It seems very quiet
Wow - no new posts for the past 3 days - this must have been the quietest period in the ZX81's history over the last couple of years....

Re: It seems very quiet
hmmm...yeah, obviously nothing interesting involving zx80's or '81's at the moment!...... what would be great is someone coming up with new production 'clone' boards for the Microdigital TK85.... a discrete logic ZX81 on a spectrum size/shape PCB, with onboard dynamic RAM (4116's - ugh , but board has links for 4164's ), and onboard zon-x sound circuit... also has extra 2k ROM for 'fast tape load' routines - could maybe be used for other purposes??

Re: It seems very quiet
Why use DRAM? The 1k byte ZX81 uses SRAM. [Okay, some 2k Timex boards use psudo static RAM (DRAM that looks and acts like a power hungry SRAM)].
If I were building one, I would either use two 32k byte SRAM chips or one 128k byte SRAM chip.
Anyway, sshh. It's winter and the zeddies are hibernating
(And I'm busy with work and real life plus winding up people on QL forum and StarDot forum )
Have still not found time to build my ZX80 Core yet (but I do now have nearly all the parts).

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer being good this year.

No, work is going on (especially during winter time) to have something new at the next ZX-Team meeting in April in Mahlerts/Germany:1024MAK wrote:Anyway, sshh. It's winter and the zeddies are hibernating

Re: It seems very quiet
To '1024MAK'... well, yes, if making a modernised version of the TK85 , much better to use SRAM, but in my case I have a load of 4164 equivalent chips lurking in a box waiting to be used on something interesting ( I think I also have a bag full of 41256's...somewhere...and some 1Mb 30 pin SIMMs..?!) But a 'straight copy' of the TK85 board would be good enough!

Re: It seems very quiet
To 'zx81jens'.... C64??!! Shock, horror!! .... (alright, I admit I have 2 C64's, 1 C64C, 2 C16's, 2 plus4's )!, but about 6 ZX81's, 1 ZX80, and at least 10 spectrums of various versions!, Sinclair stuff is definitely my 'thing'

Quiet? Some of us have been very busy coding...

Re: It seems very quiet
As for me, I entered the "quiet work mode", hehe.RWAP wrote:Wow - no new posts for the past 3 days - this must have been the quietest period in the ZX81's history over the last couple of years....
I'm collecting some news to the newest mag's issue; maybe will take some some free time from work, to write it all down.
Another thing is, I have computers of several platforms. Mostly I use
- ZX Spectrum
- ZX81
- Amiga
- Atari ST
- Atari Falcon030
- lately some Commodore 264
That's why "it comes to me by waves".
Also - it's required by a limited place in my room. At the moment I have connected two Amigas and Speccy2010 (because it's as small as ZX81). Until I'm done working with them, they have to be "on the table" permanently and other machines wait for their turn.
Last times it was turn of Amiga 500 and I'm preparing something on it - http://soundcloud.com/yerzmyey/yerzmyey-give-it
But I cough myself thinking more and more often about ZX81 SoundTracker, last weeks. So... Who knows.
