Re: Please Check legacy ICs before use .
If anyone else finds some incorrectly marked ICs or DUFF ICs .. please leave details on the Forum for others to read and be aware of.. I've come across CPLDs that have been pre-programmed.. This reduces the number of I/O lines by all accounts.. ?? Though I don't have full details about this. Found a...

Please Check legacy ICs before use .
Hi. Some of you may of received legacy ICs from me, Z80s, V9958 etc etc . These are untested.. so best test them and verify them .. don't just take it that they will work .. Dave has tested some Z80s and found most where Z80Hs 8MHz type or so we think .. a few where DUFF and only a small number true...

Legacy IC from Lez
Hi.
Just a little CAVEAT
As some of you may be aware the Z84C0020PECs sent by me turned out to be mainly NMOS Z80Hs ?? So best check ICs before using .. any DUFF or lablled incorrectly will be swapped for good ones..
Hope this helps clear things up.

Re: 6309E Serial Port Computer
Good to see the ICs being used.....
Would look great with a V9958 board attached... sort of a Super Ultim809..

Re: Memotech MTX Series 3 for next years Memofest ?????
My Very Generic spec would be based on minimum chip count and costing : the HD64180 : probably 8 or 10 MHz .. 6800 or Z80 BUS 'R or Z' ?? These are Cheap, which I like ! It has the following features: Memory Management Unit (MMU) which supports 512k bytes of memory, and 64k bytes I/O space 12 new in...

Re: V9958 on an MTX
I've looked into the V9900 Graphics chip... quite easy to source but surface mount !! Used in the Kiwi Homebrew computer cost about $20 each.. Perhaps a bit overkill ?? The V9958 is cheaper to source than the TMS9929/18 , V9938 or V9900 and is probably good enough. Sound Chips YMZ284 DIP16 KC89C72 D...
