Spectrum Computing

Nice game, I'm enjoying playing it and glad there 9 lives.

I have bought most of the Fusion magazines and some of Chris's books. All are very well done and a great read. I take a long time to go through the spectrum books - Read a page, play the game, Read a page, play the game, repeat...

I got a very quick reply from TFW8b.com and they suggested reflashing the DivMMC. Something I didn't think of or realize could be done when the system wasn't working. :D It all works now!! :D To Reflash: 1, Pop out the SD Card, but keep DivMMC attached. 2, Load the Flashing Tool which is a .WAV on t...

I tried another SD Card and also used the formatting tool recommended on the TFW8b.com website. Additionally I tried the older version of ESXDos 8.7 and 8.6, same result with on all fronts.

I'll email TFW8b.com again, perhaps there is an issue with the DivMMC.

Thanks for all the advise.

I cleaned the edge connector with a Q-Tip and Isopropanol Alcohol. Yes the DivMMC connector has the locating peg installed. Without the DivMMC connected the spectrum works fine and has had a good hour of play time.( Where Time Stood Still, Rodland, Nosferatu ) I can load games from tape and the mic ...

The new z80 works fine but I get a similar result when the DivMMC is plugged in. :( The image is slightly different and occasionally the reset button changes the border colour to white, black, blue. https://i.postimg.cc/YG886VFY/IMG-2.jpg Here are the mods from the previous owner. - Buck converter -...

I bought this Z80 for $5 which should arrive next week. If it works I'll let you know, if not I'll probably have more questions.

Really enjoyed watching how you debugged the issue and the tools used.

Did the Z80 CPU you bought work? Did it solve the problem with your DivMMC?

I think that the thread below is very similar to my issue, which makes me think the Z80 has a faulty M1 pin. But I don't really know how to test it. https://spectrumcomputing.co.uk/forums/viewtopic.php?f=22&t=1152&p=16635&hilit=m1+z80#p16635 Also, can I safely install any 40pin Z80 cpu b...

Hi, My Spectrum +2 (grey case) was working great with a DivMMC. Then recently it would take a couple powercycles for DivMMC to boot into ESXDos. Today I get nothing but a garbled pink screen when using it with the DivMMC. When in this state the reset buttons on the +2 and DivMMC also don't work. Whe...

I just purchased a grey +2 from ebay and have been playing with it here in the UK while I am visiting family. It has a few upgrades according to the seller - composite mod - recapped - sound mod to play from external tape player - Voltage regulator is now a buck converter - Transistors TR4,5,7 fixed...

Thanks for the detailed reply, it helped a lot.

I would like to use a Spectrum here in the USA but wasn't sure of the technical issues? Also I clearly have no idea about TV signals.. :D 1, I'm guessing a suitably sized regulated DC power supply would be needed. But would the different mains power frequency over here (50 vs 60hz) be an issue for t...

lol, nice but I'll pass on that one.

Hi, I'm Richard and my first computer was a 48K+. I love reading about and playing spectrum games, these days I only play on an emulator. Sometime I would like to buy a real spectrum, but living in the USA makes using a real one a little more tricky. Big shout out to Fusion Retro Books/Magazines and...
