Nice work there Jan. That was the Spectrum version I always wanted as a kid but I ended up with the earlier 48k with the rubber keys. I remember picking up the "Fuller" which was a keyboard replacement swap out you could do to the earlier Spectrum...got it from a car boot sale and having to repair it myself. I borrowed my mothers nail varnish to paint the leads coming off the membrane wires so they wouldn't short.. but I accidentally soldered them on the wrong way around & had to desolder the varnished leads turn & turn them around & re apply it.. nearly intoxicated myself... I couldn't get off the ceiling haha but I got it working in the end.. those were the days.. great work there.. love your videos..

No need to put a heatsink on the CPU - quite a must for the ULA tho as Sinclair decided to ignore the specs by Ferranti which is why they're always on the edge of boiling themselves (modern CPLD replacements are available - NebULA and vLA82 work nicely here). Additional mods I'd recommend: Replacing the 7805 with a DC-DC switchmode regulator (saves you the heatsink) and putting in an EEPROM/EPROM instead of the original Sinclair maskrom (lower power consumption). Also those original 16k*1 DRAMs can be replaced with 64k/256k types - saves you one additional power rail (-5V) and lowers the load on the 12V (which will only be used for the Y/C -> Composite circuit). Optional recommended mod: S-Video ... drastically improves the video quality over the quite crappy composite on 48k Spectrums.

@SwissArmyTin: As an American, why not get TS2068 on eBay, dirt cheap. TS2068 is the American cousin of the ZX Spectrum, with a cartridge slot, and a dedicated General Instruments sound chip, AY-3-8912, whose ports are also used for providing two joystick ports.You can replace the system ROM with Sinclair ROM, you got yourself a Spectrum. A better solution was having the Spectrum ROM on the cartridge. By inserting the cartridge and booting, you got yourself a Spectrum. The bus behind the computer is not compatible with the Spectrum bus. BUT there was a small hardware adapter ( named The Twister) which made the two buses 100% compatible. For example one could run Spectrum Micro-drives, as well as Floppy Drives, and Sound Cards, etc. Oh the Portuguese version was TC2068, and Brazilian was TK 90. Both the Brazilian and Portuguese versions had RGB outputs. The TC2068 floppy drive system was also equipped to run CPM.

Honestly I think it's worth replacing the 7805 voltage regulator with a modern switching mode regulator like the traco power and removing that huge heatsink altogether. some people say that's losing the original feel but so is adding heatsinks to the ULA. The spectrum's lifespan would be greatly increased by getting rid of all that heat that gets trapped with the aging components.

Grower1973: there were multiple assemblers and disassemblers, including language packages like Pascal, C, Forth, etc.The American version of the machine called TS2068, had a cartridge slot. A person in Indiana had developed an Assembler/Disassembler cartridge to which you could boot. The beauty of the disassembler was it wadded through the system ROM with the floating point routines with ease, interpreting all the PUSH/POPS of stack arithmetic, with explanations. For Assemblers/Disassemblers go to Internet Archives. Find the Spectrum Applications section. Some of the best packages are available there for download.

I used the time-honoured tradition of writing the assembler out on sheets of squared paper, writing the corresponding hex values in a column to the right, then typing them in and seeing if it worked!

@@JanBeta There were assembly compilers - such that even could output DATA for basic, so effectively it ends as a basic program data has a for loop/'poke' and 'call'. Personally I could program in HEX as I had no working cassette player, or cartridge - virtually anything that could work be non-volatile memory - so I had to learn all opcodes by heart. The major downside was the the computer I had RST signal actually cold restarted the machine, wiping all the memory and NMI was unable to restore from an invalid optcode... so one mistake and it started from scratch (entering the data, finding the issue and so on).

From what I've heard Thermal Grizzly Kryonaut is one of the best thermal compounds you can get. I'll be using it when I build my Ryzen 4000 gaming/workstation PC later this year. They also have a liquid metal compound used for delidding modern CPUs, but I'm not doing that and now that both AMD and Intel solder the heat spreader, it doesn't help as much as it used to. For this it's overkill. lol

I once destroyed a laptop keyboard by getting WD-40 on it, it made the rubber mat swell up and wrinkle, making the keyboard useless.
