Re: Exidy Sorcerer II with S-100 Expansion Unit

Oh yes, Paul, I have one of those (with a faulty disk drive). It's a Liveport FDM 180 and it contains a boot ROM, so is connected to the bus at the back of the Sorcerer. The problem is that I cannot see all of the boot code, probably because some chip is bad on the drive or the connections are dodgy...

I went through the same process as you and bought the Rigol 1054Z, again from Batronix. I'm a newbie to 'scopes but as far as I am concerned it is the biz. Especially after applying the "hack" and considering its relatively low price, I think you cannot go wrong. The feature list (post hac...

Re: Bank Holiday

I spent BH Friday under a 45 year old Lotus.
On Saturday I went out to score some Easter Eggs.
Sunday it was a Lamb roast with the mother in law.
Monday I curried the remainder of the lamb.
The rest of the time I sat in front of the fire and gazed out at the miserable weather. :(

Re: Worth Taking a Look At

Ask yourself why you collect computers. To play or preserve? Then you'll know the answer to the "build it or not" question. If it was me I'd buy a built ZX81 to play with and keep the kit as is.

Re: Worth Taking a Look At

@LB - It takes less than an hour to build a ZX81 from a kit, then the value is gone. Maybe you should frame the case and components and hang them on a wall?

Re: ZX Spectrum next... Anybody backing ?

But writing a new game which only runs on new hardware... that's just... writing a video game. Isn't it? Yes, but it is written in Z80 assembler I assume, and that is an interesting endeavour to many. It's nice that they are able to share the fruits of their work, and nice that others have the abil...

Re: A special day for a very special computer!

I had an 8 bit parallel I/O board plugged into the back of my self built ZX81 that I tried to generate polyphonic tones on, using one data line and a speaker. The code was hand assembled and had a nested loop to trigger a 1->0->1 state change back and forth on the line the speaker was wired to. This...

Re: ZX Spectrum next... Anybody backing ?

Warhawk looks like Xenon on the ST:

..sort of. I mean the game play is pretty well the same. It is impressive but looks very un-Spectrum like, apart from the right hand panel.

Is that a bad thing? I think not.

I have bought quite a few tools from them over the years. In particular a UNI-T multimeter for around £60. I figured it was about time I had a decent one. Then I saw a review on EEVBlog and wasn't very happy at all. On the other hand, it has served me reasonably well, and I don't use it for high vol...

Re: Don't have a desolder station or hot air gun!

I found a hot air gun (paint stripper) could remove a bank of DRAM from a PET motherboard, but it nearly ruined the board, even with the narrow nozzle. That's when I bought a Duratool desoldering station.
