pin 9 to pin 8 to get 5v into Vcc. Pin 8 is A7 so it is set high leaving 16k addressable like a 4116. Would this work for a ZX Spectrum lower RAM?

Impressive! We will code with support of chat bots on regular basis.

Looks like the replacement round dome switch wouldn't be suitable because it needs to bridge the trace that completes the circuit when clicked. This is the reason why the original domes are 3 legged.

Tim is my favourite game music composer so I'm looking forward to hearing some of this music!

Looking forward to see how this pans out, interesting stuff! Thanks.

Oh, fancy! I was going to ask which chips they were for, but took a look at the description. That's gold right there!

What a treasure!

Thanks. I got a cable for my Einstein a couple months ago and couldn't figure it out - gonna give it another shot now.

So much fun

Had an Arduino Uno, a dev shield (had some buttons already on it), and an LED display I got in an Arduino kit. Added an Arduino SD card module and a mono plug and built a TZXDuino for my TS1000 (USA ZX81 from Timex). Works great. But yeah, some of the 16k games take a while to load. :-)

Perhaps the truncated code (missing part of the print_char routine) was down to resources - rather than 'intelligence'?
