Re: [volt-nuts] Solartron 7081
Joe,
I really want to experience using the eprom programmer first hand but
haven't been able to find a USB based on that's below $100 that says it
supports VPP of 25v. I think to spend more than that on tools that may not
be used again isn't smart...although I have broken that guideline many
times! I think using a USB to RS-232 or USB to parallel adapter makes for
a good rabbit hole too. I successfully cancelled the programmer I already
ordered as it didn't have high enough programming voltage even though it
said it supported the TMS2564-JL chips.
So, Joe, I'd like to take you up on your generous offer to read the old
ones and program the new ROMs. I was able to confirm this morning that
the ROMs I ordered are the correct versions. They should be here to my
house by Thurs this week. I'll reach back out to you once they've arrive.
I've also ordered a new battery for the B1 real time clock. It is dead.
That should be here tomorrow. Will be interesting if the battery is part of
the boot up problem.
Thanks
Rick
If you have the pocket depth then I would suggest a Galep-5 (made by
Conitec) EPROM programmer.
I have its baby brother (Galep-4) but that needs a parallel port.
It's a USB device and will handle the older stuff like 2564s quite happily
and also the new serial EEPROMs

The older programmers, generally, require a Parallel Port. Parallel Ports
seem to have vanished though I have a Win7 machine with one. Haven't tried
to use any of the older software with it though.
I have several older machines with WinXP and these almost all came with a
Parallel Port. And, you could add additional Parallel Ports with PCI
cards.
I have three programmers connected to one of my computers.
My favorite computer for this is the Dell Latitude D610 which I think was
the last Dell Laptop with a Parallel Port. Also has USB and Serial. These
seem to be relatively cheap on theBay. Depending on the 'total cost',
might
be worthwhile to get an older computer with WinXP and an older programmer
rather than the usual several hundred dollars for a newer USB programmer.
I just looked at my 7081's and (re)discovered that they both have their
'Calibration Seals' in place when calibrated by Ametek (formerly Solartron)
several years ago. I would like to avoid opening them if possible. I'll
chase down the EPROM files referenced earlier in the thread to be able to
compare your chips with. If your chips are bad (can't be read or
programmed), I'll use those files to program your new chips.
I went looking for my stash of EPROM's but, so far, I can't find it. I
don't remember if I have those chips or not. I did find some TMS2516's so
maybe I do have the chips if I can find the 'mother lode'. Hopefully, you
can get the chips.

Hi Joe, what about just building a converter?
Most PIC programmers output 11-13V so this could feasibly be adapted.

Rick,
I doubt you will be able to get into this arena for less than about $200.
That would need to include a programmer and a computer with WinXP. The more
older equipment you have, or want to have, the more you will be motivated to
develop this capability.
If you are old, like me, and you got computers many decades ago, like me,
and you keep things, like the original packaging, like me, you might have
the computers that would work. Then, you might be able to get a programmer
for about $100+/- that would need a Parallel Port and be able to do the
programming.
However, happy to help any way I can. Just let me know when you ship. My
address is @ WB4BPP.
If you are not a HAM, let me know and I'll send you the particulars via PM.
I downloaded the 7081 EPROM files from the Solartron group provided by David
Partridge and will use those to compare yours to and program/reprogram your
chips to.
I don't know if the battery is a problem with boot up or not but I suspect
David might.

Andre,
I hadn't thought about your potential solution but might be worth a try.
The issues that I recall involve timing of the various pulses as well as the
amplitude. Reading the chip is seemingly a much less problematic issue.
However, with programming, timing becomes a more important issue. I suspect
if you slow the process down a lot and make sure the timing is appropriate
(meaning when the 'final voltage values' have stabilized) it might work.
However, with old computers, its faster and cheaper to just buy an old
programmer that supports the chip in question.
I would be interested if anyone is able to address this and find a workable
solution.
Joe

Rick,
It has been a long time since I got my two 7081's but I remember one of
them would not work with the dead battery. I replaced it and it came up
fine.
I did have a problem with the battery leaking and causing some corrosion.
It wouldn't hurt to give that board a close inspection as the battery
leakage went under some components.
Also, I wanted an older programmer that also supported PAL/GAL and the
higher programming voltages. Xeltek makes some decent programmers and I
ended up with the SuperPro 280U. I paid around $200 for mine and it
supports thousands of older parts including some of the older and more
exotic memory that the Chinese clones can't do.
Xeltek also has the software and manual for downloading which is great for
a discontinued product.

No a flat battery won't prevent the earthy processor from booting. It just
means the system boots to "Initialised" rather than to "Resumed".

be used again isn't smart...although I have broken that guideline many
times! I think using a USB to RS-232 or USB to parallel adapter makes for
a good rabbit hole too. I successfully cancelled the programmer I already
ordered as it didn't have high enough programming voltage even though it
said it supported the TMS2564-JL chips.
So, Joe, I'd like to take you up on your generous offer to read the old
ones and program the new ROMs. I was able to confirm this morning that
the ROMs I ordered are the correct versions. They should be here to my
house by Thurs this week. I'll reach back out to you once they've arrive.
I've also ordered a new battery for the B1 real time clock. It is dead.
That should be here tomorrow. Will be interesting if the battery is part of
the boot up problem.
Thanks
Rick
If you have the pocket depth then I would suggest a Galep-5 (made by
Conitec) EPROM programmer.
I have its baby brother (Galep-4) but that needs a parallel port.
It's a USB device and will handle the older stuff like 2564s quite happily
and also the new serial EEPROMs

Rick,
The older programmers, generally, require a Parallel Port. Parallel Ports
seem to have vanished though I have a Win7 machine with one. Haven't
tried
to use any of the older software with it though.
I have several older machines with WinXP and these almost all came with a
Parallel Port. And, you could add additional Parallel Ports with PCI
cards.
I have three programmers connected to one of my computers.
My favorite computer for this is the Dell Latitude D610 which I think was
the last Dell Laptop with a Parallel Port. Also has USB and Serial.
These
seem to be relatively cheap on theBay. Depending on the 'total cost',
might
be worthwhile to get an older computer with WinXP and an older programmer
rather than the usual several hundred dollars for a newer USB programmer.
I just looked at my 7081's and (re)discovered that they both have their
'Calibration Seals' in place when calibrated by Ametek (formerly
Solartron)
several years ago. I would like to avoid opening them if possible. I'll
chase down the EPROM files referenced earlier in the thread to be able to
compare your chips with. If your chips are bad (can't be read or
programmed), I'll use those files to program your new chips.
I went looking for my stash of EPROM's but, so far, I can't find it. I
don't remember if I have those chips or not. I did find some TMS2516's so
maybe I do have the chips if I can find the 'mother lode'. Hopefully, you
can get the chips.
Joe
