Yes, that's correct. Over in the UK you had the Dragon, a neat little machine.

Just to help me understand better...when you refer to Cocos, do you
refer to the Tandy TRS-80 COlour COmputers?

A friend of mine has the following systems available for sale (he's not
a collector). Neither of us could really come up with a price, since
these systems are a little out of my line. The Sanyo is a Z80 (not to be
confused with the later MBC-550 which was an early 8088 MS-DOS clone).
Both are in full operating condition.
Altos 586
- 8086/512K
- Xenix 3.0b
- With 2 terminals (supports 8-9 users)
- Hard drive
- Floppy
- Xenix Multiplan, etc.
Sanyo MBC-1000
- Z80A
- Built-in monitor
- Single floppy
- External 10MB HD
- Keyboard
- CP/M, WordStar, CalcStar, etc.
email thadh(a)microsoft.com with offers (local preferred due to the size
of this stuff)
You are correct about the slowness of the 1541, and I was not saying the 64
was 100% perfect, but for the money, the 64 still gives more bang in the
video and sound department. and recently, CMD (Creative Micro Designs) wrote
a new OS called JiffyDOS. it was comaptible with the original ROM, but used
better timing loops that increased the serial bus performance! you just
replace the ROM in the motherboard, and the rom in the 1541 with jiffydos,
and the results were fantastic, just by rewriting the firmware, the 1541 was
now FASTER than a 486 running MS-Hoss with a 5.25 drive. but no matter what
8 bit cpu you use, it is amazing what you can do with 1 MHZ by proper
software design.
I also timed the performace with a stopwatch, and I loaded a large music
editor from the same disk, 1541 drive, with and without jiffyDOS
stock 1541 1541 with Jdos
1 minute 20 sec 10 SECONDS!!!
pretty spiffy eh?
Phew. Well I've pruned through my mail and made it to the bottom.
To all of you who sent me personal e-mail over the last week - I'll
get back to you in the next couple days. I'll also work on processing
all the unsubs.
On topic - this weekend I picked up some stuff:
Need info on:
Acorn monitor with strange connector, switch selects modes I, II, III
5 1/4" floppy drive for Atari ST (no brand)
Just gloating:
Apple IIgs with monitor and 5.25" drive (ROM 1) for $15
Stack of needed manuals at 0.39$ ea. (I'll post duplicates)
Apple Disk III drive
Franklin Ace 1000
An interesting one - I already have a 1000 and unforch. I think this
one is too damaged to save (crushed case - cracked board). The thing
is it has a strange disk controller which the Disk III (as in Apple
II disk drive) was attached to. It also has a video board of some
kind. No part numbers but I'll play around with it some more later.

Hello there, I an fairly new here, but I am interested in all kinds of
hardware and software hacks.
Someone out there mentioned the 'sophistication' of the Apple ]['s video
addressing, saying that the
RAM refresh steals CPU cycles, Apples method is worse than a kludge, it was
simply a crufted idea. yes, the Disk II is an elegent kludge,as ALL of my
homebrewed electronic gear are kludges just to make them work!<G>. My first
computer was a Commodore 64, and comparing it to apples(not oranges :0) the
64 is WAY more advanced, and it too shares a medium populated motherboard. I
can do 90% of the multimedia stuff on the 64 as you can with a P-133! my
point being, the Apple and 64 both had 6502 compatible proccessors, but the
6510 used by the 64 has smarter memory mangament, and it is fast enough to
refresh the ram AND do sprite graphics AND use bit mapped memory. adding
perhiperals to the 64 via the serial bus worked NICE, and I can prove
history is repeating itself. Look at the new USB (Universal Serial Bus)
standard, where they want to run evrything from keyboards, mice, modems
etc... the Wintel croud calls it BRAND NEW IDEA, but we did this 10 years or
more ago. I got a good taste of Apple's machines in school, and they were
ok, but nothing I would ever try to own. the only drawback to the C=64 is
that it did not have an expansion bus built in, however it did have a
expansion connector which you can hook up a passive backplane to.
I dont have much classic stuff but here is what I have:
3 CoCo's, one with 1 floppy drive, all 16K machines. the floppy drive as
sold by radio shack is actually an IBM compatible 5.25 drive! the ONLY
difference is an attempt by radio shack to foil anyone trying to USE off the
shelf floppy drives by placing the ribbon connector on the opposite side,
and because of this, the data cable was too short to connect the normal
drive. But the controller card and pinouts are all the same IBM standard.
The reason was that radio scrap wanted to charge you $400 for adding a drive
that costed $50 max at the time. so IBM drives are not limited and can be
used in any way, it just takes more hacker skill to implement it.
3 Commodore 64's, one is souped up with JiffyDOS, 1 meg REU, and 1.6 MEG
floppy drive.
2 Commodore 128's both work and was extensively used, and because of this,
they are on the verge of expiring... the keyboards on the 128's were never
as durable as the 64's.
1 IBM XT works, but needs XT keyboard.
1 IBM 286-12, works too, and loaded with MORE TTL than the XT was....
Now the rest of the bunch are not classic, but I will place them here to
make the list complete.
1 Acer 386-33, used as a file server
1 home built AMD 586 machine which is what I am composing this message from.
I was looking through a book I had picked up a year or so ago called
"The Elementary Commodore 64". Towards the front amongst the
description of various types of peripherals available for the C64 under
the title "Other Gadgets" was this:
Z-80 CP/M -- This cartridge goes right into the cartridge slot to turn
your machine into a Z-80 base computer enabling you to access the vast
array of CP/M software. With over 2000 CP/M software programs
available, there is little you will not be able to access.

Hi Steve,
Yours was the only one response I get (since now) from C=1570 owners
Mine was made in Germany (did you buy it in the U.S.?)
Ciao
A place in my location called surplus exchange, has about a dozen pcJR's on
a skid. I didn't find any power supplies, but by the looks of the place,
they could be anywhere. Let me know what to look for when I go back and
I'll see if I can't rescue some more. (assuming the old lady lets me). I
know the PC JR I bought, has a Parallell port on the outside, which I
learned only today is a "Side-car". I have dozens of composite mono and
color monitors from my apple// and Zenith collections. I also managed to
scrounge out of this pile, [one] keyboard with cable, and [one] joystick
and about 5 or 6 cartridges. The other PCjr,s seemed to be alone. Let me
know what to look for on the CPU's and I can go through all of them one by
one. If anyone else want's one, let me know and we can see what we can do.
Last trip there I got a TI99/4a, atari 800, 1050 drive, 410 drive, Tandy
COCO 1,. Commodore 1741 drive, Commodore mps 803 printer (I think) it works
good. And an apple//+ for parts. I paid 35 for everything. I noticed this
pallete of Jr's but I sure as heck didn't see any monitors, keyboards or
power, except the one keyboard I did find elsewhere in the building.

Subject: Apple III's for sale
FYI ... I have 5 Apple ///'s for sale (improved re-release
version), including original monitors. Some with 512K memory. Some
peripherals also, including spare parts, Corvus 20 meg server with
related Apple III interface cards. Would prefer selling at least
computers/monitors in bulk and will consider any reasonable offers. I
understand there are now thriving museums and actual user groups still
utilizing. If NOT interested, would appreciate any leads for other
possible contacts. These machines actually served us quite well !
Thanks
