Spectrum Computing

I had an RGB Lead from Retrocomputershack connected for the picture and first some headphones and then the powered mini PC speakers in the 3.5 Stereo Jack of the Internal mod. I have it connected to pins 1,4,5,6 ( A,B,C & Gnd ) and the flylead connected to pins 34,35 of the ULA as per the destru...

Well I disconnected the Tape and there is no Improvement so the problem is on the main PCB some circuit is generating some serious interference on the Audio.
It's almost like you can hear high pitched whine as the Spectrum processes something and then goes back to noise once it is finished.

Hi I have bought a +2 and I went with the Grey +2 rather than the +2a because I heard about the corrupted audio on +2a's and +3's. I seem to have backed the wrong horse here. The Audio is overridden by a humming noise that drowns everything out it was worse using the old power brick but it improved ...

Hi everyone. I have just obtained a +2 Spectrum ( Grey ) and it was made in Taiwan not the UK. The only info I can find to add an external EAR input onto the cassette is based around the UK Cassette PCB. Can someone give me some insight into fitting one for the Taiwanese model cassette unit please a...

Hi Just thought I would follow up on this It turned out to be a SMD component that was not soldered on one pad. One of the two 470R resistors coming from the Crystal. By the time I found that I had already shelled out £9 for a new AY Chip. So it works fine now. Yeah I did they gave me the cost of th...

Yes i get the same value back, does this mean the AY chip is working properly??? Well, the chip is correctly connected at least. That says nothing about the output. Try this for the output, it should give you 3 channels of 440 hz tone, at maximum volume: ; Output channels A, B and C with tone, no n...

Most AY boards need their audio output connecting to an audio amplifier. The output from the sound chip can't drive headphones. Mark I tried it with headphones and i also use the left/right audio inputs on my TV using a 3.5 to RCA Phono x 2 and i get no sound when selecting 128K sound on Into the E...

Exolon won't play the music, if it finds an original 48K ROM. Try something like Into The Eagles Nest, which lets you manually choose 48K/128K sounds. Try this and see if you get the same value back: OUT 65533,0 OUT 49149,x PRINT IN 65533 Yes i get the same value back, does this mean the AY chip is...

I have not tried that i have to admit. I have tried Bosconian 87 and that is supposed to have AY music, with headphone all I can hear is some distorted clicks,scratches,white noise where it almost sounds like it is trying to play some music. I think the AY chip may be faulty. Are there any ways to P...

Hi I have just bought a simple AY board with a Pass-Through connector fitted and i cannot get any sound out of it. There is some faint distorted sound playing Exolon but only shooting and explosions - no music, no sound at all from Cybernoid 2. These are both listed as being 48K/AY games. The pass t...

divMMC Probably the most common hardware to load and save from real Speccy or clones. https://www.sellmyretro.com/offer/details/divmmc-future-sd-card-reader-for-the-sinclair-zx-spectrum-32185 https://www.sellmyretro.com/offer/details/divmmc-enjoy%21-sd-card-and-joystick-interface-for-any-zx-spectru...

Probably the least used hardware. Drop in replacement of real Microdrive.

I did have one reserved but had to let it go due to financial pressures I do like this solution a lot though.

Hi I am a bit out of the loop these days and was wondering what hardware and methods do most people use for saving progress for any programs they are working on. I am talking about a 48K Rubber Key or 48K+ only i don't have a +2/+3 and talking about real hardware not Emulators or do most people use ...

OOOpps :oops: I was using a Modern stereo 3.5 Male to stereo 3.5 Male plug. My other Spectrum is a +2B and i didn't realise i needed mono cables to get the sound. I have managed to get some joy with a Mono-Mono lead converting TZX's to Wav's and then changing them to 24 Bit PCM and upping it to 4800...

Hi I have just acquired a really nice condition little 48K Rubber Key Speccy along with a working ZX Interface 1. I didn't give it a full once over until this morning as all i had time for was to turn it on and give the keyboard a test. So today i tried to load some Wav's, TZX's and finally some rea...

Hi
Could a Mod close this as i have a copy now, Thanks.

Very sad news - never got to meet the guy in person but everyone who did spoke very highly of him. His artwork speaks for itself...

Would a work around be to load in by tape and save a snapshot on the DivMMC? Or alternatively snapshot it once loaded in an emulator and transfer to the SD Card. IT isn't a multi-load game is it? I tried a Z80 Sanpshot and it just starts right away and no keyboard input works the manta's keep flyin...

Perhaps try doing...

Code: Select all

OUT 32765,48

...before loading the game.

Tried that and i didn't work - maybe the .TAP is no good - I'll try another
