I don't know if mine is the same as Rik's, but I do have the Landmark
"Professional PC Diagnostics" kit that comes with ROMs for both the
XT and AT. I'll be happy to send an image along if you think it
would help.

I've got one of these--actually a no-name, but the same Taiwanese
unit. At one time, I think these were also sold under the "Sunshine"
name. You could get them with different "heads"--anywhere from a
single ZIF socket to 8 or so; maybe even 16. I have the 4-socket
version.
You've answered your own query. This board is strictly 5150/5160/XT
clone territory. IIRC, even a PC AT doesn't work--at least with the
software that I have (I haven't tried JDR's). I believe that this is
due to many CPU-based timing loops. I remember patching the code to
detect the board so it would run in a 386/20, only to have it fail to
program EPROMs, whereupon I gave up and stuck it back in the XT,
there to stay until the present.
This forms the basis of my suspicion that CPU loops are used
exclusively for timing--not a really bad idea back when the world was
filled with 8088 systems. Certainly, it wasn't alone in this
respect.
Get that 5160 going and you should be fine. I suspect though, that
you're faced with a chicken-and-egg situtation--you need to get the
EPROM burner going so you can get the 5160 running.
Source code for the programming software should make things easier to
modify for faster machines, but I suspect that it's unobtainium.
Disassembling is another option, but not one that I'm interested in,
as I have a parallel-port driven programmer that can still handle the
older EPROMs just fine.

Does anyone have a datasheet for a Texas SN7523N?
I have a datasheet for a Signetics SN7523 (dual core sense amp), and was
expecting that the TI part would be equivalent, but it seems to behave
differently. I'm trying to figure out if I have a bad part or my
assumption that they're equivalent parts is mistaken.

Hi,
I have an old EPROM programmer for the PC. It uses an 8 bit ISA card
labeled "MCT-EPROM". JDR used to sell these in the 1980's for 24 & 28 pin
EPROM programming. It is a fairly simple device but it doesn't appear to be
working.
JDR still has the software on their FTP site for the programmer, I think. I
believe it uses the "MOD-EPROM" software from the "MOD_EPRO.ZIP" file. It
appears there are several pieces of software on the JDR site which support
this programmer
Whenever I start the MOD-EPROM software it says it cannot find the
controller board. It is looking for a device a 0x2A0 but apparently can't
find it. The software does NOT allow the IO address to be changed and there
are no configuration jumpers on the controller board.
The ISA controller board installed in 486sx (25 MHz) but the software could
not find it. I tried with a P3 (450 MHz) and got the same result.
Does anyone have one of these EPROM programmers and can lend me a hand? I
need to confirm some things in order to determine if this part is working or
not. It may be I am using the wrong software or too fast of a computer.
Thanks in advance for any help.

Not as high tech as others, but I still love the Commodore's. C64's, PET's
SX-64's (drool!) and their associated hardware, books and software.
If anyone is looking for a good home, please let me know.
I'm in Colorado, just south of Denver.
Thank you.
All:
I?m looking for the two following Dr. Dobb?s articles on the Mac:
::Jan 1985 "Fatten Your Mac" by Thomas Lafleur and Susan Raab
::Sep 1985 ?SCSI Your Mac, in MAC Toolbox? by John Bass relating to
adding a home-brewed SCSI interface to the Mac 128/512.
I have one of the DDJ article compilation CDs (Volume 11) but it only
starts at 1988. I would be grateful if someone with access to these issues
could make scans of them or point me to an on-line copy. Googling this
morning didn?t produce much other than TeX indices.
Thanks!
Rich

Thanks.
I thought of both, but still too power-hungry. How about something
that runs off of a wall wart? My DSL modem with ARM7 CPU runs Linux
and supports ethernet--it just don't have a sound chip. I don't need
video a CD-ROM, hard disk or floppy; just network access with the
ability to flash from the network. Even one of the VIA C3 boards is
more than I need.
Any other ideas?

The cctalk server seems to have swallowed up postings after 22 May,
so I'll post this one again:
There are some very cool videos at:
http://blog.wfmu.org/freeform/2008/05/a-brief-history.html
The first film looks to be late 60's and is from Barclay's Bank. I
can identify S/360 and CDC 6000 gear easily; but not some of the
other stuff (ICL?).
The last film clip from a Britcom features an "intelligent" luggable
named Bourenmouth, What machine was it before it received its paint
job?
Cheers,

Hello. I should like to obtain one copy of the NIC 7104 (Arpanet Protocol
Handbook). It was published many years ago by SRI but actually is completely
dissapeared. Could someones help, please ?
Thanks and Greetings

Hi,
I am trying to revive an original IBM XT motherboard using an AWARD
POSTcard.
Unfortunately, I do not have the manual for the POSTcard.
Does anyone have one or can help with the switch settings? The XT uses IO
port 60h for the POST code whereas the AT uses port 80h.
I know the POSTcard works since it gives proper codes on AT class machines
(486 and newer)
Thanks in advance for any help!
Andrew Lynch
