As best I can tell it's a software limitation. I've found reference to a couple RTOS' around supporting hubs and the stm32f4, although I wasn't really looking for an RTOS, so didn't dig that deeply. I've also found reference to some commercial stacks that support it. I'm using the ST sample...

I've been hacking around with the pre-adb, adb, ps2, and usb keyboards and mice for a bit and was wondering how much interest there actually is for various adapter bits. PS2 to pre-ADB The PS2 mouse and keyboard to pre-adb seems to be working OK for me. I've got the pcbs and components to...

Now with mouse support!

Favorite in what sense? You can probably gather more about the people answering this poll than about the various machines. When I tend to pull one of these machines off the shelf, it's usually to actually use it for a specific purpose. From that perspective, the functionality of the machine...

The security of it is entirely situationally dependent, I think. Personally, my appletalk network is considered insecure to begin with, and the distinction between guest access and cleartext or twoway random for legacy access isn't enough to bother (and arguably less secure than guest), so I...

The IIfx PDS is a bit odd. Ignoring the pinout issues, there are 3 different ways of using the PDS: 1) You can map your card into normal slot/superslot space and you'll get 10MHz accesses with a clock provided on the PDS slot 2) You can map your card into special address space and you'll get...

On my raspbian system, appletalk isn't configured. It's not compiled in, and not available as a module. netatalk uses the kernel's appletalk implementation, which in an "embedded" system like rpi could be seen as extraneous and left out. That'd probably require a kernel rebuild, or at the...

I use netatalk (2.2 series) extensively, so if you have any questions I'd be glad to try to help out. It's about the only thing that will work from system 3.3 through to the latest OSX. To allow guest access, you need to enable the guest UAM module in afpd.conf. I use the following line in...

JFYI, when ordering from bomarc, he prefers to do things in relatively small batches. About 20 pages or so per order. He's an interesting guy. He does it old school, running off each run on the xerox machine and taking them to the post office, complete with what appears to be a typewriter...

I've contemplated this for a while, and I don't really have any solutions to offer, here's a few thoughts: Most of the older mail clients do not support SHA(anything) SSL certificates, which most people have moved to since MD5 based certs are old, and there's evidence they have been...

It's a 25MHz 020. The LCII had a 16MHz 030. This card is faster. The 030 added MMU, burst mode, an addition 256bytes of data cache, and a slight increase in instruction execution time ("more done per clock cycle"). For most users of the LCII, the MMU wasn't used, the LCII's memory controller...

Nice! I'm glad you got it working, and thanks for sharing. It sure helped me.

I've got my Fisher-Price My First PCB in. It works, but there's some rough edges to it. The PCB is made to use those level converter breakout boards from adafruit. They're about $4 each + shipping, and there's 2 on here. I've tried one without the level conversion, since the GPIOs are 5V...

I'm traveling for a couple days, so I apologize for the infrequency of my posts. The test is loading the loop count, then issuing a DMA NOP command to load the count and read it back. Since the DMA is a NOP, there should have been no bytes DMA'd, so the count should be the same. The DACK/...

Yeah, with it varying on the MSB like that, I can't really think of anything else but the actual scsi controller for bus1. :/

As best I can tell, the leading 0x02 indicates this was a problem with the high byte of the 53C96's transfer count register. From the 53C96 datasheet, the transfer count register is for DMA operations where you specify the number of bytes in a DMA transfer. The test loops, starting at 0 and...

Nice! I'm going through the code, there's no real documentation on this AFAIK, so it's a bit time consuming to decode. Here's my analysis of the tests as I understand them so far: 0x84-0x86 are SCC tests. 0x87 is a VIA test 0x88 is a general SCSI test 0x89 is Sound 0x8A is PRAM 0x8B is...

Nice! Was the machine already in diagnostic mode, or did you have to do something to get it there? Can you try to do the following: *N008400010000 Then *R to get the return code. This will run "non-critical" test 0x84 one time. I believe there are tests 0x84 through 0xA0 here, but some...

Great, glad you found it. I'm pretty sure it's a null modem connection, and it's using 2 stop bits. A client set to 1 stop bit might still show most of it though.

After the RAM tests come a series of other tests: SCC, VIAs, VRAM, Egret, PRAM, SCSI, and SONIC ethernet tests. Unfortunately it could be failing in any of these and there's not really a good way to differentiate. On kind of a long shot, do you see anything on the Modem port if you connect at...
