Additional clockports for the A1200 ?

[Doobrey]

@JJ, Don`t wanna burst your bubble, but did you read on a few posts after that ??

@Meth, don`t worry..the FlashRom design has a built in splitter.
 BTW, I hope it hasn`t got anyones hopes up, but I won`t be selling anything. I`ll post the PCB designs and any needed software on my site when it`s ready. If a muppet like me can solder, I`m sure others can too :-)
 I was also thinking along the lines of an extended clockport..having a 16bit datapath and maybe an extra address line or two.  
 No use for existing cards, but could be handy for other people designing stuff.
 Any hardware hacker types got any ideas/thoughts about it?

@Doobrey

Stop pissing about, make an extender/adaptor board for the CPU slot, then you have a 32 bit, 14 MHz bus to play with!

It has _RTC_CS, _NET_CS and _SPARE_CS. What does the _BEER signal do?  :-)

Failing that, the two kickstart ROMS have the Address and Data bus of the 68EC020.

@Methanoid

Once there was the Quadroport clock port expander. There are designs posted in this topic but not tested.

Have fun.

GAH.. typed this out,just about to hit submit and ####ing BSOD  :pissed:

_BEER tells the CPU that a bus error happened during the current cycle, and depending on _HALT, the CPU either retries or generates an exception.

Anyway, put yer handbag away Stedy..

For what I have in mind, tapping direct into the bus is overkill, sure for a decent network card it`d be the best option though.

As for the rom signals..where do you think my flashrom fits?
Unfortunatley,it blocks access to the clockport (actually the stripboard version blocks most of East Anglia :-o), so I figures that since I was gonna extend the signals to a header on my board, I might as well split it.
