Read the previous post...  :smt006

Yes, your cable is beautiful!

Unfortunately, I don't have a SCART TV, I have a professional CRT monitor, a Panasonic BT-H1390YN (without SCART socket) ... that makes things a little awkward.

<edit>

I guess that I could always get your cable, cut off the SCART socket, and then solder on my own RCA jacks (or BNC jacks).

Hi All!

I don't know what happened here? :-) I thought, I started this year with a respectable stock of SD adapters ...
All adapters have been taken away in the last month, currently out of stock. :-/

I just started scratching how i could manufacture ... because some items rely on chinese delivery.

I'll be back when I succeed, I hope later this year!

You don't have to cut it. I can also make you a cable with only the EP side connector on it + 5 ft cable. :)

I'm going to guess that it was from the people that recently bought those 30+ eBay Enterprise 64 computers that were found in Egypt.

I suspect that you've got a pretty-accurate list of the new owners! ;)

I'm curious, would you mind saying how many of your purchasers came from North America vs European countries (since one of the main Egyptian sellers is listing on the US version of eBay, with prices in US dollars)?

Thanks! I'll PM you with some questions. :)

I have a quick question about the Enterprise 64/128 SD Adapter Rev3.1.

Looking at the circuit board, I can see that it includes its own 16.00 (MHz?) crystal for timing.

Does that mean that the SD Adapter does not use the Enterprise's System Clock signal?

I would like to change the crysyal on my Enterprise motherboard to use a 12MHz crystal (to create a 6MHz Enterprise), and I want to know if the SD Adapter will still work.

Yes, because no clock output at the cartridge connector.
SD will work up to 10MHz.

Hi SzörG,

I'm looking to buy one of your SD card interfaces to send to Neil at the rmcretro youtube channel. I sent you an email, but haven't yet received a response. Are you planning to make any more of these soon, and how much will they cost including shipping to the UK?


Many thanks,
Pete

Re: SD card interface - still a LOT of interest

Yep, still a lot of keen people on Szergej's SD interface ... quite a few here now in Australia.  You could probably sell out a batch just here.

I've pinged Szergej a few times via email ... don't want to pester ... figure once per year isn't pestering ;)

I know it's his hard work, but how about releasing the Gerber files, etc.?  Or even selling them - I'm happy to pay for them to compensate for his work.

The SD interface that someone designed for the COMX-35 is now apparently lost as the poor fellow that designed it passed away before they got around to releasing them.

Brett.

The same problem occured in case of Videoton TVC (Hungarian cousin of Ep128): No original SD-card reader was available.
Sándor Vass designed a new one, which is completely public, you can find the necessary information on GitHub:
https://github.com/dikdom/TVC-NanoSD
Perhaps it could be easily adapted to Ep128, since the disk access / DOS of the machines is quite similar...

I'm quite sceptical about that. The project page states that it is some sort of a tape emulator and loads and saves .CAS files. Those are not exactly what an Enterprise computer expects. :(

Hello Brett. Was the Enterprise sold in Australia in classic times(80's)?


----

On the other side, as for the Enterprise version of the SD, I think there is enough information if Kyp has achieved to implement it on the FPGA and IstvanV on the emulator(Zozo's software does half of the work).

But let's wait a little for Szorg. He has always come back.

The Enterprise was never officially released in Australia but as we got the same magazines like Your Computing etc it was well covered and lusted over.

I am also another one from Australia (and know of at least one more besides Brett) that are seeking Szergej's SD interface as well
