    TashTalk: Single-Chip LocalTalk Interface

    Six units are assembled; I hope to have the rest done tomorrow... Also - I made a logo... it's a little simplistic, but it matches the aesthetic of the era...

    TashTalk: Single-Chip LocalTalk Interface

    And we have a lift-off! At, uh, three minutes past the hour... 😉 Now that I'm getting traffic flowing, I'm confidant with soldering together all the other boards. Soon, I'll be contacting everybody who expressed an interest in one via PM to arrange for header selection, PayPal, and shipping.

    TashTalk: Single-Chip LocalTalk Interface

    HD20 mode, for whatever reason, was hanging. I suspect it was trying to access the non-functional SCSI hard disk and waiting forever for a response that isn't coming. My next step is to remove that hard drive from the SE and see if matters improve.

    TashTalk: Single-Chip LocalTalk Interface

    Yup. I'm afraid this HD20 is now wall art. Going to need to use either a SCSI2SD or BlueScsi. I've tried turning on LocalTalk with the 6.0.8 boot floppy image that's on the FloppyEMU's SD card; but it doesn't seem to be generating anything on the printer port. As there's nothing in the Chooser...

    Introducing (and interest check) AirTalk: Wireless plug-and-play LocalTalk dongles

    Uhh... well... first, the disclaimer: everything I know about hardware design is self-taught; so it's quite possible that I'll miss something obvious to a real electronics engineer... but... The schematic looks OK to me... obviously, as you have a couple on your bench working, it's at least...

    TashTalk: Single-Chip LocalTalk Interface

    General Update: Currently trying to get a classic Mac with LocalTalk running. The IIvx I bought last year started up three times (good chime, and it was accessing the drive; but I still haven't found a setting on the D-sub 15 to VGA adapter that I have that makes it put out video compatible...

    TashTalk: Single-Chip LocalTalk Interface

    OK; I think I'm probably missing a step on the RPi side... Wireshark shows that I'm successfully generating LToUDP packets; and I know that the RPi is on the same network and talking because VNC from Mac OS X to the RPi works. However; launching tashtalkd generates no console output; and both...

    TashTalk: Single-Chip LocalTalk Interface

    Got a few more spare minutes tonight... Well, the good news is that the magic blue smoke is still in the epoxy IC packages... I still need to dig out my oscilloscope to see if the signals on the board are behaving, though... also need to setup a machine in here that has a LocalTalk port...

    TashTalk: Single-Chip LocalTalk Interface

    PicKit3 arrived, and is now successfully talking to MPLAB; and has programmed the first PIC12F1840. The first hat should be done; I'm planning on testing it tomorrow (er, later today - it's 4AM, and I really need to get some sleep).

    Development of Nubus graphics card outputting to HDMI?

    FWIW, my plan for NuBus was to use a XC9572 for bus interfacing...

    TashTalk: Single-Chip LocalTalk Interface

    Finally got a few minutes for myself, and... my PicKit 2 won't talk to MPLAB. So, I've ordered a new PicKit 3 off of Amazon; should be here sometime wednesday.

    TashTalk: Single-Chip LocalTalk Interface

    Thanks all for the sympathy regarding Maria. She is, and will continue to be, missed. However, I do have some GOOD news for a change! I finally got a chance to do some soldering and have the first one assembled and cleaned. It's at the moment untested, but I hope to get to that soon. I gotta...

    TashTalk: Single-Chip LocalTalk Interface

    There’s going to be a bit more delay. We had to put our kitty to sleep this morning at the vet after she started hemorrhaging internally; and I just don’t trust myself with a hot soldering iron right now. I’ll let you all know when I actually make some progress.

    New CPU Accelerator options for 68K Macs?

    Verilog sources for the FPGA/CPLD firmware will be available once I've tested them to be sure they actually work. Note that this may be a while! The level shifting is handled by the XC9572/XC95144 CPLDs - they output 3.3v levels which are TTL compatible, and are 5v tolerant.

    New CPU Accelerator options for 68K Macs?

    I don't have any experience building an accelerator per se; but I am (slowly) working on a FPGA project for PDS, NuBus, and PCI slots. My design involves several Lattice FPGA chips and a Xilinx CPLD (XC9572, or for PCI, XC95144) to do the bus interfacing. The Lattice chips are mounted on a...

    Missing SE/30 SCSI Controller Chip

    Faster in this context translates to the chip being able to support a higher clock rate. However, the SE/30 does not supply that higher clock; and I think that it wouldn't be easy to get it to do so. It's been months since I looked at that datasheet, but IIRC the difference was only a few Mhz...

    TashTalk: Single-Chip LocalTalk Interface

    Japaneese, actually. We picked up a used Lexus ct200h a few years ago for almost nothing considering that it was in practically mint condition; and this battery issue is the first problem we've had with it (I don't really blame Lexus - lead acid batteries can go bad all by themselves, if it...

    TashTalk: Single-Chip LocalTalk Interface

    Well, the good news is that the PCBs have arrived early, and look OK. The bad news is that everything else in my life has gone sideways all of a sudden, and I'm starting to wonder if I'm in a handbasket and where it's headed, if you know what I mean. This might delay production & mailing. If...

    TashTalk: Single-Chip LocalTalk Interface

    Well, it's all up in the air now... literally. DHL says the PCBs have departed Hong Kong, and gives an estimated arrival of the 27th, here. The female headers (stacking and regular) have arrived; so the only thing I'm waiting on is the blank boards themselves.
