Anyone have an Epson HX-20?

Recommended Posts

Okay, this one has me curious now. Anyone have one of these?
The display is obviously tiny, but it has some other features I'm interested in.

I have one that I picked up at some thrift/estate/yard sale at some point, but it's never worked and I keep it around just because it looks cool. Mine has an expansion box called RealVoice and there's a sticker on the back that warns about properly attaching the unit to a wheelchair so it must have served a disabled person at some point.

 

Beyonds that, not much I can tell you.

I have the successor called the PX-8. Built like a tank, the screws in that thing could hold up a door frame. Also, if the NiCAD batteries are completely drained it won't boot at all. It cannot run off of A/C power. Also, the micro cassette works like a floppy, and if memory serves can hold 12 files totaling 60K.

I was interested because of the 6301, which is an enhanced version of the MC6801... which is the same instruction set as the 6803 that I've been spending a lot of time on.
The PX-8 looks like a much nicer machine btw. I'd love one of those. Can't afford it at the moment.

I had an HX-20 aeons ago, complete with printer and microcassette drive. Unfortunately, it's long-gone, but here're my recollections of it:

 

They're a neat machine from an historical perspective, but overall practicality is somewhat limited. There's almost no original software available for them. The keyboard is better to use than it might at first look with a nicely-readable non-backlit LCD. BASIC is built-in and is a variant of Microsoft BASIC, IIRC. I think there may also have been a monitor mode akin to the one in the Apple ][, but that may be my memory playing tricks on me.

 

They're really a product of their time - and by that I mean that they're representative of trying to figure out what usable mobile computers would look and act like. That's not to knock them, but if you're interested in them I'd recommend asking yourself if you want it because of its place in the history of computing, or because you want something to use and enjoy regularly. If your answer is the former, you'll probably be better off in the long run than if it's the latter.

I'm pretty sure I have no intention of using it other than playing around with it to see what the hardware was like.

The screen is tiny.

I have a Laser PC4, and I'd like a PX-8... just cause

I have my Dad's old one which has been stored securely in a box with all the manuals, extra ribbon and power adapter.

It doesn't have the carry case.

Anyone want to buy it?

I never had one personally, but back in the 80's my Dad brought one home from work along with a digital scale and we worked on interfacing the computer to the scale to do data collection.

Hello,

 

Yes, I syill have one of these - HX-20.   I bought mine new back in 1983, had it ever since.   Still just about works, but needs some help here and there.   Bit like me, I suppose!

Cassette drive no longer works, so I save/load to the laptop (.WAV files) which works well.   Use 'hxtape' to manipulate the saved files, incl convert to .BAS or .TXT source listing, etc.

Lot of the machines about, and working.   Quite a community of users.

There is a YouTube video about the BOMBER (aka BLITZ) game for the HX - I was searching for a copy of this game.

 

Finally contacted the original author Simon Taylor.   He had the game on a microcassette, but the recording was degraded and he could not extract it.   But he kindly sent us the tape, and we were able to 'recover' the program with help from Audacity, the game is now working, and available as a .WAV

also on the site some details of the recovery process, plus other info about the HX-20

I had a HX-20, my mom bought it from a surplus store around 1988, and I remember taking it with me on a class trip and printing out fake biorhythms for everyone.  I've sure it's still around at my parent's house, but I think it wasn't working last time I checked.  It could be a NiCd problem, although I also suspected that I'd zapped the EPROM that's accessible behind an access panel.  Now that I know how to fix such things, I'll have to get it out on my next trip home and see what shape its in.
