Declaring interest.

Has the AA3000+ routed the INT6 signal to the processor slot?

Oh... I just realized that my Acill A4000 has Super-Buster 9 while my A4000TX has Super-Buster 11. This is really interesting, since ReA4091 has a Super-Buster 11 requirement... Update: I now removed Super-Buster 11 from the A4000TX and soldered a socket to the mainboard. But neither...

Thanks for sharing. I was a little afraid to test it again, but I will give it another try :)(y) I have another problem... I built a ReA4091 which perfectly works fine in my Acill A4000 build with a BFG9060. However, I get checksum errors when using the ReA4091 in the A4000TX along with the...

Hi Bruce! Many thanks for your ongoing support and the interesting information about U356! I already have the FDN357N at Q301 and I found a new one in my IC box and had replaced it. Still had the same issue. I then replaced both CIAs and PAULA with known good ones, still same issue. Today I...

Yes that was my brute force attempt... ; p I guess the A4000TX is a "copy" of the A4000 CR ? So Q901 is probably related to IDE rather than the floppy circuit. I did not replace Q301 so far, need to check my box if I have a replacement. Also most probably no replacement for U356 (who knows what...

I just gave it a try. Using a standard Amiga floppy drive cable (with 4-5-6 twist at the end) with two Amiga floppy drives, one jumpered to DF0, the other to DF1. It worked, but it could maybe also be the reason why nothing works anymore now... no idea. The drives were both Amiga and I had the...

Hi. My floppy drive's motor suddenly stopped working. The floppy drive worked fine for several hours. I also connected a second floppy drive which worked fine as well (DF0 + DF1). At one point, I attached the floppy drive's data cable in the wrong direction. However, the stepper motors are still...

Yes, exactly.

Hi. I am offering 5x MC68060RC50 Revision 1 CPUs. The CPUs were relabeled to be revision 6 CPUs, but they are revision 1, all full-featured including MMU and FPU. However, I put the CPUs through their paces and they are all in pristine condition! Perfectly fine for any 68060 accelerator board...

I got myself two more PS/2 keyboards today. Both IBM brand and they work flawlessly... The other keyboards which behave strangely, are Siemens and Toshiba. I guess there are some slight differences in the protocol implementation. Would be great to make the ATMEGA88 code public at some point in...

I might have made some progress. Programming the ATMEGA88 with a single line and using 0xf9 for efuse, the PS/2 keyboard interface now shows signs of life: However, pushing the Caps-Lock key 5-8 times in a row, let's the ATMEGA88 somehow crash... Could somebody with a working A4000TX PS/2...

Really tried everything to make the ATMEGA88 PS/2 keyboard interface working... Are there any schematics from this part of the mainboard? Does someone knows if this interface was integrated from some known open-source project where I could get more information from? I am really desperate...

I now managed to program the PIC 16F84A with the K150 programmer by using a SOIC-18 to DIP-18 adapter and the K150 ZIF socket. In-system-programming was not possible in my case. The ATMEGA88 for the PS/2 keyboard interface still does not work properly. I programmed it with USBasp and the...

I am now trying to program the PIC16F84A for the PS/2 mouse support. I did the following: - Installed Windows XP to an old PC and installed the drivers. The PIC K150 programmer is recognized as "Prolific USB-to-Serial Comm Port (COM4)" device in the device manager (cp. attached image). -...
