RE: Toeprom: eprom programmer
I suppose the previous owner (or owner before the previous owner) modified the unit itself. I managed to open the case (I remeber vaquely that Toeproms were not cased?) and am reengineering the modifications. All jumpers are wired to the EPROM connector, so it is possible to find out what the jumpers imply. It is surely for 27512 support. When i know why and how I will report here, thanks for the replies. -Original Message- From: Maarten ter Huurne [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 07, 2001 00:57 To: [EMAIL PROTECTED] Subject: Re: Toeprom: eprom programmer On Wednesday 06 June 2001 19:47, you wrote: There are four jumpers on the top marked 27512, 32 etc. Does anyone know what the function and settings of these jumpers are? I have a Toeprom as well, but mine doesn't have any jumpers. Probably there are different versions.

Looks nice, not so good and not uptodate manual. Not a high quality program inside, but I have the MAD/Dick van Vlodrop version (including sources) on disk. (will come to www.geocities.com./msxhans, mail me if you want it now) Jeremy Wiermans released a new program for TOEPROM, called 2EPROM. It can handle 2764, 8 kB, 27128, 16 kB and 27256, 32 kB EPROM´s. 2EPROM is much better as the software that was supplied with the hardware and it´s Public Domain. This program is reviewed in MSX-Info Blad 14. You can contact the publisher of MSX-Info Blad, Rinus Stoker, to receive this program. Jeremy maybe wants to adapt his program for 27512 and EEPROMS. But here my question: There are four jumpers on the top marked 27512, 32 etc. Does anyone know what the function and settings of these jumpers are? 27512 is a 64 kB EPROM, 27256 is a 32 kB EPROM. It´s also possible these jumpers are used to determine the ´programmeervoltage´, like 5.0, 12.5, 21.0 and/or 25.0V. 2EPROM can do all the work for you and determines the best usable EPROM and `programmeervoltage`. I hope this info is to your help. Greets, Gerrit van den Berg MSX-Info Blad -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

To me, it seems to be an eprom selection. You should connect the jumper in the right position according to the eprom which you are programming.
