Re: Gold Card Battery
Provides battery backed clock and a few unused bits in RTC chip hold settings for AUTO_TK2F1 (boot automatically as if you pressed F1 with TK2 extensions enabled, AUTO_TK2F2 for F2, AUTO_DIS cancels). Also SCR2EN/SCR2DIS for second screen and FLP_JIGGLE (fix for some drives). IIRC only 4 bits, but C...

Same item in UK
Edit: (to save another post in this thread). I find Amazon's search for products useless, too often I only find what I want when I do it in a roundabout way.

Re: Q40/Q60
It has been said that OSSC converters can provide that, if they are well tuned. But one has to be careful about the various variants. Also I find them clumsy and expensive. I have tried OSSC and gbs-control on Q60 and I could not find a setting on either that would successfully display the full Q60...
Re: Q40/Q60
For those cRaven something like a Q60 ?

Re: FPGA replacment for the ZX8301 ULA and more
PCEN peripheral chip enable. Surely any ZX8301 replacement will need to provide it for ZX8302 on pre issue 6 QLs (also TXOE).

Re: FPGA replacment for the ZX8301 ULA and more
I'll reconsider the expansion port but new pcb from the begining and new tests ... : :cry: Ah, it was only theoretical question not practical. Your achievement this far has been tremendous 8-) I have to admit that there is a problem with those red tall cpu sockets They are very flaky, easily splitt...

Re: FPGA replacment for the ZX8301 ULA and more
Curiosity has got the better of me so please excuse naivety. Re using expansion bus:
For issue 6 the HAL deals with PCEN (pcen = a16 * /a17 * /a6 * dsmc)
On issue 5 and earlier, wouldn't it be possible to drop in simple decode board for PCEN and TXOE (ZX8302).
