Thanks Peter and all. I guess this is a good lesson learned for me. Always make sure the power supply cannot fall into limited current mode. I won't make the same mistake twice. Just loosing a keyboard is not too bad. Could have been worse. I have re-connected my new keyboard combo through the KVM s...

Hi, As the title says, my Q68 setup sustained multiple casualties that appeared to take place at the same time. The Q68 itself still work great. But I want to have expert opinions as to what might have happened and precautions I should take in the future. Here is the setup: Q68 powered by a HP-6623A...

Dave,

Do all 3 options allow a GC or SGC to be installed in the left expansion slot ?

I would buy your mother board if it become available (I have a lot of reliability issues with the original one) . But as I would install my GC, the internal memory amount is not important.

BTW - given recent experience re-working the QNET driver around Q68's hardware-timer, I can say that any 8302 replacement should have a high precision timer included - it would make any further QNET driver development soooo much easier... Imminent release of a new SMSQ/E for Q68 with QNET driver im...

Hi, The Q68 has a I2C interface on tge board, which I have fitted a SIL header. All Tony's Inferfaces can be used. The only problem is the lack of external I2C connector when the Q68 board is fitted into a case. The real only problem is that no driver exist yet for the Q68. Unless I missed them. On...

Don't forget the Hewlett-Packard line of 68000 computers. The first one, the 9826A, was released long before the QL in 1981. The HP Basic that was included with these computers was very fast and much more complete than anything available for QLs, Amigas and Ataris. As an example, a HP9816 with a 680...

Constant speed is not required for I2C, it should just not be too fast. There is very little SRAM, so it should only be used if speed is critical. I2C is low speed, so unless there are very special applications, normal SDRAM is okay. Ok, good to know. I get it now, data follow the clock signal, clo...

Hi, Hope to have some spare time during the holidays. On the program: using I2C on the Q68 and one day, the QL-NET. A few questions: I2C: From the Q68 user manual, I see that the two I2C pins can be controlled by writing bytes at address $1C1C0 and $1C1C4. I also remember reading that there is no su...

On an Atari TT030 (30MHz 68030) it takes 127 seconds. Unfortunately SMSQ/E doesn't run in fast RAM so I can't test it with the uncontended EDO RAM only the slow RAM shared with the video sub-system. But if we assume the code is so small it should run from cache, the RAM speed should not matter... A...

That's fast!
