Sadly my health is still not good. Time to sell all my Einstein stuff including Speculators (ESP) and Silicon Discs (ESD). Please see full list below…
Hi Tony, don’t know if you’ve sorted this out yet but I’ve sent you a direct message about it.

Cheers
Please wait, I'm not well.

Re: Speculator

Offers considered. I'd like at least £500, excluding DMX80.

Re: Speculator

Sadly my health is still not good. Time to sell all my Einstein stuff including Speculators (ESP) and Silicon Discs (ESD). Please see full list below. Assume that I can't support any of this in the future. For ESP & ESD, copy PALs and program GALs from the one PCB of each that works. Also for ESD co...

Re: Speculator

Apologies for not posting here for months. Unfortunately my Meniere's symptoms returned in the spring and I have decided to sell all my Einstein hardware and software, which will allow other people to enjoy the Speculator and Silicon Disc. Something that is completely free is the source code for the...

Re: Speculator

I was sidetracked a bit but now keyboard problems are delaying me. Some number keys get stuck / spring back very slowly, the P key doesn't work at all (not helpful when trying to run SP1.COM) and all the other keys that do work play a tune when I press them. Any ideas? Aside: is there a list of whic...

Re: Speculator

I understand there are three Einstein floppy discs of Spectrum Programs that are already available to work with the Speculator. Would they work from a Gotek image (in Drive 1 on my system)? I suppose what I'm asking is if the Speculator is happy to co-exist with whatever DOS is initialised. The exi...

Re: Speculator

I sold all my Spectrum tapes bar one years ago, which means I can load only one game with the Speculator - and it works! spectip1.jpg spectip3.jpg spectip4.jpg A few of the Einstein's keys are sticky and CTRL doesn't work. Colours are washed out in the photos but monitor picture is amazingly vivid w...

Re: Speculator

Should be possible on a PC to copy spectrum prog files into .dsk image files and then load them on the Einstein using a Gotek. What is the Gotek emulated diskette size? My Einstein computer and colour monitor work, not tried the Speculator yet. Software for that could go in ROM and therefore would ...

Re: Speculator

All my Einstein stuff was down from the attic before the cold spell in December. Most of the software effort will be directed to downloading Spectrum .SNA snapshot files via RS232 and it might be possible to go faster than 9600bps. Does the Einstein have a 8251 or 8251A? Any thoughts on other ways t...

Re: Speculator

I haven't forgotten about the Speculator or the Silicon Disc. I've been badly delayed by another project but all my Einstein kit is down from the attic and ready to try over the weekend. Fingers crossed!
