I'm going to recap the LCD DC-DC in my Epson HX-20; It's pretty dim, especially when the battery voltage is what it should be; looking at the vLCD with a scope, it's getting nowhere near a smoothish 7v like the TmH says it should be. And at least one of the 10uF caps (c6) on it looks grungy at the bottom.

I've a "old #astronomy software" side project and I'm looking for the early Mac software "StarMap" or "Star Map" from Bruce Webster.
So far my searches came up empty, but I'm not a specialist in old Mac software.
Does anyone have a copy of this app?
It's described in detail in a July 1985 BYTE article: #retrocomputing

The Mac Centris is finally recapped, refurbed, and running A/UX. Now to play around with it. 😁

This is a comment I left on this video: #retrocomputing

How it started How it’s going
#retrocomputing

Well yeh that's why my Epson HX-20's 'charge battery' triggers - the detector input is indeed dropping below the 1.2v threshold with serial running (and microcassette connected albeit idle). So the voltage detector is triggering at the right voltage.
It could just be the lack of real batteries I guess, but hmm, getting there.

… or “liquid glass” gimmickry, for that matter.
But unlike what most replies suggest, this isn’t #CDE, this is HP-VUE, the ancestor of CDE.

«How to Write a Computer Manual» found by accident on one of my many wanderings through the internet. The half-title says “Jonathan Price and the staff of the User Education Group in the Apple II Division of Apple Computer, Inc.” The book was released in 1984. #vintagecomputing #retrocomputing

I think I found the problem with my Mac LC III's power supply...
Couldn't figure out why some things had lights (ZuluSCSI and network card) but not the system board. The yellow is the 12V connection...and it's corroded and broken the pin off. All the 5V stuff was working.
In a timely turn of events, the replacement pins and connector come today.

They look so nice and clean when they are fresh out of the post-recapping bath. No more dust or capacitor scum or flux. Almost like the day it came off the assembly line.
The Mac Centris 610 is mine and my son made the other two. I just washed them in alcohol to clean them up for him.

Today’s evening: first steps with @… on my vintage 32bit Samsung NC-10. #vintagecomputing #retrocomputing

Wahey! Success on my Javastation Krups, this is a Debian Sarge debootstrapped userspace running over NFS.

I was just sent this photo, supposedly taken in 1994: Björn Beutel, developer of the Malaga language, and myself are working in the CLUE (Computational Linguistics University of Erlangen) lab.
I’m a bit hesitant to tag this #retrocomputing ;-)

Some more Epson HX-20 observations:
a) Life was hard before self-contained DC-DC converters were available
b) 1300baud? wth would you do 1300 baud on the microcassette?
c) The 232 interface is ludicrously complex spit over the two CPUs.
d) The manuals are wonderfully detailed - although not necessarily consistent.

Table is finished and installed. Mac LC III has FINALLY been moved out of my office.

PSA: isc-dhcp-server >~3.0 sets the 'siaddr' in offers to 0 unless you set the next-server entry for a server; and Javastations don't like that. They used to set it to the server IP, like god intended.
(Yours after many hours of debug, bisection, tcpdump and reading the dhcp spec).
So if you're reading old config guides for old machines and using a modern DHCP server...

right, that's tidier: Replaced my breakout box, a 9->25 lead, a 25->9 converter, a bodged lead and 3 crocclips by a simple 9-pin null modem lead.
I need that breakout box for the next task.

The Epson HX-20 BASIC has the fun 'OPTION BASE' command; it lets you change if your arrays start at 0 or 1 !
(More HX-20 stuff may be coming, a friend gave me one he had a dupe of)

Progress! By running a #Debian sarge (2005) dhcpd my javastation now gets as far as wanting to tftp! Figuring out what modern dhcpd's do (even the isc one) is for a later date

I'm starting to play with an Epson HX-20; interesting little portable from the early 80s.
I've just figured out the tape has a file from August 1984. It's a basic file called TILL, now if I can get the serial working reliably I can dump it, but I'm having a problem of it complaining about battery voltage which seems common on it. Some playing needed.

It's June, so I've got my Javastation off the shelf for the first time in a couple of decades. This is a Javastation Krups, with 100MHz sparc, sold as a diskless workstation. I never realised it had a PPP ROM boot in! Anyway, I should get on and set up networking and a boot server.
(Note: the plastic on the clips on the doors is fragile, 2 just pinged off on me)
