Ok. Thanks for the info. It's time for shopping ;)

Is it a proven supplier ? Someone has already shopped there ?
Payment by card only directly from the site. Too risky without checking.

Exxos (Chris) is a well known person in the ATARI scene. Many years ago, I financed the last run of the PeST mouse controller by him and never had a problem. He had bad experiences with Paypal and therfore refuses to use it.

Sorry, it is the first this time I see the website.

They have a huge amount of WD chips, also VL. They warn that these chips get hot... It seems they know what they say.

1 pound is almost 1 Euro now and they still are Communitarian...

Unfortunately, I was too optimistic about EXP2. I can close the top, but it bends the plastic out about 1mm.

That's good to know, I'm sorry that you found out the hard way! ;)


Btw., I was not able to use a standard double-row header on EXP1. It seems the distance between the two rows is off. I used two single rows instead.

I saw that you've used the male header on the motherboard's EXP1, rather than the female header (which is how SainT's board seems to usually be installed) ... I wonder if that has anything to do with the distance problem.

The solder tails on a female header are usually a bit thinner and more flexible than the solder tails on a male header.

Congratulations! It is excellent to see another successful breadboard circuit, just like Dangerman's pictures a few pages ago. :)

I see that you have added a header to EXP2 instead of wiring the cable directly into the motherboard ... how is that working out for you?

I was under the impression that there isn't enough physical height inside the case at that point for a header and DuPont connectors, which is why SainT and the others wired the cable directly into the motherboard.

Have I misunderstood the earlier posts?

It would certainly be easier to use 2 5-pin DuPont cables instead of soldering the wires directly into the motherboard.

Thanks. Unfortunately, I was too optimistic about EXP2. I can close the top, but it bends the plastic out about 1mm. I will remove the header or at least the front row and solder the cables directly.

As I am new to EP (yes I got my EP64 from Egypt), I followed this great thread and built my own memory extension (prototype). I am using a GAL16V8 for address decoding and a AS6C4008 SRAM chip.
I just finished my prototype and at least the boot screen seems to work. It is a bit scary to unplug and reconnect the  keyboard membrane since it seems to be very thin, so no real tests yet.

Az oldalon a játékokat nézegetve azt látom, néhány mellett ott van, hogy (ISDOS). Érdemes lenne külön oldalra tenni ezeket, amik nem futnak az alapkiépítésű gépen, mert külön oprendszer kell hozzájuk.
Lehetne pl. egy külön IS-DOS programcsokor, de oda mehetne minden más is, ami IS-DOS alatt fut, nem csak a játékok.

Hi,

En mondjuk komplett mini Enterprise-t gondoltam kulcstartonak, olyan 5-6cm-eset, szineset...

De most meg az alkatreszek vannak eloterben, hogy haladjak is valamivel, atterveztem a joyharangot, ez lessz a G2JoyBellSR40Gray es G2JoyBellSR40Green.
0.6mm-el novelt falvastagsag, es ahogy a nevben van szurke es zold szinben lesz kaphato, mar ha hajlando vegre a gyarto elkuldeni az anyagot hozza...
