Has anybody else met with this and overcome it I'm fairly new to UI programming on Qt, so there may well be a simple thing I have missed.Also, this is a known problem when the DRAM chips are changed for another type, then different value resistors are needed. Second, if the value of the "isolating" resistors is too low, the two sections of the data bus may interfere with each other. So it's not worthwhile damaging a good ULA. There is a modern recreation, but it's currently only available in very limited quantities from one person. Two reasons: Replacement ULA chips are no longer available.
Logicworks 5 Pal Wizard Forum Tv Arena BijeljinaHowever, real +2A machines with a real +2A PCB are rare (a +2A PCB is really a +3 PCB with the disk drive chips and components missing and the cassette parts fitted). It has a black case and looks the same as a grey +2 except it uses a PSU that outputs +5V, +12V and -12V via a DIN plug, which of course fits in a DIN socket on the +2A. The new model is often called a +2A. Which is based very closely on the issue 6 48k Spectrum.Then Amstrad redesigned the +2. Mcdougal history textbook pdfIs that not something that can be fixed via modification of any kind ?I'm not 100% sure, but I have a theory (currently untested).It looks like the keyboard signals into the ULA derived from the CPU address lines (A15-A9), but there are also diodes in the way (D1-8). This has completely separate busses for the different RAM banks.It does have black case and a 6-pin DIN Power connector.In terms of the keyboard issue what is causing that. Instead it uses a Amstrad designed gate array. Note that some +2 black cases are marked +2B.The reason this is important is that there is no ULA in the +2A, +2B and +3. This is smaller than a +3 PCB and has no provision for the disk drive circuitry. The port is being read when it shouldn't be as the ULA is updating the screen at the same time. With regards to the rdio command the reads change each time I run it but I'm pretty sure this is all related to the Contention Management working differently. But that would probably also affect the keyboard ROM routine.From the ICE if you use the rdio command can you see examples of unreilable port FE reads?I wonder if this issue also exists on the Spectrum +2, and it's just I haven't tried loading any games.What's the simplest way for me to reproduce this?One more question - would unreliable port FE reads affect tape loading?I think all the levels are now okay as tape loading works successfully which would be an issue otherwise. The keyboard is fine upon boot up as it is only read by the keyboard routine in the ROM during the vertical sync flyback when the screen is not being updated by the ULA.Anyway just thought I would post the latest status.I did wonder if for some reason the levels the ULA puts out when port FE is read are still marginal, even with the pull ups removed. This all points to timing around how port FE is being read or maybe something to do with the CPU contention management affecting the T80 differently to the real Z80 i.e. Free microsoft office 2018This all seems incorrect though as surely other projects using the T80 would have problems with IO ?I don't think the +2 will have problems as I don't believe it uses the same contention management but it would be nice to know for sure. This timing is critical as the Spectrum uses this ORed with A0 as a low signal to read/write port FE.My plan is to run a logic analyser on it at some point and compare to a real Z80. My theory (which is probably way off ) is the T80 is updating the IORQ line slightly differently than the real Z80.
