Post by thread:[OT] DIY eprom programmer

I am also interested as I have a bunch of surplus 27C64 - 27C256 devices that I will be using in an upcoming 'bot design. (Yes it will use at least one PIC for motor control, but the brain will be an HC11). Software to *do* the proramming would also be nice BO) Dan On Wed, 31 Mar 1999 11:36:42 -0500, Ryan Pogge wrote: >I am looking for a DIY eprom programer for the 27xxx series.. >any urls I can look at? > >Thanks, >Ryan >

I didn't write it, I found it on the web somewhere. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelgKILLspamlpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki Ju Jitsu | | England | | \--------------------------------------------------------------/

> I am looking for a DIY eprom programer for the 27xxx series.. > any urls I can look at? A few days ago, I did some searching on the net. That's what I found about DIY EPROM programmers (for DOS): http://www.bos.nl/homes/waklos/ A nice prommer from Willem Kloosterhuis which programs: 27C64 .. 27C040/4001 28C65 .. 28C040 28F64 .. 28F040 29F64 .. 29F040 serial eproms 24C02 .. 24C65 PIC 16C84 and 16F84 microcontroller PIC 12C508 and 12C509 An impressing list of devices and you can build it totally for free! But you'll have to make yourself (or by from the author) a doublesided 160mm x 100mm PCB. In the next weeks he wants to release a new PCB revision. http://www.zws.com/products/epromr2/index.html A more simple design, to simple to release a pcb layout (that's what the author thinks about it). It can program: 2764 8192x8 EPROM 27128 16384x8 EPROM 27256 32768x8 EPROM 27512 65536x8 EPROM 27010 131072x8 EPROM 27020 262144x8 EPROM 27040 524288x8 EPROM 831000 131072x8 mask ROM This programmer is named EPROMr2 and it's free. EPROMr3 should be released in future, but it won't be free anymore. And last an URLs of a Link Page you can have a deep look into: Computer hardware projects at http://fagersta.com/electronics/hwprojects.html I haven't build or tested any of the designs yet but they might be useful Florian
