Re: QL Network Protocol(s)

Hi, With all the variations of the net protocol, it would be very nice if someone with the knowledge could create a table (in excel or other) with all version of the driver (BBQL, TK2 VXX, Minerva, SMSQ etc, including the zx spectrum) in both row and column and, at each intersection, a list of what ...

Re: My Gold Card is faster than yours! Well nope it doesn't work.

Thank you Marcel for your inputs. I guess this is yet another project in the list of "to do". But if I want to modify the Minerva ROM, first I need to buy an eprom programmer.

My Gold Card is faster than yours! Well nope it doesn't work.

Hi, I came across a few 68010 chips and installed some of them in my amiga 1000 and 500. I got an instant 5% to 10% speed boost from the better optimized 68010 instructions. More specifically 9,5% boost on my prime number benchmark (see the thread in the hardware section for more information about t...

Re: Two peripherals attached to Q68 fried at the same time. Coincidence ?

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...

Two peripherals attached to Q68 fried at the same time. Coincidence ?

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...

Re: Poll: CPU choice

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.

Re: 8302<>8049 communications...

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...

Re: TF Services Interfaces and BBC Micro:bit

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...

Re: The QL and the 16 bit revolution.

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...

Re: Q68, QL-NET and I2C

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...
