Hi, I have an Apple II that was a barn rescue. It was filthy, but cleaned up nicely and after a couple minor board repairs, works great. But I have a question about the power supply. Does anyone know the deal with this all black power supply (see pics). Was it an aftermarket replacement...

So working off of the Allegro thread https://forum.vcfed.org/index.php?threads/seeking-allegro-common-lisp-3-1-for-nextstep.70048/ I have a couple questions. I made a little progress on finding some Lisp software. Another user kindly pointed me to floppy disk images for Allegro CL at...

I have an Amiga 2000 with 3.1 installed. I have a Data partition where I've been installing some Fred Fish software. I install each from an LHA into it's own drawer on the Data partition. It works and I'm not having much difficulty with this other than the icons and other files in the Drawer...

Hi, I have an Osborne 1 that I've been working on for the last few weeks (single density...no DD mod). I don't have Osborne floppies, so thought I'd install a Gotek and once that works, I can make my own floppies. Several weeks later and I finally have a working Gotek from which the Osborne...

I have an OCC1 that powered on and requested a disk. I don't think I have the correct floppy for it (should a Kaypro or Northstar disk work?). Anyway, that is a secondary issue at the moment. The floppy drive seemed to do nothing but spin when I put in a floppy so I opened it up to look...

Hi, I'm wondering if anyone has advice for putting a solid state SCSI HD in a Mac IIfx and copying the current drive to the new drive? I have an IIfx with a Barracuda 4gb SCSI drive (ST15150N). The machine is unique in that it has a MacIvory 2 card stack and a Genera 8.3 install on the drive...

I recently installed a BennVenn Lynx(II) Drop In LCD Kit on my Lynx. Very nice screen upgrade for a reasonable price. I bought the soldering required version. If possible, for the extra $10, I'd recommend the solderless version. But if you're comfortable with an iron, it's no more than 20-30...

I fired up my 4P yesterday after a couple of years of inactivity and let the magic smoke out. Interestingly, it continued to work fine for the couple of seconds it took me to get to the power switch. I opened it today and it looks like the .22uf capacitor on the high voltage board split open...

There's a version of Life on the Apple 1. I have it on the CF card on my CFFA...can't remember where I got the software on the card, but it's in the MCODE directory, if anyone is familiar. I believe it's a fairly common distro of software for the A1. Anyway, I'd like to use the Life program as...

I picked up a barn find Apple ][ on Craigslist a year or so ago. It cleaned up pretty nicely. Has a few issues I'm working on, but wondering if someone can give me some info on this ROM card. It came in the A2 when I got it. When installed with the switch up, it boots to integer Basic. I...

My model 1 display is wavy (see video). It gets progressively worse as I use it. After about an hour it gets pretty bad and is worse than shown in the video. I’m a bit nervous working around CRTs so wanted to see if anyone knows what might be causing this, too minimize my time messing around in...

Hi, I have a WIFI232 that I'm trying to get working with my TRS-80 Model 1. I have the serial board in the EI and level II. For the most part, I think everything is working ok. After messing with LDOS 5.3.1 for a day and finally discovering that when you load the RS232R driver in LDOS 5.3.1...

I recently picked up a 1040STF that included a second floppy drive and a hard drive. It seems to be fairly complete, but I have no experience with these machines. So far I have only been able to get the GEM desktop to come up. It's not able to read anything that I put into floppy A (the...

I'm rebuilding an HP-41 card reader due to the "gummy" deteriorated card feeder roller. It's working about 50%, but I'm having an issue, I think, with the part outlined in red in this pic. http://imgur.com/Q2QhwMy This piece is flopping around somewhat loose and I'm not sure how it should fit...

I recently picked up a Sharp 19SV111 NES TV and of course, it's missing the remote. Does anyone know of a replacement (programmable) model that will work with this TV? Simple on/off, channel and volume would be sufficient. Thanks...Win

Hi, I'm looking for a scan of the Math ROM Module (5061-7226). I checked the hpmuseum and bitsavers sites mentioned in the text module thread but did't see (or couldn't find) anything. Anyone know of a source? Thanks, Win

Hi, I have an HP-71b with a text editor module. I'm able to launch the editor and get the "cmd?" prompt, but other than inserting and ending, I haven't made much progress. Does anyone have a manual or command summary for the text editor module? Thanks...Win

I recently picked up a Scorpion robot kit...uses a 6502 single board computer that comes preassembled. It looks to be mostly complete except for the software. They had a mailer that you could send in to request IBM, Apple II or TRS-80 software. It was never sent in and I doubt I'd get a reply...

Has anyone successfully installed Xenix on the Lisa using an X/Profile as the hard drive? I downloaded the Xenix boot and sys disks from the bitsavers site as referenced in this thread http://www.vintage-computer.com/vcforum/showthread.php?3582-Anyone-ever-seen-Lisa-Xenix I did not have any...

I recently got one of my two Lisa 2/10s running (by scavenging from the second one). The it was not booting from the Profile drive, although the Profile was behaving the way it is supposed to. It also would not boot from the internal Widget...the Widget did spin up. I have an X/Profile drive...
