Jeff,
Yes, I would like you to have a look at it. My thought was RAM. But my desoldering skills are not adequate. I managed to ruin an M102 board trying to remove the ROM. Please tell me what to send and to where. Thank you Robert From: M100 [mailto:[email protected]] On Behalf Of Jeffrey Birt Sent: Wednesday, March 24, 2021 10:36 AM To: [email protected] Subject: Re: [M100] Broken NEC 8201a The black screen is an indication that the LCD is getting power but not getting initialized properly. This is most likely because the system is not booting properly. The RAM modules can fail causing a no boot situation, or it might be stuck in rest, etc. If you want, I'll have a crack at repairing it. They are very similar to the M100/T102 as far as fixing one.

Hutchins Sent: Wednesday, March 24, 2021 11:50 AM To: [email protected] <mailto:[email protected]> Subject: [M100] Broken NEC 8201a I have an NEC 8201a that will not run. On startup I get the black screen that does respond to the contrast control. I don't believe it is the typical capacitor problem. I have checked a few voltages and they appear OK. The unit is in good physical condition. I also have several Model 100s and a 102 which I have been able to upgrade the ROMs to Y2K spec and manage a few repairs on. I am of two minds about the NEC though. I might just sell it as is (make an offer?) or if someone would like to have a go at repairing it, I would be happy to pay for that. Please advise. Thank you Robert J. Hutchins
