Where are you getting FORTRAN from? He mentioned Forth, not FORTRAN.

Assuming square pixels, 1024 x 864 gives a 32:27 (≈1.19:1) aspect ratio! That IS unusual. The traditional ratios – 4:3 and 16:9 – are about 1.33:1 and 1.78:1, respectively. I wonder what the rationale for that was? Looking at it differently, it’s 96 pixels taller than the usual 1024x768...

Well, the warnings about massive power/ground planes inside the cards were spot on. I couldn't get the blasted thing hot enough to solder-flow for the replacement caps, even when the entire card had gotten uncomfortably hot due to the inner layers wicking away heat. Luckily, the advice about...

Honestly, I would agree in many cases – but CRTs get _bulky_, and I just can’t justify the space one takes up if a converter that handles a given platform’s peculiarities exists. The Apple IIgs, for example, relies on side effects like phosphor bleed to generate colours, but two different HDMI...

The original Apple dev-support sample code was called “ShowInitIcon”, so yes, is a historical reference.

@trag, do you have gerbers, part lists, etc for this alternate design?

Alas, I cannot immediately test the fix out, as all of my LocalTalk-capable Macs are inoperable at the moment (which is why I had to do it at a Seattle Retro-Computing Society meeting the first time), but I am very impressed at how promptly you addressed the issues I encountered. To steal a...

I did type it in manually. I’m so used to the shell automatically expanding tilde notation that it didn’t even occur to me I might want to type it out the long way. So, oops. At least now you are reminded that’s a thing that can occur? My thanks for the very prompt updates!

I can indeed send you the log and the pcap! Because of obsessive completism, I had left the pcap running during the entire session; which involved trying to connect repeatedly from numerous old machines, all of which got the same error out of it – and if it was a permissions thing, that makes...

Well, I finally had a chance to try it out... and I think there may be an issue or two with the (Mac release of the?) software. Trying to connect to my Intel MacBook running Sequoia, from a Quadra 700 (admittedly, a heavily upgraded one) running OS 8.1, yielded only an error message claiming...

Home wiring is AC - you have a hot lead and a neutral return lead, and the ground is mostly just there for safety. Computer equipment uses DC, with a positive lead and a negative lead; by convention the negative lead is set at ground voltage, so you can both use the ground wire as the return...

My memory is showing its holes here. System Picker became less relevant once the Startup Disk control panel became a thing, becoming mainly useful for selecting amongst different System Folders on the same volume, but when did Startup Disk happen? Was that new with System 7?

My TashTalk USB board arrived the other day (very prompt!), and one of our fine colleagues in the Seattle Retro-Computing Society kindly printed me a case for it according to the supplied design files. Yesterday I acquired a suitable USB A-C pigtail cord – via Amazon (*spit*), sadly – and I...

I'm not likely to ever be in a position to find out first hand, but is it theoretically possible to directly swap the 7455 in one of those with one of the cooler-running chips mentioned above? Even at the same clock speed it'd net you a huge improvement in usability, just from the improved...

*boggle* I’ve used the web regularly from 1995 onwards and I somehow never ran across that one. …I think I’m glad, honestly.
