    [C64] RS232 userport adapter works but gets hot

    interesting well I don't think I want to make a twitter account just to reach out to him I'd rather just stay out of that whole universe. So nothing wrong with the caps as far as I can tell. One interesting bit I tried powering the device with a bench power supply (so it's not in a c64, just...

    [C64] RS232 userport adapter works but gets hot

    Yeah I'm basically using this broken piece of tech as an excuse to practice and improve my own skills, I have other means of connecting my Commodore so for me the end goal isn't so much having a working rs232 adapter as I could just go buy another one it's to get this one in particular working...

    [C64] RS232 userport adapter works but gets hot

    I've had this device sitting around for years and have rarely used it. The reason is that it gets really hot, well U1 (one of the MAX232CPE chips) gets hot. Like hot enough that you can smell it burning and if you touch it you burn yourself. U2 (which is the same chip) is fine. I tried swapping...

    Amiga 500 gotek external drive

    My first attempt I had nothing on the drive except for the two ADFs, when that was giving me the E31 errors then I went down the route of adding the HxC stuff. For now I'm booting off of a floppy (workbench) so I'm not really concerned about booting off of the gotek just yet. Once I get it...

    Amiga 500 gotek external drive

    Ignoring the add-on to swap DF0 and DF1 for now (until I know this is working) is there some trick to setting up the thumb drive for a gotek that will be on an external floppy drive on an amiga 500? I copied the files HxC_Compat_Mode/Amiga/AUTOBOOT.HFE and HxC_Compat_Mode/HXCSDFE.CFG to the root...

    Amiga 500 : IDE hard drive (CF Card) issues

    Well I got the Kickstart 1.3 rom installed okay and went through the process again but the result is the same, after formatting I still get "Not a DOS disk"

    Amiga 500 : IDE hard drive (CF Card) issues

    Yeah this will be the 3rd card I've tried, I have a 4th on order (a 256mb SanDisk) This is the first one that would actually go through the format process. I did get out of memory errors with a 64gb card and my 8gb hard drive. As for ram this is a bone-stock Amiga 500 except for an internal...

    Amiga 500 : IDE hard drive (CF Card) issues

    You know what I think I might know the issue, I'm using Kickstart 1.2 which I think predates compatibility with FFS (Fast Filesystem). I will try updating to 1.3.

    Amiga 500 : IDE hard drive (CF Card) issues

    Taking a long shot there that someone might have some answers but I'm pretty much at my wit's end. For my (stock) Amiga 500, I would like to add some storage. I found and put together this: http://nuclear.mutantstargoat.com/hw/amiga/a500hdd/ The memory card I'm trying to use is a SanDisk...

    486: XTIDE Universal Bios not loading on startup

    Update: yeah definitely a cache issue, I might need some help there too but I'll post that question separately since the subject line on this is about XTIDE.

    486: XTIDE Universal Bios not loading on startup

    Alright it looks like I have a completely separate issue. I removed as much from the computer as I could (kept video card and floppy/IDE controller card) and connected only one floppy drive (no hard drive) and tried to boot off of a floppy. This still locked up just after POST. This...

    486: XTIDE Universal Bios not loading on startup

    I have had for the past few years this 486 (a dx-33) which has been relying on the XTIDE Universal Bios (sitting on a rom chip in a network card) to support the hard drive in the system. The hard drive is an 80 gig drive but is recognized as an 8 gig drive and I have currently 2 2-gig partitions...

    Midwest WTS: Atari 800 Mechanical Keyboard

    Hi all! Last year at VCFMW I picked up an Atari 800 and in restoring it I was faced with the issue of a broken, pretty much non-repairable, stackpole keyboard. I found this Mechanical Keyboard and decided to go that route as it lets me re-use my keycaps and keep the same classic look to the...

    Writing ZX-81 Basic on PC?

    Actually that sounds exactly like what I'm looking for! Thanks, I'll play around with this today!

    Writing ZX-81 Basic on PC?

    Hmm the physical key-presser sounds interesting but I was thinking I would run my code incrementally through an emulator as that would make for a faster turn-around with testing and only get it running on a real zx-81 further down the road after it's pretty much done.

    Writing ZX-81 Basic on PC?

    Hmm maybe but I do want my program to run on a zx-81, not a spectrum. If necessary with a 16k ram expansion.

    Writing ZX-81 Basic on PC?

    Hi all I'm looking for a way I could try writing a simple basic program for the ZX-81 on a PC (maybe just use notepad++, or notepadqq in my case since I'm using Linux) and then something that will convert that to the tokens the ZX-81 would be expecting and make a file I could put into an...

    PETTerm (or wimodem) double key when using shift.

    I don't know if this is a petterm issue or an issue with my wimodem (from cbmstuff.com) as so far I haven't been able to find another term program that I can get to work. I have a PET 8032 with a business keyboard. I'm using "petterm80b". whenever I use a shifted key like an upper case...

    ZX-81 Project, ram expansion help

    Not a bad idea, but there should be plenty of room in my wooden case for it as it is given the top needs to support one of those portable TVs (I'm hoping I can find one with a composite input or figure out how I can feed a composite source to it) Right now I'm working on a video inverter circuit...
