1. I've got the following TS2068 software:
zxbruno · Sat, 26 Apr 2008 23:57
Multi-Draw 2068 1984 by Gary E. Ward
TS2068 Banner - looks like a home-made program
Blam - 1984 Riverside Software
Tech-Draw Junior 1.0 - 1986 Zebra Systems
Quiksilva titles: Xadom, Aquaplane, Cybird Assault
Tasword 2
Tasprint
I'm going through all my tapes and I may find more titles which say
'2068' on them. But if they're specifically for the TS2068 or not, I
have no idea.
If there's enough interest, I'll make .TZX files and upload them.

Absolutely. There are so few 2068 programs archived that any additional
ones would be cool to check out. I especially would like to see any
2068 games. Also, do those drawing programs make use of the hi-res
mode of the 2068?

3. Timex hi-resolution modes
M. Emrah Oral · Sun, 27 Apr 2008 08:51
Apart from a very simple demo I haven't seen any games or programs that make use of the high resolution screen modes of the 2068. Does anybody know of an online archive like World Of Spectrum, where I can download hi-res Timex 2068 games, programs and demos in TZX, TAP or similar format?

I have not seen any, though I have tried the February 1988 issue of "Byte Power" which can use high-res mode for text output (hard to read!): You can download it on the ts2068 yahoo group here:

The files section of (the web side of) this group is the best there is.
Hi-res games just don't exist: nobody wrote them, mostly due to the
commercial failure of the 2068 but also due to the fact that the Z80
doesn't really have the necessary processing power to do any sort of
hi-res full-screen action.

Phil

The Bally Astrocade (also a Z80 machine) has low-res graphics. The
arcade counterpart did have hi-res mode. Since the Z80 was too
slow to handle the hi-res graphics what amounted to a blitter chip
was added.
Without RGB, hi-res mode on the TS2068 is extremely blurry. That
could also be a reason why it wasn't used.
I imagine if anyone wanted to, a hi-res game, that didn't require fast
action, could be written. There must have been someone curious
enough back in the day to have done this.

The TS2068 was a failure in the US, but what about the more popular Timex Computer series ? Was any hi-res games produced for the TC machines ? Would those programs be compatible with a 2068 with ZX Emulator cartridge I wonder.

Being portuguese, I use TC2048, TC2068 and Spectrums between 1987 and
1995, and then moved to the U.S. Apart from a small demo that came
with the Timex computers, I never saw any software that used the
high-resolution mode. Everyone who had a TC computer used Spectrum
software, and everyone thought the high-res mode was ugly and
unnecessary. The true potential, afaik, was never explorer.
It wasn't until a few years ago that I found Johnny Red's website, and
learned that Timex had released some Timex-only software and some
other rare computers and hardware. But nothing about the high-res mode.
I haven't used any of my TCs in years, but if I'm not mistaken, trying
to use the extra columns in BASIC while in high-res mode was useless.
The BASIC editor still behaved as if only 32 columns were available,
and any word printed on the screen would be printed 'l i k e t h i s'.

Not if you use the Basic 64 (tape) or OS 64 (cart).
There is also a word processor MTerm-II that uses HiRes mode.

12. Timex hi-resolution modes - CP/M
M. Emrah Oral · Mon, 28 Apr 2008 02:55
If the TS2068 could run CP/M the hi-res mode would be more meaningful I guess. The problem is the screen file would take so much of the 2068's tiny RAM that there would barely be enough memory for programs to run under CP/M, right?

As you can keep running the screen while the DOCK or EXRAM memory
banks are paged in, you can have the full 64kB address space available
with a RAM module plugged in so I think you could have good CP/M
support if you added 32kB RAM along with the disk interface (to
replace the ROM and screen area with RAM).
It would still be a bit slow scrolling and drawing the screen though.

Yes I think so, the hardware is as capable as the Spectrum +3 which
did have a CP/M, barring the missing disk drive and "shadow RAM".

I think that for the 2068 to run CP/M on it's own it had to have 64K
RAM only for CP/M (CP/M mininum RAM?).
The 128K +3 ZX Spectrum have a full 128K of RAM so it was very easy
to run CP/M on it.
For what I know, Timex Portugal was able to use a Timex computer to
be used as a CP/M terminal running a Terminal Emulator on the Timex
2048/2068 and running CP/M on a FDD3000/FDD3 with 64K RAM. It used
the 64 columns screen mode.
You should have a look to ZXVGS from Jarek. I think it is CP/M
compatible.

I have no clue, unfortunately. I've never run CP/M on a +3, so I don't know
how standardized the implementation is. In theory, there's no reason it
shouldn't be able to run. Most of the stuff that I have and/or have seen
converted to 40 columns were the Infocom games...

required 64K as the minimum/standard. While I'm a CP/M enthusiast and have
countless systems that run it, I don't see a particular advantage to running
it on the 2068. By the way, 40 column CP/M worked just fine on the C-64 and
particularly the Coleco Adam, where a lot of software was reformatted to fit
the screen.

Subject: Re: [ts2068] Timex hi-resolution modes - CP/M
I think that for the 2068 to run CP/M on it's own it had to have 64K
RAM only for CP/M (CP/M mininum RAM?).
The 128K +3 ZX Spectrum have a full 128K of RAM so it was very easy
to run CP/M on it.
For what I know, Timex Portugal was able to use a Timex computer to
be used as a CP/M terminal running a Terminal Emulator on the Timex
2048/2068 and running CP/M on a FDD3000/FDD3 with 64K RAM. It used
the 64 columns screen mode.
You should have a look to ZXVGS from Jarek. I think it is CP/M
compatible.

22. RE: [ts2068] Timex hi-resolution modes - CP/M
Luis Alberto D'Ardis · Wed, 30 Apr 2008 00:15
about cp/m and hi-res modes i don't think +3 could do anything or to take advantage of this, because the ULA is not the same thing in a ts2068 compared with a zx 48k spectrum and +3 video is based on this british zx spectrum.
if i'm wrong please someone correct me.
regards.

If you are still having trouble with the conversion, post a WAV of the

Thanks! If you could reach me by e-mail, I would appreciate. Together
we can try to preserve and share these tapes.
And speaking of preservation, I've started scanning the following books:
-Powerful projects for your TS2068 (can also be used on the TS1000/1500)
-The Best of Sum
Once these are scanned, I will post several links and share them.

Bruno isn't having much luck accessing yahoo at the moment, so he
asked to point out that 'The Best of Sum' is now available at:
