Re: Sandy Electronics...
Hi,
A few months ago, i replaced the disintegrated original felt pads with self-adhesive pads made by me, but i am not satisfied because 50% of the cartridges fail to format. I want to replace the old ones with Dave's pads. What is the way to remove the old self-adhesive pads?

Re: Double 3.5 disk drive issue.
Hi I had a similar problem. Connecting line 34 to gnd (line 33) on the controller side worked for me and finally I can use my Micro P. disk system.

Re: Sandy SuperQBoard firmware.
I bend the pin 27 out of the socket and solder the a13 pin(A14) form the QL connector to it. Now it maps the disk interface firmware but not the TKII. I think it needs more modification the pcb.

Re: Sandy SuperQBoard firmware.
I have programmed an eprom(27c256) with 1.19 and TKII, but it maps only the TKII. I think that the Sandy Super Q Board issue 1 pcb that i have, is designed to accept only 27(C)128 eproms, because pin 27 and 28 are shorted(to Vcc). And i don't think that if i cut the trace between 27 and 28 pin it wi...

Re: Sandy SuperQBoard firmware.
I have a QL with the JM version firmware. I have read that JM version has a bug about the expansions cards and that bug is that it maps only one expansion card firmware. If this is correct then my QL will map just one firmware, the disk interface firmware or the TKII.

Re: Sandy SuperQBoard firmware.
So, in the first half (0000-3FFF) will be the Sandy Q Board 1.19 firmware and in the second (4000-7FFF) will be the TKII code. There must be the 4AFB header before the TKII code?

Re: Sandy SuperQBoard firmware.
You are referring about 1.16+TKII and 1.19+TKII. The original firmwares don't include the TKII code?
