Re: Eye-watering ebay prices

That's interesting Jon. So he is selling up because he's exiting, in this case, the Memotech "scene"? Not exactly, no. He is happy to sell items if there is someone who is willing to pay the price he wants. I’m not sure he’s exiting, as that would mean he was ‘in’ the ‘scene’. He does this with a w...

Re: Edge connector woes

That does not look too bad. A bit of desoldering and some new solder and it will be like new.

Re: Edge connector woes

The technique to refresh edge connectors on other machines is to put on lots of flux and then a reasonable amount of solder on each finger and make sure that the new solder covers the whole thing, then use desoldering braid to suck off the excess solder, pulling the braid with soldering iron on top...

Re: Take care when remove ics (Saved a VDP)

Unfortunately the metal used for the pins on some chips corrodes and weakens over time. Obviously this only becomes a problem if the unit is stored in less favourable conditions.

Re: Eye-watering ebay prices

This eBay seller is well known for their way of trading. They always list items at well above the market rate, and keep re-listing month after month.

Re: Best dust cover

I don’t know about now, but some years ago there was a guy that would make custom sized dust covers. Some on the World of Spectrum forums asked for dust covers for the ZX Spectrum +3. I jumped on the same bandwagon ;) If you search the U.K. eBay site for “dust cover zx spectrum” you will find simila...

Re: Question #2: EXEROM and tape loading

I think your comments are a bit harsh. The ZX80 and ZX81 did not have any ability to load code or data files. You could only load them from BASIC as part of a normal program LOAD. We now know of three different official ROM versions, the first one having a bad mathematical bug. The second version al...

Re - IDE cables: You want the older type that uses standard 40 way IDC connectors with 40 way ribbon cable, often described as PATA IDE or ATA/ATAPI not the later 80 way ribbon cable type with specialist IDC connectors for the faster HDDs. IDC means insulation displacement connector. You also don’t ...

Re: Question #2: EXEROM and tape loading

The other problem, is that fitting a modern EPROM / EEPROM or flash ROM to a MTX board, requires wiring changes to the board. Which is further complicated by there being two different main boards in widespread use. One of which uses three ROM chips, and one of which uses only two ROM chips, So not s...

I am also sure that someone else will jump in here - Martin perhaps?

Dave
Martin also talked about how games loaded code blocks here ;-)
