GALEP-4

[r6502]

Hello all,

I just bought at ebay a used older GALEP-4, that should be able to program vintage EPROMS and works on older PC's parallel port.

Device seems to be running for reading very well, but for programming the devices I do not see what programming voltages are used for a specific selected chip. For example, for a 27C32 is available with different programming voltages from different manufacturer so I have always to look into different data sheets what programming voltages are used for the specific chip. In their software I have only the option to choose a specific chip, no further informations are shown like programming voltage and programming algorithm.

I asked the  manufacturer  if / how it is possible to define a new chip, but got the answer, that they do not like to give details how chips are defined.

It would be much more convenient, to specify the pin layout e. g. 27C32 and specify the programming voltage and the programming time / algorithm.

is there a programmer on the market that fulfils this?

I also tried a TOP3100, but this fails also programming some EPROMS.

Need VPP=25V

Any suggestions?

sadly you have to check the specs / supported ic list of many programmers to find the one you need ...  vs brand and ic model(s)

on some new tl866 gen 2  / rev 2          people added  coin cell in the supply line to boost the programming voltage  ...  could be a solution ?

I've never wasted my money buying cheap device programmers. The ones I almost exclusively use are BP Microsystems.

If you wait around long enough on eBay, you can sometimes find decent deals on older BP-1200 and BP-1400 device programmers, including the DIP-48 socket module. I've seen several decent deals on those go by that I've passed on because I have more device programmers than I need now. Those have support for 25V VPP NMC27C32 ERPOMs. Those older models use an LPT interface, and haven't had any software updates for a few years.

The ones I use now are the newer BP-1410 and BP-1610 which have USB interfaces, and currently receive regular software updates. Those aren't cheap on eBay though, a few hundred $ or so currently.

The GALEP programmers used to be the industry standard in Europe for several decades. These where not particulary cheap either. Going for a printer-port only solution is a dead end nowadays. I used to have a printer-port GALEP3 but it is long gone due to lack of computers with a printer port.

Ah, OK. Well then, what device programmer would you buy to program a 25V VPP NMC27C32 ERPOM?

Most likely someone that needs to program a NMC27C32 isn't all that concerned about dead-end solutions.

my needs:
Vpp: till 25V, would be fine, if it is independent selectable from the EPROM type.

Interface: parallel would be ok, USB or serial preferred.

The thing I 'm struggling with the GALEP-4 is for example I have a  3 different  27C32 from different MFGs with different Vpp voltages. In the application that comes with GALEP-4 one can only select the chip. When you selected the chip, you do not knew, what Vpp and what programming algorithm they are using. When the chip is not listed in the list, choosing a similar chip but I do not knew what they are exactly doing with the chip during programming. If Vpp is to high the chip will be damaged.

I wold prefer to select the pinout of the EPROM (like 2732), than select the the Vpp voltage, and the programming algorithm. With programming algorithm I mean  choosing between fixed programming time per byte and selecting this time or an "intelligent" algorithm with variable time like shown in the attacked diagram, that came up with larger memory sizes.

When I was a student and earned additional money in a small local electronic company in the middle of the 1980 years  we had a programmer that worked in this way.

Anybody an Idea?

the one i have for sale  support them   loll

remove some of them  loll   who dont match 27c32

Hi,

Advantech LabTool 48 (_LV/XP/UXP) or its Elnec/Dataman/B&K Precision rebrand.
You can often find them on EBAY.
They all need LPT (except _UXP).
_UXP to work under Win7..10.
You need to buy a license for 2 years.
To work under Win XP (LPT) you need to install SW to support older versions V8.32.03 (Free).

That Figure 7 AI00775B diagram appears to be the SGS-Thomson M2764A Fast Programming Flowchart.

One of the things that I like about the BP Microsystems device programmer software is that when you select a device to program, it provides information about the programming algorithm, so you can verify that the device selection matches programming information you may have from device datasheets. For example, the M2764A device information it provides appears to match that SGS-Thomson M2764A Fast Programming Flowchart.

Any suggestions?

You could take a look in the file "Program Files/GALEP32/def/galep32.def".  The 20th column appears to be the programming voltage, and matches the VPP in the datasheets for the NMC27C32 (25.0V), NMC27C32B (12.75V), and NMC27C32H (25.0V).

I'm glad i got my Galep-5 a few years ago.

There is no way the seller will ever get that amount of money.
