Re: Epson HX20 - first laptop !EVER! 1981+

Noted. The enable instruction seems similar to the one for my board.

I assume the problem you have is that this facility is for release 4 or higher. You must have an earlier release, which does not allow the soft switching of the ROM. There's prob nothing you can do about that.

Re: Epson HX20 - first laptop !EVER! 1981+

Paul, Thanks for the update. Yes, I see references to the electrolytic caps in the HX. Some folks like to repl them anyway. Others refer to problems with the lcd display indicating that the caps need repl. The caps in mine have NOT been repl, everything seems to be working OK (apart from the hs seri...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello, Regarding the RAM board, please look at the documents on the web by Martin Hepperl - search for Hepperl HX-20 and you should go right to it. He shows two different German origin ram boards, and the one you picture looks VERY similar to the Type 2 he shows. He gives details of the Mfg, and som...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello, I've been in corresp with someone in Sweden, who I understand has been using the flashx20 system for a while. He reports that there seems to be a number of bugs and problems with the system, although he wasn't specific about all of them. Maybe the problems you've had are in the system, and NO...

Re: Epson HX20 - first laptop !EVER! 1981+

Yes, I think that I put the version there as someone was asking, but I later determined that they were really looking for the other version. Regarding the software, what sort of thing are you looking for if NOT BASIC listings? The machine was originally sold into a business market, and the bulk of t...

Re: Epson HX20 - first laptop !EVER! 1981+

Regarding the BOMBER game for the HX-20 - I am still in pursuit of this, trying to find the game, and I have a note that there are folks here who would like the game. I now know that there are two versions of BOMBER, quite different. There is a version written by William Smith, for Epson, and this v...

Re: Double sided, double density 5.25” PC disc drives

Always interested in compilers etc myself. Checking the photo you linked above, I note that you've got the docs etc for v.3.31 of MS Fortran for MS-DOS, which I discover is dated 1985. I've found a copy of this in VetusWare, and downloaded it. This comes as a .ZIP file, and when this is extracted, t...

Re: Double sided, double density 5.25” PC disc drives

Since the above, I've looked up about image files and DOSBox, and I see that DB allows you to load all 4 images together, and once active, to swap between them (using Ctrl-F4 I think). If DB recognises the image OK (.IMG file) then each image will see the complete disk, i.e. both sides of the floppy...

Re: Double sided, double density 5.25” PC disc drives

I still have a working PC with a 5.25" drive, it's actually a HD drive, but it will read 360k disks, and with a little care I can write them as well. I use this facility for working with CP/M disks, incl creating disks from images, etc. You don't say what drive facilities you have on your PC. I'd gu...

Re: Another broken computer: Epson HX-20

Jon, I'm a bit mystified about some of what you say about the screen. You say, or suggest, that you've been doing something in the Monitor. If this is working, i.e. giving you a useable screen, then the screen is OK? The Menu is constructed within virtual screen and then displayed, like everything e...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello Marcus, Maybe you've tried the save now, and it worked OK. You need a couple of mini (3.5mm) jack leads, and connect like to like to your laptop. The sockets on the HX indicate the destination, so it's mic on the HX to mic on the laptop. I used the SOUNDRECORDER application on my laptop, quick...

Hello Col, Further to ongoing discussion, have you seen mention of the FLASHX20 system. Try http://members.aon.at/nkehrer/ This looks very interesting, to attach a PC to your HX and, via the facilities of the PC, provide floppy disks (as per the TF-20) and full monitor access (via a sort of display ...

Re: Epson HX20 - first laptop !EVER! 1981+

Col, I've got a BAS program called HXDEMO, but I'm sure it's not the same as the one in the video. Some of the bits of the demo may be similar, some of the graphics things, sound (?), but there's quite a bit of text, and text printing. This prog is about 17k in size, so there'll be a problem unless ...

Re: Epson HX20 - first laptop !EVER! 1981+

Col, I'll look out fir another 'bomber' game. Or, I'll just need to re-write parts of the existing BOMBER game to create one. I'd guess that the 'City Bomber' has a similar plane/bomb mechanism, just that the game draws a 'city' on the screen as a target which is then progressively bombed (until the...

Re: Epson HX20 - first laptop !EVER! 1981+

Col, Just to clarify, BASIC and FORTH use the same RAM, esp the bottom of RAM for a lot of 'system' stuff. If you've been doing anything with BASIC, when you start FORTH and get the WARM? prompt you should say N (for No) which will allow FORTH to reset things as it needs. Else you risk all sorts of ...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello Col, Right, the other one you illustrate has the expansion unit attached, this may well provide extra RAM (to get you up to the 32k max) as well as alternative space for ROMs (I'm pretty sure the HX cannot have more than 64k of whatever/however. I've had some play with BOMBER. I don't know if ...

Hello Col, If the FORTH starts up correctly, you should get a screen something like: Warm? Regarding the Warm start (which assumes the state of RAM is OK). Proceeding from there should give: Copyright 1982 J.W. Brown EPSON-FORTH V1.0 The '0' your screen shows might be relevant, as this might relate ...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello Col, Your HX is clearly non standard. I assume it's one (one of many) that was modified for a specific vertical system, had special ROMs inserted (and I guess some standard ROM removed). Mine is (or rather was) a standard machine, bought new 1982 soon after they were first available (after rea...

Re: Epson HX20 - first laptop !EVER! 1981+

Hello Col, As for any .WAV files for the Forth (HCCS) - errm, I'd guess not. Certainly far from likely. However, do note that the HCCS implementation is very specific to the HX, and it includes support for the tape storage, both microcassette and external. So there IS a way to SAVE and LOAD regardin...

Re: Epson HX20 - first laptop !EVER! 1981+

Col, The good news is that I've converted both the text progs into .WAV files. Better news, both files loaded into the HX, and LIST seemed OK for each. BUT, both progs produce an error, so there's something amiss. In both cases, the error is a NF error, which is 'NEXT before FOR'. Looking at the cod...

Re: Epson HX20 - first laptop !EVER! 1981+

Col, Thanks for the message. I assume you've not (yet) tried to do anything with the FORTH? I'll get working with the conv of the two progs. This involves the software from the 'hxtape' project (php code), and also a bit of help from Audacity to get a suitable .WAV file. Once got that, can 'play' th...

Thanks for the SkiWrite piece. I attach the bin image of the HCCS Forth system. I have the manual for the package.

Did you get ther SkiWriter system sorted out - I downloaded the ROM files you'd posted, but cou...
